The choices usually in conflict are, should we fix the root cause of the problem or should we just manage the problem?
The case of the pandemic shows that there were those who opposed the solution of the problem with Covid 19 vaccines to attack the root cause (the virus) of the problem to minimize severity of infection or chances of hospitalization or changes of death; and those who just wanted the Covid 19 to be managed in such a way as to facilitate the reaching of natural immunity regardless of death levels or severity of consequences of just managing the Covid 19 problem.
In the case of the Covid 19 problem most countries if not all, chose to attack the root cause problem with the vaccine.
In the case of the environmental pollution problem, the international and local community is focused since 2012 on managing the pollution generation problem instead of fixing the root cause of the pollution generation problem(distorted market prices).
In the case of the pollution generation problem most countries if not all, chose to avoid fixing the root cause pollution generation problem with green markets in 2012 as the environmental cost internalization as vaccine, and went instead with the way of managing the pollution generation problem with environmental pollution management based markets.
And this raises the question, is the goal of dwarf green markets like climate change markets to reach a level of natural environmental immunity locally and globally through pollution management? While leaving the root cause of the pollution generation problem unfixed?
What do you think? Yes, then why? No, then why not?

Dear Lucio Muñoz,
I will also answer your question by referring to the economic crisis indirectly caused by the SARS-CoV-2 (Covid-19) coronavirus pandemic in 2020. When the World Health Organization announced the state of a global epidemic at the beginning of March 2020, i.e. of the pandemic, the reaction of the financial markets was too nervous, too deep, too exaggerated. The behavior of stock exchange investors and the speculation of large financial institutions worked. Some governments fearing that there would be a shortage of beds in hospitals for seriously ill people with Covid-19 introduced lockdowns, which caused serious economic problems in many industries and sectors of the economy. In order for these decisions not to cause protests from the public, the government granted non-returnable subsidies to business entities on the basis of printed money in the public finance system cooperating with the central bank. These actions started an increase in inflation in 2021. Now, when we ask whether lockdowns have been applied to selected sectors of the economy in the context of rapidly developed vaccines and the scale of the severely ill with Covid-19 population and deaths from Covid-19 and comorbidities, different answers are coming up. The difference between the so-called the health crisis caused by the pandemic announced by the WHO and the climate crisis is that the pandemic appeared suddenly and was something new, and the climate crisis is being realized as a long-term, multi-year process. An interesting point is that so far WHO has not lifted the pandemic state, despite the fact that in many countries the pandemic has already been replaced with a state of increased virological risk, the anti-pandemic restriction has been lifted, the number of people seriously ill with Covid-19 has significantly decreased and the government has already recognized other problems as more important, which should be solved systematically and with the use of funds from the public finance system of the state. Such problems are currently double-digit and still growing inflation, and raised interest rates. by central banks and the economy entering a recession, energy crisis, food crisis, climate crisis. However, now referring to your question, I state that what you define as dwarf green markets, i.e. incomplete application of sustainability, pro-environmentalism, pro-climate in economic policy, is a kind of prosthesis of actions that should be implemented as part of a full pro-environmental and pro-climate transformation of the economy and are not realistically implemented. The reason is resistance in the spheres of business and politics, the lobby of large mining, mining and energy companies, as well as refineries operating in the sector or for the benefit of the dirty combustion energy sector. These sectors are key factors in slowing down the green transformation. Therefore, instead of fully carrying out the pro-environmental and pro-climate transformation of the classic growth, brown, linear surplus economy into a sustainable, green, zero-emission, zero-growth economy and a circular economy, prostheses of these processes are created, i.e. what you refer to as dwarf green markets. Thus, a short-sighted approach still prevails instead of long-term and strategic planning. Ad hoc measures are still being taken instead of introducing profound changes in the area of ​​pro-environmental and pro-climate transformation of the economy. The problem is still being swept under the rug instead of solving the problem in a multi-faceted manner and reaching the source of the problem. Contrary to the situation from the 1st wave of the pandemic (spring 2020), we know what to do in terms of the pro-environmental and pro-climate transformation of the economy, but we still do not fully do it, assuming that it will be done somehow. On the other hand, there is little time for a full pro-environmental and pro-climate transformation of the economy, thanks to which it would be possible to significantly slow down the global warming process, which has been progressing since the first industrial revolution and accelerating in recent years, and to significantly reduce the scale of the potential negative effects of the climate catastrophe, which may already appear in the current XXI century. In this way, instead of carrying out a complete, thorough (with reaching the source of the problem and taking into account a long-term strategy) pro-environmental and pro-climate transformation of the economy, prostheses of this process are created and dwarf green markets are created as you have described it. For example, companies and enterprises add to their missions and development strategies the issues of achieving the goals of sustainable development, pro-environmental and pro-climate responsibility of business, although they do not really do much in this matter. They present their new green missions in advertising campaigns with their new product and service offers, because they see that the level of pro-environmental awareness of citizens, i.e. their potential customers, is growing. On the other hand, penalties for introducing toxic waste into the natural environment, for CO2 emissions to the atmosphere, for poisoning the natural environment and increasing the incidence of various diseases occurring in humans and animals, etc., are not always allocated to solving these problems, to increasing the scale activities implemented under the environmental and pro-climate policy. Probably many people still do not realize that it is not much time left.

How do you think COVID-19 countermeasures taken by states and governments comply with the human rights guarantees established by national Constatutions and the International Human Rights Treaties? Among those measures are :
-mandatory vaccination
-lockdown
-mandatory usage of masks
Relevant answer
Answer
On the issues of COVID-19 vaccination campaign was conducted that the public have to get vaccination in the Government Hospitals, Health Centers, and Emergency Centers but those were willing to take the vaccination according to their physiological conditions of the body.
People have considered if they are taking the tablets regarding cardiac, pressure, etc.
Here, the issue of Human Rights came to an individual's interest and decisions but there is no compulsive vaccines in any part of the world.
In Europe most of the elderly people have not recognized most of the mushrooms pharmaceuticals have been emerged during the Covid pandemic periods.
The confidence among the people determine the willingness and desire to take vaccine against COVID 19 transmission.
It is purely related to human rights issues than any other measures.
International Human Rights Treaties have helped the people who want to have vaccination in time or to reject if they are healthy against the virus diseases etc.
It is general recommendations to have vaccination for the community to save and protect by yourself. That's all .

Well,
I am a very curious person. During Covid-19 in 2020, I through coded data and taking only the last name, noticed in my country that people with certain surnames were more likely to die than others (and this pattern has remained unchanged over time). Through mathematical ratio and proportion, inconsistencies were found by performing a "conversion" so that all surnames had the same weighting. The rest, simple exercise of probability and statistics revealed this controversial fact.
Of course, what I did was a shallow study, just a data mining exercise, but it has been something that caught my attention, even more so when talking to an Indian researcher who found similar patterns within his country about another disease.
In the context of pandemics (for the end of these and others that may come)
I think it would be interesting to have a line of research involving different professionals such as data scientists; statisticians/mathematicians; sociology and demographics; human sciences; biological sciences to compose a more refined study on this premise.
Some questions still remain:
What if we could have such answers? How should Research Ethics be handled? Could we warn people about care? How would people with certain last names considered at risk react? And the other way around? From a sociological point of view, could such a recommendation divide society into "superior" or "inferior" genes?
What do you think about it?
Relevant answer
Answer
In certain condition i guess. if it' related to gene diseases (especially for y- chromosome). Because people follow their father's surname. But it's also conditional.
But i can say surname itself doe not affect your immunity. cuz if woman marries some guy and changing their surname it wouldn't affect their immune system.

Cancer incidence is increasing globally. It is widely believed that increased life span is the main reason cancer risk overall is rising. A paper published in the Lancet reports that delays in screening, diagnosis, and treatment due to the COVID-19 pandemic could lead to excess cancer deaths, and slow or even reverse the declining trend in mortality projected for some cancers. https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(22)00111-6/fulltext
Furthermore, the report by Harvard Medical School researchers at Dana-Farber Cancer Institute and colleagues from other institutions, suggests that COVID-19 has complicated the treatment for patients with cancer. "In patients with cancer, COVID-19 can be especially harsh. This is likely because many of these patients have a weakened immune system—either as a result of the cancer itself or the therapies used to treat it—and are therefore less able to fight off infection by the new coronavirus". https://hms.harvard.edu/news/covid-19/cancer-interplay#:~:text=In%20patients%20with%20cancer%2C%20COVID,infection%20by%20the%20new%20coronavirus
In 2021, a research team led by Zhou highlighted the clinical and molecular similarities between cancer and COVID-19 and summarized the four major signaling pathways at the intersection of COVID-19 and cancer, namely, cytokine, type I interferon (IFN-I), androgen receptor (AR), and immune checkpoint signaling. They also discussed the advantages and disadvantages of repurposing anticancer treatment for the treatment of COVID-19. However, Professor Abdollah Jafarzadeh and his research team, in their paper "Review SARS-CoV-2 Infection: A Possible Risk Factor for Incidence and Recurrence of Cancers" explored another aspect of the interplays of COVID and cancer. Their findings which are published in the International Journal of Hematology-Oncology and Stem Cell Research might shed some light on the dark corners of the potential interactions of COVID-19 and cancer development. https://ijhoscr.tums.ac.ir/index.php/ijhoscr/article/view/1408
Jafarzadeh et al. reported that the patients with some types of cancers may be more vulnerable to SARS-CoV-2 infection compared with the non-cancerous individuals, due to their immunocompromised state resulted from malignancy, chemotherapy, and other concomitant abnormalities as well as perhaps greater expression of angiotensin-converting enzyme 2. Moreover, they reported that clinically recovered COVID-19 individuals display immune abnormalities that persist several months after discharge.
The lymphopenia-related immunosuppression, functional exhaustion of cytotoxic lymphocytes (such as CD8+ cytotoxic T-cells and natural killer cells), hyperinflammatory responses, oxidative stress, downregulation of interferon response, development of the myeloid-derived suppressor cells, downregulation of tumor suppressor proteins and perhaps reactivation of the latent oncogenic viruses may directly and/or indirectly play a role in the cancer development and recurrence in severe COVID-19 patients. https://ijhoscr.tums.ac.ir/index.php/ijhoscr/article/view/1408

I've been interested in COVID stuff recently. Most of the current detection/diagnosis strategies need amplification. I can understand that RT-PCR can probably break the capsid because of the high-temperature processes. But how does that work for isothermal methods like RT-LAMP, since the temperature is not that high?
Also, if we want to directly detect or do something with the viral RNA, do we need to break the capsid and release the RNA? If yes, is there any established protocol? Many thanks!

Due to the energy crisis, the government's promotion of dirty combustion energy and the restriction of the development of emission-free green energy, will air quality in the heating season significantly decrease and the incidence of respiratory diseases and Covid-19 increase?
Various types of hard coal, lignite, pellets and firewood are allowed as fuel in Poland. However, even before the current energy crisis, in previous years it happened that some citizens threw various types of waste, including, for example, tyres, into the cookers heating their homes. As a result, air quality in Poland during the heating season (autumn and winter) was very poor in many cities and towns, failing to meet European Union standards. In many towns and cities there are no municipal guards or other services to control what is thrown into the heating cookers. However, there are already efficient systems in place in many countries to control what people heat their homes with. As part of the construction of such a control system, drones may be used, for example, which fly up to the chimney of a house and examine the composition of the fumes contained in the smoke coming out of the chimney. In Poland, only in a small number of cities, towns and villages are such modern methods used to control what citizens heat their homes with, i.e. what is thrown into the heating cookers. Because the current government, which has done almost nothing about this for the last seven years, so the state of the air in many cities is bad. This results in the deterioration of the health of citizens who inhale toxic substances contained in the fume-polluted air. Many citizens are dying prematurely due to respiratory diseases and other diseases resulting from inhaling carcinogenic toxins in the air. Due to the fact that the present government has impeded the development of renewable and emission-free sources of energy and financially supported the coal-based power industry, at present still 3/4 of the electricity and heat generated in Poland comes from dirty exhaust gas power. In order to make such statistics submitted to the EU authorities look a little better, the government-controlled Central Statistical Office has classified firewood as a renewable energy source. From an ecological, environmental and climate point of view, this is absurd and the government's treatment of citizens as mindless lemmings. The wood approved for firewood is untreated and unpainted wood. But even such wood burned in cookers releases harmful substances, including particulate matter PM2.5 etc. The absorption of these particulates reduces the body's resistance to allergens, to pathogenic viruses. The development of allergies and the incidence of respiratory diseases and Covid-19 increases significantly. Research shows a correlation between the level of PM2.5 etc. and a decrease in the human body's resistance to disease, a decrease in the efficiency of the immune system and the incidence of viral and other diseases. An election campaign is currently underway in Poland in connection with the parliamentary and local elections to be held in 2023. In connection with the election campaign, the main activists of the ruling PIS monoparty are carrying out pro-government propaganda at election rallies in various cities. Analogous pro-government propaganda is carried out in the government-controlled meanstream media. As part of this propaganda, the government is trying to shape the consciousness of citizens by suggesting that Poland is well prepared for an energy crisis, that the government is efficiently pursuing an anti-inflation policy and that the climate crisis is an environmentalist fantasy. Citizens who also listen to and read the existing independent media know that all that is reported in government propaganda is not factually correct. And besides, it happens that members of the government and/or the president of the currently ruling government monoparty PIS suggest to citizens the kinds of actions that are harmful to citizens. For example, at one of the press conferences, at one of the election rallies, the chairman of the currently reigning government monoparty PIS suggested to citizens that they can throw anything into their cookers except tyres, that they can heat their homes with anything except tyres. So that if someone runs out of coal, they can throw in, for example, plastic waste, the burning of which generates carcinogenic toxins. The current government has failed to ensure that there is no shortage of environmentally and air quality compliant fuel during the current energy crisis. The government has failed to implement a pro-environment and pro-climate transformation of the energy sector. The government has blocked the development of renewable and zero-carbon energy sources for 7 years by financially supporting the unprofitable, dirty coal power industry. Inflation is rising and, according to economists' forecasts, real core inflation in Poland will be the highest in Europe in 2023. And the government is introducing further subsidies and handouts for the purchase of fossil fuels, which are becoming additional pro-inflationary factors. Therefore, by the anti-environmental and anti-climate measures of energy policy in Poland, the currently developing energy crisis will be deeper, fossil fuel prices will be higher, air quality will be bad during the heating season. The scale of respiratory diseases and Covid-19 may increase significantly in the next heating season. Besides, the level of diversification of energy sources and the development of green, pro-environmental and pro-climate energy is low. Consequently, the level of energy security is also low. The question that arises is why a large proportion of citizens, estimated to be around a third of the population, still accept this kind of policy. This is how it looks in the country where I operate. And how do these issues look in your country?
In view of the above, I address the following research question to the esteemed community of researchers and scientists:
Due to the energy crisis, the government's support of dirty combustion energy and the restriction of the development of emission-free green energy, will the air quality during the heating season significantly decrease and the incidence of respiratory diseases and Covid-19 increase?

Answer
Dear Abdelhafid Jabri,
I don't know what it is like in other countries, but in Poland, studies have been carried out on the subject. These studies show that in areas where the air quality was poorer, the air was more polluted with toxins emitted from chimneys, the incidence of respiratory and other diseases was higher and life expectancy was shorter. The study also found that the incidence and mortality of Covid-19 was higher in areas with higher levels of air pollution and smog. Data reported by the Ministry of Health shows that more than 90 per cent of people who died from Covid-19 had various co-morbidities, including various respiratory conditions. In view of the above, the correlation that I wrote about above (in my comment on the above question) is confirmed by the results of the study and is related to the fact that most people who died from Covid-19 also had comorbidities resulting from years of exposure to various negative factors of civilisation, including environmental pollution. We do not know what the correlation is between air quality and deaths caused by Covid-19 alone after subtracting the factor of co-morbidities, as there is no sufficiently precise and reliable data to confirm such a correlation. Besides, in the Polish health care system, the qualification of deaths caused by Covid-19 and various comorbidities at the same time is highly imprecise and may be intentional. We do not know exactly what the impact of Covid-19 alone is in terms of deaths after subtracting the negative health effects of various comorbidities. We do not know how many people who died from Covid-19 with co-morbidities would have died at the same time from co-morbidities but without Covid-19, i.e. if the SARS-CoV-2 coronavirus had never appeared. But this could be a significant proportion of these people, as they were also predominantly elderly.
Thank you very much,

JIT has demonstrated to be effective when it is well implemented. Before the pandemic, it was simple to stablish a weak JIT workflow with suppliers with barely no cooperation and minimum understanding of mutual workflows and value chains (especially with suppliers located in Asia). Creating long-term, mutually beneficial partnerships based on trust with all suppliers is at the heart of JIT and Toyota's basic principles; the pandemic has proven not everybody understood it. JIT is more than just a drastic cost reduction with carefully planned lead times for shipping raw materials.
JIT was, is and will still be relevant. In my opinion, JIT will adopt a new name in the upcoming years because business leadership will not trust an “old-fashioned methodology”. Most likely, it will be infused with a risk-based approach to implementation and supplier selection.

Some recent studies have documented COVID-19 being zoonotic. Online documents show china testing fish for the coronavirus. How ever, pets such as cats and dogs rarely show the signs of the disease even after infection, though there can still shed the virus to humans. To this effect, what preventive recommendation should be done against transmission of the virus between pets and humans. Is it possible fo the vaccine administered to humans also be administered to pets?
Relevant answer
Answer
Hello Exodus Akwa,
Pet animals were proven to be infected with SARS-CoV-2. In some cases, there are evidence of pets transmitting the disease to humans. Though it may be impractical/ difficult, avoiding contact with the confirmed infected pet is the only way out. In situations where the pet animals are asymptomatic, we cannot do anything. Some news of vaccine development for animals were reported from Russia, Finland (for ferrets) in the year 2021, however, their scientific publication is awaited. You can find more details in our recent review .

Hi there,
would like to learn more about appropriate material for the application of PPE in Epidemiology.
As all the material seems to be Polyethylene/Polypropylene, would love to learn, whether it is possible to use Polyamide material instead? Are the properties sufficient?
If Polyamide does the job, are normal Snowboarding and Fishing Overalls an alternative to the ordinary Hazmats?
Cherish your feedback.

Answer
The chemical nature of Polyamides, with potential reactive chemical groups, make it more susceptible to contamination than inert PE/PP in an Epidemiology environment. Physical properties are OK.

According to WHO Monkeypox is usually a self-limited disease with the symptoms lasting from 2 to 4 weeks, but severe cases can occur. Recently, the case fatality ratio has been around 3–6%. The association with transmission is more limited to cases related to homosexual patients, can it be a more limited spectrum indication? In this way, the public health advice for gay, bisexual and other men who have sex with men is the main point to be addressed? Or should we learn more from other Monkeybox outbreaks? Should the care applied to the COVID-19 pandemic be useful in this case, for example? It's something new (at least for the current variant) and one that has caused great distress especially after the traumatic worst phase of the COVID-19 pandemic. The WHO recommendations have been assertive and very coherent, therefore, in the progress of current studies we should have more answers, but the question for simple discussion remains in the air: Is Monkeypox outbreak that dangerous or is there not enough data yet?

One of my friends was accused of plagiarism; do you know why?
After about three months, his research paper was rejected because of plagiarism. When he checked the journal report, he found that his paper was accused of plagiarism with a 61% percentage. The reason is that his manuscript was previously uploaded as a preprint. It took him another two months to solve the problem and remove the manuscript from the database of the preprint.
So, in order to solve this type of issue, it may take several months of following up to remove the manuscript from the database of the preprint. Anyhow, If there were accusations of plagiarism, it is not well for any researcher's reputation, in any meaning.

Dear honorable researchers,
Preprints are defined as an author’s version of a research manuscript prior to formal peer review at a journal, which is deposited on a public server. ResearchGate (RG) said about "Preprints" an early-stage research.
Before answering this valuable question of Prof. Yashar Salami, please let me give my own opinion about preprint:
  • Why you let others know about your insights and methodologies before publication? You should avoid telling the other researchers about the details of anyone of your papers until it has been published and seeing your name by yourself. You may say that I am somewhat old-fashioned, but I have a different perspective for uploading any preprint anywhere before it has been published by your name. So, my advice is not to put your research anywhere until it is published.
  • Your manuscript may be copied and then published by others before you can do that. This stealing of your paper might be happening. So, you must wait until the paper is accepted and then published by that journal. Then, upload that research item on any platform you wish.
  • A journal may have automated plagiarism software to check the paper before admitting it to the reviewing process. There are chances that your paper can get a rejection at any point. Thus, to avoid this problem. Publish the preprint after you got the paper as "ACCEPTED".
Finally, for the coming future, do not upload any paper anywhere until it is published with your name. Even if it is a "preprint"! For the time being, If you had done something like that as a "preprint", for instance, I advise you to delete the preprint from any elsewhere and wait for two months before sending the paper to any journal.

Traditional construction of research knowledge in master and doctoral thesis programmes / modules mostly comes from close interactions between research students and their supervisors. Most master and doctoral theses have sharp research foci. Post-doctoral research publications based on the research works might take longer time to be completed after graduation, if students rely fully on their supervisors’ further guidance.
Luckily, some supportive or generous master or doctoral supervisors will help co-publish some journal papers with their research students, based on the thesis contents. Yet post-doctoral research works might not easily be offered under the same supervisors or the same universities. Without high-quality research publications, current young scholars ('baby-doctors') suffer badly from getting some post-doctoral scholarship or funded post-doctoral research projects, facing local and global keen competitions. Currently, mere doctoral degree cannot help much in most employment situations after graduation. Therefore, vacant post-doctoral teaching / researching job posts cannot be easily offered by universities or other higher education bodies in their own countries to young scholars after getting their doctoral degrees or even completing their postdoctoral studies in the slowly recovered local or international economic systems, especially under the violent attack of the COVID-19 pandemic.
To what extent can we (as university professors and lecturers) help remedy such situation, especially facing shortage of research fund? Any suggestions offered to our young scholars in local, international and global contexts?

  • More youth are struggling with their mental health and are seeking support online. Forty-five percent of individuals in the U.S. who took a screen in 2021 were youth ages 11-17 – 16% higher than the average in 2019.
  • The largest increases in the percentage of people scoring positive from 2019-2021 were on the parent and youth screens, indicating a large increase in the percentage of youth experiencing emotional, attentional, or behavioral difficulties during the pandemic. There were also significant increases in the percentage of people scoring at risk for PTSD, severe anxiety, and psychotic-like experiences from 2019-2021.
  • Across all screens, 76% (N=3,177,747) of users in the U.S. scored positive or with moderate to severe symptoms of a mental health condition in 2021. This was a 2% increase over the average in 2019 and a 1% increase over the percentage of individuals who screened at risk in 2020.
  • The number and percentage of people screening with moderate to severe symptoms of anxiety remain higher than rates prior to COVID-19, and are particularly severe for youth and multiracial screeners. In total, 850,267 people in the U.S. took an anxiety screen in 2021, which was 422% higher than the total number of anxiety screens taken in 2019 and 56% higher than the number taken in 2020.

The rapidly unfolding uncertainties caused by the COVID-19 pandemic to governments, business organisations, communities and individuals has necessitated the putting into place a set of economically mitigating measures to avert a deeper scarring to lives and livelihoods. Such measures often include furloughing employees, which means a temporary laying off of millions of employees in both developed and developing economies as a way to protect businesses from going under.
However, as some governments have started intimating that such an unprecedented move is time-restricted and that the acquired debt would have to be repaid from some other tax increases, promotion and recruitment freezes or austerity, a fundamental question needs to be asked within employment studies. Others may opine that longer-term and more sustainable strategies are needed as we are still uncertain as to how long this pandemic may last.
Therefore, the question for this discussion is 'should governments and businesses around the world furlough or not furlough staff?'

In the long run, businesses that did not furlough gained advantage.

However, because the Impact Factor is so sensitive to highly cited papers, some journal scores will reach stratospheric heights this year, only to collapse next year.

A total of 113 cases occurred in the study period (01 Feb to 25 Apr 21). Lower number of infections were observed among the fully vaccinated as compared to partially vaccinated and non-vaccinated. The overall vaccine effectiveness was found to be 88.6% (81.55–92.37) and 44.1% (4.55–67.3) in completely and partially vaccinated individuals respectively. Hazard Ratios for getting infected dropped significantly after 28 days of the second dose. The SAR in high risk contacts (HRCs) was found to be 4.25%, which was lower than SAR (20.6%) of pre-vaccination period.

Hi. I am validating one Covid 19 kit and covering different labs. I mainly used Quant studio 5 & 7 and Biorad CFX 1000 touch( qPCR machines).
My kit validation has passed from many labs but from one lab I am getting too much Invalids(even after several reruns with some variations). However, procedure and conditions are same in all labs. How to resolve this?
Only thing remaining to retest that Staff used "White plate" but they run the program for the "Transprent plate ". Does it make the result invalid / No IC?

Relevant answer
Answer
Many companies believe that WFH will become more common after the pandemic due to the fact that employers have already paid the fixed cost to set up remote work systems for their employees. Companies are now determining if operational costs could be dramatically decreased by reducing the required office space.

Whether the sub-variants of Omicron strain still remain infectious? Is it not uncommon for a natural virus?
To what extent, the immunity levels have been retained following the COVID19 vaccination doses?
Whether retaining the immunity levels would always require pandemic restrictions? Whether in the absence of pandemic restrictions – seasonal respiratory viruses could play a crucial role?
When will we have enough data on vaccine response – that would probably tell us on – whether – how much the sub-variants will be able to mitigate the protection from hospital admission?
To what extent, are we technically advanced in order to figure out the new mutations and even in such cases, how fast will we be able to react both medically as well as socially?
What is to be understood – when a triple-jabbed person (in the absence of co-morbidities) gets infected again?
Feasible to eliminate the virus completely from our system (body) – once we get infected with COVID19? To what extent, the ‘residual virus’ could infect – in the long run?

On 26 November 2021, WHO assigned the variant B.1.1.529 a variant of concern, named Omicron. This conclusion was based on the evidence that Omicron has several mutations that may have an impact on transmissibility or even severity. Moreover, it has been observed that there is not only the number mutations which are concerning , relatively large number of mutations are at the Receptor binding protein(RBD )binding interface to the receptor protein, the ACE2 as compared to other mutants like delta. The RBD on the spike protein is crucial for the initiation of infection, leading to the host cell entry. Further to this ,Omicron’s Spike protein has 26 amino acid mutations the insertion mutation (ins214EPE),that are distinct compared to other variants of concern. A recent and first laboratory study in South Africa in which 6 samples of patients having two doses of Pfizer vaccination with history of natural infection as well. The study revealed there was 41 fold reduction in neutralizing antibody binding as compared to delta in which 5 fold reduction in antibody was seen. This results in vaccine efficacy of only 22.5% against symptomatic infection, but the neutralizing antibody may be sufficient in preventing the severe disease.
