... For example, it has been reported that, today, vaccines are not very effective against infection and transmission of the Omicron variant, even at the peak of the immune response after boosting. Thus, it is likely that the level of neutralizing antibodies needed to protect against infection with the highly transmissible Omicron variant should be much higher than that required to protect against previous variants [15,49]. ...

... Recently, a cohort study has explored viral load dynamics during the prevalence of the Gamma variant under the influence of CoronaVac and Covishield vaccines, suggesting that these vaccines may not significantly decrease SARS-CoV-2 viral load compared to unvaccinated individuals [21]. Similarly, research on the Delta variant has found even higher SARS-CoV-2 viral loads in unvaccinated individuals compared to those vaccinated with CoronaVac or Covishield [21,22,[35][36][37]. Studies involving other vaccines like Comirnaty (Pfizer-BioNTech) and Spikevax (Moderna) have also failed to identify a significant impact on viral load in Delta variant infections [38]. ...

... Their diaries revealed impacts on social intimacy, social events, and socioemotional distress. While some research has suggested college students were careless and sometimes brazen in the counter-SD risks they took (Martinez, 2018;Rosenblum et al., 2022), and other research shows that a variety of factors can weaken compliance (Rahimi-Feyzabad et al., 2023), our diaries portrayed feelings of vulnerability and dutiful compliance to SD protocols. Our observation that fear and joy were proportionately the most common emotions associated their passages discussing SD is a testament to the emotional turmoil students were experiencing. ...

... Document analysis is one of the analytical methods in qualitative research, which reviews and evaluates various kinds of documents (print and electronic) to gain understanding and empirical knowledge Morgan, (2022). Document analysis was conducted by analyzing CP (Capaian Pembelajaran), ATP (Alur Tujuan Pembelajaran), and textbooks used by students. ...

... Numerous deaths linked to varicella are caused by the typical complications, which mostly affect adults, newborns, and immune-compromised people. Varicella subclinical cases are rare [25,26] . ...

... ; month seroprevalence values were likely mostly due to natural infection, it is expected that the vaccine rollout played a significant role in the increase in seropositivity at 12 months. While smaller serosurveys have identified significant trends among small populations, these trends may not be applicable in larger populations (35,36). In this study we utilized a large number of samples from the United States and additionally screened for antibodies against a wide number of antigens to allow for identification of trends in seroprevalence for several different antigens to overcome some of the limitations of smaller serosurveys. ...

... Year-round acute respiratory illness (ARI) surveillance began in 2015. [10][11][12][13] The study conducted active surveillance for ARIs among cohort enrollees during the COVID-19 pandemic once new strategies to collect specimens were implemented according to SARS-CoV-2 transmissioncontrol restrictions. 14 Here, we report changes to the circulation of respiratory viruses throughout multiple early waves of the pandemic in a cohort of households reporting high levels of COVID-19 mitigation practices with repeated serosurveys for the acquisition of SARS-CoV-2 antibodies. ...

... Because of the limitations on movement around the university, students are likely to spend more time in their halls of residence each day. According to studies, students who share a bedroom are twice as likely to be infected as those who live alone [57]. In addition, many students find distance learning physically and psychologically stressful and are eager to return to school but reluctant to take the risk [58]. ...

... Furthermore, IHEs could drive transmission to surrounding communities, which can be more susceptible to severe disease than IHE populations [1][2][3][4] . Many IHEs reported outbreaks of COVID-19 shortly after the 2020-2021 academic year began 3,[5][6][7][8][9] . Cases also increased rapidly during this time in US counties that had IHEs 1,3,10 , although increases were less severe in counties with IHEs that implemented mitigation measures including online instruction and SARS-CoV-2 surveillance testing 11 . ...

... To determine if nasal samples have an equivalent detection ability to nasopharyngeal samples with RAT, we also included 115 papers that employ nasopharyngeal swabs (Table S2). Among the 49 studies on nasal swabs containing 79,073 samples [2][3][4]6,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], all of them were published between 2021 and 2022, and twenty-one studies were conducted in the USA [12,14,15,18,21,22,[25][26][27][32][33][34][35]39,44,45,[47][48][49][50][51]. Thirty-four studies described the patients' symptom status [2,4,6,11,12,14,16,[18][19][20][21][22][26][27][28][29][30][31][32][34][35][36][37][38][39][40][42][43][44][46][47][48]50,51]. ...
