    ABSTRACT: Abstract Objectives: To investigate the coverage of the 23-valent pneumococcal polysaccharide vaccine (23-PPV) in the Chinese urban elderly population and to understand the attitudes, knowledge and beliefs of this population toward the 23-PPV vaccination. Methods: A cross-sectional approach was employed to survey the willingness of this population to receive the 23-PPV vaccination. Two thousand nine hundred twenty-six subjects over the age of 60 years were enrolled via a multi-stage random sampling method from the urban community population in Hangzhou, China. The relationships between the variables and the willingness to receive the 23-PPV vaccination were computed as odds ratios (ORs) by multivariate analysis. Results Of the participants, 21.77% were willing to undergo 23-PPV vaccination, and 61.65% of the subjects agreed that pneumonia is a serious disease among elderly people. The rate of reasonable perceptions about vaccination, including the perception about vaccine efficacy and safety, among the subjects was below 50%. Only 1.23% of subjects had been vaccinated with 23-PPV, and a similarly low rate was observed for the seasonal influenza vaccine (4.17%). The factors that were independently related to the willingness to receive the 23-PPV vaccine included consensus with the hazards of pneumonia (OR = 1.67, 95% CI: 1.28-2.17), the safety of vaccination (OR = 2.00, 95% CI: 1.54-2.59), advice about the 23-PPV vaccination from family members (OR = 2.37, 95% CI: 1.39-4.40), influenza vaccination history (OR = 2.57, 95% CI: 1.66-3.98) and pneumococcal vaccination history (OR = 7.48, 95% CI: 2.4-22.92). Conclusion: The administration of the 23-PPV vaccine among the urban elderly population is not optimistic in China. Emphasis on persuasion from families and the improvement of knowledge about vaccination might encourage elderly people to get the 23-PPV vaccination. Suggestions from physicians did not affect the participants' willingness to get the 23-PPV vaccination in multivariate analysis, but elderly people typically visited the Community Health Center (CHC) in their residential districts, and thus, systematic encouragement from healthcare physicians might be the key to increasing 23-PPV vaccination.

    ABSTRACT: Objective: Following the national proclaim of Measles Elimination 2012, plenty of activities for controlling the incidence had practiced in Hangzhou. However, the incidence did not decrease to low degree and remained perform as gap to the elimination target. The present study aimed to describe the epidemiological characteristics of measles, and proposed reasonable method to the target in Hangzhou. Method: Cases were collected by the National Notifiable Diseases Surveillance System (NNDSS) from 2004 to 2011. The descriptive epidemiology was employed to analyze characteristics of measles. Results: A total of 4712 confirmed cases were enrolled by the NNDSS with 7.87 per 100,000 people of incidence rate on average from 2004 to 2011. Individuals lived urban districts had higher risk of measles than counties. Infants aged<1 year observed the highest incidence rate with 239.35/100,000, and the age-specific incidence rate declined along with aged-group but reversed at adults. 52.20% of cases were floating cases and the measles vaccination was significantly different from the local cases (χ ( 2) =51.65,p< 0.001). February to June was the epidemic period for measles incidence with 81.88% of cases reported in cluster. Conclusion: The descriptive characteristics of measles suggested that factors included infant and adult individual, floating population, and living urban area might be relate to the elimination target. More efforts were need to ensure susceptible population had accepted qualified measles vaccination.

    ABSTRACT: To know the attitude toward seasonal influenza vaccination among healthcare worker (HCWs) and general community population (GCP s) in the post-pandemic influenza A/H1N1 period. A total of 489 participants including 126 HCWs and 363 GCP s completed the investigation. 33.33% individuals (34.92% HCWs vs. 32.78% GCP s, p > 0.05) intended to accept the seasonal influenza vaccination after pandemic influenza A/H1N1. Individuals received seasonal influenza vaccination in the prior 3 y and monovalent A/H1N1 vaccination in 2009 were aggressive to vaccinate seasonal influenza vaccine with adjusted OR = 5.21 (3.20 ~ 8.49) and 1.97 (1.18 ~ 3.30). According to the results of multivariable logistic regression model, the safety not efficacy of influenza vaccine was the significant factor for acceptability of seasonal influenza vaccination (OR: 3.11, 95% CI: 1.76 ~ 5.50). The positive attitude of serious degree of influenza A/H1N1 and occupational factor were also associated with the willingness of seasonal influenza vaccination and the adjusted ORs were 2.09 (1.14 ~ 3.83) and 1.62 (1.00 ~ 2.64). We conducted a cross-sectional investigation in the beginning of seasonal influenza vaccination between 2010 and 2011, employed logistic regression analysis to compute the relationship between the willingness of seasonal influenza vaccination and variables after pandemic influenza A/H1N1. Participants showed low acceptability of seasonal influenza vaccination after pandemic influenza A/ H1N1. Need educational program concerning the advantages of vaccine, comprehensible information about possible adverse effects and the hazards of seasonal influenza disease, which might motivate individuals to accept seasonal influenza vaccination.
