Methods: A cross-sectional population-based study was conducted which included 1 258 participants. Blood samples were collected and questionnaires administered to obtain sociodemographic information and history of varicella and/or herpes zoster. Serum samples were assayed for VZV IgG antibodies using a commercial enzyme-linked immunosorbent assay kit. Results: Overall, the seroprevalence was 54.2%(95% CI= 51.5% 57.0%). Children below 1 year of age were seronegative, and only about 20.0% of children between 1 and 10 years of age were seropositive. Seropositivitiy increased with age and by the age of 40 years 74.3% were seropositive. Among women of childbearing age, the overall seroprevalence was about 62.0%(95% CI = 57.7%-66.1%) but was low 37.0% in the 15-19 age group. Conclusion: In this population, 45.8% lacked natural immunity against varicella. Of women of childbearing age, 39.9% lacked immunity and in the subgroup of women 15-19 years of age, 63.0% women lacked immunity. In light of the country's success with the control and high coverage of other vaccine preventable diseases and that the vaccine is available in the private sector, the inclusion of varicella vaccine in the national immunization program may be considered.展开更多

Methods: This descriptive study was performed in May 2009 in Kayseri, Turkey. 282 family physician accepted to fill a questionnaire about adult vaccination. Results: Most of the family physcians (83.0%) thought adult vaccination as a modality of protection and 66.7% wanted a vaccination scheme just like the one in childhood. Their own vaccination rate for Hepatitis B was 67.0% and 58.5% for influenza at any time. Only half of the physcians were vaccinated within the season for influenza. Only 9.2% of the doctors have stated that they ask questions to their patients about their vaccination status. When physcians were questioned about the vaccines they advise to their patients aged 65 and more;70.6% stated influenza and 39.7% stated pneumococcus. Conclusion: In spite of being in the risk group, family physicians have low vaccination coverage rates. Suggestion of the necessary vaccines to the risk groups or to their patients at risk is low as well.展开更多
