This descriptive study was performed in 2009 May-July, in 6 public health centres (PHC) in the province centre of Kayseri, by way of a questionnaire. 998 adults from the population of an area covered by 34 family practitioners, working under six public health care centres, in the province centre of Kayseri, were asked to fill a questionnaire. Chi-square test was used in the statistical analysis and p < 0.05 was accepted as significant. The mean age of the participants was 37.4 ± 14.1 and 56.7% were female. 75.8% of the individuals knew that adults had to be vaccinated and 55.3% that influenza vaccination had to be done every year. 97.9% of the participants were aware of influenza vaccinLation, and the rate of vaccination was 7.8%, 97.8% knew tetanus vaccination, the awareness rate of hepatitis B vaccination was 84.4%, and vaccination rate 25.6%, Human Papilloma Virus (HPV) was known by 44.4%, vaccination rate in women was 1.1%, pneumococcus vaccination was known by 19.8% and vaccination rate was 0.4%. 22.0% of the individuals 65 years old and above had got an influenza vaccination while non-had got a pneumococcus vaccination. It is found that the tetanus, influenza, and hepatitis vaccinations were highly known, whereas, HPV and pneumococcus vaccinations were not, and that the number of individuals stating that they had been vaccinated was quite low.展开更多
