Coverage and influencing factors of influenza and pneumococcal vaccination among urban and rural residents 50 years old and over in Zhejiang province,2022-a cross-sectional survey
Objective To examine the coverage and influencing factors of influenza and pneumococcal vaccines among urban and rural residents aged ≥ 50 years in Zhejiang province for promoting the vaccination of the two vaccines in the population.Methods A face-to-face interview with a self-designed questionnaire was conducted during June of 2022 among 2 200 residents aged 50 years above recruited in 35 communities/villages of 7 districts/counties,Zhejiang province.The coverage of influenza and pneumococcal vaccination were statistically described and unconditional multivariate logistic regression model was used to analyze main influencing factors of influenza and pneumococcal vaccination.Results Of the 2 100 residents ultimately included in the analysis,776(36.95％)and 116(5.52％)reported having influenza vaccination in past one year and pneumococcal vaccination in past five years,respectively.The results of unconditional multivariate logistic regression analysis showed that the residents having the education of high school and above,with influenza vaccine-related awareness,being able to have free of charge vaccination,and ever receiving doctor's relevant recommendation were more likely to have influenza vaccination and that the residents being able to have pneumococcal vaccination free of charge and ever receiving doctor's relevant recommendation were more likely to have pneumococcal vaccination.The vaccinees of influenza and pneumococcal vaccine reported following similar vaccination motivations:receiving vaccination notification from community health centers(reported by 590[76.03％]and 85[73.28％]of the vaccinees),being promoted by suggestions of family members(400[51.55％]and 67[57.76％]),and self-intention to prevent the diseases(350[45.49％]and 51[43.97％]);while,the non-vaccinees of influenza and pneumococcal vaccine also reported similar reasons for not having the vaccinations,including without knowledge about influenza or pneumococcal vaccine(reported by 816[61.63％]and 1 334[63.52％]of the non-vaccinees),being worried about side effects of the vaccine(321[24.24％]and 442[22.28％]),and not perceiving vaccination necessity(296[22.36％]and 472[22.48％]).Conclusion The vaccination rate of influenza and pneumococcal vaccine are relatively low and mainly influenced by the accessibility of vaccinations free of charge and recommendation on the vaccinations from medical professionals among residents aged≥50 in Zhejiang province.
