Abstract:
Objective To understand the pneumococcal vaccination status and its influencing factors among young and middle-aged populations, and provide reference for promoting pneumococcal vaccination.
Methods From May to August 2023, a multi-stage random cluster sampling method was used to select 5 928 residents aged 19 – 59 years old from Nanchang city in Jiangxi province, Changsha city in Hunan province, and Kunming city in Yunnan province for an online questionnaire survey on pneumococcal vaccination status.
Results Among the 4 895 young and middle-aged people finally included in the analysis, only 833 had received pneumococcal vaccine in the past 5 years, with a pneumococcal vaccine uptake rate of 17.02%; multivariate unconditional logistic regression analysis showed that the pneumococcal vaccine uptake rates were higher among those aged 45 – 59 years old, agriculture, forestry, animal husbandry and fishery production personnel, professional and technical personnel, smokers, those with general knowledge of pneumococcal diseases and vaccines, and those with general and good trust in pneumococcal vaccines, while the uptake rates were lower among those with high school/technical secondary school education or above and office clerks and related personnel; the top three reasons for pneumococcal vaccination among young and middle-aged people were disease prevention (75.87%), protecting family and colleagues (57.38%), and government and health administration recommending vaccination (43.22%), while the top three reasons for not receiving pneumococcal vaccine were worrying about adverse reactions after vaccination (42.22%), no time for vaccination (28.19%), and believing that the vaccine had limited effectiveness (25.11%), and the top three factors most likely to change vaccination willingness were free/discounted vaccines (46.63%), worrying about the impact of pneumonia infection on family and colleagues (46.53%), and government and health administration recommending vaccination (45.89%).
Conclusion The pneumococcal vaccine uptake rate among young and middle-aged populations was low, and age, education level, occupation, smoking status, knowledge of pneumococcal diseases and vaccines, and trust in vaccines was the main influencing factors for pneumococcal vaccination in this population. Comprehensive policy measures, especially the introduction of preferential policies related to pneumococcal vaccines, should be adopted to promote vaccination.
