[Analysis of herpes zoster vaccination intention and related factors among ≥50-year-old patients with multiple chronic diseases in Zhejiang Province].

This study aimed to analyze the intention and related factors of herpes zoster vaccination among ≥50-year-old patients with multiple chronic diseases in Zhejiang Province. A convenience sampling method was used to conduct a questionnaire survey among ≥50-year-old patients with multiple chronic diseases in Zhejiang Province from March to May 2024. A multinomial logistic regression was used to analyze the related factors of vaccination willingness. The results showed that among the 2 531 study subjects, 40.85% were willing to receive the herpes zoster vaccine, 26.75% were unwilling, and 32.39% were indifferent. A multinomial logistic regression revealed that the history of influenza vaccination (OR=1.71, 95%CI:1.36-2.16), history of pneumonia vaccination (OR=1.39, 95%CI:1.05-1.85), doctors' recommendations for vaccination (OR=3.32, 95%CI:2.58-4.26), knowledge of herpes zoster disease (OR=1.43, 95%CI:1.10-1.86), considering herpes zoster as contagious diseases (OR=1.75, 95%CI:1.33-2.30), believing that vaccines could prevent herpes zoster (OR=1.48, 95%CI:1.14-1.93), and believing that middle-aged and elderly people could more likely to get herpes zoster (OR=1.30, 95%CI:1.01-1.67) were more willingness to receive herpes zoster vaccine. The reasons for unwillingness to receive the herpes zoster vaccine were never having heard of this vaccine (57.01%),"I did not think I would get it/I did not feel it was necessary"(25.95%), and "it was too expensive to afford"(16.27%). Television, doctors, and family members were the main ways to obtain knowledge about the herpes zoster vaccine. Compared with other age groups, those aged 80 years and older were more likely to receive vaccine information from family members (59.75%). People in the age group of 50 to 59 years old gradually tended to obtain vaccine information through WeChat (55.51%) and TikTok (42.02%). In summary, the herpes zoster vaccination intention is low among ≥50-year-old patients with multiple chronic diseases in Zhejiang Province. The vaccination history, recommendations from doctors, knowledge of the disease and its contagiousness, and awareness of the vaccine are related factors for the willingness of patients with multiple chronic diseases to receive this vaccine.
