Abstract

Background: Adult vaccination is a crucial yet underutilized component of public health, especially in rural areas where access to healthcare services is limited. Inadequate awareness regarding adult immunization ad-versely impacts individual health, healthcare systems, and economic productivity. Objective: To assess the knowledge, attitude, and behavior related to adult vaccination among rural population, Tamil Nadu. Methods: A cross-sectional study conducted among 260 healthy adults (18 to 80 years) in rural Chengalpattu District, Tamil Nadu, used simple random sampling method. Data were collected using a pre-tested, struc-tured, and validated self-administered questionnaire, focusing on adult vaccination knowledge, attitude, and behavior. Data analysis was performed using IBM SPSS version 25. Results: Among 260 participants, 41.9% were aged 18-40 years. Covid-19 vaccine had the highest knowledge level (77%). Logistic Regression showed literacy (AOR:4.95) and socioeconomic status (AOR:2.43) significantly associated with knowledge. Likewise, literacy (AOR:3.65) and socioeconomic status (AOR:3.53) were significantly associated with attitude towards adult vaccination (p <0.05). Conclusion: The study findings underscore education, occupation, and socioeconomic status have a significant impact on adult vaccination acceptance. Addressing barriers to immunization through awareness cam-paigns and policy interventions is critical to improving adult vaccine uptake in rural populations.
