ABSTRACT

Objectives Adult immunisation has recently emerged as an area of emphasis in research and policy. Increasing life expectancy, outbreaks like COVID-19, and the endemic nature of diseases like dengue, malaria have underscored its importance. Therefore, this study was carried out to assess hesitancy and the factors influencing the uptake of vaccines in adults. Methods A descriptive cross-sectional study was conducted among the medical students and doctors affiliated to a medical college and tertiary care hospital in Delhi, India and their immediate family members in January 2021. Online data collection was done using the Google Form platforms. Data on awareness and perceptions regarding adult vaccination and immunisation status of participants was collected. The dataset was exported in the Microsoft Excel format and analysed with IBM SPSS Version 25 (Armonk, NY: IBM Corp). Results A total of 461 adults responded to the survey. The most common reasons for vaccine hesitancy were fear of side effects (51.41%), lack of awareness of vaccines (49.46%), and the lack of national guidelines on adult vaccination (32.97%). Hesitancy for vaccines among those who were informed by healthcare workers of vaccine availability was highest for zoster vaccine (97.80%) and least for tetanus toxoid (57.62%). Significant hesitancy was also observed for pneumococcal, human papillomavirus, influenza and varicella vaccines. Conclusions Reduced vaccine uptake due to vaccine hesitancy in adulthood is a major health concern. Framing national guidelines for adult vaccination in India and awareness generation to create a public demand for adult vaccination warrants prioritization.

ABSTRACT

Background Adult immunization has recently emerged as an area of emphasis in research and policy. Increasing life expectancy, outbreaks like COVID-19, and the endemic nature of diseases like dengue, malaria have underscored its importance. Therefore, this study was carried out with the aim to assess hesitancy and factors influencing the uptake of vaccines in adults. Methods An online cross-sectional study was conducted among adults (age more than 20 years). Data collection was done by convenience sampling in January 2021. Information on awareness and perceptions regarding adult vaccination and immunization status of participants was collected. Data analysis was done using SPSS version 21. Results A total of 461 adults responded to the survey. Among those who had never received any vaccine in adulthood (n = 158), the reasons were lack of recommendation by healthcare providers (38.6%), lack of knowledge of vaccines (15.8%) and fear of adverse effects following vaccination (7.6%). Hesitancy for vaccines among those who were informed by healthcare workers was as follows: shingles (97.8%), human papillomavirus (92.1%), pneumococcal (91.1%), influenza (79.7%), varicella (79.4%) and tetanus (57.6%). Conclusions Reduced vaccine uptake due to vaccine hesitancy in adulthood is a major health concern. Hesitancy was highest for the shingles vaccine and least for the tetanus vaccine. Key messages Coverage of adult vaccination can be improved by formulating national guidelines and encouraging healthcare providers to raise awareness. In-depth qualitative studies are needed to understand the perception of adults towards vaccination.
