COVID-19 Vaccine Acceptance and Its Determinants in the General Population of Delhi, India: A State Level Cross-Sectional Survey

Abstract

Objective: To ascertain the COVID-19 vaccination acceptance and the factors contributing to vaccine hesitancy and vaccine confidence in the adult population, and the intention for vaccination of their children.Methods: This cross-sectional analysis reports the ancillary results of a population-based SARS-CoV-2 serosurvey conducted in Delhi, India, from September 24 to October 14, 2021. Data were collected from 20312 adult participants through a multistage sampling method from all the 274 wards in the 11 districts of the national capital territory region.Results: We enrolled 12093 (59.3%) females and 8219 (40.5%) male participants with mean (SD) age of 40.3 (14.6) years. The vaccine acceptance rate in the participants was 67.7% (95% CI 67.1, 68.4), with 6031 (43.8%) having received one dose and 7727 (56.2%) having received two vaccine doses. On adjusted analysis, lack of vaccine acceptance was independently associated with female gender aOR 1.

Acceptance of COVID-19 Vaccines in India: A Systematic Review and Meta-Analysis

“…Factors positively influencing the acceptance of COVID-19 vaccination are extensive public knowledge about COVID-19, where 70% of the population that had better knowledge about the vaccines [ 35 ], and a good attitude towards it. The likelihood that a participant might acknowledge vaccine acceptance increased with their perception of their risk of suffering from COVID-19, their belief that the vaccine would protect them from COVID-19, and their belief that the vaccine would not cause any negative adverse consequences.…”

“…In the study by Sharma P et al, among the population residing in Delhi, most of them were hesitant about the acceptance of the COVID-19 vaccine. The main causes were a lack of knowledge about COVID-19 immunisations and concerns about vaccine efficacy and long-term efficacy [ 35 ]. In their survey, Kusuma Y. et al discovered that the elderly generation has a lower psychological vulnerability to acquiring COVID-19, a lower perceived threat of COVID-19, poor self-defense against COVID-19, and a lack of awareness and non-use of the Aarogya SetuApp as major determinants of vaccine reluctance [ 36 ].…”

Media Reporting Relating to COVID-19 Vaccination as a Driver of Vaccine Hesitancy Prior to the Second Wave of the COVID-19 Pandemic in India: A Content Analysis of Newspaper and Digital Media Reports

“…Failure to vaccinate nearly 85-90% of the vulnerable adult population was a major factor driving the second wave of the COVID-19 pandemic in India for it is well-established that vaccination with most of the available COVID-19 vaccines significantly reduces the odds of severe disease, hospitalization, and death [2][3][4]. Vaccine hesitancy referring to the delay in the acceptance or refusal of vaccines despite their availability was a significant reason for the low uptake of COVID-19 vaccines in India prior to the Delta wave especially among eligible health workers, comorbid, and older people [5,6].…”

Beliefs and Barriers to COVID-19 Vaccine Acceptance in Three Countries with Different Human Development Index (HDI) Scores: A Comparative Study

“…The researchers, who conducted the surveys in 2020–21, found that vaccine acceptance may vary over time according to what information the general public is exposed to at a particular moment. 13 , 14 Many studies have investigated COVID-19 vaccine acceptance in individual countries, but to our knowledge no study has compared vaccine acceptance among the general population of countries based on their HDI score. Therefore, this study aimed to compare beliefs about and barriers to COVID-19 vaccine acceptance in countries with varied HDI scores.…”
