Vaccine hesitancy, its resurgence, and pervasiveness continue to generate new perceptions of disease, cure, and health management. Owing to this light, the paper identified the social acceptability of vaccines as a health-seeking behaviour, capturing the attitudinal differences based on gender, age, occupation, economic class, and dependency level. This study was conducted in urban settlements in Delhi NCT and NCR, India, among young adults (15-24 years old) during pre- and post-vaccination periods. ‘Hesitancy’ was interpreted into- Vaccine Eager Group, Vaccine Ambiguous Group, and Vaccine Hesitant Group showing a continuum between the three. This supports the argument of the paper that comprehension of vaccine acceptability was affected by the subjectivity of people for which the attitudes can transition from acceptance to hesitancy or vice versa. The study also points to participants’ multiple reasons for fear constructions through the decision-making process, influenced by two dimensions- Preference of Health Model and Perception of Life. And how vaccine hesitancy can be analysed as a social phenomenon when inferred collectively. In addition, the impact of infodemics and the digital-ness of the pandemic has been taken into account to show the presence of dominant voices that help individuals decide. Therefore, highlighting how people’s multiple identities and cognition both influence the construction of meaning around vaccines for large-scale delay/acceptance in vaccine consumption. This study is based on secondary and primary data. It showed willingness towards the COVID-19 vaccine. It can further be expanded to create methodological frameworks that can be applied to disaster management by creating specific tools for measuring hesitancy before an intervention. Secondly, it prioritizes the reflection of who understands the pandemic information landscape better and whose voice can dominate in building perception.
