Role of Vaccine Hesitancy, eHealth Literacy, and Vaccine Literacy in Young Adults' COVID-19 Vaccine Uptake Intention in a Lower-Middle-Income Country

Various control measures, including vaccination, have been taken to flatten the COVID-19 epidemic curve across the globe. However, in Bangladesh, many young adults, considered the asymptomatic transmitter of the disease, are waiting to get their first shot. Therefore, the potential predictors of the young adults' vaccine uptake intention are significant to ensure their maximum vaccination when available to them. This study examined how vaccine hesitancy, eHealth literacy, and vaccine literacy are associated with young adults' COVID-19 vaccine uptake intention in a lower-middle-income country. A total of 343 young adults participated in the study. Using ordinary least square and probit estimation, we examined the effect of the explanatory variables of interest on vaccine uptake intention. Vaccine hesitancy emerged as the strongest predictor of vaccine uptake intention. eHealth literacy shared a positive association with vaccine uptake intention, while vaccine literacy had no significant association. To make young adults feel more confident about the vaccine, transmitting the latest vaccine safety updates through authentic channels is essential. The government can aim to enhance the eHealth literacy of young adults as an increased level of eHealth literacy will enable young adults to extract reliable health-related information more efficiently than ever.

Automated summary

The study found that vaccine hesitancy is the most important factor affecting young adults' willingness to get the COVID-19 vaccine, while eHealth literacy is positively associated with vaccine uptake intention, and vaccine literacy is not significantly associated. To boost young adults' confidence in vaccines, it is crucial to communicate the latest vaccine safety updates through authentic channels.
