The importance of mothers: The social transmission of COVID-19 vaccination attitudes and uptake

The global fight against the COVID-19 pandemic has underscored the critical importance of widespread vaccination to mitigate the impact of the virus on public health. The current study aimed to investigate which social influences might be most important for predicting attitudes towards COVID-19 vaccination and vaccine uptake among young students in the UK. We focused on the cultural evolution and social transmission aspects, i.e., parent-to-child versus peer-to-peer, of attitudes and vaccine uptake during the COVID-19 pandemic. A sample of 192 UK students (aged 18 to 35 years old) filled in an online survey including measures for attitudes towards COVID-19 vaccination and vaccine uptake and/or intention, age, and gender. Participants were also asked about their mothers, fathers, and best friends attitudes towards COVID-19 vaccination and vaccine uptake. Finally, they provided a subjective measure of the quality relationship with their parents. Overall, our results suggest that both parents and very close friends are important agents in understanding the students attitudes towards COVID-19 vaccination and vaccine uptake. More specifically, our findings suggest the mothers vaccine uptake as the most salient predictor of students attitudes towards COVID-19 vaccination and vaccine uptake, particularly when the students disclose having a positive relationship with their parents. In cases where students experience negative relationship with their parents, the best friends vaccine uptake may supersede the mothers influence. Despite these nuances, a general trend emerges from our data suggesting that vaccine uptake could be primarily guided by vertical transmission (i.e., parent to child). Our results have the potential to influence public health strategies, communication campaigns, and targeted interventions to enhance vaccination uptake. Identifying key social predictors can enable policymakers and health authorities to tailor vaccination promotion efforts towards mothers and peers vaccine uptake to increase overall positive attitudes and vaccine uptake among young people.
