Confidence in vaccines is lower post-pandemic across all demographic groups.
Vaccine confidence has declined significantly since the start of the pandemic, according to a study from the University of Portsmouth. Researchers used anonymous surveys in the winters of 2019 and 2022 to examine attitudes toward vaccinations and that factors that might lead to hesitancy and refusal.
The results from more than 1,000 adults show the post-pandemic group was considerably less confident in vaccines than the pre-pandemic group. The results were published in the medical journal Vaccine.
Researchers found that nearly one in four participants reported a fall in confidence since 2020, and this occurred regardless of age, gender, religion, education, and ethnicity.
“While vaccine hesitancy is not a new phenomenon, COVID-19 vaccines have been met with particular hostility despite the overwhelming scientific evidence of their safety and effectiveness,” says Alessandro Siani, associate head of the School of Biological Sciences at the University of Portsmouth, in a statement. “This isn’t just among conspiracy theorists though, but also those who don’t consider themselves ‘anti-vaxxers’ and had supported other vaccination campaigns in the past.”
Participants were asked how much they agreed with statements including:
In both surveys participants who held religious beliefs were significantly more vaccine-hesitant than atheist and agnostic ones, and individuals from Black and Asian backgrounds were more hesitant than those belonging to White ethnicities. However, gender showed no association with vaccine confidence.
While these overall trends remained largely similar between the two surveys, some noteworthy changes were observed in the post-pandemic survey, according to researchers. For example, the analysis revealed that while in 2019 middle-aged participants were considerably more apprehensive about getting vaccinated than younger groups , this was not the case in the 2022 survey.
“This could be because COVID-19 infections notoriously lead to more severe outcomes in older patients,” said Siani. “Young people who are infected rarely experience severe symptoms that lead to hospitalization and death, so it’s possible that many have become complacent and don’t feel the need to get vaccinated. On the other hand, older people may have been more wary of the consequences of the infection, and more appreciative of the protection offered by the vaccine.”
While providing precious insight into how the pandemic affected the public perspectives on vaccinations, the study is not without limitations. The original survey was designed as a standalone piece of research, so a different group of people had to be sampled in 2022. This resulted in a cross-sectional study as opposed to a longitudinal one.
“However, the study is consistent with other observations suggesting that vaccine confidence may be yet another victim of the COVID-19 pandemic,” said Siani.
