A research involving hypothetical COVID-19 vaccines means that vaccine effectiveness and danger of unintended effects considerably affect folks’s preferences for one vaccine over one other, and that variations between vaccines could matter much less to those that are vaccine hesitant. Sabrina Stöckli of the College of Bern and the College of Zurich, Switzerland, and colleagues current these findings within the open-access journal PLOS ONE on Might 4, 2022.
COVID-19 vaccines are easing the unfold and severity of the illness in lots of elements of the world. Regardless of their security and effectiveness, some people who find themselves eligible to get vaccinated are hesitant to take action. A deeper understanding of the elements that affect perceptions of vaccines may assist inform efforts to deal with vaccine hesitancy and preserve headway towards the pandemic.
To research vaccine preferences, Stöckli and colleagues introduced greater than 5,000 folks from France, Germany, and Sweden with pairs of hypothetical vaccines that diverse in a number of attributes, together with effectiveness, nation of origin, and price. The individuals rated how probably they might be to decide on to obtain every vaccine and chosen their most popular vaccine from every pair. Additionally they answered questions on their danger tolerance and their attitudes in direction of vaccines.
Statistical evaluation of the outcomes confirmed that the attributes with the largest affect on hypothetical vaccine choice have been effectiveness and prevalence of unintended effects. Individuals have been additionally much less more likely to favor vaccines from China or Russia and extra more likely to favor mRNA vaccines and those who price much less.
Nonetheless, individuals who displayed higher vaccine hesitancy confirmed much less distinction between totally different attributes of their vaccine preferences. The researchers say these findings spotlight the necessity to account for folks’s particular person variations when contemplating vaccine preferences.
As a result of the attributes of those hypothetical vaccines don’t essentially replicate traits of precise COVID-19 vaccines, the real-world implications of this research could also be restricted.
Nonetheless, whereas extra analysis is required, the researchers conclude that public well being messaging ought to search to make clear the attributes of various vaccines, however that such efforts usually are not more likely to enhance vaccination charges amongst people who find themselves essentially the most vaccine hesitant. As a substitute, messages for this inhabitants may give attention to altering attitudes in direction of vaccines.
The authors add: “In step with different research, we present that folks a lot most popular to obtain vaccines that have been proven to supply a strong degree of safety towards COVID-19, with minimal unintended effects, whereas different variations between vaccines had minimal influence on uptake. Nonetheless, we present that these elements mattered way more for individuals who have been already open to vaccinations typically, whereas vaccine hesitant people have been a lot much less more likely to settle for a COVID vaccine, no matter how efficient and protected it was.”
