In the United States, COVID vaccination acceptance rates are determined by moral principles.

Despite the fact that COVID -19 vaccinations are safe and effective, and that they are widely available in the United States, many Americans are still hesitant to be vaccinated. In reality, COVID -19 vaccination rates vary greatly across the country: in some counties, virtually all people are vaccinated, while in others, only a minority of individuals are vaccinated. A new study conducted by USC researchers offers light on the assumptions that underpin these significant disparities in vaccination rates.

According to the study, which was published Wednesday in the journal American Psychologist, structural hurdles such as access to health care, historical under-vaccination, and political constraints explain why inhabitants of specific counties are less likely to get vaccinated against COVID -19. However, the study demonstrated that we must consider Americans' moral principles in order to interpret the huge discrepancies in COVID -19 immunization rates.

"If you look at a map of the proportion of vaccinations in each county in the United States, you find very large differences between counties, regions, and states," said Nils Karl Reimer, co-author of the study and a postdoctoral researcher at the University of Southern California's Dornsife College of Letters, Arts, and Sciences. "Our objective is to investigate whether disparities in political ideology correspond with variances in vaccination rates." We already know that conservatives and liberals have opposing ideals in the United States. 

Our study's purpose was to learn how regional disparities might help us explain discrepancies in immunization rates beyond structural obstacles, and that's exactly what we discovered. Beyond the established factors of political ideology and institutional constraints, moral values can explain these discrepancies."

The most crucial principles for vaccine acceptance COVID are fairness, loyalty, and purity.

According to moral foundations theory, there are five primary moral foundations: caring, fairness, loyalty, authority, and purity. The researchers calculated county-level moral values and conservatism using data from the website yourmorals.org, an online platform that collects a variety of psychological data. To account for characteristics not included in the research, these data were integrated with county-level vaccination rates from the Centers for Disease Control and Prevention, the U.S. COVID -19 Vaccine Coverage Index, and presidential election data.

According to the findings of the researchers' investigation, moral considerations like justice, loyalty, and purity affected vaccination rates at the county level, but not diligence or authority. Residents in districts where purity was valued were 0.8 times less likely to be vaccinated. Previous study has shown that "conservatives care more about contamination and items they deem nasty," according to the researchers.

Districts with more loyalty, on the other hand, were 1.14 times more likely to get vaccinated. Alternatively, if loyalty grew while other values remained constant, vaccination rates may rise by 3% nationally. Under comparable conditions, a high sense of justice was related with a 2% rise in vaccination rates.

The researchers compared the model's accuracy to two alternative models: one with only structural and demographic predictor factors, and another including party affiliation as an extra predictor variable. Neither model predicted county-level vaccination rates as precisely as the third, which included considered agreement with county-level moral concerns.

Vaccination opponents had better purity scores regardless of party membership.

According to the researchers, while the analysis mostly validated their expectations, some unexpected tendencies appeared. According to the authors, loyalty is often connected with conservative attitudes, which are associated with vaccine skepticism. However, when the four other moral foundations were controlled for, the study discovered that loyalty was related with greater vaccination rates.

"The findings of the loyalty research are rather surprising, given the conservative rhetoric regarding vaccine opponents. We show, however, that typical conservatives are not anti-vaccination "Morteza Dehghani, associate professor of psychology and computer science at USC Dornsife, is a co-author. "Anti-vaxxers are not always faithful, but they are always pure. This encompasses both conservatives and liberals who stress purity features, most commonly emphasizing on physical aspects of purity pollution ('My body is a temple, and it should not be defiled')."

"It's a sentiment you may find on both sides of the aisle," Reimer said, "and I believe that's the tremendous benefit of our method because it provides a more fine-grained examination." Conservatism is a collection of views that do not always make logical sense."

The findings might assist enhance COVID immunization rates by better targeting health communications.

While the new data corroborate the idea that county-level moral values influence COVID-19 immunization rates, the researchers cautioned policymakers to use these insights with care. For example, county-level results cannot be extended to smaller (cities, neighborhoods, people) or bigger (states) groups.

The findings provide policymakers and public health communicators with evidence to help them better reframe their pandemic-related public health messaging. The researchers propose appealing to feelings of loyalty by presenting vaccination as a patriotic responsibility to one's fellow citizens. To better appeal to vaccination doubters in high-purity settings, they recommend messages highlighting the vaccine's potential to protect against contaminating illness.

"I think a lot of individuals who are dubious of vaccination may conceive of it as a foreign substance brought into your body," said Reimer. "This sounds terrifying, like something you wouldn't want to put in your body, but putting it in terms of the normal immune system reaction may sway some skeptics. These are, of course, only hypotheses pending future research, but our findings potentially hint to public health messages that could be evaluated."
