Vaccination behavior and attitudes among adults changed in the early months of this year, with more people reporting they intended to get vaccinated, according to a new study.

Researchers looked at data from January 6 to March 29 of 2021. While one of the most encouraging findings was that the percentage of Americans who had received at least one vaccine dose or definitely intended to get the jab increased from 54.7% to 72.3%, Kimberly Nguyen, an assistant professor at Tufts University School of Medicine, still worries about the number of people who are still hesitant to get vaccinated.

According to the analysis, Non-Hispanic Black Americans and people who live in certain southeastern states are less likely to get vaccinated or intend to get vaccinated against COVID-19. Younger adults and people who are less educated or economically secure are also more reluctant to get vaccinated.

“It’s important that we target messages to continue to increase vaccine confidence and uptake in these populations,” Nguyen says.

Another bright spot was that while vaccination rates among non-Hispanic Black Americans were relatively low, this group showed the greatest increase in intent to get vaccinated—jumping more than 30%—over the study period.
