The number of daily vaccinations in the U.S. has steadily increased since early June with the rise of the Delta variant.

FDA’s decision to approve the Pfizer-BioNTech vaccine, the first to win that status, on August 23 appears to have hastened vaccinations further. Vaccinations have increased by 17% after that decision.

In particular, the approval appears to have fueled an uptick in the number of people obtaining the first dose of vaccine.

According to an Axios/Ipsos survey, the approval has led to a decrease in vaccine hesitancy, with two out of 10 Americans stating they were unlikely to pursue vaccination, according to an Axios/Ipsos survey. Earlier in the year, the number of vaccine-hesitant Americans was twice as high.

A growing number of U.S. companies are supporting vaccine mandates, with more than half of U.S. companies planning on requiring vaccination by the end of the year, according to Reuters.

A significant number of Americans, however, continue to oppose vaccination. A total of 14% said they were not at all likely to get vaccinated. For the sake of comparison, 29% of Americans were firmly against vaccination on August 21–24, 2020, according to the Axios/Ipsos survey.
