(Reuters). Thousands of Americans have received COVID-19 boost shots at a record rate after the Biden administration increased eligibility. However, officials from the health department were worried about the possibility of rising infection rates ahead of the Christmas holiday season.

According to the U.S. Centers for Disease Control and Prevention data, 37.5 million Americans had been given a booster shot as of Tuesday.

“It is a start,” Dr. William Schaffner from Vanderbilt University School of Medicine said. He also stated that boosters are important to personal protection and not for reducing the spread of disease.

I hope for more. He stated that booster uptake would be greatly increased if it were done quickly.

U.S. regulators extended eligibility for vaccine booster shots across all adults. This was in light of a rising number of infections among Americans, which has led to millions more Americans being eligible.

People 65+ and people at risk for infection from underlying medical conditions and employment were previously eligible.

CDC data showed that over six million people were vaccinated with one of the approved COVID-19 vaccinations. It was the most weekly dose since boosters became legal in 1993. The number is also up by more than 15% from last week.

More than 130 million Americans are fully vaccinated and eligible to receive the shot, provided they have received the Pfizer/BioNTech dose at least six months ago. Moderna (NASDAQ:) vaccines or two months after receiving Johnson & Johnson (NYSE:)’s one-dose vaccine.

A quarter have had boosters. Experts believe that the eligibility criteria for booster shots were complicated, which may have discouraged some people from getting them.

There is a lot more reason to support boosters today than there was when the White House introduced the idea (in August). “They did send mixed signals,” Dr. William Moss of the Johns Hopkins Bloomberg School of Public Health, said. “We’re in a better spot now.”

WANTING IMMUNITY

For weeks, top officials such as Dr. Anthony Fauci and Rochelle Walensky, Director of the CDC, have been urging Americans to get additional protection before they travel or gather with family and friends for U.S. Thanksgiving.

Following two months of decreasing infections, the United States reports daily rises in infection rates over the last two weeks. These are due to an easier-to-transmit Delta strain of the virus as well as people staying indoors because it is colder.

“We’d like to get as many people who were originally vaccinated with the first regimen boosted,” Fauci said https://www.reuters.com/business/healthcare-pharmaceuticals/fauci-says-vast-majority-vaccinated-americans-should-get-covid-19-booster-2021-11-23 on Tuesday in an interview for the upcoming Reuters Next conference.

According to him, the COVID-19 booster shots should be given to the vast majority of Americans that have received their initial inoculation. They provide “substantial” additional protection.

Because of the data showing that immunity from the first shot decreases with time, regulators supported the addition doses. Study data has demonstrated that booster doses have a higher average level of neutralizing antibody than those given at the beginning. Pfizer They can reduce infection rates by as much as 80% (NYSE:

Scientists believe that boosters should not be used for healthy adults. They argue that vaccines of the unvaccinated should take precedence.

The World Health Organization (WHO), has warned against boosters being made available to countries until the primary dose has been received by more people.

Hans Kluge (WHO’s European Regional Director), urged Europeans Tuesday to take booster doses in case of rising cases. If nothing is done, the WHO warned that there may be another 700,000.
