FDA Authorizes 2nd Booster: What To Know In CT

CONNECTICUT — People 50 and older and anyone who is immunocompromised in Connecticut may get a second COVID-19 booster shot, the Food and Drug Administration announced Tuesday.

Those eligible can get either the Pfizer or Moderna booster at least four months after getting the first booster from either vaccine manufacturer. For those 12 and older who are immunocompromised, the FDA authorized a second Pfizer booster at least four months after the initial booster. The Moderna booster may be given to those 18 and older who are immunocompromised after the same period.

In its announcement, the FDA cited evidence of waning immunity in older and immunocompromised people, and it urged anyone who has not gotten their initial booster dose to do so.

“Based on an analysis of emerging data, a second booster dose of either the Pfizer-BioNTech or Moderna COVID-19 vaccine could help increase protection levels for these higher-risk individuals,” said Dr. Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research. “Additionally, the data show that an initial booster dose is critical in helping to protect all adults from the potentially severe outcomes of COVID-19. So, those who have not received their initial booster dose are strongly encouraged to do so.”

The agency said the benefits of the second booster outweigh any risks among these groups. For anyone else, the authorization of the first booster dose remains unchanged.

Eligible Connecticut residents who want another booster can find a vaccination location on the state's website. More than three-quarters of Connecticut residents are fully vaccinated.

"With an unknown trajectory of the BA.2 Omicron subvariant, getting this booster is one additional way that older adults can protect themselves," state Department of Public Health Commissioner Dr. Manisha Juthani said in a statement.

COVID-19 case numbers, hospitalizations and deaths are declining nationwide, but health officials are keeping an eye on the worrying omicron subvariant, BA.2, or “stealth omicron,” which has caused new cases to more than double in the United Kingdom in recent weeks, National Public Radio reported.

Gov. Ned Lamont warned that a surge connected to the BA.2 subvariant was possible in Connecticut.

“We may see a surge from the BA.2 Covid variant this spring, and we know how to manage it if needed,” he tweeted. “Have self-tests and quality masks handy, and get your booster if eligible.”

Connecticut reported 365 coronavirus cases Tuesday and a daily positive test rate of 3.65 percent. COVID-19 hospitalizations increased by seven patients, up to 101 hospitalized.

The state’s seven-day moving positive test rate average has been incrementally increasing, but still remains well below rates seen earlier in the year. The latest seven-day average was 2.24 percent, which is the highest it’s been since late February.

The moving seven-day average for daily cases was 377 as of Tuesday. The average has been creeping up recently, but is still a vast improvement from earlier in the month. The seven-day average was 740 daily cases on March 8.

Approval of a second booster is a complicated matter, though, because health experts don’t know the timing of the next COVID-19 surge, The Associated Press reported. It is more difficult to predict for a number of reasons, including the use of at-home tests, whose results aren't included in government data; and the government’s shift in data collection to focus on hospitalizations, which occur after a surge has arrived.

Citing real-world data from Israel, among a handful of countries that offer a second booster shot, Pfizer asked the FDA to greenlight the additional booster shot for people 65 and older. The FDA also cited data from Israel, saying the second Pfizer booster revealed no new safety concerns.

Moderna followed suit, asking the FDA to approve a broad emergency use application of an additional vaccine booster to include any adult over 18 who has gotten any authorized or approved vaccine.

For the second Moderna booster, the agency said the decision was informed by experience with the Pfizer shot and data from a study that showed no new safety concerns up to three weeks after the second booster was administered.

Both vaccine makers cited studies that confirmed infections were two times lower and rates of severe illness were four times lower among people who received the second Pfizer booster, compared to people who received only one, according to a news release.

The administration didn’t need the blessing of either the FDA or Centers for Disease Control and Prevention to move forward, but Dr. Jesse L. Goodman, a former chief scientist at the FDA, had said skipping the advisory committees would be a mistake.

“This is a complex decision that involves a pretty deep dive, and I think it would really benefit from public discussion,” Goodman, a former chief scientist at the FDA, told the Times. “I would not want to see an advisory committee skipped on this.”
