US CDC backs COVID-19 vaccine boosters


The US Centers for Disease Control and Prevention (CDC) on Friday backed a booster shot of the Pfizer/BioNTech COVID-19 vaccine for Americans aged 65 and older, adults with underlying medical conditions and adults in high-risk working and institutional settings.

The decision by CDC Director Rochelle Walensky is aligned with the U.S. Food and Drug Administration’s authorization of the shot earlier this week and follows an August announcement of a broad booster rollout from her and other top U.S. health officials.

The CDC recommendation cleared the way for booster shots to start on Friday. Walgreens Boots Alliance and Walmart said on Friday that boosters were available immediately for eligible individuals. They will also be rolled out in long-term care facilities and vaccination centers.

Walensky’s decision broke from a recommendation on Thursday by a group of expert outside advisors to the agency who had said that a narrower group of people should receive the extra shot. The CDC director is not obliged to follow the advice of the panel.

“This was a scientific close call. In that situation, it was my call to make,” she told reporters at a White House briefing.

The advisory panel specifically excluded people in high-risk jobs and those in close living conditions due in part to concerns about a rare heart inflammation side effect that has occurred primarily in younger men. They were also concerned the recommendation would be too broad to implement effectively.

Walensky said the policy protects healthcare and frontline workers as well as religious and ethnic minority communities disproportionately impacted by the pandemic.

“Many of our frontline workers, essential workers, and those in congregate settings, come from communities that have already been hardest hit,” she said. “It was a decision about providing rather than withholding access.”

The panel did recommend boosters for older people and some with medical conditions that put them at higher risk of severe COVID-19.

The authorization opens boosters to more than 20 million people who received their second Pfizer/BioNTech shot more than six months ago.

The CDC on Thursday told its advisers that there would be no requirements to submit documentation to prove that people have the underlying conditions or work in at-risk settings.

Scientists have been divided over the need for COVID-19 vaccine boosters, with some including those from the FDA and the World Health Organization saying there is inadequate evidence that they are needed by anyone other than older people and that priority should be given to people around the world who have yet to receive a first shot.

Pfizer and U.S. health officials have argued that the boosters prevent hospitalizations and deaths and that emerging data indicates they can slow mild infections as well.

The highly transmissible Delta variant of the coronavirus has driven a surge in COVID-19 cases in the United States that peaked on Sept. 1 and has since fallen about 25% to just over 120,000 cases per day, based on a 7-day moving average.

Top U.S. infectious diseases expert Dr. Anthony Fauci has said the country needs to get down to around 10,000 cases a day to see an end to the health crisis in the United States.
