Pfizer-BioNTech to Seek U.S. OK for Second Covid Booster for 65 and Older, Report Says

Pfizer Inc and its German partner BioNTech SE will seek emergency use authorization for a second booster shot of their Covid-19 vaccine for people aged 65 and older as soon as Tuesday, the Washington Post reported.

The submission to the U.S. Food and Drug Administration is expected to include data collected in Israel, where a second booster is authorized for many people over age 18, the report said, citing three people familiar with the matter.

Neither company nor the FDA immediately responded to Reuters requests for comment.

Israel has been offering a fourth shot since the beginning of January to people over age 60, and since the end of January to those over 18 who met criteria such as being immunocompromised or at risk of infection through their work.

U.S. health officials including top infectious disease expert Dr. Anthony Fauci have raised the prospects of a fourth shot many times, suggesting one might be needed for older people and to prepare for the possibility of another surge of cases.

U.S. Centers for Disease Control and Prevention data has shown that vaccine efficacy wanes over time and that third shots help restore that efficacy, but it has not released comprehensive data based on age or health status.

Pfizer Chief Executive Albert Bourla has several times in the past week told reporters that a fourth dose of the vaccine will be needed to offset waning protection gained with the third shot.

He told the Washington Post last week that data suggests a fourth dose dramatically improves protection against the dominant Omicron variant of the virus compared to the third dose after three-to-six months.

The data Israel previously released was mixed.

Israel in late January said a fourth dose doubled protection against infection and increased protection against severe disease by 3 to 5 times compared to those who had received three shots, based on health ministry data.

That analysis was more favorable than a small study of Israeli healthcare workers. When given at least four months after the third shot, a fourth dose was 30% effective against infection for the Pfizer-BioNTech vaccine and 11% for the Moderna Inc vaccine.

“The elderly and immunocompromised are the groups that would benefit the most from additional boost,” said Dan Barouch, a Harvard vaccine researcher. “I think the data is supportive, but the benefits appear to be relatively small.”

Pfizer is looking at how a fourth dose performs in its own study of about 600 people. It and Moderna are betting additional booster doses will be needed for new virus variants that emerge.

While COVID cases are in retreat in the United State and much of the world, infections are rising in China as the Omicron variant spreads. In the UK and Europe, there has been a reversal in the downward trend of COVID cases as economies have opened up and a second version of Omicron circulates.

Pfizer last month said eventual 2022 sales of its COVID-19 vaccine may not top its current forecast of $32 billion, a 13% decline from 2021 levels.

Separately, the FDA plans to convene its expert advisory panel in early April to consider whether there should be an October or November campaign to encourage some or all adults to get additional boosters, and whether the shots should be the same as current vaccines or be retooled to counter new variants, the Washington Post reported, citing a federal official.
