US recommends Covid boosters for people 65 and above

Washington - Medical experts also want health care workers and people at high risk of occupational exposure to get booster jabs

A panel of leading US medical experts advising the government voted in favour of authorising boosters of Pfizer's coronavirus vaccine for everyone aged 65 and up, as well as people at high risk of developing severe Covid.

The same committee however rejected an initial proposal, submitted by Pfizer and backed by President Joe Biden's administration, to fully approve boosters to everyone aged 16 and over.

The decisions came after a day-long meeting full of data presentations and at times charged debate that was convened by the Food and Drug Administration (FDA). Tens of millions of Americans will soon be eligible for a third shot.

"I think this should demonstrate to the public that the members of this committee are independent of the FDA, and that in fact we do bring our voices to the table," said Archana Chatterjee, dean of Chicago Medical School.

The panel - which included vaccinologists, infectious disease researchers, and epidemiologists - concluded that the benefit-risk balance differed for younger people, especially males at risk for myocarditis.

A clinical trial for the booster involved just over 300 people, which they felt was too small to be able to draw firm conclusions about safety.

The panel voted 16-2 against granting a third dose full approval.

They were then presented with a new motion, and voted 18-0 for granting emergency authorization for people aged over 65 and those at high risk. They agreed this should extend to health care workers and people at high risk of occupational exposure.

Now the issue turns to another committee, this time convened by the Centers for Disease Control and Prevention (CDC) on September 22-23 to further define who is eligible and decide on rollout.

Pfizer will work with the FDA to address the committee's questions as "we continue to believe in the benefits of a booster dose for a broader population," Kathrin Jansen, head of vaccine research and development at the company, said in a statement.

Even prior to the meeting, the Food and Drug Administration (FDA) had struck a cautious note.

In its briefing document, the FDA stated: "Data indicate that currently US-licensed or authorized Covid-19 vaccines still afford protection against severe Covid-19 disease and death."

Two senior FDA officials meanwhile co-signed a Viewpoint in The Lancet this week opposing boosters for the general population, in what was seen as a rebuke of the White House for taking a decision before consulting its scientific agencies, effectively placing the cart before the horse.
