F.D.A. advisers recommend updated boosters that target forms of Omicron.

An expert committee recommended Tuesday that the Food and Drug Administration plan on an updated booster shot of the coronavirus vaccines that targets some form of the Omicron variant that has dominated for months. The panel’s vote paves the way for F.D.A. regulators to authorize a new formulation for the boosters that the Biden administration hopes to offer later this year, before an expected winter resurgence of the virus.
The committee debated but did not specify which formulation might work best. The F.D.A. appeared to be leaning toward a combination of the existing vaccine and two subvariants of Omicron, known as BA.4 and BA.5. According to new estimates from the Centers for Disease Control and Prevention, those two subvariants together now make up more than half of new cases in the country.
Dr. Peter Marks, who oversees the F.D.A.’s vaccine division, displayed a timeline suggesting that regulators would decide on a new vaccine composition by early July, and that a fall booster campaign could begin in October. Manufacturers of the mRNA vaccines, made by Moderna and Pfizer-BioNTech, require roughly three months to begin producing doses with a new composition.
Clinical trial results on a combination of the so-called “prototype,” or existing, vaccines and Omicron itself have received mixed reviews so far. In briefing materials, regulators suggested that such a design is “already somewhat outdated.” The panel struggled with what one member called “trying to predict the future” of where the virus is headed. Another panelist called the data “uncomfortably scant.”

Have been streaming this while the J6 Committee was on my TV.
They are discussing their votes at post time (Vote was 19 YES, 2 NO)...
= new reply since forum marked as read
They have already started manufacturing doses of what they had been working on and would be ready by around the end of July ahead of an expected fall surge of Omicron BA.4/BA.5.
Since the vaccine approval is a 4-step/2-agency process, FDA initiated this first step and at some point, CDC's ACIP will need to look at any additional clinical trial data that is still being collected on these amended types of vaccines, and would make a recommendation/approval of the new type of booster for distribution to the public.
The CDC ACIP doesn't have another meeting scheduled until October although I expect they might actually schedule one before October to get ahead of the fall/school year.
