The committee unanimously voted that the new jabs should be monovalent — meaning they are designed to protect against one variant of Covid — and target a member of the XBB family.
Those strains of Covid are descendants of the omicron variant, which caused cases to surge to record levels early last year.
Advisors also generally agreed that the new shots should specifically target a variant called XBB.1.5.
There is also uncertainty about which age groups the FDA and CDC will advise to receive the updated shots this fall.
But it's unclear how many Americans will roll up their sleeves to take the updated shots later this year.
