Moderna said Monday that a booster dose of its COVID-19 vaccine should offer protection against the rapidly spreading omicron variant.
Moderna said lab tests showed the booster shots now being used — half the original dose — increased by 37 times the level of antibodies able to fight omicron.
A full-dose booster was even stronger, although it came with more of the usual side effects. Moderna's data hasn't yet undergone scientific review.
But it comes after Pfizer announced a similar antibody jump from boosters of its own COVID-19 vaccine, backing health authorities pleas for people to get the extra shots.
