Moderna: Initial booster data shows good results on omicron

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.
