A combination COVID-19 booster dose that targets the ancestral strain of SARS-CoV-2 and the initial omicron variant, BA.1, appears to outperform the current booster against both of those versions of the virus, Moderna reported Wednesday.

Specifically, Moderna says the combination booster increased neutralizing antibodies against omicron 8-fold, while the original booster only increased antibody levels around 4.4-fold.

The vaccine maker is angling to have this bivalent shot—dubbed mRNA-1273.214—be the go-to booster for seasonal shots this fall. The company will be submitting its data to the Food and Drug Administration in the coming weeks and says it hopes to have the bivalent booster available by late summer, if not early fall.
