Moderna says Covid-19 booster dose works against Omicron variant in lab tests

Live Mint  

Moderna Inc. said a third dose of its Covid-19 vaccine increased immune responses against the Omicron coronavirus variant compared with two doses in lab tests, signaling the shot could still offer protection despite the variant’s mutations. Moderna also tested other experimental booster shots that target older variants, including Delta, and found they provided a comparable boost to antibody levels against Omicron as its original vaccine booster shot. Given the speed of Omicron’s spread, Moderna said its near-term priority will be to continue making booster shots of its original vaccine available. The new data on Moderna’s booster and Omicron came from lab tests that mix blood samples from vaccinated people with an engineered virus that resembles the Omicron variant.
