Moderna says its booster significantly raises Omicron-fighting antibodies
London — Moderna announced preliminary data on Monday that it said showed a third, booster dose of its coronavirus vaccine appeared to significantly increase antibodies that can help fight off an infection with the Omicron variant. Moderna said lab tests showed Omicron-neutralizing antibodies were low after two doses of its jab, but 29 days after a booster dose of 50 micrograms, they increased about 37-fold.
The 50 microgram dose is given as a booster with the Moderna shot, but the company's data showed that a full, 100 microgram booster dose increased antibody counts even more, around 83-fold.

“Our hospitals, if things look like they’re looking now in the next week or two, are going to be very stressed,” particularly in areas of the country with low levels of vaccination, Fauci said.

Some doctors are concerned that people are so fed up with the pandemic that they won’t wear masks at a time when transmission is expected to climb.

And they’re not sticking with it.”
