A booster dose of Moderna's mRNA-1273 vaccine protects against the new covid-19 variant, omicron, and can increase antibodies 83-fold, noam reported Monday, citing a study that has yet to be peer reviewed.

Laboratory tests have shown that the current 50 microgram booster dose of the mRNA-1273 vaccine has increased antibody levels by about 37 times against Omicron infection. At the full dose of 100 micrograms, on the other hand, antibody levels are 83 times higher.

Although these data advance an encouraging prognosis, Moderna's CEO felt in a statement that a specific vaccine to combat omicron still needs to be produced.

Modernan reports that omicron reduces antibody levels in infected people, but 29 days after the booster dose was given, antibody levels against a pseudovirus, designed to mimic the omicron variant, increased in all people under observation.

However, for now, the 100 microgram dose is safe, but Moderna admits that it generates more adverse reactions.

Covid-19 has caused more than 5.33 million deaths worldwide since the pandemic began.
