Moderna: initial data on COVID-19 boosters shows good results on omicron

Moderna said Monday that the booster dose of the COVID-19 vaccine should provide protection against the rapidly spreading omicron variant.

Moderna said laboratory tests showed that the half-dose booster vaccine increased 37 times the level of so-called neutralizing antibodies, which are able to fight the omicron.

And the full-dose booster was even stronger, causing an 83-fold jump in antibody levels, albeit with an increase in common side effects, the company said. While semi-dose injections are used for most Moderna boosters, a third full dose is recommended for people with weakened immune systems.

Moderna has published preliminary laboratory data in a press release that has not yet been scientifically reviewed. But testing by the US National Institutes of Health, announced last week by Dr. Anthony Fauci, found a similar leap.

Pfizer’s testing also showed that its COVID-19 vaccine caused an equally big jump in antibodies fighting omicron. Vaccines produced by Pfizer and Moderna, made using mRNA technology, are used in many countries around the world to fight the coronavirus.
