Covid-19 news: Moderna booster stimulates antibodies against omicron
Moderna booster jab leads to 37-fold increase in levels of antibodies against the omicron variant
A 50mg dose of the booster – the dose authorised for use in the UK and US – was found to stimulate a 37-fold increase in antibodies against omicron. A 100mg dose of the booster saw an 83-fold increase in antibodies.
The 37-fold increase “should provide some good level of protection as we go into the holiday season”, Paul Burton, Moderna’s chief medical officer, told the Washington Post.
The findings are based on antibody levels measured in the blood of 20 people 29 days after receiving a third dose of the vaccine. Moderna announced the results in a press release – the study has not yet been published or peer reviewed.
