Pfizer, BioNTech vaccine neutralises Omicron with three shots

BioNTech and Pfizer said on Wednesday a three-shot course of their COVID-19 vaccine was able to neutralise the new Omicron variant in a laboratory test and they could deliver an upgraded vaccine in March 2022 if needed, Trend reports citing Reuters.

The German and U.S. companies said two doses of their vaccine resulted in significantly lower neutralising antibodies but a third dose boosted those antibodies by a factor of 25.

"The first line of defence, with two doses of vaccination, might be compromised and three doses of vaccination are required to restore protection," BioNTech Chief Medical Officer Ozlem Tuereci said at a press conference. The companies suggested that two doses may still protect against severe disease.
