Triple shot of BioNTech, Pfizer ‘effective’ against Omicron

BioNTech and Pfizer said on Wednesday a three-shot course of their Covid-19 vaccine was effective against the new Omicron variant in a laboratory test, France24 writes. Both companies said that two vaccine-doses resulted in significantly lower neutralising antibodies but a third dose of their vaccine increased the neutralising antibodies by a factor of 25, adding they could deliver an Omicron-based vaccine in March 2022 if needed.
