Pfizer, BioNTech Say Their COVID-19 Vaccine Neutralizes Omicron Variant After Three Doses in Preliminary Study Results

7:29AM ET 12/08/2021 MT Newswires
Pfizer (PFE) and BioNTech (BNTX) said Wednesday preliminary results from a laboratory study showed antibodies from their COVID-19 vaccine, BNT162b2, neutralize the virus' omicron variant after three doses.

Serum levels one month after the vaccine's third dose neutralized omicron to levels comparable with those observed for the wild-type SARS-CoV-2 spike protein after two doses, the companies said.

Pfizer and BioNTech said two shots of the vaccine may not be sufficient to protect against the variant, although they may still protect against severe forms of the disease.

The companies said they have "high confidence" that they can deliver an omicron-based vaccine in March 2022, if needed.
