A modified coronavirus vaccine that targets the Omicron variant can be administered as a booster dose to broaden immunity, a technical advisory group set up the World Health Organization said on Friday. Such a variant-adapted vaccine may benefit those who have already received the primary series of shots, the agency's panel on COVID-19 Vaccine Composition said, citing available data.
The vaccines could be considered for use globally by the agency once they get emergency use authorization or an approval by a stringent national regulatory authority. Vaccine makers including Moderna and Pfizer Inc are developing a potential next generation booster targeted at both the Omicron variant as well as the original strain of the coronavirus.
Moderna last week said a new version of its vaccine produced a better immune response against Omicron than the original shot, while the European Medicines Agency this week began rolling reviews of the variant-adapted COVID-19 vaccines from Moderna and Pfizer.
