The UK Medicines and Healthcare products Regulatory Agency announced today, Tuesday, that it has approved an updated vaccine produced by Pfizer and its German partner BioNTech, aimed specifically at combating the new variant of COVID-19 (Omicron XBB.5.1). The regulatory agency stated that the vaccine, to be sold under the name Comirnaty, is authorized for use in individuals aged six months and older. This approval comes after the vaccine was authorized by the European Medicines Agency last week. Similar to Pfizer and BioNTech, other vaccine manufacturers such as Moderna and Novavax have announced the launch of monovalent doses of their vaccines to target the XBB.5.1 variant exclusively.
