The Medicines and Healthcare products Regulatory Agency (MHRA) has approved a second "bivalent" vaccine as a Covid-19 booster.
The updated booster vaccine made by Pfizer/BioNTech, targeting two coronavirus variants, has been approved for use in individuals aged 12 years and above.
In each dose of the booster vaccine, 'Comirnaty bivalent Original/Omicron', half of the vaccine (15 micrograms) targets the original virus strain and the other
half (15 micrograms) targets Omicron (BA.1).
Dr June Raine, MHRA chief executive said: "I am pleased to announce that we now have a second approved vaccine for the UK Autumn booster programme. The clinical
trial of the Pfizer/BioNTech bivalent vaccine showed a strong immune response against the Omicron BA.1 variant as well as the original strain.
Bivalent vaccines are helping us to meet the challenge of an ever-evolving virus, to help protect people against Covid-19 variants. We have in place a comprehensive
safety surveillance strategy for all UK-approved Covid-19 vaccines, and this will include the updated booster we approved today."
