MHRA approves Pfizer/BioNTech’s adapted COVID-19 vaccine (Comirnaty) that targets Omicron XBB.1.5

The vaccine was approved after it was found to meet the UK regulator's standards of safety, quality and effectiveness

Approval has today been granted by the Medicines and Healthcare products Regulatory Agency (MHRA) for an adapted Pfizer/BioNTech COVID-19 vaccine that targets the Omicron XBB 1.5 subvariant, after it was found to meet the UK regulator’s standards of safety, quality and effectiveness.

The vaccine has been approved for use in individuals from 6 months of age.

The adapted vaccine works in the same way as the original vaccine by causing the immune system (the body’s natural defences) to produce antibodies and blood cells that work against the virus, so giving protection against COVID-19. All approved adapted COVID-19 vaccines help to improve the protection obtained from earlier doses of the vaccine and help give longer-term protection against getting seriously ill from COVID-19.

Notes to editors:

  • This new line extension granted by the MHRA is valid in Great Britain only and was approved via the European Commission (EC) Decision Reliance Route. This is when the marketing authorisation application made by the company references the decision made by the EMA’s Committee for Medicinal Products for Human Use (CHMP). In such cases, the MHRA considers the application together with due consideration of the EC decision, before making an independent decision on the quality, safety and effectiveness of the vaccine.
  • More information can be found in the product information for the Pfizer/BioNTech bivalent vaccine.
