An adapted COVID-19 vaccine from Moderna (Spikevax) that targets the Omicron XBB 1.5 subvariant, has today been authorized by the Medicines and Healthcare products Regulatory Agency (MHRA) 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 defenses) 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.
- This new line extension was approved via the National licensing route. This marketing authorisation has been endorsed by the government's independent Commission on Human Medicines after review of the data submitted on the quality, safety and effectiveness of the vaccine.

- The Public Assessment Report will be published shortly.
