The British Medicines Agency MHRA has been the first in the world to approve a vaccine against different variants of the coronavirus.

As the Ministry of Health in London announced on Monday, the preparation called "Spikevax bivalent Original/Omicron" from the US pharmaceutical company Moderna protects against both the original corona variant and Omicron.

The vaccine provides a good immune response against both the omicron subvariant BA.1 and the virus circulating in 2020, the release said.

In addition, a research analysis has shown that the vaccine is also effective against the omicron subvariants BA.4 and BA.5.

The side effects are mild, as with the first Moderna vaccine.

There are no serious safety concerns.

MHRA chief June Raine called the booster vaccine "a sharpened tool in our arsenal to protect us against this disease that continues to evolve."

The vaccine should be available as a booster in the fall.

All over 50s and certain at-risk groups are to receive a booster shot of one form or another in the UK from September.
