The UK has become the first country to approve a dual vaccine that controls both the original Covid virus and the newer Omicron strain.
According to foreign media, the original vaccines used in the pandemic were designed to train the body to fight the first form of the virus that emerged in Wuhan, China.
The Medicines and Healthcare Products Regulatory Agency (MHRA) has approved Mode a's bivalent vaccine, which targets both the original Covid strain and the Omicron strain.
An updated version of the Mode a vaccine already in use for first, second and booster doses, known as mRNA-1273.214, will be the first dose approved in the UK that targets two strains of the virus.
Dr. Paul Burton, Mode a's chief medical officer, previously said the new jab could boost a person's antibodies to levels that are only needed annually.
