The government of Britain approved the Pfizer-BioNTech Covid-19 vaccine on Wednesday on the advice of its medicines regulator.
The vaccine will be made available across the UK from next week.
In a statement released on Wednesday, the UK Department of Health and Social Care said, "The Government has today accepted the recommendation from the independent Medicines and Healthcare products Regulatory Agency (MHRA) to approve Pfizer-BioNTech's Covid-19 vaccine for use."
After months of clinical trials and thorough analysis of data, the MHRA experts have concluded that the vaccine meets its strict standards of safety, quality, and effectiveness.
Care home residents, health and care staff, the elderly and the clinically extremely vulnerable will receive the vaccine on priority basis.
"The Joint Committee on Vaccinations and Immunisations (JCVI) will shortly publish its final advice for the priority groups to receive the vaccine," the spokesperson said.
