The government has obtained 40 million doses of the vaccine and patients need two doses, which means there is not enough vaccine for the entire UK population.
“The government today accepted the recommendation of the Independent Medicines and Health Products Regulatory Agency (MHRA) to approve the use of Pfizer-BioNTech’s COVID-19 vaccine,” the government said.
“The vaccine will be available across the UK from next week. ”
The spokesperson for the Department of Health and Social Affairs added: ‘The NHS has decades of experience in implementing large-scale vaccination programs and will begin to implement their extensive preparations to provide care and support for all those eligible for vaccination.
“To contribute to the success of the vaccination program, it is essential that everyone continues to play their part and adhere to the necessary restrictions in their region so that we can further suppress the virus and allow the NHS to do its job without being overwhelmed.
“Further details will be provided shortly. ”
Health Secretary Matt Hancock said “this is fantastic news”.
“Help is on the way. The MHRA has officially authorized the Pfizer / BioNTech vaccine for COVID-19. The NHS is ready to start vaccinating early next week, ”he said in a tweet.
“The UK is the first country in the world to have a vaccine clinically approved for supply. ”
He told Sky News there would be “three modes of delivery” of the vaccine.
“The first is the hospitals themselves, of which of course we have facilities like this,” he said.
“50 hospitals across the country are already set up and are waiting to receive the vaccine as soon as it is approved, which can now happen.
“Also vaccination centers, which will be large centers where people can get vaccinated. They are in the process of being put in place ”.
