Britain on Wednesday became the first country in the world to approve AstraZeneca and Oxford University’s low-cost Covid vaccine, raising hopes it will help tackle surging cases and ease pressure on creaking health services.
The independent Medicines and Healthcare products and Regulatory Agency (MHRA) said the vaccine “met its strict standards of safety, quality and effectiveness”, and a roll-out was set for January 4.
Prime Minister Boris Johnson, who spent several days in intensive care with Covid earlier this year, called it “truly fantastic news” and “a triumph for British science”.
Britain has already approved the Pfizer/BioNTech vaccine for general use, and some 800,000 people have received the first dose in the country’s biggest-ever vaccination drive.
But as daily Covid infection rates hit record highs, the government is pinning its hopes on the Oxford/AstraZeneca jab, which is cheaper to produce, and easier to store and transport.
Unlike the Pfizer-BioNTech vaccine, it does not require ultra-low freezing temperatures and can use normal refrigerated supply chains, making it a more attractive proposition globally.
The partners, who have billed it as a “vaccine for the world”, have also promised to provide it not-for-profit to developing nations, and hope to make up to three billion doses in 2021.
The Oxford/AstraZeneca vaccine is based on a weakened version of a common cold virus (adenovirus) in chimpanzees which has been genetically changed to stop Covid-19 replicating in humans.
It delivers genetic cargo into cells, giving them instructions on how to fight SARS-CoV-2.
The vaccine costs about £2.50 ($3.40, 2.75 euros) per dose — a fraction of the price of the Moderna and Pfizer/BioNTech drugs.
On Sunday, AstraZeneca chief executive Pascal Soriot said the vaccine would provide “100 per cent protection” against severe Covid disease requiring hospitalisation.
He predicted trials would show his firm had achieved a vaccine efficacy equal to Pfizer/BioNTech at 95 per cent and Moderna at 94.5 per cent.
Earlier trials had shown varying outcomes in the AstraZeneca shot’s efficacy.
