Posted on December 30th, 2020 Courtesy The Times (UK) Astrazeneca chief promises 2 million doses a week The Covid vaccine developed by Oxford University and the drugmaker Astrazeneca has been approved for use in Britain, with government advisers saying that a single shot could achieve 70 per cent protection. The jab was authorised by the Medicines and Healthcare Products Regulatory Agency (MHRA) this morning amid mounting concerns over the new fast-spreading coronavirus strain and rising hospital admissions. The first injections are due on Monday. The Oxford vaccine requires two shots for maximum protection but the strategy for the immunisation campaign has been changed to prioritise giving as many vulnerable people as possible their first dose. Three weeks after getting a first shot of the Oxford vaccine people should have 70 per cent protection against symptomatic Covid, government scientific advisers said today.
