Covid vaccines being given to millions of people in the UK are extremely safe, with mild expected side-effects, says the country’s drugs regulator.
It assessed safety reports from nearly seven million doses given up to 24 January – mostly with the Pfizer jab.
Some 22,820 suspected reactions were reported. Almost all were mild, such as a sore arm or flu-like illness.
Oxford Scientists and AstraZeneca, like many other Covid vaccine developers, are working on updating their shots to make sure they are a good match as the virus continues to mutate. The UK Government has announced a deal with biopharmaceutical company CureVac to develop vaccines against future variants.
Vaccines are seen as the way out of the pandemic, and all of the evidence so far suggests they are safe and effective.
