People with a history of significant allergic reactions should not receive the Covid vaccine, the medicines regulator has said, after two NHS workers experienced symptoms on Wednesday.

Both of the NHS staff carry adrenaline autoinjectors, suggesting they have suffered reactions in the past. These kind of devices, of which the best-known brand is the EpiPen, administer a swift adrenaline boost to counter allergic reactions that occur when some people, for instance, eat nuts.
