AstraZeneca and Pfizer vaccines associated with rare but potentially serious side effects in study

Very rare and potentially serious new complications have been associated with both the Oxford-AstraZeneca and Pfizer jabs in a new study.
Scientists found that for every million first doses administered of the Oxford-Astrazeneca vaccine there were about four extra cases of Guillain-Barré syndrome, a neurological condition in which people can experience numbness, tingling and muscle weakness.
