What are the possible side effects?
Side effects appear to be less common in those aged over 55 than those aged 16 to 55. While they can crop up after the first dose, that shouldn’t put you off having the second dose as side effects are reported to be milder the second time around.
With the
Pfizer vaccine, any side effects you do experience should be mild or moderate and go away within a few days. In a final safety analysis of the vaccine involving more than 21,000 participants, the most common side effects were injection site pain, fatigue, and headache.
Other side effects which are quite common, impacting around one in 10 people, include: muscle pain; chills; joint pain; fever; and nausea.
