The most common side effects of the Covid-19 vaccines are pain or tenderness at the injection site, says an article on BBC.

Other side effects

Roughly one in four people had wider effects like fever, headache, nausea, and fatigue. But these only lasted on average for one day.

Safe and effective

Confidence in the vaccines has continued to grow since the end of last year, with more than 80% saying they believe the vaccines are safe and effective, compared with about 70% who said the same towards the end of 2020, according to a survey of 5,000 people.

The survey, run in association with the National Institute for Health Research, found twice as many people say they want to have the vaccine as soon as possible – although the number of people saying they would actively prefer the Oxford-AstraZeneca vaccine has fallen.

What the study says

The ZOE study researchers looked at self-reported symptoms in 627,383 people using their app in the eight days after being vaccinated.

About 70% of people having the Pfizer jab had some reaction around where the needle went in, including pain, tenderness, redness, or swelling, compared with just under 60% for the AstraZeneca jab.

The trend was reversed for those reactions that affect the whole body rather than just the site of the injection.

For the AstraZeneca jab, 34% had some “systemic” (whole-body) reaction like headache, tiredness, or chills. For the Pfizer vaccine, this was only 14% after the first dose and 22% after the second.

The most common of these side effects was a headache.
