Most Common Covid Vaccine Side Effects Revealed in New Study Brighton News

A NEW study has listed some of the most common side effects after a coronavirus vaccination.

According to the results, headache and tenderness at the injection site are among the most reported side effects.

The study also compared AstraZeneca and Pfizer to see how the side effects of the vaccines differ.

25% of people reported broader side effects such as nausea and fatigue, but these symptoms only lasted for a day on average.

Lead scientist on the study, Professor Tim Spector of King’s College London, said the results should reassure people that side effects from vaccines are “usually mild and short-lived.”

The study, conducted by researchers from the ZOE Covid Symptom Study in conjunction with the National Institute for Health Research, analyzed self-reported symptoms in 627,383 who entered information into their symptom app within eight days of being treated. vaccination.

How do the symptoms vary depending on the vaccine?

The study found that about 70% of people receiving the Pfizer vaccine reported an injection site reaction, including redness, swelling, or tenderness.

Just under 60 percent of those who received the AstraZeneca vaccine reported the same symptoms.

About 34 percent of those who received the AstraZeneca vaccine reported systemic whole body reactions to the vaccine, such as chills or fatigue.

This figure was lower for those who received the Pfizer vaccine, at just 14% after the first dose and 22% after the second.

The most common systemic reaction was a headache.

Both types of side effects after the two types of vaccine were found to occur “at lower frequencies” than recorded in the trials, according to the study published in The Lancet Journal.

Overall, one in four (25 percent) has had a whole body reaction to the vaccination, while two-thirds (66 percent) have had a local reaction – that is, a reaction at the injection site.

Side effects varied depending on a person’s age and gender, with people under the age of 55, those who had previously contracted Covid, and women all being more likely to experience side effects.

Lead author of the article, Dr Cristina Menni of King’s College London, told the BBC that the study supports vaccine safety and should “help allay the safety concerns of people wishing to be vaccinated.”
