"It’s perfectly normal for people to notice side effects from vaccines. These tell us that the immune system is responding to fight the disease — as it should. However, far more side effects have been reported in women than in men after receiving the coronavirus vaccination in Norway, in relation to the gender distribution of the vaccine doses.

The Norwegian Medicines Agency has so far received reports of 5,635 suspected cases of side effects, 4,684 of which were reported by women. You can read their report on vaccine side effects from April 8 here (in Norwegian). And the numbers fit a bigger picture. When researchers at the US Centers for Disease Control and Prevention (CDC) analysed data from the first 13.7 million vaccine doses, they found the same thing.

Almost 80 per cent of the reported side effects were among women, although only a little over 60 per cent of those vaccinated at that time were women. One explanation may be that women are more likely to report side effects to the healthcare system. But biological differences related to gender may be part of the reason.

Women more likely to have a severe reaction.

“This gender difference is completely in line with previous reports from other vaccines,” microbiologist and immunologist Sabra Klein, from the Johns Hopkins Bloomberg School of Public Health, told The New York Times about the CDC figures.

Common side effects from the Moderna and Pfizer coronavirus vaccines:

Comirnaty (BioNTech and Pfizer).

  • More than 80% experienced pain at the injection site.
  • Fatigue, headache, muscle aches, joint pain, chills and fever. Usually passes after a few days.
  • Some people may experience swollen lymph nodes, which may persist for 7-10 days.
  • More people experienced side effects (mentioned above) after the second dose than after the first dose.

Moderna Vaccine.

  • Most people experience unpleasant side effects such as pain and swelling at the injection site, fatigue, headaches, chills, nausea / vomiting, fever, and muscle and joint pain in the first days after vaccination.

For both vaccines:

  • Most people tolerate these transient side effects well, while others experience significant discomfort a few days after vaccination. Women also more often experienced the very rare but severe reactions to the coronavirus vaccines, according to the CDC’s analysis of the first 13.7 million doses in the United States.

All 19 people who experienced so-called anaphylactic reactions after the Moderna vaccine were women. Women comprised 44 of the 47 individuals who experienced an anaphylactic reaction after the Pfizer vaccine. Most of the people who developed a rare blood clot problem after the AstraZeneca vaccine were women under the age of 60, according to a press release from the European Medicines Agency, the EMA. However, a review of the cases did not provide a basis for determining any specific risk factors, including gender or age, according to the EMA".
