While the Norwegian health authorities said they cannot rule out a connection between vaccination and symptoms that range from lost periods to heavier bleeding (including after menopause), the general advice for all adults aged 18 and over to get their COVID-19 shot remains in place. The Norwegian Medicines Agency has so far processed 1,264 reports of menstrual disorders after COVID-19 vaccination.
Some of the women lost their periods completely, others experienced bleeding after menopause, whereas many women suffered from more pain and heavier bleeding, TV2 has reported.
Doctor Lill Trogstad of the Norwegian Institute of Public Health (FHI) said that the connection between the menstrual disorders and vaccines cannot be ruled out.
The reported side effects were said to be related to all three vaccines used in the Norwegian vaccination programme (Pfizer, Moderna, and AstraZeneca). According to the Medicines Agency, it is currently impossible to say whether any of these stands out.
