Call for investigation of menstrual changes after Covid jabs
Changes to periods and unexpected vaginal bleeding after having a Covid vaccine should be investigated to reassure women, says a leading immunologist specialising in fertility.
Writing in the BMJ, Dr Victoria Male, from Imperial College London, said the body's immune response was the likely cause, not something in the vaccines. There is no evidence they have any impact on pregnancy or fertility.
The UK's regulator has received more than 30,000 reports of period problems. These include heavier than usual periods, delayed periods and unexpected bleeding after all three Covid vaccines, out of more than 47 million doses given to women in the UK to date.
After reviewing the reports, the Medicines and Healthcare products Regulatory Agency (MHRA) says it "does not support a link" between Covid vaccines and the symptoms.
However, writing in an opinion piece in the BMJ, Dr Male says "robust research" into reports of period problems would help to counter misinformation around the vaccines.
"Vaccine hesitancy among young women is largely driven by false claims that COVID-19 vaccines could harm their chances of future pregnancy. Failing to thoroughly investigate reports of menstrual changes after vaccination is likely to fuel these fears."
"If a link between vaccination and menstrual changes is confirmed, this information will allow people to plan for potentially altered cycles," she said.
