Menstrual disturbances are one of the more regularly reported suspected side-effects of Covid-19 vaccines, Ireland’s drug watchdog said yesterday.

In its latest overview of Covid-19 vaccines, the Health Products Regulatory Authority (HPRA) said that as of March 15 it had received 112 reports of women missing a period after getting the Pfizer or Moderna jab.

It got 402 reports of heavier menstrual bleeding, mostly after the Pfizer vaccine.

“In the vast majority of cases, reports were received directly from a vaccinated woman describing a menstrual disturbance with no associated medical condition,” the HPRA said.

“Women who are concerned about prolonged or unusual menstrual disturbances may wish to seek medical advice, in particular if unexpected vaginal bleeding, for example, in a post-menopausal woman is experienced.”

The update said that with 7.9 million Covid-19 vaccines administered here at that point, the overall assessment was that benefits outweighed risks.

Looking at the vaccination of children and adolescents aged five to 17 at that stage, who had received a combined total of 852,000 jabs, it said that, overall, the reports of suspected side-effects were consistent with those for adults – mostly mild and moderate.

The most regularly reported side-effects were dizziness, fainting, headache, fever, nausea and tiredness.

The European Medicines Agency (EMA) has recommended the Moderna vaccine information be updated to raise awareness of potential risk in patients with a history of Capillary Leak

This is an extremely rare but serious disorder involving leakage of fluid from small blood vessels; they should speak to their doctor before getting the Moderna jab.

No reports of suspected cases following the shot here were received.

As of March 15, the HPRA got 126 reports of myocarditis, pericarditis – inflammation around the heart – or both. Five cases involved an adolescent aged 12 to 17.

It said all cases were carefully reviewed,
and not all were necessarily caused by the vaccine.

Meanwhile, the EMA yesterday gave approval to a first-of-a-kind drug that reduces the risk of people getting Covid.

The antibody cocktail, called Evusheld and made by AstraZeneca, could potentially benefit immunosuppressed people in this country who do not respond to vaccines.

Evusheld was found to cut the risk of getting symptomatic Covid by around 80pc for up to six months in a clinical trial last year.

It is administered through two simultaneous injections and uses antibodies – immune proteins – that have been modified in a laboratory to make them last longer.

While vaccines train the body to respond to Covid, this drug is believed to skip this process and make the antibodies readily available.
