Does vaccination influence my menstrual cycle?

Irregular periods are generally not uncommon. They are frequently triggered by stress, an unhealthy lifestyle, infections, the intake of certain medications or thyroid disorders. There may also be changes in the period cycle after vaccinations. We know this from influenza and HPV vaccinations.

Vaccinations for Covid-19 with mRNA vaccines, too, may cause irregular periods and unexpected bleeding. These changes in periods, however, are only temporary and have no permanent impact on a woman’s hormonal balance or fertility!
