Menstrual Dysfunction and COVID19 Vaccine

Introduction: There has been an increasing concern that the vaccination against the novel COVID19 disease is likely to provoke various side effects for the general population including menstrual cycle dysfunctions for women in the reproductive age. There are some risk factors that enhance the possibility for post-vaccine implications on the menstrual health. Such risk factors are smoking, past COVID19 infection and the lack of usage of oral estrogen- containing contraceptives. Aim. The aim of this report is to clarify the relationship between the vaccines against the SARS-CoV-2 and the menstrual cycle dysfunction in the women of reproductive age. Materials and Methods: an extend research was made via the PubMed database using the following keywords: “menstrual”, “dysfunction”, “COVID19”, “vaccine”. No further filters and eliminations were used. Conclusion: There are several mechanisms through which vaccines are able to alter the menstruation cycles. The irregularities are not permanent and after a short period of time, menstrual cycles return to normal. Women of reproductive age are still encouraged to be vaccinated.
