Various vaccine types, information regarding reproductive toxicology studies and vaccines efficacy against variants of concern are described in the article. The review also reflects practice guidelines of international professional communities on the use of COVID-19 vaccines in pregnancy, including the World Health Organization, RCOG (Royal College of Obstetricians and Gynecologists), ACOG (American College of Obstetricians and Gynecologists), RANZCOG (Royal Australian and New Zealand College of Obstetricians and Gynaecologists), etc. Currently, there is no evidence of a negative impact of COVID-19 vaccines on male and women’s reproductive health.

Newborn children in patients with coronavirus infection were more often admitted to the intensive care unit, than children of patients without coronavirus infection. Patients with coronavirus infection have a higher perinatal mortality rate than patients without coronavirus infection.
