Vaccination against COVID-19 in pregnancy is safe and effective (Literature review)

ABSTRACT

This review provides current information on safety and effectiveness of COVID-19 vaccines for pregnant and lactating patients. 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. On the other hand, the negative consequences of COVID-19 infection are well known both on the reproductive health of men and on the course and outcomes of pregnancy. Results of analysis of data on the course of pregnancy, childbirth, the postpartum period and the condition of newborns in 891 patients with coronavirus infection and in 1694 patients without coronavirus infection of the obstetric department of the Filatov City Clinical Hospital No. 15 for the period from January 1, 2020 to April 25, 2021. It was revealed that patients with coronavirus infection have a higher risk of preterm birth, a higher probability of having premature babies, and a higher percentage of operative delivery, than in patients without coronavirus infection. 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. No data has been received to support vertical transmission of the virus from a mother infected with COVID-19 to her fetus. There were no specific changes in placental tissue in patients with coronavirus infection. Based on the available results of clinical studies on the safety and efficacy of COVID-19 vaccines, all mentioned professional communities (WHO, CDC, ACOG, RCOG, RANZCOG, etc.) strongly recommend getting COVID-19 vaccine for women who are pregnant or breastfeeding. © 2021, Media Sphera Publishing Group.
