Pregnancy outcomes after maternal covid-19 vaccination during pregnancy: Preliminary data

ABSTRACT

COVID-19 significantly raises risk during pregnancy. Currently, available evidence suggests that pregnant women are more susceptible to COVID-19 than the general population [1]. Pregnant women with COVID-19 are at increased risk of severe illness, death, and adverse pregnancy outcomes [2–4]. The most effective way to prevent the disease is vaccination. Current research evidence suggests that approved COVID-19 vaccines are safe, effective, and unlikely to pose any dangers to pregnant women or fetuses [5]. National and international associations issued guidelines supporting COVID-19 vaccination in pregnant and lactating women [6]. In the Russian Federation, vaccination of pregnant women with the Gam-COVID-Vac (Sputnik V) vaccine has been permitted since June 2021. Results of animal preclinical studies suggest no adverse impact of the Gam-COVID-Vac vaccine on the course of pregnancy and fetal, embryonic, and prenatal development of offspring [7]. Objective: This study aimed to analyze pregnancy complications after maternal COVID-19 vaccination with domestic vaccines during pregnancy. Region, 75 from Trans-Baikal Krai, 76 from Yaroslavl Region, 89 from Yamalo-Nenets Autonomous Okrug, and 92 from Sevastopol. Most of the women were vaccinated with Gam-COVID-Vac (Sputnik V) vaccine (91.6%) and received two vaccine doses (57.9%). Most of the patients were vaccinated in the first trimester of pregnancy, including 683 (88.4%), 51 (6.6%), and 39 (5%) before 12 weeks, from 12 to 22 weeks, and after 22 weeks of pregnancy, respectively.
