Comparative Analysis of Vertical Transmission of SARS-CoV-2 Antibodies in Vaccinated and Non-Vaccinated Pregnant Women

Pregnancy is a risk factor for developing a severe, complicated form of COVID-19. Medical reports have revealed that pregnancy increases three times the risk of ICU admission and 1.7 times the risk of death in patients with COVID-19. The crossing of the placenta by the antibodies generated through v...

description Pregnancy is a risk factor for developing a severe, complicated form of COVID-19. Medical reports have revealed that pregnancy increases three times the risk of ICU admission and 1.7 times the risk of death in patients with COVID-19. The crossing of the placenta by the antibodies generated through vaccination offer a level of protection that should not be ignored. We aimed to comparatively analyze the levels of SARS-CoV-2 IgG and IgM antibodies in pregnant women who have had this infection during pregnancy or have undergone a complete vaccination cycle during pregnancy, as well as antibody levels in newborns. The inclusion criterion was history of SARS-CoV-2 infection during pregnancy or COVID-19 complete vaccination. For each case the peri-partum values of IgG and IgM SARSCoV- 2 antibodies were analyzed in the same laboratory along with those of their newborns. The vaccination rate in our study group was about 6%. All cases had a significant value of protective IgG SARS-CoV-2 antibodies and the level of protective antibodies of the newborns closely followed maternal values. From the cases with SARS-CoV-2 infection during pregnancy, only 16.6% had a protective level of antibodies and 75% of the newborns from these cases had protective levels of IgG SARS-CoV-2 antibodies. Our results clearly plead in favor of vaccination in pregnancy which provides significant benefits for both mothers and infants.
