Covid infection during pregnancy has been associated with a higher risk of complications, hospitalization and death of the pregnant woman
There is no association between vaccinating pregnant women against the coronavirus and a higher risk of preterm birth, low birth weight or stillbirth, a new Canadian scientific study shows.
Vaccination against the coronavirus is effective and safe for pregnant women and their babies. In contrast, Covid-19 infection during pregnancy has been associated with a higher risk of complications, hospitalization and death of the pregnant woman, as well as for premature or stillbirth.
The researchers, led by Associate Professor Deshaine Fell of the University of Ottawa’s School of Epidemiology & Public Health and the Children’s Hospital of Eastern Ontario, who made the relevant publication in the British Medical Journal British Medical Journal (BMJ), analyzed data on 85,162 births in 2021, of which 43,099 were to women vaccinated with one or more doses (almost all of them had the Pfizer-BioNTech or Moderna vaccine).
It was found that the probability of preterm birth was 6.5% in vaccinated versus 6.9% in unvaccinated women, while the probability of very premature birth was 0.59% versus 0.89% respectively. The risk of giving birth to an underweight baby was 9.1% for the vaccinated versus 9.2% for the unvaccinated, while the risk of stillbirth was 0.25% versus 0.44% respectively.
Findings were similar regardless of stage (trimester) of pregnancy, number of vaccine doses, or which mRNA vaccine of the two was used.
