According to a new study, there is no risk of pregnancy loss associated with COVID-19 vaccinations

The study compared data, from several national health registries in Norway, on vaccinated women who suffered a miscarriage during the first trimester and those who were still pregnant at the end of the first trimester.

The results found no correlation between COVID-19 vaccinations, which included Pfizer, Moderna and AstraZeneca, and the risk of first-trimester pregnancy loss.

The study authors, which includes co-author Dr Deshayne Fell, an Associate Professor in the School of Epidemiology and Public Health in the University of Ottawa’s Faculty of Medicine and a Scientist at the Children’s Hospital of Eastern Ontario (CHEO) Research Institute, said:

COVID-19 vaccination during pregnancy

“Our study found no evidence of an increased risk for early pregnancy loss after COVID-19 vaccination and adds to the findings from other reports supporting COVID-19 vaccination during pregnancy.”

The findings are reassuring for women who were vaccinated early in pregnancy and support the growing evidence that COVID-19 vaccination during pregnancy is safe.”

COVID-19 complications

It is important that pregnant women are vaccinated since they have a higher risk of hospitalisations and COVID-19-complications, and their infants are at higher risk of being born too early. Also, vaccination during pregnancy is likely to provide protection to the newborn infant against COVID-19 infection in the first months after birth.”

The study, ‘Covid-19 Vaccination during Pregnancy and First-Trimester Miscarriage’ has been published in The New England Journal of Medicine.
