Research led by Karolinska Institutet and the Norwegian Institute of Public Health has determined that vaccination against a 2019-based disease known as COVID-19 through the use of Pfizer-BioNTech vaccines does not increase the risk of pregnancy complications.
As posted online in JAMA, researchers had examined the outcomes of nearly 160,000 pregnancies.
The majority of the women in gestation had been administered a vaccine after week 12, with nearly all receiving the mRNA vaccine from Pfizer-BioNTech.
What researchers determined based on their findings: “In this population-based study conducted in Sweden and Norway, vaccination against SARS-CoV-2 during pregnancy, compared with no SARS-CoV-2 vaccination during pregnancy, was not significantly associated with an increased risk of adverse pregnancy outcomes.”
“The majority of the vaccinations were with mRNA vaccines during the second and third trimesters of pregnancy, which should be considered in interpreting the findings,” the researchers also concluded.
The findings were published on March 24th, 2022.
