New study shows COVID-19 infection or vaccination in early pregnancy does not raise birth defect risk

Study finds no increased risk of birth defects after COVID-19 infection or vaccination in early pregnancy.

COVID-19 infection or vaccination during the first trimester of pregnancy does not increase the risk of major birth defects according to a study from Scandinavia published by The BMJ.
The study included over 343,000 liveborn single infants in Sweden, Denmark, and Norway with an estimated start of pregnancy between March 2020 and February 2022.
Researchers found no increased risk of major congenital anomalies after infection with or vaccination against COVID-19 during the first trimester.
The observational study adjusted for various factors, but cannot establish causation, suggesting that other unmeasured factors may have influenced the results.
Larger studies are needed to provide more robust evidence, but current data suggests no association between COVID-19 infection or vaccination during early pregnancy and congenital anomalies.
