Preliminary results of one of the largest reports on the COVID-19 vaccination during pregnancy bolsters evidence that it is safe, even though the authors believe more comprehensive research is needed.
The results are based on more than 35,000 U.S. women who received either the Moderna or Pfizer shots while pregnant. The rates of miscarriage, premature births and other complications of those women were comparable to those before the pandemic.
‘'Everyone, including pregnant women and those seeking to become pregnant, should get a Covid-19 vaccine. The vaccines are safe and effective,'' the American Society for Reproductive Medicine said in a statement.
The vaccine registry shows about 13% of pregnant women reported miscarriages, less than 1% reported stillbirths, 9% reported premature births, and 2% reported birth defects. The reported rates are all within the same range observed in pregnant women before the pandemic.
Ob-gyn chair at New York's Weill Cornell Medicine Dr. Laura Riley said the new results are reassuring.
"It is great to have data to share with our patients who continue to weigh the risks and benefits of vaccination," Riley said. "They know the potential complications of Covid infection in pregnancy and now there is some safety data in human pregnancies.''
According to the study authors, continued monitoring and more evidence is needed, which includes women who get COVID-19 vaccinations in the early stages of pregnancy.
The majority of the women in the surveillance group reported injection site pain, but more serious reactions were less common.
