US CDC researchers study: 'No increased risk of miscarriage for pregnant women with Covid vaccine'
CDC researchers: ‘Abortion rate in women with Covid vaccine at 12.8%, close to that of general population’
Administration of the mRNA vaccine during pregnancy does not appear to be associated with an increased risk of miscarriage, compared to the general population.
This is the finding of an ongoing study conducted in the United States by a team of researchers from the Centers for Disease Control and Prevention and published on the ‘Research Square’ platform.
COVID VACCINE AND PREGNANCY: US STUDY ON ABORTION RATES
The survey involved a sample of about 2,456 pregnant women who had received the mRNA vaccine either preconceptionally or within the first 20 weeks of gestation.
The miscarriage figure was then adjusted by standardising the age of the sample, as maternal age affects the risk of miscarriage.
This standardisation led to an immediate drop in the miscarriage risk rates from 14.1% to 12.8%, bringing the risk rate back into the range of the general population.
The researchers conclude by stressing the need to strengthen the results of the survey with observational studies that include non-pregnant women.
