pregnancy

Several results confirm that vaccination against covid-19 does not affect fertility. One of them, carried out on some 2,000 couples and published in the American Journal of Epidemiology, compares the ability to conceive naturally in vaccinated and unvaccinated couples. The other, in Obstetrics & Gynecology, studies some 1,300 vaccinated and unvaccinated women who have used different assisted reproductive techniques. Neither paper finds a link between vaccination and pregnancy.

A study published in Science Translational Medicine shows that pregnant women are more dependent on a second dose of vaccine to develop a full immune response. The work sheds light on how pregnancy affects immunity against SARS-CoV-2, a question still little studied. Obstetrician Mar Gil stresses the importance of getting pregnant women vaccinated, and of their inclusion in clinical trials.
