Do the Covid-19 vaccines affect my chances of pregnancy?

No, there’s no evidence that any vaccines, including COVID-19 vaccines, influence your chances of getting pregnant despite a myth suggesting otherwise. Medical experts say there’s no biological reason the shots would affect fertility.

In Pfizer’s study, a similar number of women became pregnant in the group given the vaccine as in the group given dummy shots. Researchers are starting to study anecdotal reports of short-term changes to periods after the vaccine, but there’s no indication so far that the shots put fertility at risk, said Dr. Mary Jane Minkin, a gynecologist and professor at the Yale University School of Medicine.
