The COVID-19 vaccine can affect women’s fertility.

The COVID-19 vaccination has no impact on fertility. The fact is that the COVID-19 vaccination stimulates the body to produce copies of the spike protein seen on the surface of the coronavirus. This "trains" the body's immune system to fight viruses that have that specific spike protein. A bogus article on social media claimed that the spike protein on this coronavirus was the same as another spike protein called syncitin-1, which is involved in the development and attachment of the placenta during pregnancy. According to the misleading article, receiving the COVID-19 vaccination will force a woman's body to resist this different spike protein, affecting her fertility.

The two spike proteins are fully separate and unique, and receiving the COVID-19 vaccination will have no effect on the fertility of women attempting to conceive, including through in vitro fertilization treatments. During the Pfizer vaccination trials, 23 of the study's 23 female participants became pregnant, and the only one who miscarried had received a placebo rather than the genuine vaccine.

Getting COVID-19, on the other hand, might have major consequences for the mother's health and pregnancy. Find out more about the coronavirus and pregnancy. Johns Hopkins Medicine urges women to contact their medical providers if they have any more questions about COVID-19 and fertility or pregnancy.
