There is no evidence that getting a COVID-19 vaccine makes it harder to get pregnant. Several studies of people undergoing in-vitro fertilization (IVF) found that getting a COVID-19 mRNA vaccine did not affect the body functions responsible for fertility. Professional associations for reproductive medicine recommend that people undergoing fertility treatment stay up to date on recommended COVID-19 vaccines and boosters. There is no recommendation to postpone fertility treatment after getting the vaccine nor to avoid getting the vaccine after treatment.
