evidence: Can COVID-19 vaccines affect fertility? Infertility has not been a problem for men or women for any of the COVID-19 vaccines. One study noted vaccines do not affect conception by either partner. Prior COVID-19 infection among women also does not affect conception. However, recent COVID-19 infection among males does affect their fertility and ability to conceive. [...] COVID-19 vaccination lowers your risk of COVID-19 hospitalization and death. The known risks of COVID-19 illness and its related, possibly severe complications, such as long-term health problems, hospitalization and even death, far outweigh the potential risks of having a rare adverse reaction to vaccination like myocarditis or blood clots. COVID-19 vaccines do not affect pregnancy or fertility.
