Nu există nicio dovadă că vaccinarea împotriva COVID-19 ar putea afecta fertilitatea. Au existat unele rapoarte privind modificări minore și temporare ale ciclului menstrual al femeilor după vaccinare. Se efectuează mai multe cercetări pentru a înțelege dacă există o legătură cauzală și mecanisme potențiale implicate, de exemplu dacă vaccinarea provoacă un răspuns imunitar care ar putea influența temporar ciclul menstrual. În orice caz, cu dovezile disponibile în prezent, nu există niciun motiv pentru a lega vaccinarea COVID-19 de problemele de fertilitate.
