Does COVID vaccination affect IVF timing or fertility?
I am due for a booster during stimulation. Will vaccination reduce IVF success or egg quality?
Short answer: COVID vaccines are not linked to infertility. Many clinics proceed with vaccination around cycles with practical spacing for fever side effects; follow your clinic's current protocol and public health guidance.
Answer #1
Fertility myths vs evidence
Large studies and reproductive societies have not found that COVID vaccination impairs fertility in women or men. Fever after any vaccine can temporarily affect sperm parameters or make you feel unwell around procedures—that is a timing issue, not vaccine-caused infertility.

Answer #2
Practical scheduling
If a feverish side-effect window might overlap retrieval or transfer, your clinic may suggest slight spacing. Do not skip medically advised vaccination out of fertility fear without discussing real risks of infection in pregnancy. Follow the latest clinic SOP.

Call your clinic or go to the hospital the same day if you have
- Severe allergic reaction after any vaccine needs emergency care
- High fever after vaccination—tell your clinic if a trigger or retrieval is imminent
