COVID-19 Vaccine & Fertility: Expert Insights

Research shows no link between the COVID-19 vaccine and infertility, despite a 34,900% spike in Google searches fueled by misinformation. Leading medical groups like ASRM confirm vaccination is safe for pregnancy and conception, with over 44,000 pregnant individuals tracked in the CDC’s V-safe registry showing no increased risks.


Key Takeaways

Myth Busting: No Evidence of Fertility Impact from Vaccines

Peer-reviewed studies and organizations like the American Society for Reproductive Medicine (ASRM) confirm mRNA vaccines (Pfizer/Moderna) and Johnson & Johnson’s vaccine do not increase infertility or miscarriage risk. Vaccine ingredients do not target reproductive systems, and global clinical trials found no adverse fertility outcomes.

Pregnancy Safety: Lower Complication Rates in Vaccinated Women

CDC’s V-safe registry tracked 44,000 vaccinated pregnant women and found lower rates of gestational diabetes, preeclampsia, and stillbirth compared to baseline data. Severe pregnancy complications from actual COVID-19 infection (e.g., ICU admission, preterm birth) are far more common than vaccine-related risks.

Vaccine Symptoms: Fever & Folic Acid for Safety During Pregnancy

Post-vaccination fever in early pregnancy is rare and not linked to birth defects if women take ≥400 mcg folic acid daily (found in prenatal vitamins). The Danish cohort study of 1 million births found no increased congenital anomalies in vaccinated women, even during the first trimester.
