Fertility Specialist at Sheba Medical Center Studying Impact of Pfizer COVID-19 Vaccine on Male Fertility

Unfounded claims have attempted to correlate the mRNA-based vaccines rapidly developed to address COVID-19 infection and fertility in both men and women. According to Dr. Jigal Haas, a fertility expert operating out of Israel’s Sheba Medical Center, a new study was organized to investigate as there is little to no medical literature covering semen analysis parameters, for example, post mRNA-based COVID-19 vaccine, whether it be Moderna (mRNA-1273) or Pfizer/BioNTech (BNT162b2). However, there is no evidence that mRNA-based vaccines cause infertility.

Where does this concern originate?

The concern that mRNA-based vaccines could cause infertility stems from information that protein called syncytin-1 is found in the placenta in mammals. It shares similar genetic instruction with part of the SARS-CoV-2 spike protein. The hypothesis centers on the premise that because the vaccine triggers the body to produce antibodies against the coronaviruses’ spike protein that it would also trigger antibodies to syncytin-1 which could lead to infertility. However, there is absolutely no evidence to support this claim.

For example, neither mRNA-1273 (Moderna) nor BNT162b2 (Pfizer/BioNTech) ...
