There is a myth circulating on social media that the Pfizer COVID-19 vaccine that may be approved by the Food and Drug Administration causes infertility in women. The rumor originated when antivaccine proponents pointed out that the spike protein of the virus and the placental protein in women share a common amino acid sequence. The new vaccine is based on genetic sequencing so speculation arose that the vaccine might prevent or disrupt pregnancies.
According to experts, the information is false, and while the vaccine was not tested on pregnant women in clinical trials, there has been no real-life evidence that the virus has interrupts real-life pregnancies.
Dr. Mary Jane Minkin, clinical professor of obstetrics and gynecology at Yale School of Medicine, told USA Today that while pregnant women may be at slightly more risk of severe illness from COVID-19, there has been no data on complications or miscarriages.
A viral blog post claimed that the vaccine contains a spike protein similar to one found in human placenta and trains the immune system to attack, which could lead to infertility in women, according to USA Today. Experts said that the coronavirus’ spike protein is not similar to the protein that helps develop the placenta in a woman’s body.
''It’s very unlikely that the immune system will confuse these two because it’s a very small part of the molecule,'' Minkin told USA Today. ''They don’t look similar enough that the body would create an antibody to attack it.''
In the other hand, Israeli researchers found that the mild to moderate cases of COVID-19 coronavirus can reduce male fertility.
