A new study from Sheba’s Gynecology and Maternity Center found no change in hormone levels among recipients of the Pfizer-BioNTech vaccine.
According to a new Sheba Medical Center study, COVID-19 vaccines have no notable impact on fertility in women. The study assessed levels of an ovarian reserve indicator called anti-Müllerian hormone (AMH) and found no notable difference after the vaccine was administered.
During the study, led by Prof. Jaron Rabinovici, Deputy Director of Sheba’s Gynecology and Maternity Center, 129 participants were administered both doses of the Pfizer-BioNTech COVID-19 vaccine. Hormone levels were measured three months before the first dose, as well as three months after, and compared. Participants were studied both overall and by age group.
Sheba researchers will continue to monitor participants to check for any long-term effects, and an additional follow-up study focusing on girls between the ages of 12 and 18 is planned.
Since COVID-19 vaccines first became available, some have expressed concerns about side effects. However, experts have long contradicted these claims, and Sheba’s latest study supports this conclusion. In fact, studies have indicated that COVID-19 infections could have a negative impact on fertility, underscoring the importance of receiving the vaccine.
