A folic acid supplement is recommended during pregnancy and prior to conception because it reduces the risk of neural tube defects in babies. Social media posts have claimed that people should avoid folic acid in favor of a different form of the vitamin, but folic acid is the only one that has been established to help prevent birth defects.
Q: Is the use of acetaminophen during pregnancy linked to autism or ADHD?
A: There is currently no strong evidence that acetaminophen use during pregnancy causes autism or ADHD in children. Expert groups continue to recommend use of the drug during pregnancy when necessary and in consultation with a doctor.
Studies have repeatedly found that COVID-19 vaccination does not increase the risk of miscarriage. Bogus claims that 44% of pregnant women in the Pfizer/BioNTech COVID-19 vaccine trial miscarried rely on a faulty tally of miscarriages that counted each miscarriage twice and included miscarriages from people in the placebo group.
The Centers for Disease Control and Prevention recommends COVID-19 vaccines for pregnant people, and the World Health Organization says the vaccines are safe for them. Yet online articles cite a Canadian doctor who falsely claims that the vaccines have caused an unusually high number of stillbirths in Canadian hospitals. A hospital representative told us there was “no truth to this claim.”
Federal vaccine monitoring systems have identified no safety concerns with the COVID-19 vaccines for pregnant people. Preliminary Centers for Disease Control and Prevention data show that miscarriage is not more frequent than expected in vaccinated people. Online posts, however, falsely contend that such data, as reported in a CDC publication, show an 82% miscarriage rate.
Clinical trials and medical studies have indicated that the COVID-19 vaccines are safe for pregnant people. But online posts misrepresent unverified reports submitted to vaccine monitoring systems in the U.S. and Europe to misleadingly suggest “920 women” lost babies because they received COVID-19 vaccines.
Q: Do the COVID-19 vaccines cause infertility?
A: There’s no evidence that approved vaccines cause fertility loss. Although clinical trials did not study the issue, loss of fertility has not been reported among thousands of trial participants nor confirmed as an adverse event among millions who have been vaccinated.
