A medical freedom group recently promoted misinformation and speculation about the tetanus vaccine, including the long-disproven myth that it is dangerous during pregnancy and causes infertility. This false claim has repeatedly been promoted by vaccine opponents worldwide.
The persistence of this misinformation increases its risk. The disproven rumor that tetanus vaccines were used to sterilize Kenyan women is based on a widely circulated rumor that the vaccine contains the hormone HCG, which is produced during pregnancy. Multiple studies determined that the tetanus vaccine does not contain the hormone.
