MotherToBaby, a service of the non-profit Organization of Teratology Information Specialists (OTIS), offers up-to-date information to pregnant and lactating women and healthcare professionals about exposures related to pregnancy and breastfeeding. Their goal is to help reduce risks and prevent birth defects by educating the public and healthcare providers about specific agents of concern. They also conduct observational studies to evaluate the safety of medications and vaccines in pregnancy. MotherToBaby is supported by the Health Resources and Services Administration (HRSA) and is recommended by agencies such as the Centers for Disease Control and Prevention (CDC).
