An October 19 Pennsylvania Department of Health advisory about measles during pregnancy, following reports of at least six babies born with congenital measles, has prompted online questions about vaccination and immunity. Pregnant people are asking whether childhood MMR vaccination still protects them, whether they need another dose, and what to do if exposed to measles. Some commenters also confuse measles with rubella, while others downplay the risks of infection or promote natural immunity.
Some commenters are also recommending vitamin A to prevent or treat measles during pregnancy, despite warnings that it does not prevent measles and that high doses during pregnancy can harm fetal development.
Recommendation
Communicators may use the advisory to educate audiences about measles risks during pregnancy, how to confirm vaccination status or immunity, and what to do following a possible exposure. Clarifying that the MMR vaccine is recommended before pregnancy but should not be administered during pregnancy, and explaining when vaccination may be appropriate after delivery is recommended. Communications may also address false claims about vitamin A and natural immunity, including the risks of taking high doses of vitamin A during pregnancy.
