When measles appears in the news—from outbreaks nearby to rare cases in newborns—parents often ask me the same thing: is my child protected, and what should I watch for? Fresh guidance from the American Academy of Pediatrics (AAP) on congenital measles (measles present at or soon after birth), plus clear CDC vaccine advice, is a good moment to revisit the basics.
Why measles still matters for families
Measles is a highly contagious virus that spreads through the air when someone coughs or sneezes. The CDC notes that if one person has measles, up to 9 out of 10 unprotected close contacts can catch it. It is far more than a short fever and rash. Young children can develop ear infections, diarrhea, pneumonia (a serious lung infection), swelling of the brain, or rarely, death. Babies under 5 years, pregnant people, and anyone with a weakened immune system are at higher risk of severe illness.
How MMR vaccine protects children
The best protection is the MMR vaccine (measles, mumps, and rubella). According to the CDC, two doses are about 97% effective at preventing measles; one dose is about 93% effective. Routine timing in CDC schedules is:
- First dose at 12–15 months of age
- Second dose at 4–6 years (before school), or earlier as long as doses are at least 28 days apart
Infants traveling to areas with measles risk may get an early dose from 6–11 months, then still need the usual two doses after their first birthday. In India, follow the national and IAP immunization schedule your pediatrician uses—timing can differ slightly from U.S. CDC lists, but the principle is the same: complete measles-containing vaccine on time.
Pregnancy and newborns: what the AAP is highlighting
In September 2026 the AAP published practical answers on congenital measles—when a baby is infected because the birth parent had measles around delivery. Key parent takeaways from that guidance (via AAP News and Red Book Online):
- Measles vaccine is a live vaccine, so it is not given during pregnancy. Unvaccinated people who need MMR should get it before pregnancy or after delivery (CDC advises waiting about 28 days after MMR before trying to conceive).
- If a pregnant person is exposed and not immune, doctors may recommend immune globulin (ready-made antibodies) as post-exposure protection—ask your obstetric and pediatric teams promptly.
- Babies born to someone with measles near delivery need close monitoring. Symptoms can include fever, rash, and jaundice (yellowing), but the rash may be delayed, unusual, or absent.
This is specialist care territory. The parent action is simple: confirm your own measles immunity before pregnancy when possible, keep children’s MMR up to date, and seek care early if exposure or symptoms occur.
What to watch for—and when to seek care
Measles symptoms usually start 7–14 days after exposure: high fever, cough, runny nose, red watery eyes, then a spreading rash. Call your doctor the same day for suspected measles, known exposure without full vaccination, or a newborn whose parent had measles near birth. Seek urgent care for fast or laboured breathing, unusual sleepiness, poor drinking, seizures, or a baby who looks very unwell.
