Do You Need a Measles Vaccine Booster? Here’s What to Know Amid Rising Outbreaks

As a measles outbreak that began in Texas now appears to have spread to at least four other U.S. states, a pressing question is on many people’s minds:
Should I get a measles vaccine booster?

Measles is a highly contagious airborne virus that can cause severe complications, and in some cases, can even be fatal. Thankfully, it’s preventable — thanks to the MMR vaccine (measles, mumps, and rubella), which is usually given in two doses during childhood.

More than 20 years ago, measles was declared eliminated in the U.S., largely due to widespread vaccinations. But in recent years, vaccine hesitancy and declining immunization rates have paved the way for a dangerous comeback.

In 2024, the CDC reported 285 measles cases nationwide. Just four months into 2025, that number has skyrocketed to 800 confirmed cases — a nearly threefold increase. Alarmingly, 96% of those infected were either unvaccinated or had unknown vaccination status.

If you're unsure about your vaccine history or worried about your immunity, it might be time to consult your doctor about a booster — especially if you're in a high-risk area.
