Measles Makes a Comeback: Why Vaccines Matter

Measles, once thought to be under control in the U.S., is making a worrying return.

The country had declared measles eliminated in 2000, meaning the virus wasn't spreading continuously. But now, cases are rising, with numbers reaching as high as 2,242 in 2025. This isn't just about statistics; it's a sign that measles could become a constant threat again, putting vulnerable people at risk.

Health Officials Spring into Action

When measles pops up, health officials spring into action. They track down where the virus might have spread, like schools or stores, and warn the public. The goal is to stop the virus in its tracks. Doctors and health departments work together to confirm cases and notify people who might have been exposed.

The Seriousness of Measles

Measles is no joke. It can lead to serious problems like:

• Brain swelling
• Pneumonia
• Even death

The good news is that the MMR vaccine is highly effective, with two doses offering 97% protection. But if someone gets measles, the costs add up quickly. In 2025, one case cost around $60,000 in medical care and lost productivity.

Steps to Stay Safe

If you're exposed to measles, there are steps you can take to stay safe:

• Vaccinated or born before 1957: Likely protected.
• Immunocompromised: Contact your healthcare team. They might give you a treatment called IVIG, which can prevent measles if given within six days of exposure. You'll also need to watch for symptoms and quarantine for 28 days to avoid spreading the virus.

The MMR vaccine can also be given within three days of exposure, but only to certain people. If you're unvaccinated and choose not to get the vaccine, you'll have to quarantine for 21 days. Alternatively, you can get IVIG within six days of exposure and quarantine for 28 days.

The Power of Vaccines

Vaccines are a shared responsibility. When enough people in a community are vaccinated, it creates herd immunity, protecting those who can't be vaccinated. So, getting vaccinated isn't just about personal health; it's about protecting others too.
