Measles: What You Need to Know and How to Protect Yourself

Measles is more than just a childhood rash—it's a serious, highly contagious disease that can lead to severe health complications. Although largely eliminated in the U.S. thanks to vaccination, outbreaks still occur, especially when vaccination rates decline. Here's what you need to know.

What Is Measles?

Measles is a viral illness known for its red rash and high fever, but it’s much more than a temporary nuisance. The virus spreads through the air when an infected person coughs or sneezes, and it can linger in the air for up to two hours.

Symptoms usually appear 7–14 days after exposure and include:

• High fever (often over 104°F)

• Cough

• Runny nose

• Red, watery eyes

• Tiny white spots in the mouth (Koplik spots)

• A full-body rash that typically starts on the face

Why Is Measles Dangerous?

While most people recover, measles can lead to:

• Pneumonia

• Brain swelling (encephalitis)

• Permanent hearing loss

• Death (especially in young children and people with weakened immune systems)

  
  
  
  

How to Protect Yourself: The MMR Vaccine

The MMR vaccine (Measles, Mumps, and Rubella) is the best protection against measles. According to the CDC Vaccine Information Sheet (VIS):

• One dose is about 93% effective

• Two doses are about 97% effective

Who Should Get It?

1. Children typically receive the first dose at 12–15 months and the second dose at 4–6 years.

2. Teens and adults who haven’t been vaccinated or aren't sure should speak to their doctor.

3. International travelers should ensure they’re fully vaccinated

Is the Vaccine Safe?

Yes. The MMR vaccine has been used for decades and has a strong safety record. Mild side effects like a sore arm or low fever may occur. Serious side effects are extremely rare. Several large studies have PROVEN that it DOES NOT cause or link to autism. This has been thoroughly debunked. Anything saying otherwise is "pseudoscience" and NOT TRUE.

Final Thoughts

Vaccination doesn’t just protect you—it helps safeguard entire communities, especially those who can't get vaccinated due to health conditions. If you’re unsure about your vaccination status or have questions, talk to your healthcare provider.
