Measles is one of the most contagious diseases out there, yet misinformation about it continues to spread just as fast. Some people think it’s just a mild rash, while others believe vaccines aren’t necessary. The reality? Measles is a serious illness that can have life-threatening complications, and the best way to prevent it is through vaccination. Let’s break down some of the biggest myths about measles and set the record straight with facts based on the latest medical research.
Myth #1: Measles Is Just a Mild Childhood Illness
It’s easy to think of measles as just a fever and a rash that kids get and quickly recover from. But in reality, measles can be dangerous—even deadly. The virus doesn’t just cause a rash; it attacks the immune system, making people more vulnerable to other infections. Complications like pneumonia, encephalitis (brain swelling) and even long-term immune suppression can occur.
According to the World Health Organization (WHO), before the measles vaccine became widely available, the disease killed over 2.6 million people each year. And even today, measles outbreaks still happen, mostly in areas where vaccination rates have dropped.
The CDC recommends two doses of the MMR vaccine—one at 12-15 months and another at 4-6 years. It’s over 97% effective in preventing measles after two doses and plays a huge role in stopping outbreaks before they start.
If you’ve only received one dose of the MMR vaccine, you’re not fully protected. While one dose offers about 93% protection, that still leaves room for risk. The second dose boosts your immunity and gives you the full level of protection needed to keep measles at bay—especially during outbreaks. If you're unsure whether you've had both doses, talk to your health care provider about catching up.
"Measles isn’t just a rash—it can have life-altering consequences. The best way to stay safe is through vaccination," says Torry Pledger, M.D., a primary care physician at Riverside Patriot Primary Care.
Myth #2: The Measles Vaccine Causes Autism
This myth has been around for decades, but let’s be clear: There is absolutely no scientific evidence linking the measles, mumps and rubella (MMR) vaccine to autism. This idea came from a now-disproven 1998 study that was later retracted.
Since then, numerous studies have confirmed that vaccines do not cause autism. The Centers for Disease Control and Prevention (CDC), WHO and countless medical experts all agree—the MMR vaccine is safe, effective and necessary.
"The science is crystal clear—vaccines do not cause autism. They do, however, save lives by preventing dangerous diseases like measles," says Dr. Pledger.
Myth #3: Natural Infection Is Better Than Vaccination
Some believe that getting measles naturally provides better immunity than the vaccine. While it’s true that recovering from measles can result in long-term immunity, it comes at a high cost. The disease itself can be life-threatening, leading to hospitalization, permanent complications or even death.
The MMR vaccine, on the other hand, provides long-lasting immunity without the risks associated with the actual infection. The implications are clear—why take unnecessary risks when there’s a safe way to prevent the disease?
Myth #4: Measles Isn’t That Contagious
Think you have to be in close contact with someone to catch measles? Think again. Measles is one of the most contagious diseases in the world. The virus spreads through the air when an infected person coughs or sneezes and can linger for up to two hours.
If you’re unvaccinated and breathe in those virus particles, you have a 90% chance of getting measles. That’s why it’s so important to get vaccinated—not just for yourself, but to protect those who can’t be, like infants and people with weakened immune systems.
Myth #5: There’s a Cure for Measles
Unfortunately, there’s no magic pill that cures measles. Once someone gets infected, treatment is all about managing symptoms and preventing complications. Health care providers recommend rest, hydration, fever-reducing medications (avoid aspirin in children), and sometimes vitamin A supplements, which can help reduce severity in children.
In severe cases, hospitalization may be necessary, especially if complications like pneumonia or dehydration develop.
Final Thoughts: Stopping Measles Starts with Facts
Misinformation about measles and vaccines puts lives at risk. The truth is, measles is highly contagious, potentially deadly and completely preventable with vaccination.
If you have questions about the MMR vaccine or if you think you or your child has been exposed to the measles, talk to your health care provider right away. The best way to protect yourself and your community is by staying informed and getting vaccinated. Measles isn’t just a problem of the past—it’s a threat we can stop together with science and smart choices.
