The measles were eliminated in the United States in 2000, meaning that there was no viral spread within the country at the time. However, an outbreak in Texas has raised concern among Americans, especially now that multiple cases have been confirmed in states such as New York, California, and New Jersey. Though countless Americans have been vaccinated with the vaccine known as the “MMR” shot, can you still contract the measles if you’ve been vaccinated?
Below, we have a breakdown of the recent measles outbreak and how to prevent an infection, according to the U.S. Center for Disease Control & Prevention.

What Is Measles?
According to the CDC, measles (also known as rubeola) is a “very contagious” illness. If one person is infected, up to 9 or 10 people nearby can contract it if they are not protected. The CDC notes that the infection spreads quickly through the air when the infected person coughs or sneezes, potentially infecting others in the same room even up to two hours after the infected individual has left.
The symptoms of measles primarily include a red rash, along with a high fever that can reach up to 104°F, coughing, runny nose, and red or watery eyes.
How Many Measles Cases Have Been Reported in 2025?
There have been around 523 measles cases recorded in less than three months, representing the second-highest annual total the country has seen in a decade, only behind 2019, which saw over 1,200 cases. Texas alone has 400 confirmed cases.
The current figure is more than likely an undercount due to delays in states reporting cases to the federal health agency.
What Is the MMR Vaccine?
The MMR (measles, mumps, and rubella) vaccine is administered in two doses. According to the CDC, the vaccine is 97 percent effective in preventing measles, while receiving just one dose provides 93 percent effectiveness in prevention.
Can You Get Measles if You Got the Vaccine?
Yes, it is possible to contract measles even if you’ve been vaccinated, but it is rare, according to the CDC. About 3 out of 100 vaccinated individuals may still get the virus when exposed. However, their symptoms tend to be milder compared to those who have not received the two-dose vaccine.
Is There a Cure for Measles?
No, there is no cure or specific treatment for measles once a person contracts it. Individuals at risk of severe complications may require hospitalization if they become infected.
Both the American Academy of Pediatrics and the Centers for Disease Control and Prevention emphasize that vaccination is the most effective way to prevent measles.
