Over the years, scientists have developed groundbreaking vaccines which have considerably lowered and prevented the unfold of extremely contagious illnesses worldwide.
One such vaccine is the measles, mumps and rubella (MMR) vaccine. In truth, the MMR vaccine is the explanation why measles, mumps and rubella are a lot much less frequent within the United States at the moment.
Below, we’ll clarify what the MMR vaccine is and what it protects in opposition to. We’ll additionally go over the MMR vaccine schedule for kids and adults, potential unwanted side effects and why it’s so necessary to get vaccinated.
What is the MMR vaccine and how does it work?
The MMR vaccine is a live-attenuated vaccine, which implies it comprises a small quantity of weakened measles, mumps and rubella (German measles) viruses. The first vaccines to guard in opposition to measles, mumps and rubella have been developed within the Nineteen Sixties and given as particular person photographs. Then within the Seventies, scientists launched a mixed MMR vaccine to guard in opposition to all three illnesses.
Today, there are two MMR vaccine formulations:
- MMR vaccine – Protects in opposition to measles, mumps and rubella
- MMRV vaccine – Protects in opposition to measles, mumps, rubella and varicella (hen pox), and it’s solely accredited to be used in kids 12 months to 12 years outdated
The MMR vaccine is the recommended formulation by the Centers for Disease Control and Prevention (CDC) as a result of the MMRV vaccine has been related to a barely increased danger for fever and febrile seizures after vaccination. There’s a separate vaccination for defense from varicella.
How the MMR vaccine works
Like all vaccines, the MMR vaccine prompts your immune system and teaches it how you can battle sure germs with out you getting sick. Despite some vaccine myths, a live-attenuated vaccine can’t offer you any of the illnesses it protects in opposition to. Most folks obtain two doses of the MMR vaccine, which maximizes long-term immunity.
How efficient the MMR vaccine is at stopping sickness
According to the CDC, one dose of the MMR vaccine is:
- 93% efficient in opposition to measles
- 72% efficient in opposition to mumps
- 97% efficient in opposition to rubella
Two doses of the MMR vaccine is:
- 97% efficient in opposition to measles
- 86% efficient in opposition to mumps
Because rubella was declared eradicated within the U.S. in 2004, there aren’t many research accessible about how efficient a second dose of MMR is at defending in opposition to rubella.
While it continues to be potential to contract measles, mumps and rubella from an contaminated person even in case you’re vaccinated in opposition to them, it’s extraordinarily uncommon. And in case you do get any of the illnesses, it probably received’t be a critical case or trigger critical issues.

Most individuals who had it recovered with out long-term unwanted side effects. But others skilled long-term unwanted side effects or needed to be hospitalized, and many died from issues of the illness.
Due to the success of the vaccine program, measles was declared eradicated within the U.S. by the yr 2000. Deaths resulting from issues from measles dropped from round 500 annually to a few recorded instances from 2000-2024. However, scientists have seen outbreaks of measles instances within the U.S. in recent times resulting from quite a few components, the largest being vaccine hesitancy.
Data exhibits that about 1 in 5 unvaccinated folks will must be hospitalized in the event that they contract measles. In addition, measles can result in extra extreme points equivalent to pneumonia and encephalitis (swelling within the mind), and statistics have proven that 3 folks out of 1,000 will die, even with the very best care potential. So, it’s necessary to get the vaccine to guard your self from preventable sickness.
And whereas there was an over 99% lower in reported mumps and rubella instances because the Nineteen Sixties because of the MMR vaccine, outbreaks can nonetheless happen, so it’s nonetheless an important a part of the vaccine to maintain you protected.
