Can You Get Measles Twice? Myths and Facts Explained

Measles is a highly contagious viral infection that can cause serious health complications, particularly in young children and unvaccinated individuals. With recent outbreaks in various parts of the world, many people have concerns about the disease, how it spreads, and whether it can return after infection. At Bourne End Pharmacy Travel Clinic, we believe in helping our community stay informed and safe while in the UK and travelling the world, so we’re addressing common myths and facts about measles, including the question: can you get measles twice?

Myth 1: Measles is Just a Harmless Childhood Illness

Fact: Measles can lead to serious complications, even in healthy individuals.

While some people assume measles is just a minor childhood illness, it can have severe consequences. The virus weakens the immune system, making individuals more susceptible to infections like pneumonia, ear infections, and encephalitis (swelling of the brain). In rare cases, measles can even lead to long-term complications such as subacute sclerosing panencephalitis (SSPE), a fatal brain disorder that can develop years after infection.

Myth 2: You Can Get Measles More Than Once

Fact: Most people develop lifelong immunity after having measles once.

The body’s immune system responds to measles by creating long-term immunity. Once someone has recovered from the virus, their immune system remembers how to fight it if they are exposed again. However, there are rare cases where a person with a weakened immune system may not retain full immunity, leaving them susceptible to reinfection.

For the vast majority of people, having measles once means you won’t get it again. That said, vaccination is the safest way to gain immunity without risking severe complications.

Myth 3: The Measles Vaccine Doesn’t Work

Fact: The MMR vaccine is highly effective and provides long-term protection.

The measles, mumps, and rubella (MMR) vaccine is one of the most effective vaccines available. It provides around 97% protection against measles when both doses are administered. This vaccine has significantly reduced measles cases worldwide, preventing thousands of deaths and hospitalisations every year.

If everyone eligible gets vaccinated, herd immunity protects those who cannot receive the vaccine due to medical reasons, such as infants or people with certain immune conditions.

Myth 4: Only Children Need to Worry About Measles

Fact: Adults who are unvaccinated can also contract measles and experience complications.

Measles is not just a childhood illness—anyone who has not been vaccinated or previously infected is at risk. In recent years, outbreaks have occurred in adults who were either never vaccinated or only received one dose of the MMR vaccine instead of the recommended two.

Adults who catch measles often experience more severe symptoms and complications compared to children, including pneumonia and encephalitis. If you’re unsure about your vaccination status, contact Bourne End Pharmacy for advice.

Myth 5: The Measles Vaccine Causes Autism

Fact: There is no scientific link between the MMR vaccine and autism.

This harmful myth originated from a now-debunked and retracted study that falsely claimed a connection between the MMR vaccine and autism. Extensive research from around the world has found no link between vaccines and autism. The spread of this misinformation has led to reduced vaccination rates, resulting in outbreaks of preventable diseases like measles.

The MMR vaccine is safe, effective, and strongly recommended by medical professionals worldwide.

Myth 6: Measles Is No Longer a Threat

Fact: Measles cases have been rising in the UK and abroad, particularly due to lower vaccination rates at home.

While measles was once considered eliminated in many developed countries, cases have been rising due to vaccine hesitancy. Measles is one of the most contagious diseases, and even a small decline in vaccination rates can lead to outbreaks.

According to health authorities, a 95% vaccination rate is needed to maintain herd immunity and prevent outbreaks. If fewer people get vaccinated, measles can return, putting vulnerable groups at risk.

While many are vaccinated in the UK, the risk of encountering MMR on your travels is more likely – this is why it is one of our key travel vaccines.

Myth 7: You Don’t Need the MMR Vaccine If You’ve Already Had One Dose

Fact: Two doses of the MMR vaccine provide the best protection.

While one dose of the MMR vaccine offers about 93% protection, the second dose increases immunity to around 97%. This is why the NHS recommends two doses—one given at around 12-15 months of age, and the second before a child starts school, around 3-5 years old.

Adults who missed their second dose as children can still get vaccinated. If you’re unsure about your vaccine status, Bourne End Pharmacy can provide guidance.

Myth 8: Natural Immunity is Better Than Vaccine-Induced Immunity

Fact: The risks of catching measles far outweigh any potential benefits of natural immunity.

While it’s true that having measles once usually provides lifelong immunity, the dangers of the disease make this a risky approach. Measles can cause severe illness, hospitalisation, and long-term complications, which can be avoided through safe vaccination.

Getting the MMR vaccine provides strong immunity without the risk of severe illness or complications.

How to Protect Yourself and Your Family

– Ensure you and your children are fully vaccinated with both doses of the MMR vaccine.

– Check your vaccination records if you are unsure about your immunity.

– Be aware of measles symptoms, such as fever, cough, rash, and red eyes, and seek medical advice if needed.

– Avoid close contact with infected individuals if there is a local outbreak.

– Encourage friends and family to stay informed and vaccinated.
