The MMR vaccine – protecting against measles, mumps, and rubella – is one of the true public health triumphs of the modern era. Here, we explore its history, the impact of these diseases, vital UK statistics, and why you should trust and act on vaccination.
Before the vaccine
Measles in the UK
- Pre-1968 (before measles vaccine introduction), there were hundreds of thousands of cases annually. In 1967 alone, 460,407 suspected cases were reported, with 99 deaths.
- In 1949, there were 307 deaths, reducing to 98 deaths by 1959. Between 1970–1988, even with antibiotics and better living conditions, measles caused an average of 13 acute deaths annually.
Mumps and Rubella
- Pre-1988, mumps commonly affected nearly 85% of school-aged children and led to 1,200 hospital admissions per year in England and Wales; it was the most common cause of viral meningitis.
- Rubella outbreaks were cyclical, and the 1962–65 US–European epidemic caused 11,000 miscarriages, 20,000 newborn deaths, and 20,000 congenital rubella cases. Though UK-specific rubella data is less detailed, the global threat was clear.
Enter the MMR vaccine
The measles vaccine was introduced in the UK in 1968, and combined MMR vaccine rolled out in 1988. This triple vaccine soon achieved ~90%+ coverage, drastically reducing all three diseases.
Vaccination’s lifesaving impact
Measles
- From ~460,000 cases and ~100 deaths in 1967 to ~10,000 cases and 1–2 deaths annually by the late 1980s.
- Between 1968–present, the vaccine prevented 20 million measles cases and 4,500 deaths in the UK.
- Since 2000, only 9 measles-related deaths occurred in England & Wales that were vaccine-preventable.
Mumps & Rubella
- Universal uptake led to sharp reductions in mumps-related hospitalisation and meningitis.
- For rubella, universal childhood immunisation across genders eliminated prenatal exposure risk; congenital rubella is now extremely rare in the UK.
The vaccine works – and it’s safe
Efficacy
According to NHS guidance:
- You have 99% protection against measles & rubella after two doses.
- You have around 88% protection against mumps (with milder symptoms if breakthrough occurs).
Safety
- Common side effects include mild rash, fever, and temporary joint pain.
- Serious adverse reactions – such as anaphylaxis – are extremely rare, and healthcare providers are ready to treat them.
- Crucially, no credible link exists between MMR and autism; the scientific community has repeatedly debunked Wakefield’s fraudulent study.
Concerning vaccination coverage
To maintain herd immunity, WHO and NHS recommend ≥95% coverage for two-dose MMR; yet vaccination rates declined in the early 2000s after the autism scare.
In 2023–24, only 88.9% of 2-year-olds received dose 1, and just 83.9% of 5-year-olds had received the second, which is well below target. Alarmingly, in London, MMR2 coverage in 5‑year-olds was just 73.3%.
These declines have prompted a resurgence of measles in 2023, with 2,911 confirmed cases and at least one child death in 2024 – the highest infection rate since 2012.
Why vaccinating your children matters
- Life-or-death impact: Measles can lead to pneumonia, encephalitis, and death. Mumps can cause meningitis and hearing loss; rubella during pregnancy causes severe birth defects.
- Herd immunity: Vaccinating protects those who can’t, including newborns, immunocompromised people, and pregnant women.
- Community resurgence risk: With sub-95% coverage, outbreaks happen quickly.
- Trust the vaccine: There has been extensive and thorough safety testing worldwide. Millions have been vaccinated in the UK since 1988, and serious adverse reactions are rare.
It’s not too late – even for adults
If you missed the MMR vaccine as a child, it’s never too late. The NHS advises two adult doses, one month apart.
It’s especially recommended if you’re:
-
- Starting university or college
- Travelling abroad
- Planning pregnancy
- Working in health or social care.
Countering vaccine hesitancy
Vaccine hesitancy rose due to misinformation, especially post-COVID. But each year, millions of deaths are prevented globally, and MMR’s success in the UK is undeniable: measles has been nearly eliminated, and mumps and rubella are rare.
NHS frameworks such as Vaccine Damage Payment (£120,000 for proven severe reactions) show there is support in the extremely rare cases.
Why you should have the MMR vaccine
- Before the vaccine: Tens of thousands of infections, hundreds of deaths, serious illnesses common.
- After MMR: Dramatic reduction in disease burden; millions of illnesses prevented, 4,500 measles deaths stopped locally, far more globally.
- Vaccines are safe: Side effects are mostly minor; there is no link to autism; serious issues are vanishingly rare.
- Coverage matters: Under 95% puts us at risk of outbreaks – we’ve already seen the consequences.
- Act now: Get your children fully vaccinated and check your own status. Even as an adult, you can still get protected.
The MMR vaccine is a cornerstone of modern public health – a safe, scientifically proven shield against three serious diseases. The data speaks clearly; high coverage saves lives, prevents suffering, and keeps communities safe. With measles now resurging in parts of the UK, the message is urgent and clear:
✅ Vaccinate your children promptly.
✅ If you’re unsure or unvaccinated, get your doses now.
✅ Trust the science: MMR has decades of success on its side.
Together, we can uphold herd immunity, protect the vulnerable, and ensure measles, mumps, and rubella remain relics of the past.
