Measles Returns to London Schools. Vaccines Work When Used.

What Happened

Several schools in London are experiencing measles outbreaks described as "fast-spreading." The BBC reported on cases affecting multiple educational institutions in the city, though specific numbers of affected students were not provided in the headline.

Historical Context

Measles outbreaks in developed countries typically correlate with declining vaccination rates. The UK saw major outbreaks in 2019 (over 1,000 cases) and smaller ones regularly since MMR vaccination rates dropped below the 95% threshold needed for herd immunity. Before vaccines, measles infected 90% of children by age 15. The MMR vaccine is 97% effective after two doses. London has historically had lower vaccination rates than the UK average, particularly in certain boroughs.

What's In Your Control

Whether your children are vaccinated (check their records). Whether you get vaccinated if you're unsure of your status. Avoiding spreading misinformation about vaccines. If you're a parent in London, checking with your school about their vaccination policies.

Does This Require Action?

If you have children in London schools: verify vaccination status and contact your GP if unsure. For everyone else: awareness only. This is a localized public health issue with a well-established solution.
