Public health authorities in both the United States and the United Kingdom are grappling with a significant resurgence of measles, marked by thousands of confirmed cases and a tragic personal story that underscores the critical importance of vaccination. As of April 16, 2026, the U.S. Centers for Disease Control and Prevention (CDC) reported 1,748 confirmed measles cases in the United States this year, with 19 new outbreaks. This alarming trend is mirrored in the UK, where declining vaccination rates have left communities vulnerable.
Rebecca Archer, a mother from Salford, England, recently shared her heartbreaking experience in an opinion piece for The New York Times, highlighting the severe consequences of the highly contagious disease. Her daughter, Renae, contracted measles at just five months old in 2013 during a significant outbreak in Manchester, before she was old enough to receive the measles, mumps, and rubella (MMR) vaccine. Renae tragically died in 2023 at the age of 10 from Subacute Sclerosing Pan-Encephalitis (SSPE), a rare and invariably fatal neurological complication of measles that can emerge years after initial infection. "Parents must realize that refusing vaccinations doesn’t just put your own child at risk. It puts other children at risk," Archer stated in her powerful message.
The UK has seen a substantial increase in measles cases, with 2,911 laboratory-confirmed cases reported in England in 2024, marking the highest annual total since 2012. In 2025, there were 959 cases, and 407 cases were confirmed between January 1 and April 13, 2026. This resurgence is largely attributed to a drop in MMR vaccination coverage, which has fallen below the 95% threshold deemed necessary for achieving herd immunity and preventing widespread outbreaks.
Similarly, the United States, which declared measles eliminated in 2000, is experiencing a concerning rise in infections. The CDC reported 2,288 confirmed cases across 45 jurisdictions in 2025, with 48 associated outbreaks. The decline in vaccination coverage among U.S. kindergartners to 92.5% during the 2024-2025 school year has left approximately 286,000 children vulnerable. Measles is frequently reintroduced into the U.S. by unvaccinated travelers, leading to outbreaks in communities with lower vaccination rates.
Public health officials emphasize that vaccination is the most effective defense against measles, protecting not only vaccinated individuals but also those too young or medically unable to receive the vaccine. The tragic death of Renae Archer serves as a stark reminder of the long-term dangers of measles and the collective responsibility to maintain high vaccination rates to safeguard community health.
