In a blog by the UK Health Security Agency it is reported that in 2024 there were 2,911 laboratory confirmed measles cases in England, the highest number of cases recorded annually since 2012. Most of these cases were in unvaccinated children under the age of 10. The agency further reports that more than 1 in 10 eligible children under the age of 5 have not had the Measles Mumps and Rubella (MMR) vaccine or are only partially vaccinated, indicating a decline in vaccination rate over the last 15 years. ‘Vaccinations remain the best defence against infection, so it is very important that children attend their routine vaccination appointments and catch up on any they may have missed.’
