A concerning drop in vaccination uptake has left over a million teenagers in England without protection against meningitis, recent data reveals. The MenACWY vaccine, targeting four meningitis strains, was introduced in 2015 with a high uptake rate of 82.5% in its first full year. However, uptake has significantly declined, leaving 160,000 teens unprotected in 2025.

The vaccine, effective in reducing the disease by over 90%, is crucial for creating herd immunity. Despite a decrease in prevalence, health experts emphasize the importance of teens receiving the MenACWY jab. Specialists stress that while cases of the covered strains remain low, unvaccinated teenagers are at risk.

Research from Oxford University demonstrates the vaccine’s role in establishing herd immunity across age groups. Lead author Matthew Snape highlights the benefits of immunizing teens, not only protecting them but also reducing the community’s risk of meningitis and sepsis. The MenACWY vaccine’s impact extends beyond individual protection.

Although the vaccine does not cover meningitis B, responsible for recent outbreaks, healthcare professionals stress the urgency of vaccination. Dr. Nelly Ninis describes the low uptake as “terrifying,” emphasizing the severity of meningococcal disease. Ensuring teens receive the MenACWY vaccine remains crucial in safeguarding public health.
