An outbreak of a virulent form of meningitis in Kent that resulted in two fatalities and hospitalized nearly a dozen individuals has spurred discussions regarding the effectiveness of the UK’s vaccination program.

Officials from the UK Health Security Agency revealed that the strain responsible for the widespread infections in Canterbury was meningitis B, also known as menB. This particular strain had been spreading within the student community at the University of Kent, prompting contact tracing efforts after the deaths of a 21-year-old student and an 18-year-old local sixth form pupil named Juliette, whose passing left her family profoundly distraught.

Meningitis B, the most prevalent type of bacterial meningitis, accounts for about 80% of invasive cases within the bacterial spectrum, which includes strains A, C, W, X, Y, and Z. While vaccines are available for most strains, the MenB vaccine, introduced in 2015, has significantly reduced infections by approximately 75% in vaccinated individuals.

Nevertheless, the MenB vaccine is primarily administered to infants, leaving older individuals who were not immunized post-adolescence when the vaccine was first introduced, unless privately obtained. Calls have intensified for expanding the vaccination program to include teenagers, particularly students who are deemed a high-risk group, as it could prevent severe infections.

Dr. David Elliman, Honorary Associate Professor in Child Health at UCL GOSH Institute of Child Health, emphasized that unlike other vaccines targeting meningitis strains, the MenB vaccine does not effectively prevent germ carriage or offer long-lasting protection. He suggested that the cost-effectiveness and overall benefits of the MenB vaccine should be carefully evaluated before considering wider implementation, with potential consideration for alternative vaccine development.
