From today, around one million people in the UK are eligible to receive the meningitis B vaccine free on the NHS, following concern about meningococcal B infections. The coverage is intended to reduce the risk of serious illness caused by Neisseria meningitidis group B. Sources describe meningococcal B as a potentially life-threatening infection that can lead to complications such as inflammation of the lining of the brain (meningitis) and sepsis, sometimes referred to as blood poisoning. The articles frame the decision as a response to outbreaks and the severity of cases associated with the strain. The reporting does not specify further eligibility details beyond the overall scale of people covered, and it does not provide additional vaccine rollout information such as locations, timing for different groups, or expected uptake. Overall, the information presented focuses on expanded NHS access to the vaccine and the goal of preventing severe outcomes linked to meningitis B.
