The MenB vaccine was added to the UK NHS childhood immunisation programme for babies born on or after 1 July 2015. But it means teenagers and young adults over the age of 11 have not received this jab. However, research suggests the MenB vaccine doesn't necessarily prevent transmission of the infection from person to person, doesn't target all the different B bacteria strains and doesn't provide long-term protection. But UK vaccine experts now say government should consider routinely offering the vaccine to all teenagers at around age 15. Around 10,000 people in the Kent region will have already received jabs, as part of the response to the March outbreak.
