THIS STUDY IS IN FOLLOW UP
What is the purpose of the study?
Children are at risk of meningitis and septicaemia (blood poisoning) due to a bacteria called meningococcus. Understanding how young people respond to vaccination against this disease may help to protect them in the future. In this study we are seeking to understand the immune response of young people to the 4CMenB vaccine, the vaccine against MenB infection. We are trying to determine if children who received the vaccine as infants and toddlers are still protected from MenB infection as they enter adolescence, and if they have a stronger immune response with just a single booster (“top up”) vaccine than those who have never received the vaccine.
