Meningococcal bacterial are an important cause of meningitis and septicaemia in the UK. There are several strains of these bacteria and vaccines are available to protect against infection caused by some, but not all, strains.
In the UK, babies are vaccinated according to the same schedule whether they are born early (preterm) or on time. However, there are concerns that preterm babies may not respond as strongly to their vaccinations and this may result in less protection. In 2015 a new meningococcal group B (Men B) vaccine was introduced into the routine immunisation schedule. As yet, there is no evidence as to whether this will work as well in preterm babies compared with babies born on time. This project will compare responses made by babies who are vaccinated according to two different schedules and could help inform decisions about what programme should be followed for preterm babies.
What the research team will do
The research team will recruit 136 preterm babies. They will randomly assign these babies to one of the two study groups; with one group receiving a Men B vaccine at 8 weeks and 16 weeks of age (the current UK schedule for Men B in term babies) and the other group receiving an additional dose at 12 weeks. Blood tests will be obtained over the study period to check the babies’ antibody levels. The research team will also ask parents/caregivers to keep a record of any reactions that occur after their babies’ vaccinations.
This project is being partially funded by Meningitis Now. Other funding is being provided by GSK.
How this project will help us fight meningitis
This project could help us to determine what vaccination programme should be followed for preterm babies to help protect them against meningococcal disease.
This 30-month project started in April 2017.
