Plain English Summary
Background and study aims
Meningitis (infection of the lining of the brain) and septicaemia (blood poisoning) have many causes; an important cause in the UK is a bacteria called Meningococcus. Vaccination protects against some forms of Meningococcus by encouraging the body to make antibody to the bacteria - a chemical which helps fight the bacteria if it is encountered. In the UK babies are vaccinated according to the same schedule whether they are born early (preterm) or on time, but there are concerns that preterm babies may not respond as strongly to their vaccinations - this may result in less protection. In 2015 a new vaccine, the Men B vaccine, was introduced. There have been no studies done to determine whether this will work as well in preterm babies compared with term babies. This study will compare responses made by babies who are vaccinated according to two different schedules. This could help doctors make decisions about what programme should be followed for preterm babies.
Who can participate?
Premature babies born before 35 weeks of pregnancy
What does the study involve?
Parents are approached about the study and provided with information. If parents wish their baby to take part in the study they are asked to sign a consent form. Babies are randomly allocated to receive their Men B vaccine (Bexsero) according to one of two schedules - they either receive two doses of Men B vaccine at 2 and 4 months or three doses of Men B vaccine at 2, 3 and 4 months alongside their routine vaccinations given according to the UK schedule. Parents are asked to complete a diary card for one week following each set of vaccinations. Blood sampling is performed at 5, 12 and 13 months. These blood samples are to measure the amount of antibody (a protein which fights infection) following Men B vaccination to compare the two schedules to see if one gives better protection to babies born preterm.
What are the possible benefits and risks of participating?
If, after the booster vaccination, the baby is found to have a low response to vaccination they are offered an additional booster vaccine. This study involves the administration of vaccines which are given as part of the routine vaccination schedule. Whilst all vaccinations carry a very small risk of adverse reactions this is not greater for those taking part in the study compared with those receiving the vaccinations as part of routine care and all vaccines given as part of the study are given by members of staff trained in vaccine administration and the management of adverse reactions. The study involves blood samples being obtained which can be associated with discomfort and bruising, but these samples will be collected by staff who are trained in obtaining blood samples from babies and local anaesthetic cream can be used for the blood sampling.

Condition
Meningitis
Intervention
Babies will be randomised in a 1:1 ratio to receive two doses (at 2 and 4 months) or three doses (at 2, 3 and 4 months) of Men B vaccine (Bexsero) in their primary vaccination series. All babies will receive their other routine vaccinations according to the UK schedule which will include a booster dose of Men B vaccine (Bexsero) at the age of 12 months.

Primary outcome measure
Antibody response to Men B vaccination assessed using serum bactericidal antibody (SBA) assays performed on samples collected at 5 months (post primary), 12 months (pre-booster) and 13 months (post booster):
1. hSBA GMTs 1 month after completion of primary immunisations for relevant Bexsero antigens: fHbp, NadA and PorA
2. hSBA proportions ≥1:4, at 1 month after completion of primary immunisations for relevant Bexsero antigens: fHbp, NadA and PorA
Secondary outcome measures
Local and systemic effects of the vaccine collected using a diary card completed for the 7 days following each set of vaccinations:
1. The percentage of infants presenting with fever, local reactions and non-febrile systemic reactions within the 7 days following each Bexsero® vaccine dose
2. The percentage of inpatients who have a change/deterioration in cardiorespiratory status within the 72 hours following each Bexsero® vaccine dose
3. The percentage of infants investigated for sepsis and commenced on antibiotics within 7 days of Bexsero® vaccination
4. hSBA GMTs at 12 months of chronological age (pre booster) for relevant Bexsero® antigens: fHbp, NadA and PorA
5. hSBA proportions ≥1:4, at 12 months of chronological age (pre booster) for relevant Bexsero® antigens: fHbp, NadA and PorA
6. hSBA GMTs at 13 months of chronological age (4-6 weeks post booster) for relevant Bexsero® antigens: fHbp, NadA and PorA
7. hSBA proportions ≥1:4, at 13 months of age (post booster) for relevant Bexsero® antigens: fHbp, NadA and PorA
