Brief Summary
In the UK, babies receive their vaccinations according to a standard schedule, irrespective of their gestation at birth. This policy is designed so that all babies are protected as early as possible from vaccine preventable diseases such as polio, diphtheria, tetanus, rotavirus, pertussis (whooping cough), Haemophilus influenzae type B, pneumococcal disease and now meningococcal B disease. The 4CMenB vaccination (Bexsero®) was added to the UK schedule in September 2015 and there has been no research looking at whether the vaccine gives the same protection to babies born early as it does to those born at term. The Investigators want to compare two different schedules of 4CMenB and see if one gives better protection to babies born prematurely. It is possible that an extra 4CMenB dose (i.e. three doses in early infancy instead of two) will offer better protection for premature babies. This is what the Investigators are trying to find out through this study.
