Baby Vaccine Study (Sched3)

Summary

This multicentre, parallel group, block randomised clinical trial aims to investigate the post booster antibody response in UK infants given a reduced priming schedule of meningococcal serogroup B vaccine and 13 valent pneumococcal conjugate vaccine. It will provide information about how best to include the meningococcal B vaccine (likely to be introduced late 2015) into the routine immunisation schedule. The UK Department of Health provides a routine vaccination schedule for children in the UK and are advised by the Joint Committee on Vaccination and Immunisation (JCVI). The Department of Health have announced that the meningococcal B vaccine (Bexsero) be introduced to the routine schedule as a 2+1 schedule. Cost effectiveness could also be improved by removing the current MenC conjugate vaccine dose given at 3 months of age. There is no published immunogenicity data for Bexsero when given at 2, 4 and 12 months of age (2+1 schedule) and with concomitant Infanrix/IPV/Hib which has now replaced Pediacel in the infant programme. This change to the schedule would result in three injections at 2, 4 and 12 months, and given previous reluctance among parents for three injections at one visit, an option to reduce PCV13 to a 1+1 schedule (priming dose at 3 months and booster at 12 months) will be assessed in this study.
