Immunogenicity of reduced dose priming schedules of serogroup C meningococcal conjugate vaccine followed by booster at 12 months in infants: open label randomised controlled trial

This research paper (BMJ 2015;350:h1554, doi:10.1136/bmj.h1554) contains two errors. In figure 1 the number of participants who were allocated to the control group should say 66, not “165” as was published. Furthermore, in table A in appendix 1 (the data supplement) the column listing the power for the secondary comparison (not reported in current paper) should read 0.88, not “0.95.”
