Safety and efficacy of combined meningococcal and typhoid vaccine

An authors' error occurred in this short report by Dr S H Koo and others (8 April, pp 908-9). In the table the mean geometric (range) antibody titre to typhoid Vi antigen at 3-6 weeks in group C should have read 1.7 (0.3-45.0) mg/l, not 3.7 (0.3-45.0) mg/l as published. The statistics and conclusions remain the same as this was simply a typographical error.
