Several case-control studies evaluating the effectiveness of BCG vaccine in the last decade have presented contradictory results like previous prospective studies.
Methodological differences could explain some of the case-control study results.
This study explores the possibility that contradictory results could be imputed to the choice of different series of controls.
Three controls were compared for each case of tuberculous meningitis: neighbourhood, hospital and household.
BCG effectiveness estimates were 86.8%, 92.0% and 29.5%, respectively.
