[Continuing or discontinuing BCG revaccination in adolescents].
BCG revaccination was introduced in Brazil in the mid-90's but no study has evaluated vaccine coverage through direct assessment of the scar. BCG scars were assessed in 2,785 public school adolescents, aged 13 to 14 years, in Southeastern Brazil, between September 2001 and May 2002. The prevalence rate of revaccination was 64.3% (95% CI: 62.5-66.0). Despite the efforts to implement and sustain revaccination, continuing this practice should be reevaluated by public health authorities due to the lack of evidence on its effectiveness.
