Manter ou suspender a revacinação BCG em adolescentes

Abstract

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.

Path of infectious diseases in Brazil in the last 50 years: an ongoing challenge

“…More recently, analyses on the high social impact of TB and estimates of its treatment costs 49 , new approaches to its surveillance 161 , and one pioneering study that analyzed the effectiveness of revaccination strategy of adolescents with BCG 35 were published.…”
