title: [Absence of tuberculin reactivity after neonatal vaccination with BCG in Cantabria: analysis of 419 determinations].
abstract: A prospective study is made of the tuberculin test sensitivity at 3 and 12 months after neonatal vaccination with BCG. From the results obtained in 419 tests the conclusion is that the percentage of positive tests is 3.8% and 1.6% at 3 and 12 months respectively, considering the threshold of positivity equal or superior to 10 mm (or 18.9 y 5.6% respectively with the threshold at 5 mm). These results are lower than the ones described previously, and therefore the conclusion is that in Cantabria the tuberculin tests should be valued without taken in consideration the antecedent of previous vaccination with BCG.
