Optimal age for mass BCG vaccination in England and Wells
In 1955, in England and Wells, for the first time, a mass run-out of schoolchildren at the age of 13 was carried out. Preliminary tuberculin tests were positive in 11 - 40% of children of this age. According to the data for 1955, 3614 patients with pulmonary tuberculosis, 337 with tuberculous meningitis and 1171 with tuberculosis of other organs were registered among children under 14 years of age - a total of 5122 patients. In fact, the incidence of tuberculosis among children is much higher. During a mass X-ray examination of schoolchildren in 1956, out of 66,000 examined, 134 patients with tuberculosis were identified who were not registered and did not suspect their illness.
