Evalution of Tuberculin Skin Test Four Months after BCG Vaccination at Birth

Tuberculin skin reactivity four years after neonatal BCG vaccination.

Two hundred and sixty one of 279 (93.5%) children known to be tuberculin positive shortly after receiving their neonatal BCG vaccination were still tuberculin positive at age 4 years. The results confirm the continuing effectiveness of neonatal BCG at 4 years.

BCG vaccination and the tuberculin skin test

The immune response induced by vaccination with Bacille Calmette-Guérin (BCG) is not fully understood, and the interpretation of the tuberculin skin test (TST) is still under debate. This thesis was based on questions raised while implementing protective measures for healthcare workers and others at risk of exposure to tuberculosis (TB) in Sweden, a country where the prevalence of TB is low. Th...

Tuberculin response in preterm infants after BCG vaccination at birth.

A total of 101 preterm infants between 26 and 37 weeks' gestation who received BCG vaccination at birth were evaluated between two and four months after vaccination. Altogether 32% of these infants had no visible BCG scar. All infants were then tested with tuberculin purified protein derivative (PPD) but only 70 returned for the test to be read 48-72 hours later. The test was negative in 22 (31...

Atypical mycobacterial infection, starvation and effect of BCG vaccination on tuberculin skin test.

Pulmonary manifestations of systemic lupus erythematosus (SLE) include acute lupus pneumonitis, chronic interstitial pneumoni-tis, diaphragmatic dysfunction, atelectasis, pulmonary vascular disease, upper airway dysfunction, and bronchiolitis obliterans. 1 Pneumonia due to infection also develops because infection is a major cause of death of patients with SLE. 2 3 Here, we report a patient wit...

Tuberculin Skin Test Distribution following a Change in BCG Vaccination Policy

BACKGROUND Epidemiologic data regarding tuberculin skin test (TST) responses are an important basis for TB control strategies. This study analyzed TST responses in Korea, which experienced a rapid change in BCG vaccination status. METHODS TST responses in young adults were examined over 5 years. Participants with active TB lesions were excluded. RESULTS A total of 5,552 participants were en...
