Mycobacterium bovis bacillus Calmette-Guérin (BCG), which elicits a degree of protective immunity against tuberculosis, is the most widely used vaccine in the world. Due to its persistence and immunogenicity, BCG has been proposed as a vector for vaccines against other infections, including HIV-1. BCG has a very good safety record, although it can cause disseminated disease in immunocompromised...

A 17-year-old boy presented with a four-week history of neck pain, difficulty chewing and deviation of his tongue to the right. On examination there was tenderness of the mid-cervical spine and a right XII nerve palsy. A 6 cm lesion was noted over the left deltoid (Figure 1). There was no lymphadenopathy or splenomegaly. Blood tests were normal apart fromESR 44 mm/h andCRP 83mg/L. Cervical spin...

background: although the efficacy of bacillus calmette-guerin (bcg) vaccine in the prevention of tuberculosis has been noted consistently, the use of bcg vaccine is not without risk. in this study we aimed to evaluate immunologically, children with complication of bcg vaccination in north of iran.materials and methods: this case-control study began in 30 jan 2013 and was completed in 2 jul 2015...

Background: Bacillus Calmette ET Guerin (BCG) vaccine, compulsory in endemic areas, remains the only available vaccine for prevention of Tuberculosis (TB) despite its modest protective value. Complications may arise in healthy/ immunocompromized hosts. Methods: Children presenting with BCG vaccine related complications in the form of local/distant complications were enrolled from 2007-2010 at C...

Apart from skin and bone lesions the girl was also had intermittent fever, pallor, irritability, and malnourishment. Her parents gave a history of incomplete healing at the BCG vaccination site...

Mucosal-associated invariant T (MAIT) cells are an innate-like T-cell population involved in anti-bacterial immunity. In human beings, MAIT cells are abundant, comprising ~10% of the CD8(+) T-cell compartment in blood. They are enriched at mucosal sites and are particularly prevalent within the liver. MAIT cells are defined by the expression of a semi-invariant T-cell receptor (Vα7.2-Jα33/12/20...
