Aandoening
local pain, irritation or discomfort at the injection site (immediately after the injection)=common
uncommon= headache, fever local; enlargement of regional lymph node >1cm. Ulceration with a severe discharging ulcer at the site of injection.
Rare: disseminated BCG complications such as osteitis or osteomyelitis, allergic reactions, including anaphylactic reactions. Local suppurative lymphadenitis, abscess formation.

Uitkomstmaten
Primaire uitkomstmaten
to characterize the anti-mycobacterial immune responses during vaccination with live-attenuated M. bovis BCG Danish strian 1331, in order to provide a framework for using biomarkers in future TB vaccine trials.
Achtergrond van het onderzoek
Tuberculosis is a growing global health problem. The only available vaccine is Bacille Calmette-Querin (BCG). It protects young childeren from severe forms of tuberculosis, but it is of limited value in adults.We hypothesize that the antigen expression profile of BCG during intradermal vaccination is different form that of Mycobacterium tuberculosis. The partial failure of BCG may be related to this difference.
