Randomized Controlled Trial
Chloroquine for influenza prevention: a randomised, double-blind, placebo controlled trial.
Chloroquine has in-vitro activity against influenza and could be an ideal candidate for worldwide prevention of influenza in the period between onset of a pandemic with a virulent influenza strain and the development and widespread dissemination of an effective vaccine. We aimed to assess the efficacy of such an intervention. ⋯ National Medical Research Council, Singapore.

Tuberculosis is one of the most deadly infectious diseases. The situation is worsening because of co-infection with HIV and increased occurrence of drug resistance. Although the BCG vaccine has been in use for 90 years, protection is insufficient; new vaccine candidates are therefore needed. 12 potential vaccines have gone into clinical trials. ⋯ In the long term, vaccines that prevent or eradicate infection with Mycobacterium tuberculosis would be the best possible option. Improved knowledge of immunology, molecular microbiology, cell biology, biomics, and biotechnology has paved the way towards an effective and safe vaccine against tuberculosis. The pipeline of new vaccine candidates from preclinical to clinical testing could be accelerated by development of biomarkers that can predict the clinical outcome of tuberculosis.
