title: The WHO Vaccine Trial Registry.
abstract: The WHO Vaccine Trial Registry prospectively registers clinical vaccine studies supported by WHO. Through December 1999, the registry includes 103 studies from 43 countries, with nearly 80% in developing countries. The registry documents an expanding research capacity, with an average of 3.9 new studies per year during 1987-1993, rising to 10.7 per year during 1994-2000. The studies concern a broad spectrum of infectious organisms, including: Clostridium tetani (tetanus), dengue virus, enterotoxigenic Escherichia coli (ETEC), Haemophilus influenzae type b (Hib), hepatitis B virus, measles virus, Mycobacterium tuberculosis, Neisseria meningitidis (meningococcus), poliovirus, respiratory syncytial virus (RSV), rotavirus, Salmonella typhi, Shigella, Streptococcus pneumoniae (pneumococcus), and Vibrio cholerae.
