(CIDRAP News) A World Health Assembly (WHA)committee that took up a resolution to destroy the remaining stocks of smallpox virus failed to reach an agreement today, despite a working group's attempts to find an acceptable solution.
(CIDRAP News) This in-depth article investigates the prospects for development of vaccines to head off the threat of an influenza pandemic posed by the H5N1 avian influenza virus. Its seven parts put advances in vaccine technology in perspective by illuminating the formidable barriers to producing an effective and widely usable vaccine in a short time frame.
(CIDRAP News) The world's last naturally acquired case of smallpox occurred almost exactly 25 years ago, the Centers for Disease Control and Prevention (CDC) notes in today's issue of Morbidity and Mortality Weekly Report.

This difference may be an important reason for the virulence of smallpox and may offer an avenue for research on treatments, they suggest.
