In response to back-to-back incidents involving government laboratories, a top official at the U.S. Centers for Disease Control and Prevention has resigned, and the agency has assembled a safety board to address concerns that have arisen after workers were potentially exposed to anthrax and H5N1 flu.
Last month, Takeda snagged Japanese approval for its cell-cultured influenza vaccine for H5N1, and it's about to have more space to make it.
At the start of 2014 the Chinese vaccine sector was rocked by the failure of three leading suppliers to obtain good manufacturing practice certification. Sinovac Biotech escaped unscathed from the rule tightening and this week posted a 17% jump in fourth-quarter sales.
The seed strain is often to blame for low yields of vaccines to protect against pandemic flu strains H1N1 and H5N1, but Daiichi Sankyo has now encountered difficulties when processing the vaccine, leaving the drugmaker unable to hit the H5N1 vaccine production target it agreed upon with the Japanese government.
Reports the H1N1 flu virus is circulating in North America have prompted a surge in demand for vaccines in Canada. While health authorities typically welcome increased uptake of flu vaccines, the spike in demand has left parts of the country with dwindling stocks.
Since an FDA advisory panel unanimously recommended GlaxoSmithKline's H5N1 vaccine one year ago, links between the vaccine's adjuvant and narcolepsy have strengthened, and the FDA subsequently delayed approval. Now, though, GSK has received its long-sought FDA approval.
Looking to poultry for warning signs of a possible bird flu threat to humans has proved a success in the past. In 2003, H5N1 swept through Asian bird flu populations, forewarning humans. A dead bird sighting then became a cause for alarm around the world.
University of Maryland researchers are developing a new vaccine against H5N1 avian influenza, also known as bird flu, identified by the World Health Organization as a potentially pandemic virus.
Just more than a year after putting a voluntary moratorium on certain experiments involving the H5N1 avian influenza virus, researchers say the studies should restart.
After a lingering controversy over bioterror fears that kept a study under wraps for months, investigators have revealed how 5 simple genetic "tweaks" could make the virus spread swiftly among humans.
