If the H7N9 influenza virus now circulating in China evolves into a pandemic strain, the world is likely to have great difficulty providing adequate supplies of an effective vaccine in time to blunt its impact, according to a viewpoint article by three experts in the Journal of the American Medical Association (JAMA).

(CIDRAP News) – The US Food and Drug Administration (FDA) yesterday approved the nation's first cell-based flu vaccine, a product from Novartis that uses technology that could help vaccinate more Americans in a pandemic but still has many of the same limitations of older egg-based flu vaccines.

The world needs much better influenza vaccines, but the quest for them faces a formidable barrier: overconfidence about the effectiveness of existing influenza vaccines.
