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) has approved the first influenza vaccine produced with the help of an insect virus and recombinant DNA technology, an approach the agency says may make it possible to start production faster in the event of a flu pandemic.
(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.
(CIDRAP News) German authorities investigating a possible sprout link to a large Escherichia coli outbreak said today that lab samples are negative so far, dashing hopes for a quick end to the investigation and adding more confusion to the search for the source.
(CIDRAP News) Researchers from the University of Michigan say one measure of flu vaccine efficacy that has been used in a number of past controlled trials is not very accurate, and that this may have led to a degree of overselling of the protection the vaccines provide.
(CIDRAP News) The US Centers for Disease Control and Prevention (CDC) today released newer, more precise estimates of the foodborne illness burden, suggesting 1 in 6 Americans get sick each year, a rate lower than previously thought.
(CIDRAP News) Ending months of delay, a large bipartisan majority in the US Senate today passed a bill that aims to make the nation's food supply safer by giving the Food and Drug Administration (FDA) more authority over food producers and requiring large producers and processors to develop detailed food safety plans.
(CIDRAP News) A new report says that a cell culture derived influenza vaccine and a conventional egg-based vaccine both proved effective in a large international clinical trial, offering support for those who contend that cell-based vaccines should become an important part of flu vaccine supplies in coming years.
