(CIDRAP News) – Influenza vaccine over the past few months has provided moderate protection overall but didn't have a significant impact on protecting seniors, a study from the US Centers for Disease Control and Prevention (CDC) revealed today.
(CIDRAP News) – An early assessment of this year's influenza vaccine shows it has provided a "moderate" level of protection at 62% so far this season, the Centers for Disease Control and Prevention (CDC) said today.

(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.
(CIDRAP News) With the second wave of the H1N1 influenza virus now hitting, much of the response toe the pandemic is focused on the development and distribution of an effective vaccine, a project that poses many challenges and uncertainties.
(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.
