Improving influenza vaccine virus selectionReport of a WHO informal consultation held at WHO headquarters, Geneva, Switzerland, 14–16 June 2010	2011-08-08		.txt	text/plain	10006	401	24	• The selection process is highly coordinated and involves continual year‐round integration of virological data and epidemiological information by National Influenza Centres (NICs), thorough antigenic and genetic characterization of viruses by WHO Collaborating Centres (WHOCCs) as part of selecting suitable candidate vaccine viruses, and the preparation of suitable reassortants and corresponding reagents for vaccine standardization by WHO Essential Regulatory Laboratories (ERLs). • The selection process is highly coordinated and involves continual year-round integration of virological data and epidemiological information by National Influenza Centres (NICs), thorough antigenic and genetic characterization of viruses by WHO Collaborating Centres (WHOCCs) as part of selecting suitable candidate vaccine viruses, and the preparation of suitable reassortants and corresponding reagents for vaccine standardization by WHO Essential Regulatory Laboratories (ERLs). The continuing threat posed by avian H5N1, the aftermath of the 2009 H1N1 pandemic, the increased knowledge of influenza, and the development and availability of new technologies provide a timely opportunity to review the complex processes and issues involved in influenza vaccine virus selection and to identify potential areas for improvement.	./cache/cord-335948-qkfxfmxb.txt	./txt/cord-335948-qkfxfmxb.txt
