Intanza, from Sanofi-Pasteur MSD, is the first flu vaccine to be administered into the dermal layer of the skin. It is licensed for use only in adults.
Intanza joins the previously launched vaccines Agrippal, Begrivac and Fluvirin (Novartis), Enzira (Wyeth), Fluarix (GlaxoSmithKline), Imuvac and Influvac (Abbott Healthcare).
All of these contain A/California/7/2009 and A/Perth/16/2009 as their H1N1 and H3N2-like components, respectively, in line with WHO recommendations for the 2010/2011 season. The influenza B component in the vaccines (B/Brisbane/60/2008) remains unchanged.
Viroflu (Crucell) is no longer available.
