If a child younger than 9 years of age received one dose of 2009 H1N1 monovalent vaccine and two doses of seasonal influenza vaccine last year, how many doses does the child need this year?
The child will only need one dose of 2010-2011 seasonal influenza vaccine this year. It will provide the 2nd dose of H1N1 and provide protection against 2 other influenza strains (A/Perth/16/2009 (H3N2)-like, and B/Brisbane/60/2008-like) that are expected to be circulating this coming influenza season.
