Abstract

Our results are consistent with China serologic and immunologic data from pre-licensure, controlled trials, which showed that children, adults and old people have good immune responses to H1N1 vaccines.5 Despite the possible limitations in this case-control study, we reveals that the H1N1 vaccine can provide strong protection against reported (or severe), laboratory-confirmed influenza A (H1N1) during October 2009 to February 2010
