(A) HAI titers to A/CA/07/2009 on days 0 and 28 after a single dose for the subjects that were not seroprotected (initial HAI < 40) at the start of the study. The line on the figure indicates a titer of 40 to show subjects seroprotected post immunization. (B) MN titers to A/CA/07/2009 for individual subjects on days 0 and 28 post immunization.
