Geometric Mean and Standard deviations for the end-point microneutralization titers of three vaccine groups against diverse H5N1 virus strains.

aMN Data are shown for post-H5N1 vaccination sera collected on day 21 following single H5N1 booster vaccination from the MF59-adjuvanted primed and nonadjuvanted primed or after two vaccinations in the unprimed control vaccine group.bPercentage of responders (fraction of subjects) demonstrating MN titers of ≥1∶40 are shown in the parenthesis.
