Figure 4: Serum H2Nx Neutralization Titers.
Neutralization titers were obtained from select participants’ sera on Day 0 and Day 21. Titers were obtained by taking the geometric mean titer of the replicates for each of the vaccine groups. Serum was tested against seven H2Nx influenza viruses. The mean and standard mean error are shown. The lower limit of detection is 5 while the upper limit of detection is 640.
