Figure 3. Protein and NA content of vaccines and purified viruses.

Figure 3

Panels A, B and C show the total protein, HA titer and NA activity (fluorescence units) of a dose in five years of vaccines. The results in panel B reflect varying sizes and avidities of HA rosettes in the vaccine, since each vaccine contains 15 µg of each of the three HAs (total 45 µg).

Panels D and E show HA titer and NA activity of some of the viruses that were contained in the vaccines used in A–C. Results were calculated per 45 µg of HA for comparison with A–C.
