Percent of human dendritic cells maturing after influenza A antigen loading.

<p>Data are before and after dialysis with 10 and 20% of the initial vaccine or HA amount used so as to reduce any inhibitory effect. The vaccine concentration should not affect maturation; maturation in the presence of vaccine should be similar to the PBS control. The PBS control is also before and after dialysis. Available vaccine was insufficient for testing all four variables for the HA of Hong Kong/G1/99 (H9N2).
