Figure 3. Induced protection against H1N1 by the H1N1 vaccine candidates.

Figure 3

Protection of immunized animals (5 or 6 weeks after immunization with AdHA.wt vs Ad5 control or AdHA.cod vs Ad5 control) against an intranasal challenge with 1000 pfu of A/Ohio/7/09 (H1N1)pdm was measured as viral titers in lung and nasal turbinate determined 3 days post-inoculation in a plaque formation assay using MDCK-L cells. Shown are log10 values of mean titer for each group ± SEM. The horizontal dashed line represents the lower limit of detection of the assay.
