Complementary protein prime‐rNDV‐L‐gag boost vaccination results to a vigorous protection in the airway. CxB6 F1 mice were vaccinated as indicated in (a) and the x‐axis of (b) then challenged 12 weeks after the last boost. In a weight loss was monitored daily for 7 days and lung virus titer determined as previously reported 22, 23, 25, 26. (b) Mean ± SD lung virus titers (PFU/ml) of three repeat experiments are shown (*p = 0.02, **p = 0.04, ***p = 0.05, p = 0.08 ns, notsignificant (two tailed t test).
