Upon passive inhalation of dry influenza vaccine formulations in an optimized set - up , BLP and Advax / BLP adjuvanted formulations induced significantly higher systemic immune responses than the nonadjuvanted formulation .
Remarkably , all vaccinated animals not only survived a lethal influenza challenge ,
Upon passive inhalation of dry influenza vaccine formulations in an optimized set - up , BLP and Advax / BLP adjuvanted formulations induced significantly higher systemic immune responses than the nonadjuvanted formulation .
Remarkably , all vaccinated animals not only survived a lethal influenza challenge , but also did not show any shedding of challenge virus except for two out of six animals in the Advax group .
