Freeze-drying formulations #4 and #5 effectively protected adenovirus vaccine activity. The infectivity of recombinant adenovirus vaccines (Ad5-ENV) protected by different formulations was detected post lyophilization. The titer is detected by 293A cells. A Image showing titers of adenovirus in four formulations post lyophilization. The titers of vaccines in FR4 and FR5 were higher than those in PBS (***P < 0.001). B–C The protection of Ad5-ENV stored at 4 °C (B) or 25 °C (C) for 7/14/28 days post lyophilization. The titers of vaccines in FR4 and FR5 are higher than that in FR1.
