The present investigation dealswith development and characterization of the liposomes-based freeze-dried rods for the vaginal delivery of gp140 antigen in mice. Positively charged, negatively charged and neutral liposomes were prepared and characterized for various parameters e.g. morphology, size, polydispersity index, zeta potential and antigen encapsulation efficiency. To further improve the efficacy of vaccine delivery, antigen encapsulated liposomes were formulated as polymer gel-based freeze-dried rods,which were then characterized for moisture content. The redispersibility of the liposomes-based freezedried rods was determined in simulated vaginal fluid and liposome gel was investigated for mucoadhesion. The developed liposome-based freeze-dried rods systems could offer potential as stable and practical dosage form for the mucosal immunization against HIV-1 infection.
