PfSPZ Vaccine information

PfSPZ Vaccine is a metabolically active non-replicating whole sporozoite (SPZ) malaria vaccine being developed by Sanaria against Plasmodium falciparum (Pf) malaria. Clinical trials have been safe, extremely well tolerated and highly efficacious. The first generation PfSPZ product is attenuated by gamma irradiation; the second generation vaccines PfSPZ-CVac and PfSPZ LARC2 are, respectively, attenuated chemically and genetically. Multiple studies are ongoing with trials of the PfSPZ vaccines. All three products are produced using the same manufacturing process. These products are stored and distributed below -150 °C using liquid nitrogen (LN2) vapor phase (LNVP) freezers and cryoshippers.
