Parasite | Antigen | Priming agent | Boosting agent | Response | Reference |
---|---|---|---|---|---|
Malaria | Circumsporozoite protein of P. berghei | Attenuated fowlpox virus or DNA | MVA | Potent CD8+ T cell responses were elicited in mice with FPV/MVA vaccination. Novel regimen was more protective against challenge than DNA-MVA immunizations. | [7] |
 | P. falciparum surface protein (Pfs25) | DNA | Recombinant protein | Intramuscular injections in rhesus monkeys showed significant increase in transmission blocking antibodies. | [8] |
 | Circumsporozoite protein of P. yoelii | DNA | Pox virus | Immunized neonatal mice showed 93% protection which was CD8+ T cell dependent. | [9] |
 | P. falciparum erythrocyte binding protein | DNA | Recombinant protein | Higher antibody titers and the ability to reduce parasitemia without drug intervention in Aotus monkeys. | [10] |
 | Circumsporozoite protein of P. falciparum | DNA | RTS, S/ASOZA | Malaria volunteers develop P. falciparum specific Abs and Th1 specific CD4+ and CD8+ T cells upon vaccination. | [11] |
Leishmania | Leishmania infantum LACK | DNA | Recombinant vaccinia virus | 60% protection, associated with cell mediated responses, was observed in dogs after challenge compared to controls. | [12] |
 | p36/LACK | DNA | Recombinant vaccinia virus | Vaccination in mice resulted in 70% reduction in lesion size and 1000-fold reduction in parasite loads. | [13] |
 | L. infantum acidic ribosomal protein PO (LiPO) | DNA | Recombinant protein | Boosting elicited stronger IgG2a titers but could not protect against challenge compared to DNA alone. | [14] |
Schistosome | Cu/Zn cytosolic superoxide dismutase (SOD), signal peptide SOD and glutathione peroxidase (GP) | DNA | MVA | DNA vaccines were tested against S. masoni challenge in mice. Boosting with MVA for the same genes had no increased effect expect for mutated GP antigen were boosting lead to 85 % protection. | [15] |
