The HIV/AIDS epidemic is unfinished business. DNA prime and either protein or recombinant virus boost immunisation studies using antigens expressed at different life-cycle stages of the parasite in an attempt to increase the efficacy of the vaccines. A prime-boost strategy using a novel HIV glycoprotein 120 DNA vaccine was employed to immunize rhesus macaques. Continue if you are OK with this. The first was a recombinant vaccine using a canarypox virus, with inserted genes that code for antigenic proteins from HIV. MVA-BN HIV is a new vaccine candidate, designed for Janssen as part of the development of a prime-boost vaccine regimen with Janssen’s AdVac technology. Another example of a prime-boost protocol in the clinic is the PAVE 100 study, redesigned as HVTN 505. The news follows promising results for one of the two vaccine. To increase antibody production following DNA immunizations, prime-boost regimens have been shown to be an effective approach to induce both humoral and cellular immune responses [35, 36]. To characterize HIV-1 genotypes in candidate populations for a prime-boost phase III vaccine trial in Thai-land, specimens from prevalent and incident HIV-1 infections from a family planning clinic population in Rayong Province and a community cohort in Chon Buri Province, collected from 1998 to 2001, were geno-typed. Heterologous prime-boost vaccination has recently emerged as an effective means of enhancing T-cell responses [6–8], and current research suggests that HIV virus-like particles (VLPs) elicit a superior cellular immune response against HIV in animal models when used as a boost component in a prime-boost strategy [5, 6].
