Viral Vaccine Development
While the HIV prevalence in Southern Africa continues to increase, one long-term strategy for the control of the pandemic is the development of an HIV/AIDS vaccine. The aim is to make prophylactic HIV/AIDS vaccines that will induce broad, polyfunctional CD4+ and CD8+ T cell responses as well as a wide spectrum of long-lived memory T cells and antibody responses. Our most recent funding (SHIP, MRC) for candidate HIV vaccines supports the development of various novel Env vaccines including DNA and poxvirus vaccine vectors, as well as production in tissue culture and plants and establishment of a SHIV/rhesus monkey model for efficacy evaluation of these novel Env-based vaccine candidates. Current veterinary vaccine projects include a novel bovine ephemeral fever virus vaccine based on lumpy skin disease virus (LSDV). We are also improving LSDV as a veterinary vaccine.
Human Papillomavirus (HPV) projects
HPV is causally associated with cervical cancer one of the most important cancers in Africa. Our present research provides data to support HPV vaccine introduction in South Africa, as well as understanding the factors influencing infection and persistence of HPV. We continue to monitor HPV prevalence in various communities around South Africa to provide baseline data to eventually monitor the impact of HPV vaccination. As HIV and HPV are both the cause of major public health problems in SA, we have a specific interest in the impact of HIV infection on HPV. Novel insight has been gained into the impact of HIV co-infection on HPV transmission and natural history in couples. Our group were the first worldwide to study oral HPV antibodies and to demonstrate cervical T cell responses to HPV. Our research in microbicides and HPV infection detected a significant increase in multiple HPV infections in HIV-1 seronegative women using nonoxynol-9, compared with HIV-1 seronegative women using placebo. We also published the first report showing a negative association of HPV infection with the vaginal microbicide Carraguard. We were one of the first groups to apply next generation sequencing technology to characterisation of HPV, and to show that there are many novel HPV viruses present in the genital tract. To date we have described ten novel HPV types. One of our other interests is the impact of the cervical microbiome on HPV infection.
