These include inadequate funding for African-led research, equipment and infrastructure challenges, lack of preclinical evaluation capacity, limited manufacturing facilities for clinical-grade vaccines, and a shortage of scientists with specialized laboratory, bioinformatics and biostatistics training. A recently established African-led consortium seeks to strengthen African HIV vaccine contributions by providing support, training and funding to address these gaps by strengthening discovery research and conducting early phase clinical trials of existing and novel Africa-derived vaccine candidates while strengthening African manufacturing infrastructure and capacity.

The formulation of pharmaceuticals with poor solubility is a complex and costly process that hinders overall drug development. Given the limitations of traditional formulation strategies to address these issues, it is essential to explore alternative methods.

To date, three clinical trials have reported either increased anti-HIV-1 neutralizing antibodies or T cell responses following bNAb administration to people living with HIV. Despite strong enthusiasm for this hypothesis, motivated in large part by its potential application to HIV-1 therapeutic strategies, the mechanism(s) underlying a vaccinal ef-fect remain unclear. Moreover, vaccinal effects on antibody and T cell responses are not consist-ently replicated. Partly, this inconsistency may be due to numerous difficulties in sensitively measuring a vaccinal effect in the context of human clinical trials. The magnitude of immune response increase following bNAb administration is generally modest, even when it is observed; a far greater enhancement of neutralization or T cell responses is likely required for a biologically meaningful impact. We review clinical and pre-clinical nonhuman primate studies that evaluated HIV-1/SIV monoclonal antibodies for vaccinal effects, with an emphasis on the strengths and limitations of these studies. Considerations for future studies investigating vaccinal effects are discussed, including appropriate comparators and specificity controls. Lastly, immune response characteristics of elite controller cohorts are outlined as potential vaccinal effect endpoints more likely to mediate HIV-1 suppression. As bNAb therapeutic interventions increasingly turn to combination approaches, including incorporation of immunomodulatory agents, attention to study design incorporating appropriate control groups, and relevant immunogenicity assays will enable more conclusive interpretation of vaccinal effects likely to mediate durable control of HIV.
