Projects Antiviral properties of broadly neutralizing HIV-1 antibodies Broadly neutralizing HIV-1 antibodies (bNAbs) can develop in rare infected individuals several years after co-evolution with diversifying viruses. In animal models, passive immunotherapy with potent HIV-1 bNAbs has been shown to protect from infection […] ERC-2013-StG HumAntiViruses Human Antibody Responses to Viruses Adaptive immune responses naturally occurring upon infection or induced by vaccination generate high affinity antibodies, and memory B-cell subsets to respond to further antigenic challenges, providing protection against (re-)infections.
