Summary

Story summary

Researchers face challenges in developing an HIV vaccine due to the virus's diverse strains and rapid mutations.
A study in Science Immunology reports success in inducing broadly neutralizing antibody (bnAb) precursor B cells in rhesus macaques using an optimized HIV envelope protein.
Both protein-based and mRNA-based vaccines generated strong bnAb precursor B cells.
These findings indicate potential strategies for human vaccine development.
