Protein antigens, such as HIV envelope protein, require adjuvants for high immunogenicity. Here the authors show that a combined adjuvant approach with slow antigen delivery and potent ISCOMs adjuvant primes robust germinal center activity and humoral immunity in non-human primates. pSer-modified antigen shifts immunodominance to allow subdominant epitope-targeting of rare B cells.
