New RSV vaccine immunogenicity improved with protein engineering

Key clinical point: New respiratory syncytial virus vaccine candidate DS-Cav1 has greater immunogenicity than previous candidates.

Major finding: Epitope-neutralizing activity is 5-10 times greater 12 weeks after baseline with a 50 mcg or 150 mcg with and without alum adjuvant.

Study details: The findings are based on a prespecified interim analysis of 90 healthy adult participants in a phase 1, randomized, trial of DS-Cav1.

Disclosures: The research was funded by the National Institutes of Health and the Bill & Melinda Gates Foundation. Several authors are inventors on patents for stabilizing the RSV F protein.
