Clinical Scorecard: Sustained Efficacy of AAV Vector-Based SARS-CoV-2 Prevention in Murine Models and Non-Human Primates

At a Glance

CategoryDetail
Condition
Key MechanismsRecombinant adeno-associated virus (rAAV) delivery of neutralizing antibodies (source needed).
Target Population
Care Setting

Key Highlights

  • Single intramuscular administration of rAAV-P2C5-Fc provides long-term protective efficacy against SARS-CoV-2 variants (source needed).
  • Antibody levels remained protective for over 480 days in mice and up to 1,120 days in marmosets (source needed).
  • Biodistribution analysis showed minimal off-target spread of rAAV (source needed).
  • Moderate anti-AAV capsid antibody responses were detected; anti-drug antibodies against P2C5-Fc remained undetectable (source needed).
