Results Published in Clinical Vaccine Immunology Compares AdVAV Favorably Against Only Currently Licensed Alternative
Vaxin Inc., a clinical stage vaccine development company, today announced that a recently published study demonstrated that utilizing a single vaccination with the company’s AdVAVTM intranasal anthrax vaccine performs as well as the currently licensed Anthrax Vaccine Absorbed (AVA; BioThrax®), which requires two vaccinations. AdVAV is administered via an intranasal route rather than the intramuscular route of AVA. Intranasal delivery is generally believed to be a superior vaccination route because the mucosal immune response is important for protection, particularly against respiratory diseases. The study found that protection from aerosolized anthrax after a single dose of AdVAV was no worse than the protection afforded by multiple doses of AVA. Importantly, AdVAV produced protective antibody titers with earlier onset and greater persistence than AVA, suggesting that AdVAV may offer both rapid and long-lasting protection with just a single dose.
