Vaccine Discovery,
Development and
Bioanalytical Services

Nonclinical toxicological and safety assessment are vital components of the regulatory pathway for vaccine research and development. Critical decisions such as human dose, route of administration and frequency of clinical dosing are informed by preclinical vaccine immunogenicity, efficacy and safety data.

Aragen Life Sciences, with a legacy spanning over 25 years, offers complete nonclinical evaluations, designed around the toxicological concerns that are unique to your vaccine. Aragen has been a preferred partner to some of the world’s largest vaccine manufacturers since 1996.

The Aragen Advantage:

• OECD GLP compliant and AAALAC Accredited Facilities
• DABT and ACVP board-certified toxicologists and pathologists
• Comprehensive vaccine studies from acute and chronic toxicology to reproductive toxicology
• Extensive experience with live attenuated, recombinant, nucleic acid and VLP vaccines
• Data accepted by regulatory agencies in India, Africa, Europe, Thailand and Australia
• All in-life, bioanalytical, pathology and histopathology are performed at Aragen
• Highly experienced bioanalytical team skilled in both chemistry and biology
