vaccine and other anti-infective challenge studies
|
The drive to develop new prophylactic vaccines has resulted from the increase in impact of emerging diseases, bioterrorism and resistance to existing antimicrobials, as well as the apparent increased virulence of some viruses, such as influenza. Charles River Biopharmaceutical Services (BPS) is working with companies that develop vaccines by providing in vivo challenge studies in addition to its large portfolio of vaccine tests.
Model development involves the deliberate infection of a healthy host, allowing for a greater understanding of the infecting pathogen and the potency/efficacy of a product. Many ethical and safety considerations need to be addressed for such studies, and assessment is dependent on the pathogen, route of administration and host species. Charles River has experience working with antibiotics and antifungals. We have established an experimental model of vaginal candidiasis in rats. Other models can be established upon request. We also have experience with Medical Countermeasures (MCMs), including countermeasures for botulinum toxin in all seven serotypes.
