3Rs implementation in veterinary vaccine batch-release testing: Current state-of-the-art and future opportunities. A...

Area of Science:

• Veterinary Medicine
• Toxicology
• Vaccinology

Background:

• Regulatory authorities mandate veterinary batch-release testing for vaccine potency and safety.
• Traditional testing methods heavily rely on laboratory animals, posing ethical and practical challenges.
• Advancements in vaccine research present opportunities to replace in vivo testing with alternative methods.

Purpose of the Study:

• To outline the state-of-the-art non-animal approaches for veterinary batch-release testing.
• To discuss the implementation of the 3Rs (Replacement, Reduction, Refinement) in quality control.
• To identify barriers and opportunities for advancing alternative methods in veterinary vaccine testing.

Main Methods:

• A three-part event series (two webinars, one workshop) was organized.
• The events focused on the state-of-the-art non-animal approaches for veterinary batch-release testing.
• Discussions included the deletion of obsolete safety testing and current stakeholder initiatives in Europe, North America, and Asia-Pacific.

Main Results:

• The events fostered a better understanding of barriers to implementing the 3Rs in veterinary vaccine testing.
• Participants identified the need for open communication, collaboration, and international regulatory harmonization.
• Commitments were shared by represented countries to advance the acceptance of alternative methods.

Conclusions:

• Accelerating the acceptance of non-animal testing methods requires concerted efforts in communication and harmonization.
• Stakeholder collaboration is crucial for overcoming challenges in implementing the 3Rs for veterinary vaccines.
• There is a global commitment to advancing alternative methods, despite existing implementation barriers.
