Abstract
Potency controls of inactivated rabies vaccines for human use are confirmed by the National Institutes of Health challenge test in which lethal infection with severe neurological symptoms should be observed in approximately half of the mice inoculated with the rabies virus. Weight loss, decreased body temperature, and the presence of rabies-associated neurological signs have been proposed as humane endpoints. The potential for reduction of animal suffering by introducing humane endpoints in the potency test for inactivated rabies vaccine for human use was investigated. The clinical signs were scored and body weight was monitored. The average times to death following inoculation were 10.49 and 10.99 days post-inoculation (dpi) by the potency and challenge control tests, respectively, whereas the average times to showing Score-2 signs (paralysis, trembling, and coma) were 6.26 and 6.55 dpi, respectively. Body weight loss of more than 15% appeared at 5.82 and 6.42 dpi. The data provided here support the introduction of obvious neuronal signs combined with a body weight loss of ≥15% as a humane endpoint to reduce the time of animal suffering by approximately 4 days.

Report on the international workshop on alternatives to the murine histamine sensitization test (HIST) for acellular pertussis vaccines: state of the science and the path forward. Biologicals 2014; 42:114-22. [PMID: 24394373 DOI: 10.1016/j.biologicals.2013.11.011] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2013] [Revised: 11/06/2013] [Accepted: 11/29/2013] [Indexed: 11/20/2022] Open
Abstract
Regulatory authorities require safety and potency testing prior to the release of each production lot of acellular pertussis (aP)-containing vaccines. Currently, the murine histamine sensitization test (HIST) is used to evaluate the presence of residual pertussis toxin in aP containing vaccines. However, the testing requires the use of a significant number of mice and results in unrelieved pain and distress. NICEATM, ICCVAM, their partners in the International Cooperation on Alternative Test Methods, and the International Working Group for Alternatives to HIST organized a workshop to discuss recent developments in alternative assays to the HIST, review data from an international collaborative study on non-animal alternative tests that might replace the HIST, and address the path toward global acceptance of this type of method. Currently, there are three potential alternative methods to HIST. Participants agreed that no single in vitro method was sufficiently developed for harmonized validation studies at this time. It is unlikely that any single in vitro method would be applicable to all aP vaccines without modification, due to differences between vaccines. Workshop participants recommended further optimization of cell-based assays under development. Participants agreed that the next international collaborative studies should commence in 2013 based on discussions during this workshop.

Abstract
Routine potency testing of Leptospira vaccines is mostly conducted using a vaccination-challenge test that involves large numbers of hamsters and unrelieved pain and distress. NICEATM, ICCVAM, and their international partners organized a workshop to review the state of the science of alternative methods that might replace, reduce, and refine the use of animals for veterinary Leptospira vaccine potency testing and to identify ways to advance improved alternative methods. Vaccine manufacturers were encouraged to initiate or continue product-specific validation using in vitro enzyme-linked immunosorbent assays as replacements for potency testing of four common Leptospira serogroups. Participants discussed the potential for eliminating the back-titration procedure in the hamster challenge assay, which could reduce animal use by 50% for each individual potency test. Further animal reduction may also be possible by using cryopreserved Leptospira stock to replace continual passaging through hamsters. Serology assays were identified as a way to further reduce and refine animal use but should be considered only after attempting in vitro assays. Workshop participants encouraged consideration of analgesics and use of earlier humane endpoints when the hamster vaccination-challenge potency assay is used. International harmonization of alternative potency methods was recommended to avoid duplicative potency testing to meet regionally different requirements.

Abstract
NICEATM and ICCVAM convened an international workshop to review the state of the science of human and veterinary vaccine potency and safety testing methods and to identify opportunities to advance new and improved methods that can further reduce, refine, and replace animal use. Six topics were addressed in detail by speakers and workshop participants and are reported in a series of six reports. This workshop report, the second in the series, provides recommendations for current and future use of non-animal methods and strategies for veterinary vaccine potency testing. Workshop participants recommended that future efforts to replace animal use give priority to vaccines (1) that use large numbers of animals per test and for which many serials are produced annually, (2) that involve significant animal pain and distress during procedures, (3) for which the functional protective antigen has been identified, (4) that involve foreign animal/zoonotic organisms that are dangerous to humans, and (5) that involve pathogens that can be easily spread to wildlife populations. Vaccines identified as the highest priorities were those for rabies, Leptospira spp., Clostridium spp., Erysipelas, foreign animal diseases (FAD), poultry diseases, and fish diseases. Further research on the identification, purification, and characterization of vaccine protective antigens in veterinary vaccines was also identified as a priority. Workshop participants recommended priority research, development, and validation activities to address critical knowledge and data gaps, including opportunities to apply new science and technology. Recommendations included (1) investigations into the relative impact of various adjuvants on antigen quantification assays, (2) investigations into extraction methods that could be used for vaccines containing adjuvants that can interfere with antigen assays, and (3) review of the current status of rabies and tetanus human vaccine in vitro potency methods for their potential application to the corresponding veterinary vaccines. Workshop participants recommended enhanced international harmonization and cooperation and closer collaborations between human and veterinary researchers to expedite progress. Implementation of the workshop recommendations is expected to advance alternative in vitro methods for veterinary vaccine potency testing that will benefit animal welfare and replace animal use while ensuring continued protection of human and animal health.

Abstract
NICEATM and ICCVAM convened an international workshop to review the state of the science of human and veterinary vaccine potency and safety testing methods, and to identify opportunities to advance new and improved methods that can further reduce, refine, and replace animal use. This report addresses methods and strategies identified by workshop participants for replacement of animals used for potency testing of human vaccines. Vaccines considered to have the highest priority for future efforts were (1) vaccines for which antigen quantification methods are already developed but not validated, (2) vaccines/components that require the largest number of animals, (3) vaccines that require an in vivo challenge test, and (4) vaccines with in vivo tests that are highly variable and cause a significant number of invalid tests. Vaccine potency tests identified as the highest priorities for replacement were those for diphtheria and tetanus, pertussis (whole cell and acellular), rabies, anthrax, polio vaccine (inactivated) and complex combination vaccines based on DT or DTwP/aP. Research into understanding the precise mechanism of protection afforded by vaccines and the identification of clinically relevant immunological markers are needed to facilitate the successful implementation of in vitro testing alternatives. This report also identifies several priority human vaccines and associated research objectives that are necessary to successfully implement in vitro vaccine potency testing alternatives.
