TgPVR mice for neurovirulence testing of polio live vaccines (accredited by WHO)

The in vivo assay system developed by CIEA is used for the neurovirulence testing of polio live vaccines used around the world.
Previously, monkeys had been used in the safety testing of manufactured polio live vaccines, but sometimes wrong test results were obtained with monkeys because of the large inter-individual variability.
In addition, from the viewpoint of animal welfare and resources, monkeys can no longer be used.

Therefore, CIEA developed a highly precise neurovirulence test system for polio live vaccines using genetically modified TgPVR mice created by Dr. Akio Nomoto and his team.
As this test system has been demonstrated by polio research institutions and polio live vaccine manufacturers around the world to show higher precision as compared to the testing method using monkeys, it is now officially accredited by WHO and used for safety assessment as an alternative to monkeys.
The test system of TgPVR mice is the world's first test system established and accredited as a safety evaluation system for pharmaceuticals using genetically modified animals.
