A New Antibody Binding Test for Potency Assessment of the Human Rabies Vaccine.

This study established a new protocol of the antibody binding test to evaluate the potency of the rabies vaccine containing the final bulk and the product. The principle of this experiment is to combine rabies vaccine with quantitative anti-rabies virus neutralizing antibody. After combination, the remaining rabies vaccine is combined with the quantitative fluorescent labeled rabies virus. After this, observe the remaining fluorescent labeled rabies virus, calculate the fluorescence area with fluorescence observation equipment, then calculate the potency of rabies vaccine by Reed and Muench method. The test results of many batches of rabies vaccine final bulk and finished products showed that the potency detected by this method was consistent with that of National Institute of Health method.
