Two hundred and forty pyridazinamine derivates were assayed for their ability to stabilize the Oral Polio Vaccine (OPV). Of these, pirodavir (R 77975) was selected for vaccine potency tests. Although pirodavir turned out to be an effective stabilizer of OPV, the protection induced by pirodavir was not better, nor additive to the effect by MgCl2 1 M, the usual stabilizer. Both stabilizers were effective in preventing damage to the viral proteins, but could not prevent damage of viral RNA.
