India's drug regulator flagged a batch of the Abhayrab rabies vaccine as substandard and potentially spurious after laboratory tests revealed potency failures. The discovery marks the second time in less than two years that counterfeit doses of the frontline treatment have surfaced. The incident affects a nation that records nearly 6,000 rabies deaths annually.
