CDSCO flags Abhayrab rabies vaccine batch as substandard after potency failure
Published · Updated
What happened
The Central Drugs Standard Control Organisation reported that a batch of Abhayrab rabies vaccine failed potency testing and was classified as substandard and potentially spurious. The product is widely used in India for rabies prevention after animal bites, and the regulator's action follows an earlier episode involving suspected counterfeit Abhayrab doses.
Why it matters
Rabies prophylaxis depends on timely administration of effective vaccine doses, so a potency failure can disrupt treatment protocols, trigger batch tracing, and force procurement shifts at hospitals and state health systems. The case also raises immediate questions about manufacturing controls, distribution-chain integrity, and whether additional batches need testing or recall action.
India's drug regulator has flagged a batch of the widely used Abhayrab rabies vaccine as substandard and potentially spurious after it failed a potency test. The notice was issued on September 18, 2026, making this a live drug-quality and public-health event because rabies post-exposure vaccination is time-sensitive and supply substitutions may be needed quickly. The development also revives concerns around counterfeit or compromised rabies vaccine circulation after a previous Abhayrab-related episode within the past two years.
