Abhayrab Potency Test Raises Questions Over Seized Vaccine Vials
A rabies vaccine sample that was seized reportedly did not pass a strength test.
The company that makes Abhayrab says the seized vials were not made by it.
This means investigators still need to determine whether the sample was genuine.
The findings do not prove that every Abhayrab vaccine is unsafe.
They also do not prove that the real KE25012 batch failed its quality tests.
People who received a rabies vaccine after an animal bite should not stop their treatment on their own.
Anyone worried about a vial or batch number should contact a doctor or health authority.
Getting advice quickly is important after possible rabies exposure.
