Two Delhi residents were taken ill after being administered an anti-rabies vaccine dose at the NDMC Charak Palika Hospital in Moti Bagh.
Chandra Negi (45), the mother of a Delhi Police head constable, and NDMC employee Sunil (50) are now battling for life in the ICU of Safdarjung Hospital. Both victims were bitten by stray cats.
A case under Section 337 (causing hurt by an act endangering life or personal safety of others) has been registered at the South Campus police station against unknown persons.
Head constable Hari Singh Negi said his mother had gone to the hospital alone on Monday to get the third dosage of the anti-rabies vaccine.
"Her health deteriorated immediately. Another patient also fell ill after the vaccine," said Negi.
Negi said, "The NDMC hospital authority rushed them to Safdarjung Hospital when their condition went out of control."
"My mother suffered a brain haemorrhage and is in coma since the incident," he added.
Amit Prasad, NDMC director, public relations, said, "It was a new lot of vials that was administered to the two patients who fell ill. All vials have been sealed and no further vaccination is being given. We have ordered a probe into the matter. Our doctors are monitoring the patients in co-ordination with the doctors at Safdarjung."
Meanwhile, the police investigating officer said the anti-rabies vaccine in question was supplied to New Delhi Municipal Council (NDMC) by a renowned 40-year-old vaccine manufacturing company in Hyderabad.
"We are looking into the matter and action will be taken accordingly," the officer said.
