"There is no casual link of Pentavalent vaccine with the death of the children," Additional Professor, Department of Pediatrics, AIIMS, and chairman of the team, Dr Prof N K Arora, told reporters here.
The team from the Union Health and Family Welfare ministry had arrived here on Saturday after news reports that the Pentavalent vaccine administered to children in G B Pant Hospital and SKIMS was fake and was the root cause of death of eight children.
Arora said the team went through all clinical and laboratory records of the patients in both the hospitals and conducted a thorough investigation into the matter.
"The expert team went on a field visit to five districts in Kashmir to assess the full health system and the overall process of immunization at place in the valley.

Since its introduction in the state in February 2012, around 2.5 lakh doses of the vaccine had been administered to children across the state, officials said.
