Chennai, Apr 26 (UNI) The Tamil Nadu government today denied AIADMK leader J Jayalalithaa's charge that four children, who died in Tiruvallur district, after they were administered measles vaccine on April 23, were given vaccines, beyond the expiry dates.
A release from the state Health department here said the vaccines, supplied by the Hyderabad based Human Biological Institute, had a manufacturing date of February this year and the expiry date is January 2010.
On Ms Jayalalithaa's charge that the government's decision to purchase cheap vaccines from a Hyderabad-based firm, instead of from the Pune-based firm, had resulted in the death, the release said the state government never directly procured the vaccines and they were supplied by the centre.
The vaccines were procured by the centre and distributed to the state governments, the release clarified.
Stating that there was no question of fault in the cold chain system in the Primary Health Centres (PHCs), where the vaccines were stored, the government said uniterrupted power supply is ensured to the cold chain system in the PHCs to ensure that the vaccines were stored in particular temperature.
Staff have been appointed to check the temperature round-the-clock and the temperature, recorded, twice in a day, mornings and evenings, is registered in a record. Besides this, the temperature was checked through a monitor fixed in the vials. When the colour changes in a particular vial, they were not used, it said.
Tamil Nadu topped in the country for its best maintenance of vaccines and drugs, it said.
Even the expert team from the centre, which had visited the PHCs to enquire into the death of four children, commended the cold chain system, the release added.
