The Tamil Nadu government on Friday urged the Centre to allocate an "assured supply" of 20 lakh doses of covid vaccines to ensure unhindered immunisation and batted against any restriction on supply of Remdesivir, used in Covid-19 treatment.

Chief Minister K Palaniswami told Prime Minister Narendra Modi that an Integrated Vaccine complex near here was ready and appealed that it be brought to working condition at the earliest to augment production of COVID vaccines.

In a letter to Modi, the chief minister said directions are being issued by National and "certain State regulators," prioritising supplies by individual manufacturers to certain states and restricting Remdesivir sales only within the state where the drug was being produced.
