So far indigenously developed Zydus Cadila’s needle-free COVID-19 vaccine ZyCoV-D has received emergency use authorisation from the drug regulator, making it the first vaccine to be administered in the age group of 12-18 years in the country.

“With cases rising in Kerala, adequate steps should be taken to contain the inter-state spread of COVID-19,” Health Minister Mansukh Mandaviya said in a statement after speaking with his state counterparts in Tamil Nadu and Karnataka, which border Kerala.

He asked them to increase vaccination in the districts close to Kerala. India has so far administered 662 million doses, with at least one dose in 54% of its 944 million adults and the required two doses in 16%.
