India's drug regulator on Tuesday allowed vaccine maker Serum Institute to enroll kids aged 7-11 years for its Covid-19 vaccine trial as the country prepares to protect children from the coronavirus, Reuters reports.

It has already administered more than 870 million doses to adults among its population of nearly 1.4 billion.

“After detailed deliberation, the committee recommended for allowing enrolment of subjects of 7 to 11 years of age group as per the protocol,” a subject expert panel of the Central Drugs Standard Control Organization said.

Serum Institute is already conducting a trial of its Covid-19 vaccine, a domestically produced version of AstraZeneca's shot, in the 12-17 age group and has presented safety data for an initial 100 participants.

So far, only drugmaker Zydus Cadila's DNA Covid-19 vaccine has received emergency use approval in India to be used in adults and children aged 12 years and above.
