Frontline workers and vulnerable adults will get booster jabs as the country battles a spike in cases.
India has begun giving booster doses of the Covid-19 vaccine to priority groups amid a surge in infections.
Early studies from other countries have suggested that a booster vaccine may provide more protection against Omicron.The highly transmissive Omicron variant was first discovered in South Africa in November. India has been mainly administering two locally-manufactured vaccines, Covishield and Covaxin, since its vaccination drive began in January 2021.
The government had begun administering vaccines to 15-18 year olds last week - it has said that 31% of Indians in this age group have been given the first dose so far.More than 91% adults have been partially vaccinated so far, while 66% have received both doses till now.
