Amid a sharp uptick in Covid-19 cases globally, especially in neighbouring China, the government on Friday approved Bharat Biotech's intranasal vaccine as a booster dose for those aged 18 years and above. 

The vaccine, named iNCOVACC, had received approval of the drugs regulator in November for restricted use in an emergency situation as a heterologous booster dose. Heterologous booster means a person can be administered a different vaccine as a third shot from the one that he/she received as the primary dose.

As India steps up surveillance to thwart a possible Covid wave, the Centre has appealed to eligible citizens to get their booster or precautionary third dose. The coverage of the precautionary dose has been inadequate.

So far, about 22.35 crore booster doses have been administered, which is just 27 per cent of the total population eligible for boosters.
