Chinese vaccine company CanSino Biologics said Sunday that China has approved its new path-breaking COVID-19 vaccine that can be inhaled.

The Convidecia Air Recombinant vaccines that are to be used as booster doses have been greenlighted by the National Medical Products Administration, China’s drug regulator.

The needle-free vaccine can induce immune protection from the virus after just one whiff of the drug, the company said on Twitter.
