Hefei, the capital city of east China’s Anhui Province, recently started administering an inhalable COVID-19 vaccine.

The vaccine comes in a mist form that is sucked in through the mouth, and is being offered for free as a booster dose for previously vaccinated individuals.

The amount needed for the orally administered vaccine is just one-fifth of that given via needle. In addition, the droplets can fend off the virus as it reaches the mucosal surfaces and the rest of the respiratory system.
