The world's first inhaled COVID-19 vaccine has been approved in China.
 
The Chinese company CanSino Biologics Inc said on Sunday its inhaled version of a coronavirus vaccine had been approved by the country's drug regulator for emergency use as a booster.
 
The vaccine, called Convidecia Air, uses the same adenovirus vector technology as its sister injectable version. However, it provides a needle-free option that might convince more people to get boosted as new versions of coronavirus continue to spread.
 
The inhaled vaccine, which can be self-administered, changes the liquid form of the vaccine into an aerosol using a nebulizer so it can be inhaled through the mouth. 
 
The needle-free vaccine "can effectively induce comprehensive immune protection in response to SARS-CoV-2 after just one breath," CanSino said in a statement.
 
CanSino's initial jab has proved 66 per cent effective in preventing coronavirus infection, and 92 per cent effective against severe disease in early clinical trials, but outside China, it has struggled to compete with vaccines made by Sinovac and Sinopharm.
