CanSino said in a news release that a vaccine mist can give strong immune protection against COVID-19.
The first vaccine alternative to be used during the Pandemic was approved by regulators in China.
The jabs used in China contain the same ingredients as those used in the inhaled vaccine.
CanSino's vaccine has pieces of genetic material in it so the body can recognize it. The CanSino vaccine uses a harmless version of the common cold virus to carry information about the coronaviruses.
According to data from the World Health Organization, the single-dose CanSino shot is effective at preventing illness and preventing severe disease.
The mist was shown to be just as effective as the two-dose vaccine in clinical trials.
According to the press release, the mist may bolster protection in the lining of the nose and upper airway.
Every flu season, the FluMist vaccine is seen in the offices of doctors. Evidence from previous flu seasons shows that the mist doesn't always achieve the same level of efficacy as a shot.
If the mistable COVID vaccine provides enough booster protection to be approved and widely distributed in other countries, it will be known.
