The vaccine, called Convidecia Air, changes the liquid form of the vaccine into an aerosol using a nebuilzer. The vaccine can then be inhaled through the mouth using the nebulizer machine. 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.
Fortune.com on September 5, 2022 – China’s government approved the world’s first inhaled vaccine against COVID-19, the vaccine’s maker Cansino Biologics announced on Sunday.
In July, Chinese scientists published a pre-print study showing that people who received one booster dose of Cansino’s inhaled vaccine after two doses of the inactivated jab from Chinese maker Sinovac developed more antibodies than people who received three Sinovac shots. Four weeks after receiving the inhaled booster, 92.5% of people had developed neutralizing antibodies for Omicron.
Those who got three doses on Sinovac’s jab did not demonstrate any neutralizing antibodies for Omicron, either four weeks or six months after getting a booster.
