China’s most populous city, Shanghai, has started rolling out the world’s first inhalable COVID-19 vaccine on Wednesday Oct. 26.
Chinese pharmaceutical company CanSino Biologics created the vaccine, which authorities approved as a booster in September.
Videos on Chinese social media show users inhaling the vaccine through a white, almost bubble tea-like, cup for at least 20 seconds.
“It was like drinking a cup of milk tea,” one Shanghai resident said.
Scientists say inhaling the vaccine could increase immunity in the regions where COVID-19 first enters the body.
Medical health personnel hope the inhalable COVID-19 vaccine can help lower vaccine hesitancy.
“There is a large proportion of people who are resistant to take the vaccine because they have a needle phobia. They may not articulate it, but that’s what in their mind,” a medical health officer told Reuters.
Millions of people have gone undergone lockdown once again in China as the government enforces its strict zero-COVID policy, an ambition plan to eradicate COVID-19.
