Authorities in Shanghai have started administering an inhalable vaccine against Covid-19, apparently a world first, the Associated Press reported on Wednesday. The vaccine is being offered for free as a booster dose for previously vaccinated people, according to an announcement on an official city social media account, the report said. The vaccine is a mist that is sucked in through the mouth, the AP reported. A video posted by an online Chinese state media outlet showed people at a community health centre sticking the short nozzle of a translucent white cup into their mouths, the report said. The accompanying text said that after slowly inhaling, people hold their breath for five seconds, with the entire procedure completed in 20 seconds. “It was like drinking a cup of milk tea,” one Shanghai resident said in the video, according to the AP report. “When I breathed it in, it tasted a bit sweet.” View More
