BEIJING (AP) — The Chinese city of Shanghai started administering an inhalable COVID-19 vaccine on Wednesday in what appears to be a world first.
The vaccine, a mist that is sucked in through the mouth, is being offered for free as a booster dose for previously vaccinated people, according to an announcement on an official city social media account.
Scientists hope that such “needle-free” vaccines will make vaccination more accessible in countries with fragile health systems because they are easier to administer. They also may persuade people who don’t like getting a shot in the arm to get inoculated.
