Digital Desk: On October 26, Shanghai starts supplying an inhalable COVID-19 vaccination, which seems to be a first in the world. According to a post on an official city social media account, a free booster dose of the vaccine, which is a mist that is breathed in through the lips, is being made accessible to those who have already been inoculated.

Before loosening tight pandemic restrictions that are slowing the economy and pulling China further away from the rest of the world, China wants more people to get vaccinated. By mid-October, 90% of Chinese people had completed their vaccinations, with 57% receiving a booster dose.

Such "needle-free" vaccines are expected to increase vaccination rates in countries with weak health systems because they are easier to administer. They may also persuade those who dislike being injected in the arm to get immunized.

A vaccine administered as a mist, according to Dr. Vineeta Bal, may stop the virus before it spreads to the rest of the respiratory system. However, the size of the droplets would play a role in this. The Indian immunologist believes that larger droplets would train defenses in the mouth and neck, while smaller ones would penetrate deeper into the body.
