Beijing provides inhalable COVID vaccines as booster

China's capital Beijing is providing inhalable COVID-19 vaccines as a booster dose in a bid to further encourage the population to get vaccinated amid another surge in coronavirus outbreaks across the country.

As of mid-October, 90% of Chinese were fully vaccinated and 57% had received a booster shot. At least 11 districts in Beijing have begun taking appointments for taking the inhalable vaccine as a booster dose starting this week, according to the Global Times.

The inhalable vaccine was developed by Chinese biopharmaceutical company CanSino Biologics Inc. as an aerosol version of the company's one-shot adenovirus vaccine, which uses a relatively harmless cold virus. About a dozen nasal vaccines are being tested globally, according to the World Health Organization.
