Early study results show CanSino’s inhaled vaccine for COVID-19 triggered an immune response similar to its injected counterpart.

Both Nasdaq- and Hong Kong-listed shares in Chinese health-related companies have been free falling with heavy volumes, after foreign investors spooked by China's general crackdown on the tech sector rushed to exit.

However, insurers are unlikely to offer lower premiums to those vaccinated, even as the prospects for an overall hike remain uncertain, say experts.
