An inhalable COVID-19 vaccine developed by China's CanSino Biologics has shown an increase of 250- to 300-fold in neutralising antibody levels as a booster shot, the media reported. In contrast, taking an inactivated vaccine as a booster after two inactivated vaccine shots, increases the neutralising antibodies by only 30 times, it added.
