Previously, the media reported that the future vaccine “inoculation” process may be more like drinking coffee. “One cup per person, take a cup of nebulized vaccine in front of the nebulizer that resembles a coffee machine, take a deep breath, hold for 5 seconds, breathe normally, and the vaccination is complete.

In order to ensure the safety and efficacy of this innovative vaccine are verified, this randomized, parallel controlled clinical study will recruit 420 subjects aged 18 and over who have completed 2 doses of inactivated vaccine and randomly assign them into three groups, each group will be randomized into three groups. 140 people were boosted with low-dose CanSino inhaled new crown vaccine (0.1ml), high-dose CanSino inhaled new crown vaccine (0.2ml), and intramuscular inactivated vaccine.

The results of the study show that the sequential strengthening of CanSino inhaled COVID-19 vaccine is safe, and the incidence of total adverse reactions is lower than that of inactivated vaccine homologous strengthening. Within 28 days after booster vaccination, no serious adverse reactions occurred in the inhalation group, and no clinically significant pulmonary function abnormalities occurred in the inhalation groups of different doses. The safety of the inhalation dosage form has been fully verified.
