Could CanSino’s inhaled coronavirus vaccine booster be a quick, needle-free option?

CanSino’s inhaled Covid-19 vaccine booster induces a higher level of immune response for those vaccinated with two Sinovac shots than a third dose of the Sinovac vaccine, a team of Chinese researchers has found.

Study participants who received the CanSino booster showed “much stronger neutralising antibody responses” – at nearly seven to 11 times higher than that of a three-dose regimen of the Sinovac shot – according to the study of 420 people. The study has not been peer-reviewed.
