Inhaled vaccine shows signs of promise

00:08①A two-dose inhaled COVID-19 vaccine developed by Chinese researchers appears to be safe and capable of eliciting strong immune responses comparable to those of its one-dose injected counterpart, a preliminary study released this week said.

00:25②Cansino Biologics, which created the vaccine with the Academy of Military Medical Sciences' Beijing Institute of Biotechnology, said it is the first company in the world to publish clinical data on an aerosol COVID-19 vaccine.

00:42③Results from its early stage human trial are promising and support further research into what promises to be an effective and economical candidate, it said.

00:53④The study's results were published in The Lancet Infectious Disease, based in the United Kingdom, on Monday. It recruited 130 volunteers aged 18 or older in late September. They were given five different vaccine combinations that varied in dosage and delivery method.

01:12⑤The results show that the inhaled vaccine, known as aerosolized Ad5-nCoV, was well tolerated, with no severe adverse reactions reported. The most common symptoms included fever, fatigue and headache.

01:28⑥In terms of efficacy, the study said one dose of the inhaled vaccine could induce a strong immune response, and after two doses, it "could produce similar SARS-CoV-2 neutralizing antibody titers(concentrations) as one dose of intramuscular vaccination".
