Shanghai introduced a new type of COVID-19 vaccine that is inhaled rather than administered via injection.
 

Chinese regulators approved the vaccine, produced by Chinese pharmaceutical firm CanSino Biologics, for use as a booster in September.
 

And now the first people are starting to receive the vaccine, which is inhaled via the mouth from a vessel that looks like a take-out coffee cup with a short mouthpiece.
 

"Our body’s first line of defence is the mucus membrane of our respiratory system, we want that to be directly stimulated to improve immunity and using the inhaled vaccine does that," Dr Zhao Hui, chief medical officer at Shanghai United Family Hospital Pudong, told Reuters.
 

His hospital is among those administering the new vaccine, which will be used as well as regular injected shots.
 

Commenting on what he said was a first use of the technology, Erwin Loh, chief medical officer at St Vincents Health Australia, said the advent of inhaled vaccines was important not only because of their potential to guard against infection, but also because they could lessen vaccine hesitancy.
 

可以“吸”的新冠疫苗来啦

10月26日,全球首款吸入用重组新型冠状病毒疫苗(5型腺病毒载体)(简称“吸入式新冠疫苗”)在上海正式开始免费接种。
 

吸入式新冠疫苗接种过程主要包括雾化和吸入两部分,疫苗液被雾化为细小的颗粒注入雾化杯后,接种者须在15秒内完成口含深吸,并憋气至少5秒。整个过程不到一分钟。
 

接种了吸入式新冠疫苗的市民普遍反映,整个过程还是让人很容易接受的,吸入的感觉就像“喝饮料”,味道甚至还“有点甜”。
 

与肌肉注射的新冠疫苗相似,吸入式疫苗接种后,同样要在接种点留观30分钟。
 

据现场防疫人员对记者介绍,吸入式新冠疫苗利用对人体无害的腺病毒载体,将表达S蛋白的遗传物质递送进人体,利用雾化器将疫苗雾化成微小的颗粒,通过吸入的方式经口腔呼吸到达肺组织,激发黏膜、体液、细胞三重免疫。

吸入剂型目前推荐的接种人群是18岁及以上人群,如果有哮喘、慢阻肺、肺纤维化等呼吸道、肺部疾病的人群,暂不适宜这种接种方式。
