China approved CanSino’s inhaled Covid vaccine

China has become the first one to approve an inhaled Covid vaccine.

The inhaled vaccine is made by a Chinese Pharmaceutical company CanSino. The vaccine has similar ingredients as its injected vaccine. But they use a harmless adenovirus as a carrier for the genetic code for the inhaled vaccine that guides the body on how to fight Covid. The company said that the vaccine Covidecia Air is inhaled as a fine mist and can provide good protection after just one breath.

Teams of researchers in the US and the UK have been investigating nasal spray vaccines. According to scientists, these vaccines may give added immunity to the upper airways and lining of the nose, from where Covid typically enters the body. CanSino is approved by the National Medical Products Administration of China for its inhaled vaccine to be used as a booster dose. The trial suggests that it can top up protection in those who previously had a jab.

Meanwhile, the latest Covid vaccine booster program has begun in Wales, Scotland, and England. Though infections are falling around the UK, health bosses predict a resurgence of flu and Covid this winter and autumn.
