The World’s First Inhaled COVID-19 Vaccine Approved By China

On Sunday, China became the first nation to approve the world’s first inhaled COVID-19 vaccine. This needle-free version of the vaccine, called Convidecia Air for Coronavirus, will also have the adenovirus vector technology, which is similar to the injectable version of the vaccine.      

Since August, over 70 cities in China have been under full or partial lockdown due to the spreading of COVID-19. According to the CNN Italy reports, this has severely affected more than 300 million people.  

So, the inhaled vaccine version will be a great initiative to control and prevent coronavirus from spreading. This inhaled vaccine option will hopefully convince more people to get boosted because new versions of the coronavirus are still spreading.

The Convidecia Air vaccine has been on trial and tested on different groups of people. In July, Chinese scientists published a study that showed that around 92.5% of people had developed neutralizing antibodies after four weeks of taking this vaccine. 

This needle-free option currently gets emergency use approval as an inhaled booster in China. The Chinese company CanSino Biologics Inc states that “the country’s drug regulator had approved the inhaled version of a coronavirus vaccine for emergency use as a booster.”

What is Convidecia Air?

Convidecia Air vaccine, developed by the Tianjin-based company CanSino Biologics Inc is the inhaled or needle-free version of the COVID-19 vaccine. It has recently been approved by the National Medical Products Administration of China but only as a booster vaccine for emergency use. 

Compared to intramuscular vaccines, this intranasal vaccine doesn’t need low-temperature storage for mass vaccination. Even there is no requirement for health professionals to administer them. 

How Does the Inhaled Covid-19 Vaccine Work?

The Convidecia Air comes in liquid form in disposable devices, which will change into an aerosol using a nebulizer. These vaccines are self-administered and can easily be inhaled through the mouth with the help of a nebulizer machine. 

The company explained that this version of the COVID-19 vaccine could stimulate cellular immunity and induce mucosal immunity, which will boost immunity and protection even without getting an intramuscular injection.  

Just after announcing the vaccine’s approval on Sunday, the next day, the stock prices of CanSino jumped 8% in Hong Kong.

Is It Really Effective?

Now the main question that we all have in mind is whether this inhaled vaccine works and, if so, how effective it is.  

The inhaled version of CanSinoBIO’s vaccine was in trials last year in July, and the results show that it triggered immune responses without showing any serious side effects.

So, does this indicate that intranasal vaccines are better than intramuscular vaccines?

Mint has released a report that shows that two inhaled doses of the Convidecia Air vaccine, which were given to people in 28 days difference, produced similar levels of antibodies compared to the single dose of injection. 

According to World Health Organization (WHO) data, “CanSino’s new product is one of two specifically “inhaled” vaccines that had reached clinical phase development, as a number of companies worldwide research innovative ways to deliver Covid-19 protection via the nose and mouth.”

Final Thoughts

China may be the first to approve the inhaled COVID-19 Vaccine, but other countries, including the US, UK, and India, are also accelerating their efforts to develop nasal spray vaccines. 

This needle-free vaccine option sounds great; however, CanSinoBIO said it is still uncertain when the vaccine will finally be available. The sales will depend on the future COVID-19 situation and vaccination rate in China and in other countries.
