In China, an inhalable COVID-19 vaccination is being administered.
Officials in Shanghai say that the vaccine, which is a mist that is sucked into the mouth through the nose, is being offered free of charge to people who have been previously vaccinated.
Scientists believe that “needle-free vaccines” will make it easier for people to get inoculated in countries with fragile healthcare systems. They may also convince people who are afraid of needles to get vaccinated.
Chinawants to give more people booster shots before considering easing strict pandemic restrictions, which some feel are limiting the economy and are causing problems for the rest of us.
President Xi Jinping established the country’s strict zero COVID policy. This was designed to stop every outbreak and move quickly to restrict travel and impose lockdowns if only a few cases are found.
Millions of Chinese are now restricted to their homes and subject to mass testing programs. They also have to endure public travel control via apps.
There are indications that the rest of Asia could follow the lead of Hong Kong and Macau’s gradual lifting of COVID limitations.
Mid-October saw 90% of Chinese have been fully vaccinated, and 57% had received booster shots.
How zero-COVID policy has transformed cities into digital fortresses
An online Chinese state media outlet posted a video showing people receiving the new inhalable vaccine at a community healthcare centre and then sticking the translucent white cup’s short nozzle into their mouths.
According to the accompanying text, after slow inhalation, people hold their breath for five second, and then complete the whole process in 20 seconds.
One Shanghai resident stated in the video that it was similar to drinking milk tea. It tasted sweet when I inhaled it in.
Non-needle vaccines have not been thoroughly tested for their effectiveness. The inhalable vaccine was approved by Chinese regulators in September. However, it was only used as a booster shot because studies revealed that it stimulated an immune response in people who had received two doses of another Chinese vaccine.
The vaccine could be administered as mist to prevent the virus from reaching the rest of your respiratory system. However, this would depend on the size and composition of the droplets. Dr Vineeta Bali, an Indian immunologist, stated that the effectiveness of the vaccine is dependent on how large the droplets are.

France’s researchers began working on a nasal spray vaccine last year. However, the trials have been disappointing.
Indian regulators have approved a nasal vaccination, but it is still being developed.
According to the World Health Organisation, around a dozen nasal vaccinations are currently being tested worldwide.
China relies on its own vaccines, mainly two inactivated vaccines. These vaccines have been effective in preventing deaths and serious diseases but not as well as the Moderna and Pfizer vaccines in stopping disease spread.
Chinese authorities do not require vaccination. However, in order to enter an office building or other public areas, one must pass a negative check. This is not proof that you have been vaccinated.
A zero COVID policy ensures that only a very small percentage of the population has been infected. This is in contrast to other areas.
