The world's first inhaled COVID-19 vaccine developed by Chen Wei's team was unveiled. How to spray inhalation?

Academician Chen Wei's team developed the world's first inhaled COVID-19 vaccine, which was exhibited at the 200215th Hainan International Health Industry Expo. Pneumonia vaccine for inhalation and COVID-19 vaccine for intramuscular injection have not changed, but the administration methods are different.

What about atomizing inhalation?

First of all, the method of atomized inhalation is also very popular now, such as atomized inhalation, which is now used to treat cough and local bronchitis, and is also very popular in clinic. Atomization inhalation has the advantages of quick action, little side effect and little harm to human body, and the effect is relatively direct, and the process of atomization inhalation can be completed in a short time. Atomization inhalation is to atomize the vaccine into fine particles with an atomizer, and then enter the human respiratory tract and lungs through oral inhalation. This effect will be more obvious, because it can directly reach the respiratory tract, which can better stimulate human mucosal immunity.

It is understood that the human mucosal immunity brought by this way of atomizing inhalation is intramuscular injection. With the continuous progress of scientific research, clinical achievements are getting bigger and bigger. The method of atomizing inhalation will be safer and there will be no adverse reaction of intramuscular injection. For example, after intramuscular injection, some people will have local swelling and pain, induration, itching and redness. It will be good for people if this method of atomizing inhalation is used during the third injection. Atomization inhalation requires special equipment to atomize the prepared vaccine into tiny particles, which can stimulate the triple protection of humoral immunity, mucosal immunity and cellular immunity through inhalation. COVID-19 vaccine of 1 and the second injection is injected into the anterior muscle, so if the third injection is inhaled by atomization, the immunity can be enhanced and a high level of comprehensive antibody can be produced. This method is more suitable for large-scale inoculation. Still use the original formula, but change the way of administration.

Advantages of atomizing inhalation of COVID-19 vaccine.

There will be no local adverse reactions caused by intramuscular injection, which is good news for people who are afraid of needles, especially when vaccinating young children, this cooperation will be greatly improved. This can also improve and popularize the willingness to vaccinate. This method also reduces the problem of medical waste treatment, because simple atomization inhalation replaces injection, so it reduces the problem of syringe treatment, and also reduces the risk of needle injury of medical staff, thus reducing the risk of occupational exposure. This method is simple and easy to operate, which can reduce the burden on medical staff, and the output of atomized inhalation vaccine will be greater than that of similar vaccines injected by muscle.
