There is no need to “inject”, just “inhale”, an inhaled new crown vaccine is already applying for emergency use.On June 3, at the Pujiang Innovation Forum plenary meeting, Chen Wei, a researcher at the Academy of Military Sciences, vice chairman of the Chinese Association for Science and Technology, and academician of the Chinese Academy of Engineering, said that he was applying for emergency use of aerosolized inhaled new crown vaccine.
According to reports, compared to the humoral and cellular immunity formed by the injectable new crown vaccine, the inhaled new crown vaccine can also form mucosal immunity. This triple immunity is the most ideal state.
The so-called nebulized inhalation immunity is the use of a nebulizer to atomize the vaccine into tiny particles, which enter the respiratory tract and lungs through breathing inhalation, thereby stimulating mucosal immunity, which cannot be brought by intramuscular injection.
Normally, the new crown vaccine injected intramuscularly can only induce humoral immunity and cellular immunity. In addition, the use of aerosol inhalation method for immunization is painless and has higher accessibility.
Academician Chen Wei said that all vaccines are now injected, but in fact, they can be inoculated by other methods, such as aerosol inhalation. We first published the results of non-injectable vaccines in August last year. The clinical trial was carried out in Wuhan on September 29 last year, which was fascinating.
She explained that the nebulized inhalation vaccine only needs one-fifth of the dose of the injection vaccine, and the bottleneck problem of the vaccine bottle can be solved without the need to bottle one.
“If the vaccine is inhaled by atomization, it will still have mucosal immunity.” Chen Wei said, “The Food and Drug Administration has approved the approval for the expansion of clinical trials, and we are now applying for emergency use.”
