What is an inhaled coronavirus vaccine?
The "Shanghai Release" public account article pointed out that the recombinant new coronavirus vaccine for inhalation (adenovirus type 5 vector) uses a harmless adenovirus vector to deliver genetic material expressing S protein into the human body, and uses a nebulizer to atomize the vaccine into tiny particles, which reach the lung tissue through oral breathing through inhalation to stimulate the triple immunity
of mucosa, body fluids and cells.
of mucosa, body fluids and cells.
Who can get the inhaled COVID vaccine?
According to the "Beijing Shijingshan" public account, the following groups of people can choose this vaccine: (1) People aged 18 and above who have completed basic immunization for 6 months
.
(2) The basic immunization here refers to those who have been vaccinated with 2 doses of inactivated vaccines (Beijing Biotech, Sinovac Zhongwei, Wuhan Biologics) or 1 dose of CanSino Biological adenovirus vector new crown vaccine (intramuscular dosage form).
(3) The inhaled new crown vaccine is only used for booster immunization and cannot be used for primary immunization

How to get the inhaled coronavirus vaccine?
According to the "Shanghai Release" public account article, vaccinated people should practice several times before inhaling, and then start formal vaccination
.
Step 1: Take a deep breath first (do not exhale into the atomized cup); Step 2: Mouth with atomization cup suction nozzle, deep inhalation until the cup is fog-free; Step 3: Hold your breath for more than 5 seconds (minimum 5 seconds), then breathe normally and the vaccination is over

What is unique about the inhaled vaccine?
The article of "Beijing Shijingshan" public account pointed out that inhalation of the new crown vaccine through oral inhalation can make the atomized vaccine through the respiratory tract and finally reach the lungs, while producing humoral immunity and cellular immunity, stimulate respiratory mucosal immunity, and respiratory mucosal immunity may be a more effective way to
prevent infection and block transmission.
prevent infection and block transmission.
Liu Yan, director of the Institute of Immunization and Prevention of the Hangzhou Center for Disease Control and Prevention, said that in addition to being convenient, fast and painless, the inhaled new crown vaccine has a more important advantage, that is, mucosal immunity
.
"Simply put, the new crown vaccine is inhaled through the mouth, so that the atomized vaccine finally reaches the lungs through the respiratory tract, stimulating the body to form a layer of protective antibodies on the surface of the respiratory tract, which can combine with the new crown virus to form a complex, and the complex is excreted through the oscillation of the respiratory tract mucosa
.
That is, through mucosal immunity, the first line
of defense for the virus to enter the human body is established.
