Now, with the continuous improvement of the vaccination rate of the Covid-19 vaccine in China, the first batch of people to get the vaccine also began to get the "Booster vaccine". However, now academician Chen Wei's team has brought good news to the "needle fear" crowd.
Recently, at the 5th Hainan International Health Industry Expo, academician Chen Wei's team brought the world's first inhaled new crown vaccine, and this vaccine can also bring immune effects that cannot be achieved by intramuscular injection.
Mucosal immunity can be stimulated by intramuscular injection.
From November 12 to 14, the world's first inhalable new crown vaccine was unveiled at the "2021 5th Hainan International Health Industry Expo", and the audience can experience the use of inhalable new crown vaccine on site.
Inhaled neocrown vaccine and intramuscular injection used the same kind of vaccine, the formulation of the preparation did not change, and only different administration methods were used.Aerosol inhalation immunization refers to the use of atomizer to atomize the vaccine into small particles, which enter the respiratory tract and lungs through oral inhalation, so as to stimulate mucosal immunity, which can not be brought about by intramuscular injection.
Atomized inhalation vaccination was safe and had no local adverse reactions. Atomization inhalation only needs to use 1 / 5 dose of intramuscular injection, and the cellular immune response level can be equivalent to that of 1 dose of intramuscular injection.
Aerosol vaccination can induce strong humoral and cellular immunity, and has good tolerance, without causing any serious adverse reactions related to the vaccine. The adenovirus vector new crown vaccine approved by CFDA on February 25 this year for conditional listing. Under the condition that the formulation of the preparation has not changed, it uses special equipment to atomize the vaccine into small particles and enter the respiratory tract and lungs by inhalation, so as to stimulate the triple protection of mucous membrane immunity, humoral immunity and cellular immunity. Inhaled vaccine is suitable for use in a wide range of people.
