Beijing started inhalation vaccination of new crown vaccine, now many districts announced the appointment information, the public can go to the vaccination according to the different vaccination site requirements, bring ID card.

“You first take a deep breath, inhale deeply, hold it, and hold your breath. 1, 2, 3, 4, 5, exhale.” At less than 9 a.m. on the 17th, a queue of people waiting to be vaccinated lined up in an orderly manner at the registration area of the vaccination site in Shangdi Street, Haidian District. Mr. Shang, who lives nearby, completed his inhalation vaccination of the new crown vaccine under the guidance of the staff. “I was also due for my third vaccination, and I saw the news of the inhalation vaccination launch yesterday, so I came here today.” After receiving the vaccine, Mr. Shang came to the detention area to wait, “Nothing special, I heard it was a little sweet, and I thought the sweetness was rather mild. The winter clothing is heavy, hard to put on and take off, inhalation vaccine is quite convenient.”

According to the introduction, the inhalation vaccine is suitable for people aged 18 and above who have completed the basic immunization for 6 months. Currently, the inhalation vaccine is only used for booster immunization and cannot be used for basic immunization. The results of related studies show that sequential booster immunization with inhalation recombinant neocoronavirus formulations and inactivated vaccines can significantly enhance the immune response.

Li Dong, chief physician of the Infection General Department at Beijing Youan Hospital, has described that the major difference between the inhaled vaccine and the injected vaccine is that it is inhaled through the mouth, which allows the nebulized vaccine to pass through the respiratory tract and eventually reach the lungs. While generating humoral and cellular immunity, it can act directly on the respiratory mucosa and produce protective antibodies in the respiratory mucosa. “We all know that the Omicron variant strain causes mainly upper respiratory tract symptoms. Therefore, inhaled vaccines have an advantage in preventing infections.”

“The composition of the inhaled adenovirus vector vaccine is identical to the composition of the intramuscular vaccine produced by the same company. The injectable vaccine dose is 0.5 ml per dose, while the inhaled vaccine dose is 0.1 ml per dose.” Shi Rujing, head of the planned immunization section at the Haidian District CDC, said that because the immune function of the elderly is relatively weak, the level of antibodies and the protective effect produced by people over 60 years old after completing the basic immunization with the new crown vaccine are relatively lower than those between 18 and 59 years old, so it is recommended that the elderly who are eligible for booster immunization should hurry to receive it. The inhaled Neocrown vaccine is one of the vaccines currently available for booster immunization of the elderly.

Vaccination is the most effective means of preventing and controlling infectious diseases, and “for people who do not have the means to receive intramuscular vaccination for various reasons, the inhaled vaccine certainly provides an additional option.” Li Dong has said that at present, the inhalation vaccine is only approved for use among adults aged 18 and above, and that future efforts to gradually relax the adapted population will be more affable for children who are afraid of injections.

At present, the city’s Dongcheng District, Xicheng District, Chaoyang District, Haidian District, Fengtai District and many other districts have announced the appointment and vaccination-related information. Shi Rujing said that the district has only opened one inhalation vaccination site in Shangdi Street, “the public response is enthusiastic, this vaccination site yesterday a total of 97 doses of new crown vaccine, of which 75 doses are inhalation vaccine. We may increase the number of vaccination sites depending on the situation.”
