"No need to get an injection, the 'inhalation' new crown vaccine is very convenient, easy to operate and easier to accept." At 9 o'clock this morning, the new crown vaccination clinic of Tianshan Traditional Chinese Medicine Hospital in Changning District welcomed the first batch of citizens who were vaccinated with the "inhalation" new crown vaccine. The entire vaccination process is less than one minute, and citizens generally have high acceptance.
Starting yesterday (25th), Shanghai launched the inhaled recombinant coronavirus vaccine (type 5 adenovirus vector) to strengthen immunization appointment registration. Start strengthening immunity from today (26th). According to relevant national requirements, citizens currently only need to receive one dose of homologous enhancement immunization or sequential enhancement immunization. Citizens who have not yet undergone enhanced immunization are requested to complete the vaccination as soon as possible.
"Just like inhaling air, I hope the vaccine will add another barrier"
"After learning the news, I made an appointment to register as soon as possible." Mr. Zhu, a citizen, had received two doses of inactivated COVID-19 vaccine. After completing personal information registration and signing the "New Coronavirus Vaccine Informed Consent Form", he came to the vaccine "inhalation vaccination" area.
Before the vaccination begins, the nurse asked Mr. Zhu to take a deep breath and then hand him a foggy cup. Mr. Zhu took a deep breath with his mouth and sucked the mist in the cup into his body until there was no fog in the cup. After that, Mr. Zhu held his breath for another 5 seconds before the entire vaccination was completed.
When the reporter asked about his feelings about this vaccination, Mr. Zhu said, "I don't feel much, just like inhaling air. I hope this vaccine can add another barrier to myself."
It is reported that the recombinant new coronavirus vaccine for inhalation (type 5 adenovirus vector) mainly includes atomization and inhalation. The vaccine solution is atomized into fine particles through atomization equipment and injected into the atomization cup. The recipient then needs to complete the deep-absorbing oral inhalation process within 15 seconds and hold his breath for at least 5 seconds.
He Jinhui, head nurse of the Infectious Disease Department of Tianshan Traditional Chinese Medicine Hospital, introduced that if citizens have obvious mist gas in the atomized cup after inhalation; or if coughing or exhaling in advance during inhalation, during the 5-second period of breath holding, one dose of the vaccine needs to be inhaled again, and repeated inhalation is only allowed once. After the
vaccination is completed, Mr. Zhu must stay on site for 30 minutes before leaving. The nurse reminds that you should avoid contact with known allergies and common allergens in the past within one week after vaccination. It is recommended to drink more water, rest early, avoid strenuous exercise, try not to drink alcohol, and do not eat spicy, irritating or seafood foods.
This afternoon, Huangpu District Integrated Traditional Chinese and Western Medicine Hospital specially added a "inhalation" new crown vaccination service. Song Haiping, deputy director of the hospital, told reporters, "There are many citizens who have been consulted by phone, and everyone's willingness to get vaccinated is very high."
It is reported that the routine vaccination time of Huangpu District Integrated Traditional Chinese and Western Medicine Hospital is from 2:00 to 4:00 on Tuesday, Thursday and Saturday. 20 people are booked every day, and all of them have been completed by this Saturday.
Gao Qiang, deputy director of Huangpu District Center for Disease Control and Prevention, introduced that the supply of recombinant new coronavirus vaccine (type 5 adenovirus vector) for inhalation in this district can meet the needs of citizens, and all vaccinated nurses have undergone online and offline training.
has completed enhanced immunization, and no further strengthening of immunization is carried out at this stage.
Domestic and foreign studies have proved that strengthening immunization of new coronavirus vaccine can enhance the protective efficacy and extend the protection cycle. Up to now, more than 23 million citizens in the city have completed the full vaccination of the new crown vaccine, of which more than 12 million citizens have completed enhanced immunization.
During the interview with the vaccination clinic, the reporter noticed that several citizens came to consult the "inhalation" new crown vaccine, but were persuaded by the nurses on the scene because they had completed enhanced immunization.
Gao Qiang emphasized in an interview with reporters that inhalation recombinant coronavirus vaccine (type 5 adenovirus vector) is not the so-called "fourth shot". According to relevant national requirements, citizens currently only need to receive one dose of homologous enhancement or sequential enhancement of immunity. This means that the subjects who have completed enhanced immunization will not be further strengthened at this stage.
" Compared with intramuscular vaccines, inhaled vaccines can avoid injections, non-invasive, painless, and foreign body sensation. They can also stimulate stronger cellular immunity and humoral immunity , and even produce mucosal immune response."Yang Zhendong, deputy director of the product group of the Strategic Marketing Department of CanSino Biologics, introduced. The clinical results of
show that the use of inhaled recombinant new coronavirus vaccine and inactivated vaccine to sequentially enhance immunity can significantly enhance the immune response. Immune persistence studies show that after 6 months of heterologous vaccination with recombinant new coronavirus vaccine, high levels of neutralizing antibodies remain. In addition, one-fifth of the intramuscular dose has caused a significant decrease in adverse reactions after vaccination (the intramuscular dose is 0.5 ml, and the inhaled dose is 0.1 ml).
At present, two doses of inactivated new coronavirus vaccine (including Beisheng , Wusheng, and Sinovac inactivated vaccine) and 18 years old and above who have completed 6 months of intramuscular recombinant new coronavirus vaccines, can choose to use inhalation Use recombinant new coronavirus vaccine (type 5 adenovirus vector) to strengthen one dose.
Shanghai citizens are free of charge at this stage. Foreigners in Shanghai, Hong Kong, Macao and Taiwan compatriots in Hong Kong, Macao and Taiwan are inhaled to strengthen immunization and still implement the relevant policies and requirements for strengthening immunization.
Experts remind that citizens who have not yet strengthened immunization are required to complete the vaccination as soon as possible. Citizens who meet the conditions can register online for strengthening immunization through the "Health Cloud" APP, etc., and go to the appointment clinic for strengthening immunization at the agreed time with their valid ID card to strengthen immunization. When vaccinating people aged 70 and above, they must be accompanied by their family members or volunteers.
