Luoyang starts inhalation vaccination for new crown

Read Time:5 Minute, 17 Second

“The whole vaccination process is like holding a milk tea cup and smelling it, then holding your breath to finish the vaccination, and there is no discomfort in your body.” On the morning of December 19, at the Jinguyuan Community Health Service Center in Xigong District, Ms. Lin, a 30-year-old citizen, met with a friend to receive the inhalation New Crown vaccine and became the first batch of people to receive the vaccination in Luoyang City.

What are the advantages of inhalation vaccination compared to traditional vaccination? Who can be vaccinated? What do you need to pay attention to? This reporter visited the vaccination clinic and asked the immunization planning experts from the CDC to answer your questions.

At present, what kind of inhalation vaccine can Luoyang citizens receive?

Tian Peng, an immunization planning expert from the CDC, introduced that at present, the inhaled vaccine that Luoyang citizens can receive is Kangxinuo inhaled recombinant new coronavirus vaccine (type 5 adenovirus vector), which passed the certification organized by the State Drug Administration in September this year and was included in the emergency vaccination queue of “sequential booster immunization”. Currently, the inhaled “recombinant” vaccine can be used as a “booster” and not as a first dose.

What is the protective effect of the inhaled Neocon vaccine?

Clinical studies have shown that booster immunization with inhaled Neocrown vaccine on top of 2 doses of inactivated vaccine resulted in 14 times more neutralizing antibodies against Omicron variant than homologous booster with inactivated vaccine and 6 times more than sequential booster with recombinant protein vaccine. Six months after the booster, neutralizing antibody levels well above those of the homologous booster were maintained.

How do I get the inhaled Neocrown vaccine?

The inhalation Neocrown vaccine is administered differently than the conventional Neocrown vaccine. The vaccination clinic provider needs to use a nebulizer to nebulize the vaccine into tiny particles and store the nebulized vaccine in a disposable nebulizer cup the size of a milk tea cup. The vaccine recipient needs to take a deep breath and then slowly inhale deeply into the nebulizer cup until there is no fog, and then hold his or her breath for 5 seconds to complete the vaccination. A simple summary of the process is “one exhale, two inhales, three breaths held”.

What are the reactions of the body after receiving the inhalation vaccine?

Ms. Lin, a citizen, said that she had a soreness in her arm after receiving the inactivated vaccine last year. But this time, when she received the inhalation New Crown vaccine, the whole vaccination process was like holding a cup of milk tea and smelling it, and then holding her breath to complete the vaccination, and there was no physical discomfort. “This vaccine smells salty.” Ms. Lin said with a smile.

In this regard, the medical staff of Jingu Park Community Health Service Center said in an interview that among the people who were vaccinated that day, some said that the vaccine smelled a little sweet, some said they smelled salty, and some did not smell the taste, which may vary from person to person.

What are the advantages of inhalation of the new crown vaccination?

Tian Peng, an immunization planning expert at the CDC, said that the advantages of this vaccination method compared to traditional vaccination are that it is non-invasive, painless, non-foreign body sensation, no adverse reactions such as arm soreness and swelling, and more convenient and comfortable.

Who can be vaccinated?

Currently, the inhalation “recombinant” vaccine can be used as a “booster” and not as a first dose. In other words, the public who need a booster shot has a new option.

Three conditions must be met for inhalation vaccination: (1) people aged 18 years or older; (2) people who have received two doses of inactivated neo-coronavirus vaccine or one dose of Convivox vaccine; and (3) people who have had an interval of 6 months or more from the previous dose.

Which groups are not suitable for vaccination?

(1) Those who are allergic to the active ingredient in the vaccine, any of the inactive ingredients, substances used in the manufacturing process, or those who have developed allergies during previous vaccinations of the same type.

(2) Those who have had serious allergic reactions to vaccines in the past (e.g., acute allergic reactions, angioneurotic edema, respiratory distress, etc.).

(3) Persons with uncontrolled epilepsy and other progressive neurological disorders, with a history of Guillain-Barre syndrome.

(4) Persons infected with neocoronavirus within 6 months

Can seniors choose to inhale the Neocon vaccine?

Yes! Seniors over 60 years old who have completed 2 doses of inactivated vaccine or 1 dose of adenovirus vector vaccine can receive the inhaled vaccine for booster after 3 months!

However, if you are a senior with a past history of asthma or poor lung function, or if you are over 75 years old, you should use the inhaled Neocon vaccine with caution and be advised to get the traditional Neocon vaccine instead.

What are the precautions?

(1) Withhold vaccination for acute illnesses and acute exacerbations of chronic diseases.

(2) Vaccination is temporarily suspended for serious chronic diseases in acute exacerbation, such as patients with tumors undergoing chemotherapy, patients with hypertensive crisis, patients with coronary heart disease with heart attack, patients with autoimmune neurological diseases in progressive stage, and patients with epilepsy in seizure stage.

(3) Use with caution in patients with a history of asthma, history of chronic obstructive pulmonary disease and underlying diseases such as pulmonary fibrosis or abnormal lung function.

(4) Use with caution in persons with a history or family history of convulsions, epilepsy, encephalopathy or psychiatric disorders.

(5) Observe at the site for at least 30 minutes after vaccination and communicate with medical staff if you are unwell.

Will inhalation of the vaccine affect the results of the nucleic acid test?

No! The inhalation vaccine does not contain neostriatal virus, so it will not cause false-positive nucleic acid tests in the surrounding environment during vaccine nebulization, nor will it affect the nucleic acid test results of vaccine recipients after vaccination.

Can all vaccination clinics administer the inhaled Neoconazole vaccine?

No. Currently, only some vaccination clinics in the city can administer the inhalation vaccine, so people can get the vaccination near them by following the information in the table below.
