has three natural enemies in human history: war, famine, and plague. However, at the end of 2019, the sudden outbreak of the new crown epidemic broke out, which is the widest coverage and the most serious impact of social incident .
"Youth is only a few years, and the epidemic takes up three years." This sentence is widely circulated on the Internet, and netizens expressed their feelings in the face of the long-lasting COVID-19 epidemic.
At the end of 2020, many places across the country had already started vaccination with the new crown vaccine . Until 2021, the vast majority of people had completed the third dose of the new crown vaccine. After receiving the COVID-19 vaccine, some people are still infected with the COVID-19 virus, which makes people wonder, is the COVID-19 vaccine of no effect?
Why are you still infected with the virus after receiving the new crown vaccine?
Although my country's epidemic prevention and control policies are relatively complete, there are still repeated outbreaks in many places across the country, and many people who have been vaccinated with new vaccines will be infected with the new coronavirus. Is this the new coronavirus vaccine not effective?
I wonder if you have discovered that after receiving the COVID-19 vaccine, most of the infected people who came out are asymptomatic or mild infections, and there are almost very few severe infections. This proves that the COVID-19 vaccine has a positive role in preventing and treating severe cases and reducing the mortality rate of COVID-19 .
Regarding the reasons why the virus will be infected after vaccination, the experts explained this:
0 1 You will still be infected after getting the new crown vaccine because the vaccine cannot achieve 100% protection. It can only improve the body's immunity, reduce the chance of infection, and no particularly serious lesions will occur after infection.
No vaccine can achieve 100% protection. Some vaccines will definitely produce certain antibodies after injection. When a virus enters the human body, the antibodies will exert a certain resistance to the virus, so they can inhibit the growth and reproduction of the virus. The number of viruses that grow and reproduce is relatively small, which is not enough to cause severe illness. However, because viruses enter the body, a small amount of reproduction will occur, so there will be certain infections.
Some people may produce relatively small amounts of antibodies in their bodies due to personal physical reasons after being vaccinated, so there is also the possibility of infection. Because everyone has different physiques after all, the reactions they produce after vaccination are also different. However, clinical trials have shown that the protection rate can be effectively enhanced after vaccination.
Facts have proved that vaccination with the new crown vaccine is the most effective means to reduce infection, severe illness and death. At present, whether it is children over 3 years old, young people, or the elderly, vaccination with the new crown vaccine is an option to prevent and control the new crown epidemic.
New crown vaccine has added new ways to strengthen immunization? What is an inhaled COVID-19 vaccine?
On September 4, 2022, the newly developed recombinant novel coronavirus vaccine for inhalation (type 5 adenovirus vector), was proposed by the National Health Commission, and the National Medical Products Administration organized a demonstration and agreed to be included in emergency use as a strengthening injection, becoming the world's first inhaled new coronavirus vaccine.
The new crown vaccine is further developed through respiratory mucosal immunization technology. The vaccine is atomized into tiny particles by aerosolized inhalation, and enters the respiratory tract and lungs through oral inhalation, which can stimulate the mucosal immune response. This immune method cannot be brought about by intramuscular injection and provides additional protection in respiratory mucosal tissue.
New Coronavirus Pneumonia As a respiratory disease, the human body's immune response to the new coronavirus first occurs in the respiratory mucosa and oral mucosa. Although traditional intramuscular vaccination can produce systemic immunity throughout the body, studies have shown that its mucosal immune response is weak, and the basic immunity needs to be effective to complete the full vaccination process for 7 to 14 days.
At present, the clinical research results of inhaled recombinant coronavirus vaccine sequentially strengthening immunity with inactivated novel coronavirus vaccine conducted by inhaled recombinant coronavirus vaccine in healthy adults aged 18 and above in my country show that the sequential strengthening of immunity with inhaled recombinant coronavirus dosage form and inactivated vaccine sequentially strengthening immunity can significantly enhance the immune response.
immuno persistence study showed that the antibody level of the inhaled vaccine group against Omickron was 6 times that of the recombinant protein vaccine group and 14 times that of the inactivated vaccine group. Research on the persistence of inhaled vaccine immunity shows that after 6 months of vaccination at the Institute of Epidemic, the level of neutralizing antibodies that were much higher than that of the inactivated vaccine homologously strengthened against the original strain and the Omickron variant strain.
Who is not suitable for inhalation recombinant coronavirus vaccine?
No matter what disease it is, as long as the patient has clinical manifestations of high fever, such as fever caused by a cold or urinary tract infection, he or she cannot receive the inhaled COVID-19 vaccine. He or she must wait until the disease is cured before considering vaccination.
. Acute patient population
When the patient suffers from certain acute diseases, such as severe colds and bedridden or fractures in certain parts of the body.
. People with impaired immune function
This group of people mainly refers to people whose patients are undergoing chemotherapy due to a certain disease, or who suffers from certain serious diseases, resulting in a decrease in their autoimmunity.
are allergic to the active ingredients in this product, any inactive ingredient, substances used in the production process, or those who have experienced allergies when vaccinated with the same type of vaccine before. How to get inhaled vaccine with
?
Recommended subjects to practice a few times before inhaling before formally starting vaccination.
. Hold the atomized cup in the mouth and inhale deeply until there is no fog in the cup;
. Hold the breath for more than 5 seconds (at least 5 seconds), then breathe normally, and the inoculation is over.
Things to note after inhaled COVID-19 vaccine
. Avoid excessive stimulation after vaccination and keep the nasal cavity clean.
. Pay attention to the intensity of exercise after inhaling the vaccine. You can exercise, but it needs to be appropriate.
