Now this vaccine has been popularized in COVID-19. How long will the human body produce antibodies after vaccination?

Novel coronavirus vaccine is a new type of vaccine, which is widely concerned by people, and is mainly used to prevent and treat COVID-19. There is a certain emphasis on the injection of new coronary artery disease vaccine, so how long does it take for the new coronary artery vaccine to produce antibodies after one injection?

How long does it take to produce antibodies after vaccination According to the preliminary clinical trial results of inactivated vaccine in COVID-19, about two weeks after vaccination, the immune effect of vaccinated people is better.

Through the analysis of the published COVID-19 vaccine literature, it was found that the inactivated vaccine in COVID-19 still had a good immune effect two weeks after inoculation. Clinical trials show that antibodies are generally produced within 7 days after the new coronary angiography vaccine is inoculated, and the antibody positive rate is about 60%-90% within 14-28 days, and the antibody positive rate exceeds 90% after one inoculation, forming a continuous protection mechanism.

After immunization, people will produce a protective antibody, and some vaccines can also make people have cellular immunity, thus forming corresponding immune memory. In this way, the human body has disease resistance and immunity. Once novel coronavirus invades the human body, antibodies produced by vaccines and cytokines released by cellular immunity can recognize, neutralize or kill the virus, and immune memory can quickly activate the immune system, so that the virus cannot continue to proliferate in the body, thus achieving the purpose of preventing diseases.

Is the new coronary artery vaccine lifelong immunity? No vaccine can provide the protection rate of 100%, and a few people may still have no protection or get sick after vaccination. The protective effect of COVID-19 vaccine has reached a very high level. The current data show that the antibody has existed in the body for at least half a year, and there is not enough evidence to prove that it can be immunized for life. Therefore, it is suggested that even if vaccinated, the personal protection level cannot be lowered.

Who can't get novel coronavirus vaccine 1? People who are allergic to any ingredients contained in this vaccine include auxiliary materials and substances used in the preparation process.

2. People suffering from acute diseases, severe chronic diseases, acute chronic diseases and fever.

3. Patients with a history of convulsion, epilepsy, Guillain-Barre syndrome, other progressive neurological disorders, encephalopathy or mental illness.

4. Have had severe allergic reactions (such as acute allergic reactions, urticaria, skin eczema, dyspnea, angioneurotic edema or abdominal pain) after vaccination in the past, or have had severe allergic reactions and any nervous system reactions after vaccination in the past.

5. Pregnant and lactating women,1unvaccinated people between 8 and 59 years old.

What should I pay attention to after vaccination in COVID-19? 1. After vaccination, you should stay in the vaccination unit for 30 minutes. During the observation period, if you have symptoms such as pale face, sweating, cold limbs, rash, weak pulse, cyanosis, swelling of face and throat, and difficulty breathing, please go to the inoculation site immediately.

Second, after inoculation, rest more, drink more water, keep the injection site clean and sanitary, and do not clean or massage the inoculation site to prevent local infection.

Three, after vaccination should check the vaccination appointment, grasp the next vaccination time.

Four, after vaccination, fever, local redness and pain and other reactions, in addition to symptomatic treatment, should immediately notify the doctor of the vaccination unit to make relevant records; If you have a high fever or persist for several days or other more serious conditions, you should go to the hospital in time to avoid delaying your illness.

Five, vaccination is the main measure to prevent pneumonia in COVID-19. After immunization, we should still adhere to the prevention and control measures such as wearing a mask, washing hands frequently and taking temperature.

COVID-19 vaccine, a new coronary artery vaccine with side effects and sequelae, has entered three clinical trial stages. A universal vaccine is widely used, which is basically safe and reliable without great side effects. A few people may have some allergic reactions or other discomfort, but there are no serious side effects and sequelae. These side effects and sequelae may lead to the following consequences:

First, after vaccination with novel coronavirus vaccine, few people will have symptoms such as headache, dizziness and fever. Some people will have lumps at the inoculation site after vaccination, and they will feel tingling when touching them with their hands. A few patients also have adverse reactions such as cough, vomiting, abdominal pain, diarrhea and loss of appetite.

Second, because of vaccination, including people infected with COVID-19. This population will have a coupling reaction after vaccination.

Therefore, the test results of the above side effects still have some deviation. Finally, through a return visit to the patients who have been vaccinated with novel coronavirus vaccine, most patients have no adverse symptoms after vaccination.
