Anhui Zhifeilong Kema COVID-19 Third Needle How many times to inject COVID-19 Intensive Needle How often to vaccinate every needle

Now there are three types of virus extinguishing vaccine, one type of adenovirus vector vaccine and one type of cell recombinant vaccine on the market in China. Many people are in conflict about which one is better. In fact, as long as the vaccine is on the market, its safety must be guaranteed. Do not bother about which type of vaccine, and do you want a third shot of COVID-19 vaccine?

The recombinant COVID-19 virus vaccine (CHO cell) currently used is jointly developed by Anhui Zhifeilong Kema Company and the Institute of Microbiology, Chinese Academy of Sciences. CHO cell is the full name of Chinese hamster ovary cell, which is widely used in the field of bioengineering, and is the preferred cell for the production of protein drugs. In addition to the previous inactivated vaccine and adenovirus vector vaccine, the recombinant protein vaccine is the landing of the third COVID-19 vaccine technology route in China and the first recombinant protein vaccine approved for mass vaccination in the world, so it can be said to be of great significance. The principle of recombinant protein vaccine is that it only contains the virus antigen protein RBD (receptor binding region) protein, which is prepared by DNA recombination technology. After inoculation, it can stimulate the body to generate immunity against COVID-19, which is used to prevent diseases caused by COVID-19 infection.

For three doses of COVID-19 vaccine, the second dose should be administered 4 weeks after the first dose, and should be completed within 8 weeks after the first dose. The same is true for the third dose. The third dose should be administered 4 weeks after the second dose. It should be noted that the third dose should be administered within 6 months after the first dose, that is, the third dose of COVID-19 vaccine should be administered within half a year.

After vaccination, avoid scratching the vaccination site with your hands and be sure to observe for 30 minutes. Because after vaccination, a very small number of people may experience acute allergic reactions, which often occur within 30 minutes after vaccination. On site observation allows doctors to take timely treatment measures. It should be noted that the pressed cotton swabs after inoculation of COVID-19 vaccine cannot be taken away. They are stained with vaccine ingredients. If they are taken away at will, they may cause secondary pollution. They need to be discarded in the designated dustbin in the vaccination area.

If you get dizzy after taking COVID-19 vaccine, this situation does not need special treatment. It can generally relieve itself. This is the side effect of COVID-19 vaccine. It is recommended that you drink more water after taking COVID-19 vaccine, and eat more fresh fruits and vegetables to accelerate your metabolism and reduce the side effect of the vaccine.

According to some current clinical data, dizziness, fever, diarrhea and other side effects may occur after COVID-19 vaccination, but generally these symptoms will relieve or disappear within three days of vaccination, so the vaccinators need not be too nervous or worried. If you experience symptoms of dizziness, do not be overly nervous at this time. You should pay attention to rest, put down your work, keep your head warm, and avoid being stimulated by cold. It is also necessary to go to bed early and avoid staying up late, so that the body has enough sleep time. If the symptoms are severe, it is best to seek medical attention promptly and have a physician take targeted treatment measures.

At present, COVID-19 vaccine is gradually being popularized and popularized. Some adverse reactions may occur after vaccination. The severity of symptoms varies from person to person, but it is generally safe.
