Now the COVID-19 vaccine booster has been started. What are the precautions for COVID-19 vaccine booster? 1. If there are other vaccines, please remember that the interval should be at least 14 days.

2. Inoculation: You should carry your ID card and wear a mask during inoculation, do a good job of safety protection, and inform yourself of your physical condition and vaccination contraindications during inoculation.

3. After inoculation: After inoculation, you need to rest in the observation area for 30 minutes to observe whether there is any inoculation reaction, and report to the doctor immediately if there is obvious discomfort. Pay attention to the cleanliness of the inoculation site on the day of inoculation, and don't wet or dirty the injection site to prevent some infections; Rest and drink plenty of water after inoculation, and it is not advisable to exercise excessively.

The practical significance of COVID-19 vaccine booster is the same as that of basic vaccination. After 6 months of vaccination in COVID-19, the level of comprehensive antibody in human body will decrease. Therefore, if we can carry out a booster immunization in the second half of the whole immunization process, the antibody level will increase significantly in a short time.

At present, clinical research data show that even after 6 months of intensive injection, the antibody will decrease periodically, but it is still higher than the highest antibody value after 2 injections. Therefore, the practical significance of strengthening vaccination is that it can effectively improve the protective efficacy of COVID-19 vaccine and improve the resistance to mutant strains.

COVID-19 booster vaccine is suitable for people who have successfully completed the whole process of two doses of vaccination, have no skin allergy, and the interval between the second vaccination is more than 6 months.

According to the safety data of phase I/II clinical study of COVID-19 vaccine booster, there is no significant difference in the incidence of total side effects between the second dose and the third dose after the third dose of vaccine is administered to people aged 65-438 +08-59 and over 60. According to the statistics of small-scale taxpayer experiments on people aged 3- 17, there is no significant difference in the incidence of side effects between three doses of COVID-19 vaccine and two doses of vaccine.

The above is my detailed introduction. I hope it will be helpful to everyone after reading it. If you have any other comments, you can discuss them together in the message area below.
