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

2. Inoculation: You should bring your ID card, wear a mask, 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; Take more rest and drink more water after inoculation, and do not exercise excessively.

The practical significance of supplementary immunization with COVID-19 vaccine is the same as that of basic vaccination. Six months after vaccination in COVID-19, the level of comprehensive antibody in human body will be reduced to some extent. Therefore, if a booster immunization can be carried out half a year after the whole immunization, the antibody level will increase obviously in a short time.

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

COVID-19 vaccine booster needle is suitable for people who have successfully completed the whole course of 2 injections, have no skin allergy, and are more than 6 months away from the second vaccination.

According to the safety data of the phase I/II clinical study of COVID-19 vaccine booster, there was no significant difference in the total incidence of side effects between the second dose and the third dose after the third dose was given to people aged 18-59 and over 60. According to the experimental statistics of small-scale taxpayers aged 3- 17, there is no significant difference in the incidence of side effects between the three doses of COVID-19 vaccine and the two doses.

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