Precautions for side effects of COVID-19 vaccine booster needle

At present, Jilin, Inner Mongolia, Anhui, Guangxi and other places in China have all had intensive injections, but because the intensive injection is somewhat different from the ordinary injection, and some people have swelling pain, muscle soreness and other conditions when using the ordinary injection, so many people do not know whether to do it, then how about the side effects of the enhanced injection of the new coronavirus vaccine?

Side effects of COVID-19 vaccine?

The side effects of the booster injection of COVID-19 vaccine are not significant, because after full research and demonstration by experts organized by the national vaccine research and development team, it is found that there is no serious adverse reaction after the booster injection, and it is still as safe as the first and second injections. Generally speaking, some vaccinated individuals may experience symptoms such as soreness, swelling, hardening, and itching at the injection site, similar to the first and second doses. Occasionally, they may also experience symptoms such as fever, headache, nausea, fatigue, and muscle soreness. However, these symptoms usually heal within 2-3 days, so there is no need to pay too much attention to them. In addition, some people who experience adverse symptoms such as coughing, vomiting, and diarrhea do not need special treatment, but if the symptoms are severe or cannot be judged on their own, they should seek medical attention in a timely manner and inform the vaccination doctor.

How effective is the COVID-19 vaccine booster?

After the enhanced immunization with the original vaccine for injection of COVID-19 vaccine, the neutralizing antibody level of the vaccinators rapidly increased significantly, up to 1-3 times. Although the antibody level declined six months later, the decline value was still higher than the peak value after two or one doses of inoculation, and the ability to resist various variants such as delta virus was enhanced.
