Is it still used for nucleic acid test after the third injection of COVID-19? Is it normal to report positive after COVID-19 vaccination

Do you still need nucleic acid test after COVID-19 vaccination

Nucleic acid test is also required after COVID-19 vaccination. Nucleic acid detection is very important for the detection of COVID-19. When its result shows positive, it indicates that there is COVID-19 in the body.

Whether nucleic acid test is negative or positive after inoculation of COVID-19 vaccine

The purpose of injecting novel coronavirus vaccine is to inject inactivated novel coronavirus (a virus that has no ability to cause disease, that is, a virus that has died) into the human body, stimulate the body to produce antibodies with resistance, and nucleic acid test is negative after injection of vaccine.

Is it normal to report positive after COVID-19 vaccination

abnormal, which may be caused by the following reasons:

1. After full vaccination, some people are not effectively protected due to immune failure, and after this part of the population is exposed to COVID-19, they may be detected positive for nucleic acid or become ill due to COVID-19 infection.

2. It takes some time after vaccination to produce protective effects. If you are infected with COVID-19 during this period, you may detect positive nucleic acid or disease.

3. Patients in the latent period of the disease or asymptomatic carriers may still test positive for nucleic acid or develop symptoms due to being infected, even if vaccinated.

Do you need to be isolated when you come back from abroad after the vaccination of COVID-19 Vaccine

Yes. As long as the epidemic situation is not completely over, even if there is an injection of COVID-19 vaccine, isolation is required after returning from abroad. Because so far, no vaccine can achieve 100% protective effect, and a small number of people still do not receive protection after vaccination. Therefore, even if there is COVID-19 vaccination, we should continue to do a good job of personal protection in the later period. In addition, if you go to areas with medium to high risk, you must undergo self isolation after returning.
