Q: Is it still necessary to take a COVID-19 nucleic acid test if I get vaccinated?

A: A COVID-19 vaccination certificate does not play the same role as a nucleic acid test report. During the epidemic, people ought to collaborate with the authority to conduct nucleic acid tests in light of the following facts:

First, no vaccine can provide full (100%) protection. Even though you are vaccinated, the vaccine may still fail to have a preventative effect on you. In that case, you may be infected and tested positive in case of being exposed to the VOCID-19 virus.

Second, it will take some time for the vaccine to have a preventative effect on you after you were vaccinated. If you got infected before it even has an effect, you may be tested positive.

Third, you may have been infected before you got vaccinated. In the virus incubation period or when you are asymptomatic with infections, you may be tested positive. Therefore, even though you have completed your vaccination schedule, you still need to conduct a nucleic acid test.

Q: Do I need to get vaccinated if I had been infected?

A: Existing data shows that people seldom get infected again within six months since he/she was infected with COVID-19. Therefore, you could start your vaccination schedule six months later after you were infected (confirmed or asymptomatic), based on full complete understanding and willingness.
