The question refers to the booster shot and the nucleic acid test for the new coronavirus, which can be done 48 hours after the booster shot. Nucleic acid test can be done 48 hours after the booster shot, because the new crown vaccine booster shot is more inactivated new crown vaccine, and the new crown virus inactivated vaccine is prepared by the new crown wild virus through culture, inactivation and other processes, after vaccination, although the virus has lost its infectivity and pathogenicity, but there is still a nucleic acid fragment of the new crown virus. In the inoculation process may cause the nucleic acid fragments of the virus to be suspended in the air and form an aerosol, which in turn leads to residues on the skin and other parts of the body, resulting in false-positive nucleic acid results. In addition, the nucleic acid test looks for the presence of nucleic acids from foreign invading viruses in the patient’s respiratory specimen, blood or feces to determine whether the patient is infected by the new coronavirus, and performing the nucleic acid test immediately after the booster vaccination may result in an inaccurate nucleic acid test result. If there is an emergency that requires nucleic acid testing after booster vaccination, please take the initiative to inform us of the recent booster vaccination information to avoid unnecessary impact.
