There are many kinds of vaccinations, if you are vaccinated with XKV vaccine, you need to wait 48 hours before you can do the nucleic acid test; however, if you are vaccinated with Hepatitis B vaccine, rabies vaccine, tetanus vaccine and so on, you will not be affected. 1. Nucleic acid test is not allowed: the new crown vaccine is specially prepared and only retains its antigenicity, and vaccination with the new crown vaccine can stimulate the human body to produce antibodies with a protective effect. When the body has not metabolized the vaccine completely within 48 hours after vaccination, the nucleic acid contained in the residual vaccine can lead to a false-positive nucleic acid result. 2. Nucleic acid test can be done: patients who have been vaccinated with hepatitis B vaccine, rabies vaccine, tetanus vaccine, etc. for the prevention of hepatitis B, rabies and tetanus. There is no special effect on the new coronavirus test, and there is no conflict between the above vaccines and the nucleic acid test. You need to consult with your physician at the time of vaccination, and the physician will choose whether or not to do the nucleic acid test according to the situation.
