The current general rule is that new coronavirus nucleic acid testing cannot be performed within 48 hours of receiving the new coronavirus vaccine, so new coronavirus nucleic acid testing can be performed within 72 hours of receiving the new coronavirus vaccine, if it is more than 48 hours. The new vaccines include the new inactivated coronavirus vaccine (Vero cell), recombinant new coronavirus vaccine (adenovirus vector type 5) and recombinant new coronavirus vaccine (CHO cell), which are vaccines developed for the new coronavirus. Generally, if nucleic acid testing is needed after the new coronavirus vaccination, please allow at least 48 hours for the test to avoid false-positive nucleic acid test results. Within 72 hours of receiving the new coronavirus vaccine, if 48 hours have not yet elapsed, if it is necessary to perform the new coronavirus nucleic acid test, you should also take the initiative to inform the staff of the recent new coronavirus vaccination to avoid any unnecessary impact.
