A small percentage of people may test positive for nucleic acid within a short period of time after receiving the New Crown vaccine, and most people will have no effect on the nucleic acid test results after receiving the New Crown vaccine. It is currently recommended that nucleic acid testing should not be performed within 48 hours after vaccination, when false-positive results may occur due to the recent administration of the new coronary vaccine. However, this is not the case for all vaccinated patients, and the majority of vaccinated patients will have no effect on the results of the nucleic acid test. To avoid false positives, the nucleic acid test can be performed 48 hours after vaccination, when the results are more accurate and reliable.
