Vaccination in this context usually refers to the new crown vaccine, which cannot be tested for nucleic acid after it has been administered because of the possibility of false positives.
If the inactivated virus vaccine is injected, the vaccine contains the nucleic acid sequence of the virus, which may contaminate the nasal cavity of the vaccinated person or the presence of the nucleic acid fragments of the Neo-Crown virus in the pharyngeal mucosa in the form of a liquid or aerosol during the vaccination process, and a false positive result may occur in the detection of nasopharyngeal secretions. It is recommended that nucleic acid testing be performed 48 hours later so that the likelihood of false positives is minimized.
