It is best not to do nucleic acid testing for 48 hours when vaccinating with Neocoronavirus vaccine because the vaccine may produce aerosols that can interfere with nucleic acid test results; there is no time limit if other types of vaccines are administered.
Since the vaccine is made after the inactivation of the New Crown virus, the nucleic acid fragments of the New Crown virus are still present. When the New Crown vaccine is administered, the vaccine may be present in the form of liquid or aerosol in the vaccination site, and it is possible that the vaccine may be inhaled, and even though the inactivated New Crown vaccine virus that is inhaled does not have a pathogenic effect, it retains nucleic acid fragments of the virus, which may still be detected by nucleic acid testing and lead to a positive result.
Therefore, it is best not to test for nucleic acid within 48 hours after vaccination, as the nucleic acid fragments will degrade after 48 hours and the results will be more accurate.
Other vaccines do not have nucleic acid sequences associated with NeoCornea, so nucleic acid testing can be done at any time after vaccination with other vaccines.
Other precautions to be taken before performing the nucleic acid test are related to the sampling method at the site, and it is recommended to follow the requirements at the site for the test.
