Nucleic acids are not recommended immediately after booster shots.
Nucleic acid testing is recommended 48 hours after the booster shot. Most of the booster shots of New Crown vaccine belong to inactivated vaccine. The inactivated vaccine of New Crown virus is treated by inactivation and other preparation processes, the virus has lost its infectivity and pathogenicity, but still retains relatively intact nucleic acid fragments of the virus.
During the vaccination process, healthcare workers will cause the nucleic acid fragments of the vaccine to adhere to the surfaces of the inoculation table, walls, clothing of the inoculators and the inoculated subjects in the form of liquid or aerosol when opening the vaccine vials, extracting the vaccine liquid, and venting the air from the syringes, etc. The nucleic acid fragments of the vaccine will also adhere to the surfaces of the inoculation table, walls, clothing of the inoculators and the inoculated subjects.
When sampling for nucleic acid testing, it is very likely that the nucleic acid fragments of the virus carried on the body are sampled before they are degraded, and the nucleic acid testing used in our country is the polymerase chain reaction, which has a high degree of sensitivity, and may lead to false-positive nucleic acid test results.
If you need to do nucleic acid after a booster shot, please inform your healthcare provider in a timely manner, and report any suspected symptoms to your community in a timely manner.
