reporter learned from the Jinan Municipal Center for Disease Control and Prevention that as of 24:00 on May 23, Jinan has received a total of 22.9491 million doses of new coronavirus vaccine, covering 8.9237 million people, and 8.6913 million people have completed the full vaccination. The vaccination rate for people aged 3 and above is 99.90%, and the full vaccination rate is 97.30%. The vaccination rate of people aged 60 and above in the city is 84.40%.
"Crown vaccination is a key means to prevent COVID-19, and is crucial to preventing severe illness and reducing mortality. Citizens who meet the conditions are advised to receive the COVID-19 vaccine as soon as possible, and it is recommended that citizens who have completed the entire immunization for 6 months to strengthen their immunization." Zhao Xiaodong, director of the Immunization Prevention Institute of Jinan Municipal Center for Disease Control and Prevention, reminds the general public not to undergo nucleic acid tests within 48 hours after receiving the inactivated COVID-19 vaccine, which may lead to false positive tests.
Why can
nucleic acid cause "false positive" 48 hours after inactivated vaccine?
"This is mainly because the inactivated new coronavirus vaccine is prepared by wild virus through culture and inactivation processes. Although the virus has been inactivated, it still retains relatively complete viral nucleic acid fragments. During the vaccination process, the vaccine components will directly or indirectly contaminate the vaccination site, vaccinator and recipients in liquid or aerosol." According to Zhao Xiaodong, nucleic acid testing is very sensitive, and the residual components of the vaccine will cause positive test results. Therefore, within 48 hours after receiving the inactivated COVID-19 vaccine, do not enter the nucleic acid sampling area or sampling room, and do not undergo nucleic acid testing. If citizens really need to undergo nucleic acid testing, they must 48 hours after receiving the inactivated vaccine.
Zhao Xiaodong said that if there is a need for nucleic acid testing within 48 hours after receiving the COVID-19 vaccine, it is recommended to get the COVID-19 recombinant protein vaccine or adenovirus vector vaccine, because these two vaccines use recombinant protein technology and nucleic acid recombinant technology respectively, and do not include nucleic acid testing fragments, so there will be no positive nucleic acid test result. In addition, after the inactivated vaccine is administered throughout the whole process, it is strengthened with recombinant protein and adenovirus vector vaccine. After clinical trial verification, the effect is very good and very safe.
