I've already had the vaccination, why do I have to take a nucleic acid test? If you have a vaccination record, you don't need to take a nucleic acid test anywhere, right? If you don't have the nucleic acid test, it's still the same if you have the vaccination certificate, right?
Since the new vaccine was introduced, the most important concern of those who come to me is whether they need to do nucleic acid testing after receiving the vaccine, in addition to the vaccine.
In fact, everyone's thoughts, I also understand. After all, the new crown epidemic is still spreading around the world, for safety reasons, many high-risk industries, such as the medical sector, logistics industry and often travel friends, need to do nucleic acid testing, time-consuming and expensive, not to mention the kind of soreness of doing the test, really who do who know! So, is it just like what everyone thinks?
So, is it true that we don't need to do the nucleic acid test if we have already received the new vaccine?
I regret to tell you.
No.
New Crown vaccination record
The Nucleic Acid Test is not a substitute for a negative Nucleic Acid Test.
We still have to do it. First of all, I would like to introduce you to
Nucleic acid testing principle
All living organisms contain nucleic acids, including deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), the new coronavirus is a virus containing only RNA, the specific RNA sequence in the virus is a marker to distinguish the virus from other pathogens.
After the emergence of the novel coronavirus, our scientists completed the whole genome sequence analysis of the novel coronavirus in a very short time, and discovered the specific nucleic acid sequence in the novel coronavirus by comparing with the genome sequences of other species.
The most common method for detecting novel coronavirus-specific sequences is fluorescent quantitative PCR (polymerase chain reaction). The fluorescence PCR instrument is able to monitor the number of cycles of fluorescence reaching a predetermined threshold (Ct value) in relation to the viral nucleic acid concentration, the higher the viral nucleic acid concentration, the smaller the Ct value.
Different manufacturers' products will determine the positive judgment value of this product based on the performance of their own products. During clinical laboratory testing, if the specific nucleic acid sequence of a novel coronavirus can be detected in a patient sample, it should indicate that the patient may be infected by a novel coronavirus. Therefore, the new coronavirus nucleic acid test is an effective method to determine whether a patient is infected with a novel coronavirus by detecting the presence of a novel coronavirus-specific nucleic acid sequence in the patient's sample.
Then, let's learn more together about
Basic information about the new coronavirus vaccine
Novel coronavirus vaccine (2019-nCoV vaccine), a vaccine against novel coronavirus. on December 31, 2020, the joint prevention and control mechanism of the State Council was released, and the new inactivated coronavirus vaccine of Sinopharm Group China has been approved by the State Drug Administration with conditions for marketing. on February 25, 2021, Conchino Biological Joint Stock Company and the Military Medical Research Institute of the Academy of Military Sciences The recombinant novel coronavirus vaccine (Adenovirus type 5 vector) (Ad5-nCoV) KvisaTM, which was developed in cooperation with the Institute of Biological Engineering of the Military Academy of Sciences, was approved by the State Drug Administration for conditional marketing.
The advantages of inactivated vaccine are its traditional and classic preparation method, mature and reliable means of R&D and production. Compared with other technical routes, inactivated vaccine has a mature R&D platform, stable production process, controllable quality standards, good protection effect, and easy to produce on a large scale, with internationally accepted safety and efficacy evaluation standards.
Recombinant novel coronavirus vaccine, a single-dose new coronavirus vaccine approved for conditional marketing, single-dose vaccination can quickly achieve immune protection and shorten the vaccination cycle, and this single-dose vaccination regimen will achieve herd immunity in a shorter period of time.
Once the basics are mastered, then the question arises!
Will I test positive for nucleic acid after receiving the new crown vaccine?
No, you do not have to worry about this.
So far, the new coronavirus vaccine approved for domestic use is either a domestic inactivated new coronavirus vaccine or a recombinant new coronavirus vaccine, which is not a live attenuated vaccine, so the new coronavirus vaccine used now is a "killed" pathogenic microorganism or part of a pathogenic microorganism. Therefore, the vaccine is a part of the "killed" microorganism or pathogenic microorganism, which is not infectious or replicative, so it will not cause neocoronavirus pneumonia after vaccination, nor will it cause a positive nucleic acid test for neocoronavirus after vaccination.
So, does vaccination mean that everything is safe?
Does it mean that you can't get the Neoplastic virus?
Unfortunately, no. According to published clinical studies, antibodies generally start to develop 7 days after the first dose, and the antibody positivity rate is about 60%-90% in 14-28 days; the antibody positivity rate is more than 90% after 28 days of the second dose, and continuous protection is formed, and the current evidence suggests that the protection period of inactivated neo-coronavirus vaccine can reach at least half a year. According to the results of the phase III clinical trial interim analysis data of the recombinant novel coronavirus vaccine, the overall protective efficacy of the vaccine against all symptoms was 65.28% after 28 days of single-dose vaccination and 68.83% after 14 days of single-dose vaccination; the protective efficacy against severe disease was 90.07% after 28 days of single-dose vaccination and 95.47% after 14 days of single-dose vaccination, respectively. Of course, the discovery of the new crown virus is still relatively short, and the persistence of immunity for the new crown vaccine is still under continuous observation. U summarize for you.
Vaccination with the neo-crown vaccine gives us an added layer of protective armor against neo-crown virus, but it does not mean that we will definitely not be infected with neo-crown virus.
Therefore, the certificate of vaccination for Neoconazole vaccine ≠ the certificate of exemption from nucleic acid testing, because there is still a risk of infection after vaccination.
Because of this, other protective measures such as wearing a mask, washing hands regularly, and other measures are also necessary!
