D, Inhibition of SARS-CoV-2 RBD–hACE2 interaction by sera from patients with COVID-19. F, Inhibition of SARS-CoV RBD–hACE2 interaction by sera from patients with SARS. The data presented are the mean of two independent experiments.

  1. The first type is the conventional virus neutralization test (cVNT), which detects neutralizing antibodies (NAbs) in a patient’s blood.
  2. The data presented are the mean of two independent experiments.
  3. It can also be used to assess vaccine efficacy during preclinical and clinical trials of different vaccine candidates and to monitor neutralizing titers in vaccinees after mass vaccination in human populations.
  4. The differences between negative control and COVID-19 test sera were analyzed using an unpaired t-test.
  5. The assay was performed in two different countries by two independent groups to further ensure reliability and reproducibility.

The major advantage of sVNT is that it can be rapidly conducted in most research or clinical laboratories without the need to use live biological materials and biosafety containment. The sVNT is also amenable to high-throughput testing and/or fully automated testing after minimal adaptation. This website is using a security service to protect itself from online attacks.

Here, we report a SARS-CoV-2 surrogate virus neutralization test that detects total immunodominant neutralizing antibodies targeting the viral spike (S) protein receptor-binding domain in an isotype- and species-independent manner. Our simple and rapid test is based on antibody-mediated blockage of the interaction between the angiotensin-converting enzyme 2 (ACE2) receptor protein and the receptor-binding domain. The test, which has been validated with two cohorts of patients with COVID-19 in two different countries, achieves 99.93% specificity and 95–100% sensitivity, and differentiates antibody responses to several human coronaviruses. The surrogate virus neutralization test does not require biosafety level 3 containment, making it broadly accessible to the wider community for both research and clinical applications.

Similarly, sera from ferrets infected with SARS-CoV and rabbits immunized with inactivated SARS-CoV also display an efficient dose-dependent inhibition of the interaction between hACE2 and the SARS-CoV RBD in the SARS-CoV sVNT (Fig. 3b). Immediately after SARS-CoV-2 was identified as the causative agent of the COVID-19 outbreak, it was shown that human ACE2 (hACE2) is the main functional receptor for viral entry3. We hypothesized that the virus–receptor binding can be mimicked in vitro via a protein–protein interaction using purified recombinant hACE2 and the RBD of the SARS-CoV-2 S protein. This interaction can be blocked by virus NAbs present in the test serum, using the same principle as cVNT conducted using live virus inside a BSL3 facility (Fig. 1a,b).

Discussion and debate on the role of serology have intensified greatly in this context6.

The company’s whitepaper and the project’s website are written in Chinese, not English. Although its Twitter profile is in English, CVNT hasn’t posted anything there for well over a year. While CVNT could have a lot bigger following in China, it doesn’t bode well for a prominent crypto project looking for international attention to not have an English-translated whitepaper and website. Of the total possible supply of 1,000,000,000 CVNT, the current circulating amount is -.

Potently neutralizing and protective human antibodies against SARS-CoV-2

Finally, we have found that the N-specific antibody level is much lower in the 2020 SARS sera than in the 2003 samples (Fig. 3f). The results obtained from the two SARS serum panels of 17 years apart are notable. The presence of long-lasting NAbs 17 years after the initial infection is encouraging news for patients who have recovered from COVID-19, considering the close relationship between the two viruses. In summary, we have addressed the challenge of COVID-19 serology with an approach that enables the detection of NAbs in an easy, safe and rapid manner with enhanced specificity and sensitivity. Although the sVNT assay may never be able to completely replace cVNT, our data indicate that the performance of sVNT is well correlated with that of both cVNT and pVNT. Its application can cover many aspects of COVID-19 investigation from contact tracing, seroprevalence surveying and reservoir/intermediate animal tracking to the assessment of herd immunity and longevity of protective immunity.

All other assays, such as enzyme-linked immunosorbent assay (ELISA) and lateral flow assay (LFA) rapid tests, represent the second assay type, which detects total binding antibodies (BAbs) and is unable to differentiate between BAbs and NAbs6,9,10. The data presented here demonstrated that sVNT is as specific as, but more sensitive than, cVNT in the cell types tested here (Fig. 4). In our initial optimization studies, we found that the RBD protein performed better than the S1 protein (Extended Data Fig. 1).

However, studies based on both SARS-CoV and SARS-CoV-2 suggest that the RBD-targeting NAbs are immunodominant during both SARS and COVID-19 infections19,20. In our study, we used 60 patient serum samples of varying NAb levels, and the 3-way correlation studies presented in Fig. 4 clearly demonstrate that the correlation between sVNT and cVNT is as good as, if not better than, that between pVNT and cVNT. This indicates that non-RBD-targeting antibodies, which could be measured in pVNT, but not in sVNT, are unlikely to play a major role in SARS-CoV-2 neutralization, consistent with previous findings19,20,21. A robust serological test to detect neutralizing antibodies to SARS-CoV-2 is urgently needed to determine not only the infection rate, herd immunity and predicted humoral protection, but also vaccine efficacy during clinical trials and after large-scale vaccination. The current gold standard is the conventional virus neutralization test requiring live pathogen and a biosafety level 3 laboratory.

Research laboratories and pharmaceutical companies are racing to produce antibody tests that can detect COVID-19 infection with sufficient specificity and sensitivity6. The first type is the conventional virus neutralization test (cVNT), which detects neutralizing antibodies (NAbs) in a patient’s blood. The cVNT content value network cvnt requires handling live SARS-CoV-2 in a specialized biosafety level 3 (BSL3) containment facility and is tedious and time-consuming, taking 2–4 days to complete. The pseudovirus-based VNT (pVNT), on the other hand, can be performed in a BSL2 laboratory, but still requires the use of live viruses and cells7,8.

In this study, we established a surrogate VNT (sVNT) that detects NAbs, without the need for any live virus or cells, that can be completed in 1–2 h in a BSL2 laboratory. Using purified receptor-binding domain (RBD) from the S protein and the host cell receptor ACE2, our test is designed to mimic the virus–host interaction in an ELISA plate well. This RBD–ACE2 interaction can be neutralized (that is, blocked) by specific NAbs in patient or animal sera, in the same manner as in cVNT or pVNT. Although many COVID-19 laboratory-based or point-of-care antibody test kits are commercially available, none is capable of measuring NAbs.
