Quantification of Binding and Neutralizing Antibody Levels in COVID-19 Vaccinated Health Care Workers Over 1 Year
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic presents a great challenge to global health. The first case was identified in December 2019 in Wuhan, China and since has infected nearly 100 million people and claimed almost 2 million lives worldwide. In response, the medical community and scientists have worked hard to develop effective therapies and guidelines to treat a wide range of symptoms including the use of the antiviral drug remdesivir, convalescent plasma, antibiotics, steroids, and anticoagulant therapy. To prevent the spread of the disease, multiple vaccines based on mRNA and DNA technologies that include inactivated viral components have been developed and millions of doses are currently being administered worldwide. Early analysis of data from the phase III Pfizer/BioNTech and Moderna vaccine trials suggested the vaccine was more than 90% effective in preventing the illness with a good safety profile (Polack et al., 2020). However, there are still many unknowns regarding the long-term safety of these newer vaccine technologies and the level and duration of immunogenicity.
SARS-CoV-2 infection results in seroconversion and production of anti-SARS-CoV-2 antibodies. The antibodies may suppress viral replication through neutralization but might also participate in COVID-19 pathogenesis through a process termed antibody-dependent enhancement (Lu et al., 2020). Rapid progress has been made in the research of antibody response and therapy in COVID-19 patients, including characterization of the clinical features of antibody responses in different populations infected by SARS-CoV-2, treatment of COVID-19 patients with convalescent plasma and intravenous immunoglobin products, isolation and characterization of a large panel of monoclonal neutralizing antibodies and early clinical testing, as well as clinical results from several COVID-19 vaccine candidates.
In this study, we plan to assess the effic of both vaccines on the healthcare workers. As healthcare workers begin to receive their first vaccination dosage, we will start looking for traces of antibodies within the blood and saliva. The data provided will help us determine the efficacy of the vaccine over a period of 1 year, identify any difference in efficacy amongst different populations (gender, age, and ethnicities) differences among vaccine types, demographics and follow-up on any potential side effects. We will collaborate with Nirmidas Biotech Inc. based in Palto Alto, California, a Stanford University spinoff on this project. Nirmidas Biotech. Inc is a young diagnostic company that have received several FDA EUA tests for COVID-19. We will perform IgG/IgM antibody detection by the NIRMIDAS MidaSpot™ COVID-19 Antibody Combo Detection Kit approved by FDA EUA for POC testing in our hospital site for qualitative antibody testing. We will then send dry blood spot and saliva to Nirmidas for the pGOLD™ COVID-19 High Accuracy IgG/IgM Assay to quantify antibody levels and avidity, both of which are important to immunity. The pGOLD assay is a novel nanotechnology assay platform capable of quantifying antibody levels and binding affinity to viruses. We collaborated recently with Nirmidas on this platform and published a joint paper in Nature Biomedical Engineering on COVID-19 Ab pGOLD assay (Liu et al., 2020). It is also capable of detecting antibodies in saliva samples and could offer a non-invasive approach to assessing antibody response for vaccination.
