Peripheral blood samples were centrifuged at 400, To detect possibly neutralizing or probably neutralizing antibodies (nAb) against SARS-CoV-2, the SARS-CoV-2 NeutraLISA test (Euroimmun, Lbeck, Germany) was utilized as a surrogate neutralization antibody (snAb) assay according to the manufacturers instructions. Investigators followed 1960 health care workers from Johns Hopkins Medicine who received both doses of either the Moderna or Pfizer vaccination, including 73 individuals who tested positive for COVID-19 before their first dose. By entering your email and clicking Sign Up, you're agreeing to let us send you customized marketing messages about us and our advertising partners. But this rate decreased to 70 percent after eight years. Antibody tests fail to measure the second, very important arm of the immune system: the T-cells (which clear infected cells and help prevent an infection from becoming severe) and B-cells (which produce new antibodies targeting the variant upon exposure). There is still not a really robust correlate of immunity, meaning a level of antibody where if youre above that level we can confidently say, yes, this person is protected, Ratner said. doi: 10.1016/S2665-9913(22)00330-7. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. They prompt other immune system cells to eliminate foreign substances. However, it doesn't prove that there has been no prior or current infection. Along with diabetes and cardiovascular disease, suppressed immunity is also the most significant risk factor for lower spike antibody titers after the first dose. If there is still an inadequate response, these people will require immunoglobulin for protection if exposed to hepatitis B. EurekAlert. The general consensus among infectious diseases specialists is that its far too early for people to be making serious decisions off of antibody tests results. But a new Northwestern Medicine study shows the antibodies . We observed that the combination of infection plus vaccination, regardless of infection . Blood samples were taken between 7 and 21 days after each vaccination. On the day of collection, all peripheral blood samples were transferred to the laboratory and processed. This is consistent with results from previous studies that also showed that gammaglobulin levels or cumulative RTX dose did not influence antibody response.2 Altogether, these results strongly support including the assessment of B cell reconstitution and SARS-CoV-2 spike antibodies into clinical decisions on timing of booster doses in RTX-treated patients, although it is still not currently incorporated into European Alliance of Associations for Rheumatology or American College of Rheumatology guidelines (Figure). Part of HuffPost Wellness. What does it mean? All rights reserved. This research included participants for the third vaccine dosage with a median of 151 (IQR [Inter Quartile Range 2575 percentiles]: 108161) days following the second vaccination dose. Moreover, humoral response was highly heterogeneous in the 23 included studies, with a rate of responders ranging from 0 to approximately 80%.3 These results must be put in perspective with the probable conservation of a functional T cell response in RTX-treated patients. Endocrinology (including Diabetes Mellitus and Metabolic Disease), Intensive Care and Critical Care Medicine, Rehabilitation Medicine and Physical Therapy. Once plasmablasts. Sign In to Email Alerts with your Email Address. Since natural infection increases the formation of memory B cells, the host immune response may become more robust [. ; et al. Blood samples were taken just before the third vaccination (0th). There are also antibody tests that measure antibodies against the spike protein (which is what the vaccines are designed to teach our immune system to attack) and others that measure antibodies against an element called the nucleocapsid (which are helpful in identifying if someone previously had COVID-19, but they fall short at detecting antibodies in someone whos only been vaccinated). Enter an organism name (or organism group name such as enterobacteriaceae, rodents), taxonomy id or select from the suggestion list as you type. https://www.mdpi.com/openaccess. Levels between 10 and 1000 are considered protective. JA has received honoraria from AstraZeneca. News-Medical. Vaccination against SARS-CoV-2 has been a major step forward to protect immunocompromised patients from severe clinical outcomes. ; Garca-Rivera, C.; Caballero, P.; Gabaldn-Bravo, E.M.; Rodrguez-Diaz, J.C.; Hurtado-Snchez, J.A. Antibody testing is currently not recommended to assess for immunity to SARS-CoV-2 following COVID-19 vaccination. Intensive vaccination is recommended for populations more vulnerable to COVID-19 infection, although data regarding the built of immunity after vaccination for dialysis patients are lacking. Entrez query (optional) Help. First, B cell reconstitution has a critical role in influencing the response to the vaccine. This site complies with the HONcode standard for trustworthy health information: verify here. During each blood draw, a Panbio COVID-19 (Abbott, IL, USA) fast antigen test kit was used according to the manufacturers instructions to detect active SARS-CoV-2 infection in the subjects. But if that minimum level of protection is only an antibody titer of 10 or 50, both of those. The IgG levels were reported as binding antibody units (BAU)/mL. Individuals who were infected 90 days before initial vaccination had adjusted antibody levels 9% higher at 1 month and 13% higher at 3 months than those infected less than or equal to the 90-day mark, she said. Note that from the first issue of 2016, this journal uses article numbers instead of page numbers. But that's just one study, and we need many more. 1996-2023 MDPI (Basel, Switzerland) unless otherwise stated. In this interview, we speak to Ceri Wiggins, a Director at AstraZeneca, about the many applications of CRISPR and its role in discovering new COPD therapies. Using a multiplex bead-binding assay (Milliplex SARS-CoV-2 Antigen Panel 1 IgG, Millipore) that measures levels of IgG against SARS-CoV-2 . Age, gender, and comorbidities were used to conduct a complete evaluation. After the second vaccine dose IgG levels increased further, reaching a maximum approximately 7-10 days later, and remained elevated (average of 58% peak levels) during the additional >100 day follow up period. However, this does not have an obvious clinical impact in terms of the number of severe infections or death. This prospective, observational cohort study of maintenance hemodialysis patients examined IgG antibody level This could be because T lymphocytes come into play even while the spike antibody responses to ChAdOx1 are lower than BNT162b2, and this is responsible for the observed comparable efficacies of both vaccines. Likewise, this study found no difference between patients with or without prior SARS-CoV-2 infection [, Cassaniti et al. The course of antibody titers following vaccination in RTX-treated patients needs to be precise because it may influence the time of vaccine booster. 2021 Oct 30;10(21):5113. doi: 10.3390/jcm10215113. Several questions are still pending and will need to be considered. This was due to a faster decline in antibody levels, indicating a significantly reduced duration of vaccination-induced immunity compared to HC or patients receiving csDMARDs. In general, the more antibodies, the better, Wells said. Similarly, the reduced activation of T helper lymphocytes could be partly responsible, at least, for the poor antibody response following vaccination of immunocompromised individuals. The site is secure. The original vaccinations for COVID-19 induce potent antibodies that protect against SARS-CoV-2. In addition, they do not know the variant type or timing of SARS-CoV-2 variants previously encountered. In this prospective longitudinal study, 300 healthy persons were recruited to participate at random after two doses of BNT162b2 immunization and prior to a third dose administered between January and February 2022. Spike antigen-specific IgG levels rose exponentially and plateaued 21 days after the initial vaccine dose. They also found that anti-S-RBD antibody levels fell to a steady state after four months, and anti-S-RBD IgG levels were independent of age, gender, vaccine doses, and baseline antibody titer [, After the third dosage of the BNT162b2 vaccine, Kontopoulou et al. News-Medical, viewed 01 March 2023, https://www.news-medical.net/news/20210519/Spike-antibodies-after-vaccination-with-Pfizer-and-Oxford-vaccines.aspx. Significant protection, at 57%, is seen against symptomatic infection from 14 days onwards. Even if you check an antibody quantitatively and tell me your number, I dont know what to tell you is it enough, is it going to protect you, is it too low? , a Yale Medicine infectious diseases specialist. Cheetham NJ, Kibble M, Wong A, Silverwood RJ, Knuppel A, Williams DM, Hamilton OKL, Lee PH, Bridger Staatz C, Di Gessa G, Zhu J, Katikireddi SV, Ploubidis GB, Thompson EJ, Bowyer RCE, Zhang X, Abbasian G, Garcia MP, Hart D, Seow J, Graham C, Kouphou N, Acors S, Malim MH, Mitchell RE, Northstone K, Major-Smith D, Matthews S, Breeze T, Crawford M, Molloy L, Kwong ASF, Doores K, Chaturvedi N, Duncan EL, Timpson NJ, Steves CJ. Experts can't agree on whether to use COVID-19 antibody tests to check whether people need a booster shot. Anti-SARS-CoV-2 IgG and Neutralizing Antibody Levels in Patients with Past COVID-19 Infection: A Longitudinal Study. Lu, L.; Chen, L.-L.; Zhang, R.R.-Q. ; Papazisis, G. Significant Increase in Antibody Titers after the 3rd Booster Dose of the Pfizer-BioNTech mRNA COVID-19 Vaccine in Healthcare Workers in Greece. Evusheld is administered as two injections into the buttocks during one appointment. 2023; 11(3):560. In somebody who is immunocompromised, their antibody titer might be only 100. This percentage of positive serological response was higher than those observed in previous series, including the largest of 62 patients, in which only 9 (14.5%) patients seroconverted following a third dose.9-11 Several factors may at least partly explain these discrepancies, including a population that had a majority of patients being treated for antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, whereas most other studies had a majority of patients with rheumatoid arthritis (RA). DOI: 10.1016/j.celrep.2023.112167. The copyright holder for this preprint is the author/funder, who has granted medRxiv a license to display the preprint in perpetuity. In this study of the humoral response to 2 doses of mRNA SARS-CoV-2 vaccine among solid organ transplant recipients, the majority had detectable antibody responses after the second dose, although participants without a response after dose 1 had generally low antibody levels. In, Aleem, A.; Akbar Samad, A.B. The Advisory Committee on Immunization Practices (ACIP) recommends that the following people should receive hepatitis B vaccination: All infants Unvaccinated children aged <19 years Adults aged 19 through 59 years Adults aged 60 years and older with risk factors for hepatitis B The following groups may receive hepatitis B vaccination: The extent of B cell reconstitution and time from last RTX may also account for these differences, but, unfortunately, these parameters were often not measured or discussed in the different studies. SARS-CoV-2-reactive IgG antibody monitoring and compliance. Early reports suggested that people who tested positive for antibodies after either a known or asymptomatic infection had some level of immunity. In addition, the participants median age was 32.5 (IQR: 2438) (, Anti-S-RBD IgG levels increased 5.94-fold on day 15, 3.63-fold on day 60, and 2.33-fold on day 90 after the third BNT162b2 vaccine dosage compared to pre-vaccination values (Day 0). Feature papers represent the most advanced research with significant potential for high impact in the field. If you are in crisis or having thoughts of suicide, Interestingly, the immunologic findings in the current study do not reflect real-life differences in vaccine efficacies between the two vaccines at 2-8 weeks. Hit enter to expand a main menu option (Health, Benefits, etc). They reported that they did not detect any difference between men and women. SARS-CoV-2 NCP IgG and anti-S-RBD IgG levels were detected by the CMIA method, and a surrogate neutralizing antibody was seen by the ELISA method. To access the menus on this page please perform the following steps. Lancet Rheumatol. The authors confirmed that detectable B cells and time from last RTX exposure > 6 months were also strongly associated with a positive response following a booster vaccine. The study was also supported by Anhui Postdoctoral Scientific Program (D.T.). ; Karaali, R.; Tok, Y.T. At this point, experts largely agree that antibody tests may be most useful for determining prior infection and identifying if an immunocompromised person mounted an immune response to the first round of shots or after the booster, Gandhi said. Spike antibodies after vaccination with Pfizer and Oxford vaccines. As the antibody level against Omicron BA.5, BF.7, and XBB 1.5 of the individuals has highly positive correlation with the antibody level against prototype SARS-CoV2, the IgG level specific to the prototype SARS-CoV-2 spike RBD could also represent the IgG level against Omicron variants. Study reveals synergistic impact of estrogen and intestinal dysbiosis on pulmonary fibrosis, Exploring the neuroprotective potential of cell-penetrating peptides, extracellular vesicles, and micro ribonucleic acids. Sasso, B.L. Investigators adjusted the study for age, gender, and vaccine type. Fifteen days, sixty days, and ninety days following the third immunization dose, blood samples were taken for follow-up. But this rate . ; DesignM.G.E., M.D., O.U., S.B. These cells are trained to produce antibodies to specific threats like the coronavirus after they are first. Modeling studies corroborate the findings of the current study. https://doi.org/10.3390/vaccines11030560, Erdem MG, Unlu O, Buber S, Demirci M, Kocazeybek BS. ; Demonbreun, A.R. In this longitudinal prospective study, 300 healthy persons were randomly included between January and February 2022, following two doses of BNT162b2 immunization and before a third dosage. ; Goodwin, B.; Rubiro, P.; Sutherland, A.; Wang, E.; et al. * 3 to 6 months following the last dose of vaccine. A surrogate virus neutralization test to quantify antibody-mediated inhibition of SARS-CoV-2 in finger stick dried blood spot samples. 1. Antibodies are important for a vaccination to work, but scientists don't yet know what level they must reach. By continuing to browse this site you agree to our use of cookies. She has counseled hundreds of patients facing issues from pregnancy-related problems and infertility, and has been in charge of over 2,000 deliveries, striving always to achieve a normal delivery rather than operative. Can the gut microbiota and metabolome explain variation in anti-SARS-CoV-2 vaccination responses in immunosuppressed IBD patients? The authors declare no conflict of interest. David Lat, a legal writer in Manhattan, had Covid-19 and then was vaccinated. The REACT2 study showed only 84% seroconversion after a single dose of the Pfizer vaccine, perhaps due to the use of a different assay. , they are gradually replaced by higher-quality antibodies, suggesting that eventually, it takes fewer antibodies to stay protected. ; Xu, X.; et al. Clipboard, Search History, and several other advanced features are temporarily unavailable. If no clinical signs of Lyme disease are observed, different approaches can be tried: (1) A different antibiotic can be used, (2) treatment time can be extended, or (3) the animal is not treated again but its antibody status is monitored every 6-12 months (depending on risk of new infection). The purpose of post-vaccination testing is to confirm if patients have achieved adequate immune response as measured by hepatitis B surface antibody Perform testing 1-2 months after final dose of the HBV vaccine series Persons with HBsAb concentrations of >10 mIU/ml are considered immune Post-vaccination testing is recommended for some patients: Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for reported that the wild-type virus provides a five-fold greater level of neutralizing antibodies one month after vaccination . ; Sirekbasan, S.; Akta, A.N. But even with a low level of antibodies months after exposure or receiving a vaccine, the body can mount a stout defense against the virus by generating new antibodies in response to a fresh infection. In the study of Schultz et al,8 the higher percentage of patients who were able to seroconvert after a booster dose allowed for more accurate associations than what other studies have been able to accomplish with their low numbers of seroconverted patients. At seven days after the second dose, both vaccines produced 99% seroconversion and high spike antibody levels, at 250 U/ml in most cases. Even if you check an antibody quantitatively and tell me your number, I dont know what to tell you is it enough, is it going to protect you, is it too low? ; Gambino, C.M. The post-vaccination antibody response in patients with immune-mediated neuromuscular diseases under immuno-suppressive therapy has not been sufficiently verified. Report a . Study Design Go to Antibody tests also dont tell us the quality of the antibodies that they detect. ; Critical ReviewM.G.E., O.U., M.D., S.B. The COVID-19 pandemic has had disastrous impacts on a global scale which continue [. Older adults (80 years) have. ; Trisal, M.; Wimmers, F.; Sanyal, M.; Weidenbacher, P.A. Disclaimer/Publishers Note: The statements, opinions and data contained in all publications are solely While there was a moderate positive association between NCP IgG titer and nAb IH% level before the third vaccination dosage (day 0) (rs:0.511, Monitoring SARS-CoV-2 antibodies in the host is essential for determining the significance of these antibodies in avoiding illness and revising vaccination policy [, In longitudinal investigations examining the anti-S-RBD IgG level of the third BNT162b2 vaccination dosage, Lo Sasso et al. A negative result suggests that you haven't had a recent COVID-19 infection. The exclusion criteria were as follows: (I) age 18 or >50, (II) a history of comorbidities, and (III) a current infection. Furthermore, the 4th booster vaccination could induce a comparable antibody level against prototype, Omicron BA.5, BF.7, and XBB 1.5 variants in the patients with 2 or 3-dose vaccination and protect people from being infected. Because of that, we need to be very cautious of how we interpret antibodies waning over time, Ogbuagu said. Bethesda (MD): National Institute of Child Health and Human Development; 2006. have hearing loss, Infants born to women whose HBSAg status remains unknown, Health care personnel and public safety workers at risk for blood or body fluid exposure, Other immunocompromised persons such as hematopoietic stem-cell transplant patients or persons receiving chemotherapy. Although the immune response in the disease group was modest compared to the control group, in which antibody titers after the third vaccination ranged from 67.8 to 150,000 s/co (0.9 to 5,402.1 times higher than those before vaccination), the result indicated that a constant immune response was achieved under immuno-suppressive therapy. Thomas, Liji. Thomas, Liji. Moreover, both vaccines were included, as well as different dosing intervals. positive feedback from the reviewers. Gilbert and others are hunting for a number that corresponds to immunity against COVID-19. on this website is designed to support, not to replace the relationship and B.S.K.

For Keywords: Even if you check an antibody quantitatively and tell me your number, I dont know what to tell you is it enough, is it going to protect you, is it too low? News-Medical.Net provides this medical information service in accordance Such a figure - measured by a specific type of immune antibodies in a person - could show whether they had developed enough immunity from a vaccine . The first would be to postpone RTX therapy to improve immunogenicity, if the last RTX infusion was 6 months and in cases of stable and quiescent disease. articles published under an open access Creative Common CC BY license, any part of the article may be reused without ; DAquila, R.T.; McNally, E.M.; Velez, M.P. and B.S.K. Which test to use: If testing is needed following vaccination, use quantitated HBsAb only, Veterans Crisis Line: It's a monoclonal antibody treatment (not a vaccine) that provides antibodies to the COVID-19 virus for up to six months. That said, scientists have uncovered some important clues about antibody levels and the protection they provide against symptomatic infection. They also found that there were differences in. Conclusions: Patients receiving b/tsDMARDs have significantly reduced Abs and neutralizing antibody titers 6 months after mRNA vaccination against SARS-CoV-2. ; Analysis and/or InterpretationM.G.E., O.U., M.D., S.B. The research, published in the journal Science, may be the first . between patient and physician/doctor and the medical advice they may provide. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Four SARS-CoV-2 vaccine doses or hybrid immunity in patients on immunosuppressive therapies: a Norwegian cohort study. The FDA said on May 19 that antibody tests shouldn't be used to test . Image Credit: M-Foto/Shutterstock.com. Various serologic assays (whether commercial or "home grown") are used, and responses are often compared to . However, no difference could be observed at 56 days or beyond. How did people in Zimbabwe respond to drug-resistant tuberculosis alongside COVID-19. The, Food and Drug Administration stated in May. medRxiv preprint. The bulk of antibodies made after infection or vaccination come from short-lived cells called plasmablasts, and antibody levels fall when these cells inevitably die off. November 1, 2021. Both vaccines were found to have high efficacy against the SARS-CoV-2, in terms of preventing both infections and symptomatic disease. The team measured levels of antibodies in the blood before vaccination and then after each of the two vaccine doses. Over 83% of those on steroids or other immunosuppressants, including cancer chemotherapy and targeted therapy, were seropositive at 28 or more days from the first dose. Nevertheless, anti-SARS-CoV-2 NCP IgG levels were over 2.03 S/Co in 36 of 146 (24.7%) males previously infected with SARS-CoV-2. The Pfizer vaccine elicited a median titer of 41 U/mL at 28 days as well as 42 days, compared to 30 and 35 U/mL with the Oxford vaccine at these time points. Please let us know what you think of our products and services. ; Gonzlez-Facio, R.; Montelongo-Cruz, L.P.; Del Rio-Parra, G.F.; Garza-Herrera, M.R. 57% reduction The researchers found that across age and sex, antibody levels reduced by more than 50% within 6 months of the second vaccination. In addition, nAb IH% increased by 26% on the 15th day and decreased by two-fold on the 90th day compared to the 15th day. The details of the IRB/oversight body that provided approval or exemption for the research described are given below: Ethics committee of The First Affiliated Hospital of University of Science and Technology of China gave ethical approval for this work. In conclusion, these data suggest that the prototype SARS-CoV-2 booster vaccination helps induce a high level of antibody against prototype, BA.5, BF.7, and XBB 1.5 variants after Omicron infection. Although the immune response in the disease group was modest compared to the control group, in which antibody titers after the third vaccination ranged from . With the controversy surrounding the dosing interval for the Oxford Astra-Zeneca vaccine against coronavirus disease 2019 (COVID-19), a new preprint published on the pre-print server medRxiv* discusses the results of a study of antibody responses to the first and second dose of two currently available SARS-CoV-2 vaccines, Pfizer and Oxford.

Effect of a Third Dose of SARS-CoV-2 mRNA BNT162b2 Vaccine on Humoral and Cellular Responses and Serum Anti-HLA Antibodies in Kidney Transplant Recipients. The slightly lower seroconversion rates compared to the 97% and 99% rates reported at 14 or more days from one dose of the Oxford and Pfizer vaccines could be due to the heterogeneous nature of this cohort, including both those who are older and those with other illnesses. Anti-S-RBD IgG and nAb IH% levels increased 5.94- and 1.26-fold on day 15, 3.63- and 1.22-fold on day 60, and 2.33- and 1.26-fold on day 90 after the third BNT162b2 vaccine dosage compared to pre-vaccination values (Day 0). Experts are still learning about COVID-19. Experts agree people with compromised immune systems should still get vaccinated, Goodman said, but they also should continue to wear face masks, practice social distancing and "remain pretty. No reuse allowed without permission. Primer specificity stringency. The decrease in anti-S-RBD IgG titers on days 60 and 90 were statistically significant in both groups (. Impact of SARS-CoV-2 variants on the total CD4+ and CD8+ T cell reactivity in infected or vaccinated individuals. Redjoul, R.; Le Bouter, A.; Parinet, V.; Fourati, S.; Maury, S. Antibody response after third BNT162b2 dose in recipients of allogeneic HSCT. ; Giglio, R.; Vidali, M.; Scazzone, C.; Bivona, G.; Gambino, C.; Ciaccio, A.; Agnello, L.; Ciaccio, M. Evaluation of Anti-SARS-Cov-2 S-RBD IgG Antibodies after COVID-19 mRNA BNT162b2 Vaccine. The incidence and severity of breakthrough infection in vaccinated patients treated with RTX is also largely unknown. I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable. Antibody titers testing at 3-6 weeks, 3, 6 and 12 months after the complete 2-dose vaccination was available in 506 (89%), 429 (75% . This is by design: Like many of the microbes they mimic, the contents of the shots stick around only as long as it takes the body to eliminate . The monoclonal antibody combination tixagevimab/cilgavimab consists of 2 Fc-modified fully human monoclonal antibodies administered by intramuscular injection. It takes one to three weeks after an infection for antibodies to be detectable. The optimal antibody level required to protect patients from severe clinical outcomes according to the type of variant, as well as the involvement of T cell response in vaccination efficacy, have . This interval was then extended to 8-12 weeks, to allow as many people as possible to receive at least one dose and the associated degree of immunity. A positive antibody test result can help identify someone who has had COVID-19 in the past or has been vaccinated against COVID-19. Three main factors have been identified. sharing sensitive information, make sure youre on a federal And some evidence shows that as antibody levels decline, they are gradually replaced by higher-quality antibodies, suggesting that eventually, it takes fewer antibodies to stay protected. You are accessing a machine-readable page. As expected, antibodies waned over time, but memory B and T cells persisted for at least six months, which might suggest steady and durable protection from severe disease and hospitalization as a result of the virus, according to the Penn Medicine study published in Science. The findings suggest that declining antibody levels in the months after vaccination primarily represent a shift to a sustainable immune response. Indeed, six months after vaccination, the antibodies were noticeably better than they had been in the beginning. "In this study, we define the role of antibodies versus T cells in protection . ; Ciaccio, A.M.; Vidali, M.; Ciaccio, M. Longitudinal analysis of anti-SARS-CoV-2 S-RBD IgG antibodies before and after the third dose of the BNT162b2 vaccine. There is one pre-print study that offers some clues. People with count below 10 can also avoid the disease through cell immunity which is not measured by . In groups without and with past SARS-CoV-2 infection, nAb IH% levels rose 1.28- and 1.23-fold on day 15, 1.18- and 1.18-fold on day 60, and 1.11- and 1.11-fold on day 90, compared to pre-vaccination (day 0). Approval number: 2023-KY-001. Moreover, whether the prototype SARS-CoV-2 booster vaccination could help induce the antibody against Omicron variants? COVID-19; antibody reaction; immune-mediated neuromuscular disease; immunosuppressive therapy; vaccination. However, the immune response to doses separated by 4-12 weeks remains an area relatively unknown, especially for the Pfizer vaccine. ; Saltoglu, N.; Can, G.; Balkan, I.I. Antibody testing is primarily used to determine if a person has previously been infected with the COVID-19 virus. Eliakim-Raz, N.; Leibovici-Weisman, Y.; Stemmer, A.; Ness, A.; Awwad, M.; Ghantous, N.; Stemmer, S.M.
