The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccines have been associated with an up-regulated T helper type 1-cell response, possibly favoring an immune system imbalance. The first proof of principle for an EBV vaccine was reported by Epstein and colleagues (1985). EBNA-2 and EBNA-LP are also targets of CD4 T cells (reviewed in Taylor et al. Mice vaccinated with recombinant gp350 adjuvanted with a TLR4 agonist (glucopyranosyl lipid A) in emulsion developed EBV neutralizing antibodies and gp350-specific CD4 T cell responses (Heeke et al. Infection with EBV induces antibodies and T cells specific for viral proteins. In addition, priorities for future research that were identified included determining disease-predictive surrogate markers of EBV malignancies to use as endpoints for EBV vaccine trials, identifying immune correlates of protection from EBV infection and disease, establishing epidemiologic studies to determine the benefit of an EBV vaccine, development of a plan to determine vaccine efficacy for preventing malignancies, and establishing a strategy to facilitate collaborations between academic, industry, and government organizations to accelerate EBV vaccine development. A vaccine is currently unavailable. Characteristics of Hodgkins lymphoma after infectious mononucleosis. Recombinant gp350 vaccine for infectious mononucleosis: a phase 2, randomized, double-blind, placebo-controlled trial to evaluate the safety, immunogenicity, and efficacy of an Epstein . Cytotoxic CD4+ T cell responses to EBV contrast with CD8 responses in breadth of lytic cycle antigen choice and in lytic cycle recognition. Treatment Coping Infectious mononucleosis, often known simply as mono, is a viral infection caused by the Epstein-Barr virus (EBV). 2013). It is wise to avoid vigorous contact sports while you are infected with mono. Mouse immunized with these EBV VLPs produced neutralizing antibody and T cell responses to viral proteins (Ruiss et al. ELISA antibody titers to gp350 were induced in all the subjects in this study; neutralizing titers developed in 5060% of persons, and more persons receiving the vaccine in alum adjuvant developed neutralizing titers than those receiving vaccine in alum/MPL or no adjuvant. Accessed Nov. 22, 2022. Mono is a contagious illness that is usually caused by the Epstein-Barr virus. Ragot T, Finerty S, Watkins PE, Perricaudet M, Morgan AJ (1993). Adv Exp Med Biol. The level of virus in the blood has shown to be a risk factor for development of lymphoproliferative disease after hematopoietic cell transplantation (van Esser et al. Vaccination of common marmosets with vaccinia or adenovirus expressing gp350 reduced EBV replication after challenge with the virus (reviewed in Cohen 2015). Infectious mononucleosis (IM) is a common disease encountered by otolaryngologists, caused by the initial infection with various types of viruses. Immunodominance of lytic cycle antigens in Epstein-Barr virus-specific CD4+ T cell preparations for therapy. A potential concern is that patients with who have X-linked lymphoproliferative disease type 1 might not have a normal response to the EBV vaccine. B cells neutralizing antibody reaches peak levels at a median of about 180 days after the onset of infectious mononucleosis (Bu et al 2015). Elliott SL, Suhrbier A, Miles JJ, Lawrence G, Pye SJ, Le TT, Rosenstengel A, Nguyen T, Allworth A, Burrows SR, Cox J, Pye D, Moss DJ, Bharadwaj M (2008). Epstein-Barr virus infection. The reasons are not entirely clear, but likely include: skepticism about what an EBV vaccine could actually achieve; the impression that infectious mononucleosis is a trivial disease; the lack of . While most cases of mono resolve after a few weeks, in very rare cases, the virus can remain active within the body indefinitely. The highest levels of antibodies to gp350 were observed in animals vaccinated with soluble gp350. These B cells circulate throughout the body and may undergo lytic infection with production of progeny virus or, more often, undergo latent infection with very limited viral gene expression. It's spread through saliva. While initial studies showed that CD4 T cell responses that lyse virus-infected B cells are directed against structural proteins including EBV gp350 and glycoprotein B (Adhikary et al. Another approach to an EBV vaccine used EBV VLPs. Rational Design of an Epstein-Barr Virus Vaccine Targeting the Receptor-Binding Site. 2015); over time the number of CD8 T cells recognizing lytic antigens declines and T cells recognizing EBV latency proteins increase (Hislop et al. Can You Have Chronic Mono? Third, a portion of the ectodomain of gp350 (containing the CR2 binding domain of gp350) was fused to ferritin or encapsulin and nanoparticles were produced that contain 24 or 60 copies of gp350, respectively (Kanekiyo et al. 2015). Therefore, a vaccine that induced an effective T cell response to EBV might reduce symptomatic disease and/or lower the viral load. There is no vaccine to protect you against mono, and people can spread it before they know they have the illness. 1999). al 2009). EBV gp350 has been shown to induce EBV neutralizing antibodies, ADCC, or T cell responses in animals using a number of different platforms. Please enable it to take advantage of the complete set of features! How Long Do They Last? Ginsburg CM, Henle G, Henle W. An outbreak of infectious mononucleosis among the personnel of an outpatient clinic. infectious mononucleosis an acute infectious disease that causes changes in the leukocytes; it is . There is a problem with EBV can stay in your saliva for months after you're infected, so even if you don't have symptoms or feel sick, you may be able . Accessibility Thus, antibody maturation can take over a year to occur after primary EBV infection. Your healthcare provider will assess your symptoms and check for an enlarged spleen or liver. Since EBV seronegative recipients of solid organ transplants typically become infected from EBV in the transplanted organ, a vaccine to control proliferation of virus-infected cells in the organ may require T cells in addition to antibody. A prospective study of military personnel showed that the risk of multiple sclerosis increased as serum titers to the anti-EBV nuclear antigen complex increased; the risk was 36-fold higher in persons with titers 320 compared to those with titers <20 (Munger et al. Long HM, Leese AM, Chagoury OL, Connerty SR, Quarcoopome J, Quin LL, Shannon-Lowe C, Rickinson AB (2011). An official website of the United States government. A virus-free immunogen effective against Epstein-Barr virus. Swollen spleen (an organ in the upper-left side of the abdomen). The evolution of Epstein-Barr virus inferred from the conservation and mutation of the virus glycoprotein gp350/220 gene. The prevalence of multiple sclerosis in the United States is about 1 to 1.5 per 1000. Also, EBV reactivation has been postulated after COVID-19 vaccination, but only in the immunosuppressed. The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, has launched an early-stage clinical trial to evaluate an investigational preventative vaccine for Epstein-Barr virus (EBV). 1993; Kawaguchi et. Mice with mutations in SH2D1A have acute IgG antibody responses, but a near complete absence of antigen-specific long-lived plasma cells and memory B cells (Crotty et al. First, the Epstein-Barr virus has been shown to present an even greater threat. On average, the prodrome phase lasts three . health information, we will treat all of that information as protected health The promise of a prophylactic Epstein-Barr virus vaccine eCollection 2022. J Infect Dis. Early events in Epstein-Barr virus infection of human B lymphocytes. 2006). The disease can cause symptoms such as: There's no clear-cut treatment for mono. Handel AE, Williamson AJ, Disanto G, Handunnetthi L, Giovannoni G, Ramagopalan SV (2010). Mutations in STXBP2, PRF1, or UNC13D predispose to severe EBV infections and hemophagocytic lymphohistiocytois. gH/gL and gB are essential for herpesvirus infection of cells and gp42 is required for EBV entry into B cells. Anti-Epstein-Barr virus antibodies as serological markers of multiple sclerosis: a prospective study among United States military personnel. Recombinant gp350 vaccine for infectious mononucleosis: a phase 2, randomized, double-blind, placebo-controlled trial to evaluate the safety, immunogenicity, and efficacy of an Epstein-Barr virus vaccine in healthy young adults. Another approach for a prophylactic EBV vaccine is to induce T cell responses to EBV latency proteins, such those initially expressed during EBV infection of B cells. 2013).

Mono is spread through a variety of means. Immediate early and early lytic cycle proteins are frequent targets of the Epstein-Barr virus induced cytotoxic T cell response. Mono is a moderately contagious condition usually caused by the Epstein-Barr virus (EBV). information and will only use or disclose that information as set forth in our notice of Recombinant gp350 vaccine for infectious mononucleosis: a - PubMed But most people with the disease get better within a month. This suggests that a vaccine that induces persistently elevated levels of EBV B neutralizing antibodies might reduce the rate of nasopharyngeal carcinoma. Hislop AD, Annels NE, Gudgeon NH, Leese AM, Rickinson AB (2002). Morgan AJ, Mackett M, Finerty S, Arrand JR, Scullion FT, Epstein MA (1988). The vaccine had demonstrable efficacy (mean efficacy rate, 78.0% [95% confidence interval {CI}, 1.0%-96.0%]) in preventing the development of infectious mononucleosis induced by EBV infection, but it had no efficacy in preventing asymptomatic EBV infection. 1976;104(5):571-575. doi:10.1093/oxfordjournals.aje.a112332. Li W, Duan X, Chen X, Zhan M, Peng H, Meng Y, Li X, Li XY, Pang G, Dou X.

In another approach, two Newcastle disease virus VLPs were constructed; one containing the ectodomain of EBV gH fused to the Newcastle disease virus F protein, the EBV gL ectodomain fused to the Newcastle disease virus HN protein, and the carboxyl half of EBV EBNA1 fused to the Newcastle disease virus NP protein (Perez et al. Recent sequencing of clinical isolates indicates that gp350 is less conserved than other glycoproteins important for infection (Palser et al. Finally, mutations in other genes including ATM, CARD11, CTPS1, FCGR3A, GATA2, MCM4, PIK3CD, PIK3R1, and STK4, as well as genes associated with severe combined immunodeficiency, increase the risk of severe EBV disease as well as infections due to other pathogens.

Rhesus macaques were vaccinated with rhesus LCV gp350, virus-like replicon particles expressing rhesus LCV gp350, a mixture of replicon particles expressing rhesus LCV gp350, EBNA-3A, and EBNA-3B, or saline. No serious adverse events were reported. 2000). Sore throat. 1986). It spreads primarily through saliva. Immunization of HLA-A2 transgenic mice with gH peptides induced cytotoxic T cell responses and protected the animals again vaccinia virus expressing gH (Khanna et al. EBV has also been associated with multiple sclerosis. 2011)a, there was a strong consensus that clinical trials be performed with vaccine candidates with a goal to prevent infectious mononucleosis and EBV-associated cancers. How long is mono contagious? Taylor GS, Long HM, Brooks JM, Rickinson AB, Hislop AD (2015). 2007). Epstein-Barr virus (EBV) is the primary cause of infectious mononucleosis and is associated with several malignancies, including nasopharyngeal carcinoma, gastric carcinoma, Hodgkin lymphoma, Burkitt lymphoma, and lymphomas in immunocompromised persons, as well as multiple sclerosis. The amino acid sequence of gp350 is highly conserved among different isolates especially in the amino terminal region; however, there are differences in the amino terminal region between EBV types 1 and 2 (Lees et al. These results emphasize the important role of immune responses to gp350 for protecting animals from infection and for reducing the level of EBV in the blood in animals that still become infected after challenge. To provide you with the most relevant and helpful information, and understand which and transmitted securely. Adenovirus Prevention & Treatment There is no vaccine to protect against infectious mononucleosis. "Recombinant gp350 vaccine for infectious mononucleosis: a phase 2, randomized, double-blind, placebo-controlled trial to evaluate the safety, immunogenicity, and efficacy of an Epstein-Barr virus vaccine in healthy young adults". no vaccine exists that will prevent EBV infection. Expression of Epstein-Barr virus gp350 as a single chain glycoprotein for an EBV subunit vaccine. Mayo Clinic; 2022. While the numbers were small, the results resembled the phase 2 gp350 trial with a possible reduction in infectious mononucleosis with the vaccine without a reduction in asymptomatic EBV infection. Read our, Ebola Virus Risk: A Global Look at the Effects. Infectious mononucleosis is characterized by swollen lymph glands, fever, sore throat, and extreme fatigue. The virus spreads from person to person mainly through saliva. official website and that any information you provide is encrypted sharing sensitive information, make sure youre on a federal When you visit the site, Dotdash Meredith and its partners may store or retrieve information on your browser, mostly in the form of cookies. Glycoproteins, present on the surface of viruses and virus-infected cells, have typically been primary candidates for development of vaccines to prevent infection and/or disease. the unsubscribe link in the e-mail. A chimeric EBV gp350/220-based VLP replicates the virion B-cell attachment mechanism and elicits long-lasting neutralizing antibodies in mice. The former is important since infectious mononucleosis can be associated with debilitating fatigue as well as other complications, and EBV infectious mononucleosis is associated with increased rates of Hodgkin lymphoma and multiple sclerosis. Immunization of mice with the nanoparticles induced neutralizing titers that were about 1,000-fold higher than that obtained with soluble gp350; immunization of LCV-seropositive cynomolgus monkeys with the nanoparticles induced 3- to 10-fold higher neutralizing titers than that obtained with soluble gp350. How to Get Rid of Mono Fast: Treatments, Home Remedies, and More 2001; Aalto et al. Sore throat, enlarged lymph nodes, and extreme fatigue are common symptoms. 2001). Similarly, antibody-dependent cell-mediated phagocytosis (ADCP) was rarely detected during the initial phase of infectious mononucleosis, but was frequently present 6 months later (Weiss et al. Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. About Epstein-Barr virus (EBV). Antibody-dependent cellular cytotoxicity (ADCC) directed against cells expressing gp350 was not detected in sera from persons at the onset of infectious mononucleosis, but was detected in healthy EBV-seropositive persons (Xu et al. The symptoms of infectious mononucleosis are thought to be due to the T cell response to the virus (Silins et al. Subsequent experiments performed in cottontop tamarins showed that purified gp350 in immunostimulating complexes (ISCOMs) or muramyl dipeptide in squalene, recombinant gp350 in alum or muramyl dipeptide in squalene, or adenovirus or vaccinia virus expressing gp350 protected animals from lymphoma after challenge with EBV (reviewed in Cohen 2015). Prednisone withdrawal: Why taper down slowly? Antibiotics will not treat viral infections such as mono. Ruiss R, Jochum S, Wanner G, Reisbach G, Hammerschmidt W, Zeidler R (2011). 88 of 90 persons in the vaccine group and 90 of 91 in the placebo completed the study. Click here for an email preview. Mononucleosis Facts and Statistics: What You Need to Know. Precopio ML, Sullivan JL, Willard C, Somasundaran M, Luzuriaga K (2003). 2010). What Are the Stages of Mono? In another study, not all cottontop tamarins that developed high neutralizing titers to EBV after vaccine were protected against challenge with the virus (Epstein et al. It's often spread through contact with infected saliva from the mouth. Hjalgrim H, Askling J, Rostgaard K, Hamilton-Dutoit S, Frisch M, Zhang JS, Madsen M, Rosdahl N, Konradsen HB, Storm HH, Melbye M (2003). By 12 hours after infection EBV nuclear antigen 2 (EBNA-2) and EBNA leader protein (EBNA-LP) are detected (Alfieri et al. If you do become sick with mono, you will be able to recover with plenty of rest and fluids. 1999). About 75% of young adults who have an EBV infection will get mono. One month after receipt of the final dose of gp350 vaccine, 98.7% of subjects showed seroconversion to anti-gp350 antibodies (95% CI, 85.5%-97.9%), and they remained anti-gp350 antibody positive for >18 months. Don't kiss or share utensils or . Glycoprotein gp350 is the principal target of neutralizing antibody for EBV infection of B cells (North et al. Since EBV is transmitted through close contact with others, the best way to prevent infection is by doing the following: Boosting your immune system by eating a healthy diet and getting regular exercise and enough sleep is a good way to prevent not just mono, but any infection. 2015). . 2018;1045:477-493. doi: 10.1007/978-981-10-7230-7_22. EBV-positive post-transplant lymphoproliferative disease usually occurs within one year of hematopoietic stem cell transplantation and within three years after solid organ transplantation. The virus infects epithelial cells in the oropharynx where it replicates and subsequently infects B lymphocytes, or it may infect B cells in the tonsillar crypts directly.
