Posts about mRNA vaccine written by Dr. Francis Collins. The Moderna and Pfizer/BioNTech vaccines are forms of mRNA vaccine. SARS-CoV-2 mRNA vaccine development enabled by prototype pathogen preparedness / Kizzmekia Corbett. Participants who had received both doses of SARS-CoV-2 mRNA vaccine before March 13, 2021, were followed through April 13, 2021, and assessed for their serologic response. METHODS We investigated early serological response after COVID 19 vaccination with Pfizer/BioNTech (BNT162b2) mRNA vaccine in 78 patients undergoing hemodialysis, 74 kidney transplant recipients, and 7 healthy controls. We read with interest the work by Geisen and colleagues1 on the efficacy and safety of anti-SARS-CoV-2 mRNA vaccine in patients with rheumatic diseases. Scientists and collaborators had already created stabilized coronavirus spike proteins (which the viruses use to enter cells and mRNA vaccines use to create antibody responses) before SARS … In late 2003 and early 2004, new infections in persons who had contact with animals infected with SARS-CoV strains significantly different from those predominating in the 2002–2003 outbreak were reported in Guangdong, China . Vaccines charge up natural immunity against SARS-CoV-2. Nucleoside-modified viral messenger RNA (v mRNA) genomic sequence is encapsulated within nanoparticles—specifically lipid ones (LNPs). This vaccine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. The current research has also confirmed that after the second dose of mRNA vaccine, anti-RBD IgG levels were higher than those recovered from COVID-19 infection. Among 3,950 participants with no previous laboratory documentation of SARS-CoV-2 infection, 2,479 (62.8%) received both recommended mRNA doses and 477 (12.1%) received only one dose of mRNA vaccine. As an mRNA that encodes only the antigenic proteins, the vaccine will feature a very high level of safety considering that it does not include viral retrotranscriptase. Either mRNA-LNPs or locally produced antigen are taken up by antigen-presenting cells (APCs) (2), such as dendritic cells (DCs). The above data suggest that development of a SARS-CoV-2 vaccine will require careful design and testing to assure efficacy and safety. There are no specific guidelines for use of messenger RNA (mRNA) vaccines or contraindications to mRNA vaccines. Then the ferrets were exposed intranasally to the SARS virus, which infected more than 8,000 people and killed 774 between November 2002 and July 2003. mRNA vaccines elicit a potent immune response in CD8+T cells, responsible for detecting viral infection. The SARS-CoV-2 mRNA vaccines, if approved, would be the first to gain approval for use for vaccination of humans. The only evidence on safety of mRNA vaccines comes from small phase I and phase II trials of SARS-CoV-2 vaccines, with follow-up typically less than two months. The Advantages of Synthetic mRNA Vaccines In the context of emerging infectious disease, mRNA vaccines convey several promising characteristics. By last October, about three out of every four residents of Manaus, Brazil already had been infected with SARS-CoV-2, the virus that causes COVID-19 [1]. Summary. This gave laboratory scientists the ability to compare what they were seeing in patient samples to the vaccine. Among Covid-19 vaccine technologies, mRNA represents faster, easier approach, some experts say There are multiple platforms for developing vaccines against the SARS … mRNA Vaccine against SARS-CoV-2 induces robust Ab responses She ended her talk highlighting that all these achievements were made possible via extensive collaborative projects with other research groups based at the University of Texas at Austin, The Scripps Research Institute, University of Washington, the University of North Carolina at Chapel Hill and many more. Your COVID-19 questions answered . Know the risks and potential benefits of clinical … The "CVnCoV" vaccine is injected into the muscle. The concept behind these vaccines is similar to the mRNA vaccines in the sense that they deliver the instructions for our cells to produce the spike protein of SARS-CoV-2. There has not been a similar reporting pattern observed after receipt of the Janssen COVID-19 Vaccine (Johnson & Johnson). When it became clear in early 2020 that the Sars-CoV-2 virus posed a pandemic threat, researchers who’d been exploring an innovative way to make vaccines saw an … With the SARS-CoV-1 in 2003, it was clear who was infected so they could be isolated. This date marked the beginning of human clinical trials to test the safety of a new COVID-19 vaccine from the biotechnology company Moderna. SARS-CoV-2 mRNA Vaccine. Both products utilize mRNA platforms encoding the viral spike glycoprotein of SARS-CoV-2. Posts about mRNA vaccine written by Dr. Francis Collins. Continue Reading. Doria-Rose N, Suthar MS, Makowski M, et al. Antibody Persistence through 6 Months after the Second Dose of mRNA-1273 Vaccine … By last October, about three out of every four residents of Manaus, Brazil already had been infected with SARS-CoV-2, the virus that causes COVID-19 [1]. Severe acute respiratory syndrome (SARS) is a viral illness that affects the respiratory (breathing) system. We're answering your questions about the pandemic. Two vaccine candidates show promise in knocking out the pandemic. Nevertheless, exact design of the actual vaccine … Anderson EJ, Rouphael NG, Widge AT, et al. Two preprints, unpublished non-peer reviewed studies, look at giving a single dose of COVID-19 mRNA vaccine to those who have previously been infected with SARS … Posted on April 27th, 2021 by Dr. Francis Collins. Vaccine manufacturer for the SARS-CoV-2 novel coronavirus, Pfizer, says it will advance its mRNA vaccine business beyond the virus which causes the disease the Chinese Communist Party-friendly World Health Organization dubbed Coronavirus Disease 2019 (COVID-19). In order to produce vaccines against COVID-19, Moderna and Pfizer/BioNTech first needed to identify the right mRNA sequences for proteins that would make suitable vaccine components. Without the vaccine, your body has to identify the virus, learn how to fight it and carry out an immune response. mRNA vaccines elicit a potent immune response in CD8+T cells, responsible for detecting viral infection. What. On day 58, … Additionally, mRNA vaccines represent a new vaccine technology leading to increased insecurity especially in patients with CID. COVID-19 virus is similar to the SARS virus of 2003, and previous research of the SARS outbreak suggested potential vaccine components. Prior SARS-CoV-2 infection boosts protection after first vaccine dose. One surprising star of the coronavirus pandemic response has been the molecule called mRNA. The claims that these mRNA vaccines will cause the immune system to attack syncytin-1 are unfounded. The mRNA-1273 vaccine induced anti–SARS-CoV-2 immune responses in all participants, and no trial-limiting safety concerns were identified. While substantial data on the efficacy and safety of SARS-CoV-2 vaccination have been created during the last months, it is currently unclear whether the vaccination is efficacious and safe in patients with autoinflammatory diseases (AIDs). mRNA emerged as an alternative to traditional vaccine development in the early 1990s, building on research involving RNA injections into mice at the Waisman Center at the University of Wisconsin-Madison. by Rockefeller University. mRNA vaccines … Safety and Immunogenicity of SARS-CoV-2 mRNA-1273 Vaccine in Older Adults. A study has found that a single dose of vaccine boosts protection against SARS-CoV-2 coronavirus variants, but only in those with previous Covid-19. SARS-CoV-2 vaccines while triggering disease activity in previously stable lupus. The emergence of SARS-CoV in 2003 and SARS-CoV-2 in 2019 highlights the need to develop universal vaccination strategies against the broader Sarbecovirus subgenus. The COVID-19 mRNA vaccines authorized for use were found to be safe and effective in clinical trials and real-world conditions. Acknowledgments and Permission The mRNA Vaccine Slide Set is a collaborative effort between the University of Washington Infectious Diseases Education and Assessment (IDEA) Program and Cognition Studio, Inc. •Project Design and Content Development qDavid Spach, MD (University of Washington) and Cognition Studio, Inc. •Content Development and Medical Illustrations ... including SARS-CoV-2, … As previously shown for mRNA vaccines against SARS-CoV-2 13,37, CVnCoV was able to induce both S-specific CD4 + and CD8 + T-cell responses in mice that were comparatively high at low vaccine doses 37. mRNA vaccines work by introducing a piece of mRNA into the body that corresponds to a viral protein. SARS-CoV-2 (COVID-19) vaccine is used to prevent coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Nano Letters 20, 4543-4549. Nine patients received two doses of the mRNA-1273 vaccine (Moderna), all others received two doses of the BNT162b2 vaccine (Pfizer–BioNTech). (Funded by the National Institute of Allergy and Infectious Diseases and others; mRNA-1273 ClinicalTr … The mRNA sequence for the Pfizer/BioNTech vaccine was made available to the public in December by the World Health Organization, with the company confirming its accuracy.

Instead, one question to ask might be whether Pfizer and Moderna’s mRNA vaccines, which had an especially robust response (as much as 95% efficacy in clinical trials), also have potential to … How mRNA vaccines work Every virus is different. Since April 2021, increased cases of myocarditis and pericarditis have been reported in the United States after mRNA COVID-19 vaccination (Pfizer-BioNTech and Moderna), particularly in adolescents and young adults. mRNA based SARS-CoV-2 vaccine candidate CVnCoV induces high levels of virus neutralizing antibodies and mediates protection in rodents Susanne Rauch, Nicole Roth, Kim Schwendt, Mariola Fotin-Mleczek, Stefan O. Mueller, Benjamin Petsch Abstract The devastating SARS-CoV-2 pandemic demands rapid vaccine development and large scale production to meet worldwide needs. Half the participants in the study, dubbed CoVPN 3008, would receive the current Moderna vaccine, which contains mRNA that codes for the surface protein, spike, of SARS-CoV-2. Additionally, the mRNA vaccines carry a “recipe” for producing only one protein, the SARS-CoV-2 spike protein, and both doses of the vaccine carry the same recipe. As detailed in a recently published study in Immunity (DOI: 10.1016/j.immuni.2020.11.009), two SARS-CoV-2 mRNA vaccines—but not a recombinant protein vaccine formulated with the MF59-like adjuvant AddaVax—promote robust GC-derived immune responses in mice, she says. The mRNA-1273 COVID-19 vaccine from Moderna shows promise as it has been proven overall safe in phase 1 clinical trials, as well as immunogenic. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) messenger RNA (mRNA)-based vaccines are ~95% effective in preventing coronavirus disease 20191–5. The Advantages of Synthetic mRNA Vaccines In the context of emerging infectious disease, mRNA vaccines convey several promising characteristics. Previous studies reported that mRNA vaccine indicated efficacy for preventing COVID-19 illness, which was helpful for controlling the COVID-19 pandemic 1,2. Plasma ELISAs and neutralizing activity. Prior to COVID‑19, a vaccine for an infectious disease had never been produced in less than several years – and no vaccine existed for preventing a coronavirus infection in humans. Corbett, K. S., et al. The SARS-CoV-2 mRNA vaccines, if approved, would be the first to gain approval for use for vaccination of humans. In all there were just over 8,000 cases of SARS-CoV-1, … (mRNA-1273) or Pfizer/BioNTech (BNT162b2) vaccines trials; the risk of vaccine-associated enhanced respiratory disease was observed in animal models of SARS-CoV and Middle East respiratory syndrome coronavirus infections, and it was associated with vaccine antigens that induce antibodies with poor neutralising activity and Th2-biased If the … “The fact that we’ve had two coronavirus epidemics in the last two decades tells us this is something that can keep happening,” Martinez says. Learning about … Getty/Skaman306. But we also don’t know the same about the novel coronavirus — SARS-CoV-2 … (2020) Deconvoluting lipid nanoparticle structure for messenger RNA delivery. The host cells receive the instruction from the mRNA to produce protein of the S-antigen unique to SARS-CoV-2, allowing the body to generate an immune response and to retain that information in memory immune cells. N Engl J Med 2020; 383:1920. If the amino acid sequence of the mRNA changes, its antigenicity will also change accordingly. Novavax, a protein-based vaccine, uses a laboratory-made version of the Sars-CoV-2 spike protein to stimulate an immune response. Posted on April 27th, 2021 by Dr. Francis Collins. The investigational vaccine known as mRNA-1273 protected mice from infection with SARS-CoV-2, the virus that causes COVID-19, according to research published today in Nature.Scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and the biotechnology company Moderna, based in Cambridge, Massachusetts, … Coronavirus mRNA vaccines won't just end the pandemic. Antibody Persistence through 6 Months after the Second Dose of mRNA-1273 Vaccine … mRNA vaccines have been studied before for flu, Zika, rabies, and cytomegalovirus (CMV). Now, researchers will be able to check for markers of the Moderna vaccine as well. How mRNA vaccines from Pfizer and Moderna work, why they’re a breakthrough and why they need to be kept so cold November 18, 2020 8.19am EST. The findings have important implications for the roll-out of the global vaccine … To investigate how human antibody responses to vaccines are influenced by viral mutations, we used deep mutational scanning to compare the specificity of polyclonal antibodies elicited by either two doses of the mRNA-1273 COVID-19 vaccine or natural infection with SARS-CoV-2. In this case, an adenovirus (which normally causes a mild or asymptomatic common cold and completely lacks the enzymes require to alter our DNA, making them an excellent DNA delivery vehicle for vaccines) that … Jun 16, 2021. Serum samples were collected at baseline, 3 weeks after the first vaccination, and 2 weeks after the second vaccination. Quantitative antibody testing was done using the Roche Elecsys Anti-SARS-CoV-2 spike subunit 1 (S1) assay that measures … on day 0 and 28 and sacrificed for serum antibody measurements or challenged with live virus on day 56. The race for a vaccine against the novel coronavirus, or SARS-CoV-2, is on, with 54 different vaccines under development, two of which are already being tested in humans, according to the World Health Organization. a-b, Plasma IgG antibody binding to SARS … Author. Two COVID-19 vaccines, produced by Pfizer-BioNTech and Moderna, have been granted Emergency Use Approval (EUA) by the FDA. Any insight could help to guide the future design of mRNA vaccines against COVID-19 or other diseases. But mRNA … With a new threat at hand, scientists at the NIH swiftly developed a vaccine candidate against the novel coronavirus that causes COVID-19. A new study suggests that there is a strong boost to the immunity of everyone who receives the first dose of an mRNA vaccine, including those who have previously had a SARS … Researchers at La Jolla Institute for Immunology (LJI) have found that T cells from people who have recovered from COVID-19 or received the Moderna or Pfizer-BioNTech vaccines are still able to recognize several concerning SARS-CoV-2 variants. To prevent a future coronavirus pandemic, UNC-Chapel Hill researchers designed the vaccine to provide protection from the current SARS-CoV-2 coronavirus and a group of coronaviruses known to make the jump from animals … No vaccine for SARS, so why do we need one now? The strict quarantine measures paid off, and by July 2003, the WHO declared the threat over. Around half of people over 80 years of age require a second dose of the Pfizer-BioNTech SARS-CoV-2 mRNA-based vaccine in order to achieve maximum virus neutralization, a Nature study involving 140 participants suggests. Vaccines by Pfizer and Moderna carry mRNA instructions to produce the spike protein SARS-CoV-2 uses to infect human cells. The mRNA vaccines are intended to induce an immune response to spike proteins of SARS-CoV-2, but these spike proteins (transcribed for replication within cellular ribosomes) also contain a homologous form of syncytin-1. And among the different candidates is a new player on the scene – mRNA vaccines. These APCs then traffic to the lymph nodes (3) where they are able to prime CD4 and CD8 T lymphocytes (4). A primer on the history, scope, and safety of mRNA vaccines and therapeutics. Eygeris, Y., et al. ( A to D ) The serum dilution resulting in 50% neutralization (ID 50 ) of Wuhan-Hu-1 (A), B.1.351 (B), B.1.351–Δ242-243 (C), and SARS-CoV-1 (D) pseudoviruses was measured in PIDs before and after one or two immunizations with the Pfizer-BioNTech or Moderna vaccines and … However, vaccines have been produced against several animal diseases caused by coronaviruses, including (as of 2003) infectious bronchitis virus in birds, canine coronavirus, and feline coronavirus. An mRNA Vaccine against SARS-CoV-2 - Preliminary Report. Most concerning is the vaccine’s potential to cause female infertility. These events indicate that a SARS epidemic may recur at any time in the future, either by the virus escaping from laboratory samples or by SARS-CoV isolates … Tell your doctor right away if you have a rash, itching, a fast heartbeat, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after receiving the vaccine. The CDC said it would never happen. Vaccines by Pfizer and Moderna carry mRNA instructions to produce the spike protein SARS-CoV-2 uses to infect human cells. However, vaccines have been produced against several animal diseases caused by coronaviruses, including (as of 2003) infectious bronchitis virus in birds, canine coronavirus, and feline coronavirus. While the mRNA COVID-19 vaccines represent a new approach to making vaccines, they function like all other vaccines that train people’s immune systems to recognize and react to future pathogens. The Moderna COVID-19 vaccine is a messenger RNA (mRNA) based vaccine against coronavirus disease 2019 (COVID-19). No one knows for sure whether one vaccine will last longer than another. Most vaccines for SARS-CoV-2 provoke an immune response that targets the coronavirus spike protein, which is found on the surface of the virus and gives the virus its characteristic spiky shape. At a median of 29 days after dose 2, antibodies were detected among 54% (95% CI, 50 … On the plus side, immunization with rMVA-S induced a rapid immune response following exposure to the virus, the researchers wrote. These findings support further development of this vaccine. Early in the development of mRNA vaccine technology, fetal cells were used for “proof of concept” (to demonstrate how a cell could take up mRNA and produce the SARS-CoV-2 spike protein) or to characterize the SARS-CoV-2 spike protein. We read with interest the work by Geisen and colleagues1 on the efficacy and safety of anti-SARS-CoV-2 mRNA vaccine in patients with rheumatic diseases. While a two-dose immunization regimen with the BNT162b2 vaccine has been demonstrated to provide a 95% efficacy in naïve … These results raise safety concerns for S protein-based SARS-CoV and MERS-CoV vaccines. In science, as in life, it's wise never to say never: an MIT lab suspects that the genetic material from the mRNA vaccines can work its way into DNA. Effective vaccines against these infections have eluded scientists for various reasons. This Phase 1 dose-ranging study will assess the safety and immunogenicity of mRNA-1283, a next-generation vaccine candidate against COVID-19. About PDB-101. ROLLING MEADOWS, Ill., DECEMBER 29, 2020 – The American Society for Dermatologic Surgery (ASDS) crafted, “Guidance Regarding SARS-CoV-2 mRNA Vaccine Side Effects in Dermal Filler Patients.”This guidance shares data from the U.S. Food and Drug Administration (FDA) … expert reaction to two preprints looking at a single dose of mRNA vaccines in those who have previously been infected with SARS-CoV-2 . One potential strategy to overcome the ADE problem is to design vaccines … However, in order to produce vaccines against COVID-19, Moderna and Pfizer/BioNTech first needed to identify the right mRNA sequences for proteins that would make suitable vaccine components. Prior to COVID‑19, a vaccine for an infectious disease had never been produced in less than several years – and no vaccine existed for preventing a coronavirus infection in humans. In the Cell study, Qin and his colleagues developed a vaccine consisting of mRNA that encodes the receptor-binding domain (RBD) of the spike (S) protein, which is located on the surface of SARS … ... RNA, SARS, SARS … Early data suggest that the mRNA vaccines in development against SARS-CoV-2 are … The pre-clinical effort was driven in part by Dr. Kizzmekia Corbett. Plasma ELISAs and neutralizing activity. Study: The SARS-CoV-2 mRNA vaccine breakthrough infection phenotype includes significant symptoms, live virus shedding, and viral genetic diversity. Balb/c or C57BL/6 mice were vaccinated i.m. There are several vaccine types currently being pursued including mRNA, DNA, recombinant protein, virus-like particle, and live-attenuated or killed virus. Among Covid-19 vaccine technologies, mRNA represents faster, easier approach, some experts say There are multiple platforms for developing vaccines against the SARS … Share via: Print; Font Size A A A. Both these viruses closely resemble those that infect bats. a-b, Plasma IgG antibody binding to SARS … (2020) SARS-CoV-2 mRNA vaccine designs enable by prototype pathogen preparedness. Send yours to COVID@cbc… Five mRNA vaccines for Covid-19 are already in clinical trials, including Imperial’s, and there are at least another 20 in development. Only 1% of the infected people had a SARS-CoV-2 whose spike matched the mRNA used in the vaccine. N Engl J Med 2020; 383:2427. Spike protein mRNA are injected into the body. It is possible that these vaccines could elicit antibodies with distinct specificities compared to natural infection due to variation in the spike (such as the S-2P mutations) or divergent immune responses to a two-dose mRNA vaccine versus infection. In a nutshell, vaccines grant immunity by teaching the body how to react to the Sars-CoV-2 coronavirus. Specifically, the mRNA in these vaccines carries the instructions for how to make the SARS-CoV-2 spike protein, or a portion of it, depending on the vaccine. Although relatively easy and quick to produce compared to traditional vaccine-making, no mRNA vaccine or drug has ever won approval. The rapid development and deployment of mRNA-based vaccines against the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) led to the design of accelerated vaccination schedules that have been extremely effective in naïve individuals. mRNA is a molecule that essentially delivers instructions to cells to build specific proteins. Third, major advances in vaccine technologies over the last 5-10 years greatly accelerated the development of vaccines for SARS-CoV-2, the virus that causes COVID-19. Scientists are developing a new super vaccine of mRNA origin to fight against SARS-CoV-2 mutants The vaccine generated effective antibodies against the B.1.351 variant A Study to Evaluate Safety, Reactogenicity and Immunogenicity of the SARS-CoV-2 mRNA Vaccine CVnCoV in Adults With Co-morbidities for COVID-19. BioPharma. On day 58, challenged mice were sacrificed and lungs obtained for virus and histopathology. mRNA vaccines 91% effective after 2 doses In the first study, a team led by the Centers for Disease Control and Prevention COVID-19 Response Team tested 3,975 coronavirus-naïve healthcare workers, first responders, and other essential workers who received one or two doses of the Pfizer/BioNTech or Moderna mRNA vaccine or were unvaccinated from Dec 14, 2020, to Apr 10, 2021. Some currently available COVID-19 vaccines rely on messenger RNA or mRNA strands to teach the human immune system to recognise the SARS-CoV-2 … The events in (2)–(4) … Pfizer-BioNTech and Moderna have developed mRNA-based vaccines that demonstrate more than 90% efficacy against SARS-CoV-2 clinical disease in clinical trials. This high vaccine efficacy is associated with very few adverse events, although local and systemic reactogenicity to vaccine are common. Citation: A Series of Patients With Myocarditis Following SARS-CoV-2 Vaccination With mRNA-1279 and BNT162b2. In contrast to conventional vaccine platforms such as live attenuated or inactivated virus, mRNA vaccines are a promising alternative technology with characteristics that make them promising for SARS-CoV-2. After the injection, the body recognizes the protein as something that does not belong there. Like the Pfizer and Moderna vaccines… N Engl J Med 2020; 383:1920. In a March 23 article by the Wall Street Journal, Pfizer CEO Albert Bourla said his company gained years of […] No large trials of any mRNA vaccine have been completed yet. Board certified dermatologists provide information and perspective on the incidence of adverse reactions. by Rockefeller University. ##version 0.21Beta 04/14/21: (updates intended to (i) clarify the clinical and research importance of sequence information and strand topology measurements, and (ii) clarify that the mRNA sequence is not a recipe to produce vaccine)## The outer envelope of the vaccine is designed to deliver this RNA into cells, where it directs construction of many copies of the spike protein. As soon as the necessary information about the virus that causes COVID-19 was available, scientists began designing the mRNA instructions for cells to build the unique spike protein into an mRNA vaccine. The vaccine contains a molecule called mRNA which serves as an instruction manual for the cells in the body to produce a piece of protein from SARS-CoV-2 which activates the body´s defense system. A video which uses a research paper to argue that mRNA vaccines will make people fatally weakened to other diseases makes untrue claims about the study, according to the paper’s lead author. So nobody knows if mRNA vaccines would pose any harm in the long-run. The heart of the vaccine is a strand of RNA that encodes the spike surface glycoprotein of SARS-CoV-2. An adjuvant is a substance that may be added to a vaccine to improve the immune response so that less of the vaccine … Listing a study does not mean it has been evaluated by the U.S. Federal Government. The cell uses the mRNA from the vaccine as the blueprint to build the SARS-CoV-2 spike protein. The claims made in the … On 16 March 2020, the first ‘mRNA’ vaccine designed to fend off the SARS-CoV-2 virus was injected into Jennifer Haller in Seattle. Overview . Coronavirus-related Severe Acute Respiratory Syndrome (SARS-CoV) in 2002/2003, Middle-East Respiratory Syndrome (MERS-CoV) in 2012/2013, and especially the current 2019/2020 Severe Acute Respiratory Syndrome-2 (SARS-CoV-2) led to an unpredictable stress regarding the national health systems’ endurance worldwide (Song et al., 2019).
