A respiratory syncytial virus vaccine (RSV vaccine) is a vaccine which prevents infection by respiratory syncytial virus. No such vaccine exists. A 1998 paper reported that research toward developing a vaccine has advanced greatly over the past 10 years.[1] The desired vaccine would prevent lower respiratory infection from RSV in at-risk populations and if possible be useful in other populations with less risk.[1] A 2019 paper claimed that research toward developing a vaccine has advanced greatly over the past 10 years.[2] The same study predicted that a vaccine would be available within 10 years.[2] The current types of vaccines which are in research are particle-based vaccines, attenuated vaccines, protein subunit vaccines, or vector-based vaccines.[3] ...

Non-replicating vectors containing a nucleotide sequence coding for an F protein of respiratory syncytial virus (RSV) and a promoter for such sequence, preferably a cytomegalovirus promoter, are described for in vivo immunization. Such non-replicating vectors, including plasmids, also may contain a further nucleotide sequence located adjacent to the RSV F protein encoding sequence to enhance the immunoprotective ability of the RSV F protein when expressed in vivo. Such non-replicating vectors may be used to immunize a host against disease caused by infection with RSV, including a human host, by administration thereto, and may be formulated as immunogenic compositions with pharmaceutically-acceptable carriers for such purpose. Such vectors also may be used to produce antibodies for detection of RSV infection in a sample.

Vaccines prevent infectious disease largely by inducing protective neutralizing antibodies against vulnerable epitopes. Several major pathogens have resisted traditional vaccine development, although vulnerable epitopes targeted by neutralizing antibodies have been identified for several such cases. Hence, new vaccine design methods to induce epitope-specific neutralizing antibodies are needed. Here we show, with a neutralization epitope from respiratory syncytial virus, that computational protein design can generate small, thermally and conformationally stable protein scaffolds that accurately mimic the viral epitope structure and induce potent neutralizing antibodies. These scaffolds represent promising leads for the research and development of a human respiratory syncytial virus vaccine needed to protect infants, young children and the elderly. More generally, the results provide proof of principle for epitope-focused and scaffold-based vaccine design, and encourage the evaluation and further ...

Vaccination with the respiratory syncytial virus (RSV) attachment (G) protein results in immune-mediated lung injury after natural RSV infection with pathogenic features characteristic of an exaggerated Th2 response. Here we demonstrate that approximately half of the CD4(+) T cells infiltrating the lungs of G-primed mice utilize a single V beta gene (V beta 14) with remarkably limited CDR3 diversity. Furthermore, elimination of these V beta 14-bearing CD4(+) T cells in vivo abolishes the type 2-like pulmonary injury. These results suggest that a novel subset of CD4(+) T cells may be crucial in the development of pathology during human RSV infection and that genetic or environmental factors prior to or at the time of G antigen exposure may affect the commitment of this discrete antigen-specific T cell subset to Th2 differentiation.

Respiratory syncytial virus (RSV) is a major cause of respiratory tract infections in infants, but an effective vaccine has not yet been developed. An ideal vaccine would elicit protective antibodies while avoiding virus-specific T-cell responses, which have been implicated in vaccine-enhanced disease with previous RSV vaccines. We propose that heterologous proteins designed to present RSV-neutralizing antibody epitopes and to elicit cognate antibodies have the potential to fulfill these vaccine requirements, as they can be fashioned to be free of viral T-cell epitopes. Here we present the design and characterization of three epitope-scaffolds that present the epitope of motavizumab, a potent neutralizing antibody that binds to a helix-loop-helix motif in the RSV fusion glycoprotein. Two of the epitope-scaffolds could be purified, and one epitope-scaffold based on a Staphylococcus aureus protein A domain bound motavizumab with kinetic and thermodynamic properties consistent with the free epitope

The state of maternal immunization is much different now than from when Gregory M. Glenn, MD, first started in healthcare. It was a widely studied field, but still not as practiced in pregnant women.. Now, Glenn, president of Research & Development for Novavax Inc., and his team of investigators are at the cusp of revolutionary development for maternal vaccines.. The Maryland-based clinical-stage vaccine company intends to share data in the following weeks on its first clinical trial of an investigative respiratory syncytial virus (RSV) vaccine in third-trimester pregnant women. Its findings and eventual successive studies could alter the scope of care for RSV, the most common cause of bronchiolitis and pneumonia in children younger than 1 year old in the US.. The trial-which has been ongoing for 4 years and has assessed the potential vaccine in about 3000 treatment-eligible pregnant subjects in that time-has been carried out by teams comprised of RSV, vaccination, and maternity-care specialists ...

In 1966, a decade after RSV was discovered, US National Institutes of Health researchers began testing an RSV vaccine made of a virus killed with formalin-an aqueous solution of formaldehyde. The trial was a disaster, McLellan says. Although infants who got the vaccine developed antibodies against the virus, they were not protected from infection. Instead, the vaccine seemed to make the disease worse. Some 80% of infants who got the shot were hospitalized after an RSV infection, compared with 5% of infants in the control group. Two vaccinated babies died from the infection. The tragedy tainted the RSV vaccine field for decades.. ...

Respiratory syncytial virus (RSV) infection is a severe threat to young children and the elderly. Despite decades of research, no vaccine has been approved. Notably, instead of affording protection, a formalin-inactivated RSV vaccine induced severe respiratory disease including deaths in vaccinated children in a 1960s clinical trial; however, recent studies indicate that other forms of experimental vaccines can also induce pulmonary pathology in pre-clinical studies. These findings suggest that multiple factors/pathways could be involved in the development of enhanced respiratory diseases. Clearly, a better understanding of the mechanisms underlying such adverse reactions is critically important for the development of safe and efficacious vaccines against RSV infection, given the exponential growth of RSV vaccine clinical trials in recent years. By employing an integrated systems biology approach in a pre-clinical cotton rat model, we unraveled a complex network of pulmonary canonical pathways ...

This week has been a long one. Im happy that its over! The babies were still sick at the beginning of the week and actually went to the doctor on Monday. Pat took the day off of work and grandpa went with them. We were told that yep, they have colds, surprise, surprise! The good news out of all of this though is that we found out our insurance will cover the RSV vaccine, which is awesome! The vaccine is a series of 6 shots, one per month that they give to preemies to help protect them during flu season. Since they were born with under-developed lungs they are at higher risk for getting RSV. It costs $1100 per shot per baby so we are very lucky! They got weighed in at the doctor as well and Seamus is 13 lbs 5oz, Katie is 12 lbs 12oz, and Helena is 11 lbs exactly. They havent quite caught up to where they should be yet but theyre getting there! The other good news from this week is that Seamus has been cut down to going to therapy only one time per week.

Human respiratory syncytial virus (RSV) is the main viral cause of respiratory tract infection in infants as well as some elderly and high-risk adults with chronic pulmonary disease and the severely immunocompromised. So far, no specific anti-RSV therapeutics or effective anti-RSV vaccines have been reported. Only one humanized monoclonal antibody, Palivizumab, has been approved for use in high-risk infants to prevent RSV infection. Ribavirin is the only drug licensed for therapy of RSV infection, but its clinical use is limited by its nonspecific anti-RSV activity, toxic effect, and relatively high cost. Therefore, development of novel effective anti-RSV therapeutics is urgently needed. The RSV envelope glycoprotein F plays an important role in RSV fusion with, and entry into, the host cell and, consequently, serves as an attractive target for developing RSV entry inhibitors. This article reviews advances made in studies of the structure and function of the F protein and the development of RSV entry

The respiratory syncytial virus (RSV) fusion glycoprotein (F) can interact with the small intracellular GTPase RhoA, and peptides derived from RhoA inhibit RSV replication. These observations initially suggested that RhoA-derived peptides might inhibit RSV replication by disrupting an in vivo interaction between RSV F and RhoA. However, recent data indicate that the antiviral activity of RhoA-derived peptides is not due to competitive inhibition of an hypothesized F-RhoA interaction, but is rather a function of the peptides intrinsic biophysical properties. We summarize here what is known about the mechanism of RSV inhibition by these peptides and give our opinion regarding the potential implications of this work with regards to RSV biology, and to the development of antiviral agents targeting RSV and other enveloped viruses.. ...

Severity of respiratory syncytial virus (RSV) infection ranges widely. To what extent the local immune response is involved in RSV disease pathogenesis and which markers of this response are critical in determining disease severity is still matter of debate.. The local immune response was studied in nasopharyngeal aspirates (NPAs) during RSV infection. Forty-seven potential markers of disease severity were analysed in a screening cohort of RSV-infected infants with mild disease at home (n=8), hospitalised infants (n=10), and infants requiring mechanical ventilation (n=7). Results were confirmed in a cohort of infants hospitalised for RSV infection (n=200). Finally, genetic validation was studied in a cohort of infants hospitalised for RSV infection (n=465) and healthy controls (n=930).. TIMP metallopeptidase inhibitor (TIMP)-1 was higher in the NPAs of hospitalised infants compared to the NPAs of infants at home (1,199 vs 568 ng·mL−1, p,0.0001). Similar results were found for matrix ...

We are at an opportune time to step up efforts to prevent RSV infection in children and elderly populations. With more than 65 candidate vaccines in clinical development, it is likely that an RSV vaccine will be available in the next five to seven years. Moreover, a range of treatments for RSV are also being developed. Our findings will provide better evidence to understand how these interventions should be best introduced, not only in Europe but also the rest of the world.. ...

n/N is not naive. It is the maximum likelihood estimator. It is wrong to give more weight to the no-knowledge assumption of a uniform prior distribution, than to the data-supported n/N estimate. no-knowledge Bayes techniques are not a good substitute for data. Bayes prior distribution should be based on something applicable to the experiment being done (prior knowledge, a conservative assumption, etc.). It is better to directly use the data and a maximum likelihood estimator than to influence the results with a no-knowledge Bayes prior. You might also consider the technique of bootstrapping if you are not happy using the MLE directly. I dont know if the result will be different ...

Respiratory syncytial virus is one of the most important causes of respiratory tract infection in infants and the elderly worldwide. Transmitted by direct and indirect contact, respiratory syncytial virus spreads as readily in the hospital as it does in the community, making healthcare-associated infection common. Respiratory syncytial virus is a major preventable healthcare-associated infection with frequent outbreaks that can lead to high mortality rates in healthcare facilities. Proper infection prevention measures, including hand hygiene, standard and contact precautions, cohorting, and rapid diagnostic techniques, are critical in controlling the spread of respiratory syncytial virus in healthcare facilities and establishing a culture of patient and employee safety. Timely implementation of standard infection control measures will minimize its medical and economic impact.. ...

Several broad categories of patients are most vulnerable to RSV infection. These include:. premature infants and all infants less than 1 year of age, children 2 years old with cardiac disease or chronic lung disease (for example, asthma, cystic fibrosis, etc.), those of any age with a compromised immune system, and those 65 years of age or older. Is respiratory syncytial virus (RSV) contagious? Respiratory syncytial virus (RSV) is contagious. In the United States, its the most common cause of inflammation of the small airways in the lungs (bronchiolitis) and of pneumonia in children under 1 year of age. It also is significant cause of respiratory illnesses in older adults. Nearly all children in the U.S. will have been infected by RSV by 2 years of age. RSV usually causes a mild respiratory infection, but it can occasionally cause more serious infections that require hospitalization from breathing compromise with bronchiolitis or pneumonia. RSV was discovered in 1956 (isolated from a chimpanzee ...

Currently, there is no licensed vaccine to prevent infection by RSV. There has been tremendous interest and research in RSV vaccine discovery, given the viruss significant disease burden and the relative lack of disease-specific therapies. However, vaccine development has faced significant obstacles that have blocked its progress. Among these are infant-specific factors, such as the immature infant immune system and the presence of maternal antibodies, which make infantile immunization difficult.[9]. Attempts to develop an RSV vaccine began in the 1960s with a formalin-inactivated vaccine that was developed for use in infants and children. While a similar method was used to the create a safe and effective poliovirus vaccine, this vaccine resulted in a dangerous phenomenon that came to be known as vaccine-associated enhanced respiratory disease (VAERD). In VAERD, the vaccinated infants went on to develop significantly worse respiratory disease than non-vaccinated infants during subsequent ...

Author Summary Respiratory syncytial virus (RSV) is a leading cause of pediatric lower respiratory tract disease. RSV has two IFN-I antagonist proteins, NS1 and NS2. In this study, we infected primary human dendritic cells with recombinant RSV from which the NS1 and/or the NS2 genes were deleted, and evaluated effects on the proliferation of autologous T lymphocytes during co-culture in vitro. We found that NS1, but not NS2, has a suppressive effect on two cell populations, namely CD103+ CD8+ T cells and Th17 cells, which are known to protect against viral respiratory infections, and a stimulatory effect on Th2 cells, which are involved in enhanced disease caused by RSV. We also provide evidence that these effects are not due to suppressed IFN-I production or signaling in dendritic cells or T cells, and that they likely result from reduced maturation of dendritic cells caused by the NS1 protein.

Respiratory syncytial virus (RSV) is the leading cause of hospitalization especially in young children with respiratory tract infections (RTI). Patterns of circulating RSV genotypes can provide a better understanding of the molecular epidemiology of RSV infection. We retrospectively analyzed the genetic diversity of RSV infection in hospitalized children with acute RTI admitted to University Hospital Heidelberg/Germany between October 2012 and April 2013. Nasopharyngeal aspirates (NPA) were routinely obtained in 240 children younger than 2 years of age who presented with clinical symptoms of upper or lower RTI. We analyzed NPAs via PCR and sequence analysis of the second variable region of the RSV G gene coding for the attachment glycoprotein. We obtained medical records reviewing routine clinical data. RSV was detected in 134/240 children. In RSV-positive patients the most common diagnosis was bronchitis/bronchiolitis (75.4%). The mean duration of hospitalization was longer in RSV-positive compared to

Respiratory syncytial virus (RSV) is a common virus that can have varying effects ranging from mild cold-like symptoms to mortality depending on the age and immune status of the individual. We combined mathematical modeling using ordinary differential equations (ODEs) with measurement of RSV infection kinetics in primary well differentiated human airway epithelial (HAE) cultures in vitro and in immunocompetent and immunosuppressed cotton rats to glean mechanistic details that underlie RSV infection kinetics in the lung. Quantitative analysis of viral titer kinetics in our mathematical model showed that the elimination of infected cells by the adaptive immune response generates unique RSV titer kinetic features including a faster time scale of viral titer clearance than viral production, and a monotonic decrease in the peak RSV titer with decreasing inoculum dose. Parameter estimation in the ODE model using a non-linear mixed effects approach revealed a very low rate (average single cell lifetime ...

In a first, scientists used computer simulations to identify the vaccines most likely to be effective against respiratory syncytial virus (RSV), the most common cause of infant severe pneumonia worldwide.. Although there is no vaccine yet available for RSV, a viral infection that annually kills up to 200,000 children under five globally, a study published today in Vaccine suggested that the most effective vaccine would be one that stops RSV from spreading in the general population rather than one that completely prevented disease in RSV-infected individuals.. This approach radically alters the way we decide which promising vaccine to develop. Choosing which new vaccines to develop from many possible candidates is an expensive process. As using mathematical modelling helps do that more efficiently, we expect that the pharmaceutical industry will use this approach more and more in the future, says study leader Prof. Lisa White, of the University of Oxford, and Head of Mathematical and Economic ...

Summary Intergenic and flanking gene regions for the 1C-1B, 1B-N, N-P, M-1A, G-F and F-22K gene junctions of respiratory syncytial virus strain 18537, representing antigenic subgroup B, were determined by dideoxynucleotide sequencing of polycistronic cDNAs and mRNAs. Comparison with their counterparts from the subgroup A strain A2 showed that the intergenic sequences were not conserved within or between the strains. Flanking non-coding gene sequences also were generally not conserved except for the highly conserved gene-start and gene-end transcription signals. The sequence of the overlap between the 22K and L genes was conserved almost exactly between the two subgroups.

NFID provides resources to educate healthcare professionals about the burden of respiratory syncytial virus (RSV), a common cause of acute respiratory illness in older adults, with the risk of serious infection increasing with age.

We have previously shown that respiratory syncytial virus (RSV) assembly occurs within regions of the host-cell surface membrane that are enriched in the protein caveolin-1 (cav-1). In this report, we have employed immunofluorescence microscopy to further examine the RSV assembly process. Our results show that RSV matures at regions of the cell surface that, in addition to cav-1, are enriched in the lipid-raft ganglioside GM1. Furthermore, a comparison of mock-infected and RSV-infected cells by confocal microscopy revealed a significant change in the cellular distribution of phosphocaveolin-1 (pcav-1). In mock-infected cells, pcav-1 was located at regions of the cell that interact with the extracellular matrix, termed focal adhesions (FA). In contrast, RSV-infected cells showed both a decrease in the levels of pcav-1 associated with FA and the appearance of pcav-1-containing cytoplasmic vesicles, the latter being absent in mock-infected cells. These cytoplasmic vesicles were clearly visible between 9

Respiratory Syncytial Virus (RSV) is an important human pathogen associated with substantial morbidity and mortality. The present study tested the hypothesis that RSV infection would increase matrix metalloproteinase (MMP)-9 expression, and that MMP-9 inhibition would decrease RSV replication both in vitro and in vivo. RSV A2 infection of human bronchial epithelial cells increased MMP-9 mRNA and protein release. Cells transfected with siRNA against MMP-9 following RSV infection had lower viral titers. In RSV infected wild-type (WT) mice, MMP-9, airway resistance and viral load peaked at day 2 post infection, and remained elevated on days 4 and 7. RSV infected MMP-9 knockout (KO) mice had decreased lung inflammation. On days 2 and 4 post inoculation, the RSV burden was lower in the MMP-9 KO mice compared to WT controls. In conclusion, our studies demonstrate that RSV infection is a potent stimulus of MMP-9 expression both in vitro and in vivo. Reduction of MMP-9 (via siRNA knockdown, and in MMP-9 KO mice

The worldwide Respiratory Syncytial Virus Diagnostics Market is poised to grow at a CAGR exceeding 10% over the forecast period (2016 to 2024). It stood at USD 625 million in 2015. High prevalence of neonatal infections & viral diseases and the need for early RSV detection mechanisms for infants are key drivers of this industry. Respiratory syncytial virus harms the respiratory tract, the immune system, the heart, and lungs; thus leading to serious illnesses. It mainly affects infants in the age group of 0 to 11 months.. However, there are instances of people above the age of 60 years being afflicted by this virus. This is essentially because of weak immunity. Some patients may even need hospitalization. Clinical symptoms of the RSV infection can seldom be distinguished from the symptoms of other respiratory disorders. Hence, there is a pressing need to develop precise & accurate diagnostic solutions for such a disease.. The global RSV Diagnostics market is categorized on the basis of products, ...

Temporary Exclusion Criteria for All Participants:. The following are temporary or self-limiting conditions and, once resolved, the person may be enrolled, if otherwise eligible. If the period of temporary exclusion is more than 56 days for adults or more than 30 days for RSV-seronegative children, the person will need to be rescreened. If the period of temporary exclusion is more than 56 days for RSV-seropositive children, a pre-inoculation serum antibody will need to be collected.. ...

RSV is the most common cause of respiratory infections in children. Most children are infected with RSV during the first year of life and almost all have been infected by age two. However, immunity is temporary and most people will contract it again as adults.

The usual incubation period is 2 to 4 days, followed by the onset of rhinitis; severity of illness progresses to a peak within 1 to 3 days.

ATLANTA, Feb. 01, 2017 (GLOBE NEWSWIRE) -- Aviragen Therapeutics, Inc. (Nasdaq:AVIR), a company focused on the discovery and development of the next generation of direct-acting antivirals to treat infections that have limited therapeutic options, today announced top-line data from its double-blind, placebo-controlled Phase 2a study of BTA585 ...

Respiratory syncytial virus (RSV) is a major cause of respiratory illness in young children. RSV infection produces a variety of signs and symptoms involving different areas of the respiratory tract, from the nose to the lungs. Laboratory mice are infectable with human RSV but only semi-permissive for viral replication. Different strains and sub-strains of virus have different properties in the mouse model. We therefore cloned and tested a range of variants of A2 strain, finding one that is especially good at infecting and causing disease in mice. Virus storage: must be stored at minus 80 degrees centigrade or below. Needs to be thawed and rapidly used (unstable at room temperature for about one hour). Licensees are permitted to grow up stocks of their own according to supplied protocols. Internal case number: 7013. ...
