Recombinant Vaccines Market. Recombinant vaccines are produced by using recombinant DNA technology or genetic engineering for the prevention of lethal diseases in human beings and animals. Recombinant vaccine is a biological preparation that provides active acquired immunity against a certain disease. Whereas individual being vaccinated produces antibodies against the protein antigen that protect a person from contracting the disease upon attack from the pathogenic microorganism. These vaccines functions on the immune response for diseases and to have preventive measures against diseases caused by various bacteria, and virus. These vaccines are much more advanced and effective as compare to conventional vaccines in the prevention of diseases such as malaria, typhoid, and human papillomavirus (HPV). Furthermore, Europe dominates the animal recombinant vaccines market as compared to other regions due to highly organized livestock and major demand for livestock products in Europe..

A new vaccine strategy could make flu shots cheaper, safer, and easier to produce. Using synthetic messenger RNA (mRNA) instead of proteins purified from viruses, German scientists have shown they can protect mice, ferrets, and pigs against influenza. "This is a very interesting new approach," says Hans-Dieter Klenk, a virologist at the University of Marburg in Germany who was not involved in the work. Now, most flu vaccines consist of hemagglutinin and neuraminidase, the two proteins covering the surface of the virus. To produce these molecules, the three predominant influenza strains are cultured in fertilized chicken eggs or, increasingly, in cell culture. Virus is then harvested and broken up so that the two proteins can be purified ...

Extensions of the folding problem have become particularly important in the last ten years or so because of interest in such possibilities as the preparation of totally synthetic vaccines. Can one look at the structure of a protein, preferably in three dimensions, and select areas on the surface which might be expected to have a strong tendency to fold properly even when chopped out of the total structure? I will describe to you a few experiments relating to this biological problem in a few moments. My own interest began with some work that was carried out with Ruth Arnon and Michael Sela at the Weizmann Institute on the so-called lysozyme loop -- a small disulphide-stabilized extension on the enzyme. When this loop was prepared synthetically and attached to a non-immunogenic carrier, injection into animals produced antibodies which did indeed recognize the parent enzyme molecule. One might say that this material constituted a synthetic vaccine against the lysozyme molecule. Through the activity ...
People who have repeated, unprotected exposure to HIV - yet remain uninfected - have a unique immune response that could serve as a model for protective vaccines, virologist Dr. Jay Levy reported at the 10th National AIDS Update Conference in San Francisco. Anti-viral drugs such as AZT and protease inhibitors do not prevent infection - and are unlikely to ever eradicate the virus from the body, asserted Levy. A synthetic vaccine that contains parts of the AIDS virus could trick the immune system into creating the right kind of response. Levys national study of the sex partners of infected people found, remarkably, that some individuals stay uninfected despite repeated episodes of unsafe sex. In studying patients blood in the laboratory, Levy found that if he attempted to create an infection in the presence of CD8 cells, viral replication was stopped.

Recombinant subunit vaccines are some of the safest and most effective vaccines available, but their high cost and the requirement of advanced medical infrastructure for administration make them impractical for many developing world diseases. Plant-based vaccines have shifted that paradigm by paving the way for recombinant vaccine production at agricultural scale using an edible host. However, enthusiasm for
HIV infection continues to spread at pandemic levels throughout the world. Control of this pandemic can only be achieved with the development of a safe and effective preventive HIV vaccine. A vaccine that will prevent HIV infection will elicit a strong immune response from both CD4 and CD8 cells. Recombinant adenovirus serotype vectors have been shown to elicit just such a response. The purpose of this study is to determine the safety and immunogenicity of the recombinant adenovirus serotype 26 preventive HIV-1 vaccine.. This study will last 12 months. Participants will be randomly assigned to one of four arms that will receive different doses of the vaccine or placebo administered via intermuscular injection. Participants in Arms 1, 2, and 3 will all receive 3 injections. Each injection will contain the same dose of vaccine. Arm 4 will receive 2 injections of a dose of vaccine that will be determined by the safety data from Arms 1, 2, and 3. Participants will be enrolled sequentially, from ...
Background. We report the first-in-human safety and immunogenicity assessment of a prototype Ad26 vector-based human immunodeficiency virus (HIV) vaccine in humans. Methods. Sixty Ad26-seronegative, healthy, HIV-uninfected subjects were enrolled in a randomized, double-blinded, placebo-controlled, dose-escalation phase 1 study. Five groups of 12 subjects received 10(9)-10(11) vp of the Ad26-EnvA vaccine (N = 10/group) or placebo (N = 2/group) at weeks 0 and 24 or weeks 0, 4, and 24. Safety and immunogenicity were assessed. Results. Self-limited reactogenicity was observed after the initial immunization at the highest (10(11) vp) dose. No product-related SAEs were observed. All subjects who received the Ad26-EnvA vaccine developed Ad26 NAb titers, EnvA-specific enzyme-linked immunosorbent assays (ELISA) titers, and EnvA-specific enzyme-linked immunospot assays (ELISPOT) responses. These responses persisted at week 52. At week 28 in the 10(9), 10(10), 10(11) vp 3-dose and the 10(10) and 5 × ...

The epidemic of HIV/AIDS is sweeping across the world. It is of great importance to figure out new ways to curb this disease. Epitope-based vaccine is one of these solutions. In this study, a chimeric gene was obtained by combination of a designed HIV-1 multi-epitope gene (MEG) and HIV-1 p24 gene. A recombinant plasmid pUTA2-MEGp24 was then constructed by inserting MEGp24 gene into the downstream of the promoter (ATI-P7.5x20) of fowlpox virus (FPV) transfer vector pUTA2. The recombinant plasmid and wild-type FPV 282E4 strain were then co-transfected into CEF cells and homologous recombination occurred. A recombinant virus expressing HIV-1 protein MEGp24 was screened by genome PCR and Western blot assay. Large scale preparation and purification of the recombinant fowlpox virus (rFPV) were then carried out. BALB/c mice were immunized intramuscularly with the rFPV for three times on day 0, 14 and 42. Mice were executed and sampled one week after the third inoculation. Anti-HIV-1 antibody in serum ...
The 2009 Army Posture Statement, cites a World Health Organization estimate of between 20 annd 50 percent of the worlds population being effected if a pandemic were to emerge. WHO forecasts it may be six to nine months before a vaccine for a pandemic virus strain becomes available." In a separate report on pandemic influenza, the WHO described several challenges to producing sufficient volumes of vaccine using current, egg based protein-production technology, including the likelihood that two doses per person could be required due to the absence of pre-existing immunity. In short, the potential for a pandemic exists and current technological limitations on defensive measures put the health and readiness of U.S. military forces at risk. A technological solution to increase the speed and adaptability of vaccine production is urgently needed to match the broad biological threat. DARPAs Blue Angel Program seeks to demonstrate a flexible and agile capability for the Department of Defence to ...

Pneumococcal surface protein A (PspA), a cell-surface protein present on all strains of pneumococci, has been shown to elicit protective antibody responses in mice in the absence of capsular polysaccharide. Whereas PspA is polymorphic, considerable cross-reactivity and cross-protection have been demonstrated among PspA proteins of pneumococci exhibiting different capsular and PspA serotypes. A gene segment encoding the nonrepetitive variable NH2-terminal portion of PspA has been cloned into three distinct recombinant Bacille Calmette-Guérin (rBCG) vectors, allowing for expression of PspA as a cytoplasmic or secreted protein, or a chimeric exported membrane-associated lipoprotein. All rBCG-PspA strains elicited comparable anti-PspA ELISA titers, ranging from 10(4) to 10(5) (reciprocal titers) in both BALB/c and C3H/HeJ mice. However, protective responses were observed only in animals immunized with the rBCG-PspA vaccines expressing PspA as a secreted protein or chimeric exported lipoprotein. In ...
Live recombinant viral vectors based on adenoviruses and poxviruses are among the most promising platforms for development of new vaccines against diseases such as malaria, tuberculosis, and HIV-AIDS. Vaccines based on live viruses must remain infectious to be effective, so therefore need continuous refrigeration to maintain stability and viability, a requirement that can be costly and difficult, especially in developing countries. The sugars sucrose and trehalose are commonly used as stabilizing agents and cryoprotectants for biological products. Here, we have exploited the ability of these sugars to vitrify on desiccation to develop a thermostabilization technique for live viral vaccine vectors. By slowly drying vaccines suspended in solutions of these disaccharide stabilizers onto a filter-like support membrane at ambient temperature, an ultrathin glass is deposited on the fibers of the inert matrix. Immobilization of two recombinant vaccine vectors-E1/E3-deleted human adenovirus type 5 and modified

According to an announcement made by India-based Bharat Biotech last week, the company has been working on two candidates for the Zika vaccine for more than a year. The vaccines in development - one of which is an inactivated for the virus, while the other is a recombinant vaccine containing antigens from the surface of the virus - could put the company ahead of others in the search for a Zika vaccine.. The company claims that they are likely the first to apply for a patent for their Zikavac vaccine candidate, which has already begun pre-clinical animal trials. Like all potential vaccines against the Zika virus - currently in development by companies such as Inovio, Sanofi and now Takeda - it could be many years before the vaccine is approved for widespread use among those at risk.. "Currently, our efforts are towards scale-up and characterization of the vaccine product," said a statement released by Bharat. "Our interest in Zika virus, an obscure virus when we started the project a year ago, ...
A malaria vaccine is a public health priority. In order to produce an effective vaccine, a multi-stage approach targeting both the blood and the liver stage infection is desirable. The vaccine candidates also need to induce balanced immune responses including antibodies, CD4+ and CD8+ T cells. Protein-based subunit vaccines like RTS,S are able to induce strong antibody response but poor cellular reactivity. Adenoviral vectors have been effective inducing protective CD8+ T cell responses in several models including malaria; nonetheless this vaccine platform exhibits a limited induction of humoral immune responses. Two approaches have been used to improve the humoral immunogenicity of recombinant adenovirus vectors, the use of heterologous prime-boost regimens with recombinant proteins or the genetic modification of the hypervariable regions (HVR) of the capsid protein hexon to express B cell epitopes of interest. In this study, we describe the development of capsid modified Ad5 vectors that ...

Conserved-element vaccines and methods for designing conserved-element vaccines - Embodiments of the present invention include conserved-element vaccines and methods for designing and producing conserved-element vaccines. A conserved-element vaccine ("CEVac") is a recombinant and/or synthetic vaccine that incorporates only highly conserved epitopes from an observed set of pathogen variants. The conserved epitopes are identified computationally by aligning biopolymer sequences, such as concatenated polypeptide sequences that together represent a pathogen proteome, corresponding to an observed set of pathogen variants, and computationally selecting conserved subsequences according to a number of subsequence-selection criteria. These subsequence-selection criteria may include a minimum conserved-subsequence length, a threshold frequency of occurrence of a particular monomer at each conserved, single-monomer position within a conserved subsequence, a threshold combined occurrence for a set of ...

NaturalNews) Biologists know that the thymus gland shrinks rapidly after puberty, but they have been unable to explain why this important gland turns to fat so quickly as people age. New research suggests that most peoples thymuses are missing some very important food-based antioxidants. If given the right amount of antioxidants, including Vitamin C and the enzyme catalase, the thymus can age more gracefully, keeping the immune system young and strong.. Exercising the thymus and giving it the right nutritional components gives it the capability to fight off pathogens into old age. Instead of retraining the immune system using synthetic vaccine chemicals and lab-grown viruses, healthy people can exercise their internal organs against all pathogens. They can let their intelligent natural defenses within their own thymus gland go to work. Research shows that if the thymus is given the right food-based antioxidants, it can thrive, keeping peoples immune systems young and strong as they age.. ...
