Every year millions of people in various tropical and subtropical regions encounter infection with dengue virus. Within the last few decades, its prevalence has increased up to 30-fold globally and presently these viruses have been transmitted in more than 100 countries. Scientists contributed to the development of tetravalent dengue vaccine by adopting numerous approaches including live vaccine, recombinant protein vaccine, DNA vaccine and virus-vectored vaccines. A vaccine should be genetically stable, equally effective against all serotypes, must be in-expensive and commercially available. Chimeric yellow fever virus-tetravalent dengue vaccine (CYD-TDV) is the first licensed vaccine developed by Sanofi Pasteur in December 2015, but this vaccine is not fully effective against different dengue virus serotypes (Sanofi Pasteur, Lyon, France). This review explores the advancements and challenges involved in the development of dengue vaccine.

Dengue hemorrhagic fever (DHF) is a disease caused by dengue virus (DENV1-4) and is transmitted by the Aedes aegypti mosquito. However, in 2015, official data from the member countries, WHO reported more than 3.2 million cases, including 10,200 severe dengue cases and 1181 deaths. The protein encoded by the genome of dengue virus. Major structural and non structural proteins making up the genome of dengue. From genomic data several studies found that mechanism of vaccine that can use in dengue virus. Several vaccines was establish in the world for example Live attenuated Vaccine, Chimera Vaccine, Subunit Vaccine, DNA vaccines DENV, Activated DENV Vaccine  - Whole Virus Particles, Activated  DENV Vaccine - Recombinant Subunit DENV, and DENV Vaccine 5.

AbstractThis report demonstrates a novel method to explore and evaluate the specific humoral/cellular immune response levels and immunoprotective effects of NMB0315 nucleic acid vaccine, recombinant protein vaccine and nucleic acid vaccine + recombinant protein vaccine in combination with mice, and to further explore the effective immunization method for NMB0315 vaccine. This route provides experimental basis. Nucleic acid vaccines [pcDNA3 1(+) / NMB0315] and recombinant protein vaccines (pET 30a / NMB0315) were prepared in large quantities, and immunologically or separately immunized female BALB/c mice were determined by nucleic acid priming protein boosting method. The specific humoral/cell immune response level, the in vitro bactericidal titer of immune serum, and the immunoprotective effect of the vaccine on mice infected with group B meningococcus were observed. Serum-specific IgG, IgG1, IgG2a and genital lavage fluids induced by NMB0315 nucleic acid vaccine group (pNMB0315 CpG), protein vaccine group (rNMB0315 FA) and combined immunization group (pNMB0315 CpG+rNMB0315 FA). The specific sIgA level reached the peak in the eighth week, and the A450 values were in vitro, and the in vitro bactericidal antibody titers of the nucleic acid vaccine group, the protein vaccine group and the combined immunization group were 1, 64, 1128, respectively. The immune protection rate of experimental mice were 70%, 95% and 80%, respectively. At 2, 4, 6, and 8 weeks, the ratio of IgG2a / IgG1 in the nucleic acid vaccine group, the recombinant protein vaccine group, and the combined immunization vaccine group was less than 1.

ABSTRACT Dengue virus infections can cause hemorrhagic fever, shock, encephalitis, and even death. Worldwide, approximately 2.5 billion people live in dengue-infested regions with about 100 million new cases each year, although many of these infections are believed to be silent. There are four antigenically distinct serotypes of dengue virus; thus, immunity from one serotype will not cross-protect from infection with the other three. The difficulties that hamper vaccine development include requirements of the natural conformation of the envelope glycoprotein to induce neutralizing immune responses and the necessity of presenting antigens of all four serotypes. Currently, the only way to meet these requirements is to use a mixture of four serotypes of live attenuated dengue viruses, but safety remains a major problem. In this study, we have developed the basis for a tetravalent dengue vaccine using a novel complex adenovirus platform that is capable of expressing multiple antigens de novo. This dengue vaccine is constructed as a pair of vectors that each expresses the premembrane and envelope genes of two different dengue virus serotypes. Upon vaccination, the vaccine expressed high levels of the dengue virus antigens in cells to mimic a natural infection and induced both humoral and cellular immune responses against multiple serotypes of dengue virus in an animal model. Further analyses show the humoral responses were indeed neutralizing against all four serotypes. Our studies demonstrate the concept of mimicking infections to induce immune responses by synthesizing dengue virus membrane antigens de novo and the feasibility of developing an effective tetravalent dengue vaccine by vector-mediated expression of glycoproteins of the four serotypes.
