Targeting Dendritic Cells with Virus-like Particles: Toward Safer and More Immunogenic Vaccines.
(PubMed, Vaccines (Basel))
- "The newer "Qdenga" vaccine offers up to 80% efficacy after a year but provides suboptimal protection against DENV-3 in seronegative individuals... The administration of tetravalent dengue VLP vaccine in BALB/c mice did not result in adverse effects in acute or chronic toxicity evaluations. Therefore, the VLP supports progression toward clinical evaluation, with dendritic cell activation providing additional rationale."

Assessing the impact of vaccination against dengue viruses using long-term antibody measurements
(ASTMH 2025)
- "The results suggest that the vaccine's protection is skewed towards a single dominant serotype, and this protection is of shorter duration compared to natural infection. These preliminary findings align with previous evidence suggesting that Dengvaxia's effectiveness may be limited by immunodominance and interference."

Challenges in the Prevention and Treatment of Dengue Fever: An Emerging Issue.
(PubMed, Am J Trop Med Hyg)
- "Existing vaccines, such as Dengvaxia® (Sanofi Pasteur, Paris, France) and Qdenga® (Takeda Pharmaceutical Company, Tokyo, Japan), have demonstrated some efficacy; however, limitations include a lack of efficacy against certain regional DENV strains and the potential for antibody-dependent enhancement (ADE), particularly in individuals without previous DENV exposure...The intricate pathogenesis of DENV, involving complex virus-host interactions and immune responses, presents additional treatment challenges. In this review, the current challenges and advancements in DF prevention and treatment are examined, emphasizing the limits of existing vaccines and medicines while exploring novel approaches with potential for effectiveness in clinical settings."

Pathophysiology and clinical implications of dengue-associated neurological disorders.
(PubMed, Front Microbiol)
- "Although there are still challenges in reaching the ideal vaccination coverage, the introduction of potent vaccines like Dengvaxia and Qdenga provide an achievable option for prevention. Thorough study into DENV's neurological effects and treatment options is essential as the virus's geographic range is increased by climate change and international travel. Reducing the worldwide burden of dengue-related neurological complications requires addressing the intricate interactions between virological, immunological, and environmental variables."

Afucosylation of anti-dengue IgG is associated with enhanced susceptibility to dengue virus infection postvaccination.
(PubMed, Sci Transl Med)
- "Together, these findings support a model in which the presence of afucosylated IgG promotes virus replication, increasing the likelihood of productive infection upon DENV exposure. Moreover, these results highlight that IgG1 fucosylation is a predictor of risk for breakthrough DENV infection despite vaccination and support the importance of investigating strategies to regulate Fc fucosylation during vaccination."

State of the Art on Vaccine Development Against Dengue Infection: Scoping Review of the Literature.
(PubMed, Infect Dis Rep)
- "Vaccines were categorized into licensed (CYD-TDV and TAK-003), late-stage (TV003/TV005), and early-stage candidates (TDEN, DPIV, V180, TVDV)...TAK-003 (Qdenga®) demonstrated high efficacy against virologically confirmed dengue (VCD) and dengue-related hospitalization...Currently, TAK-003 is regarded as the best option for broad implementation, while TV003 and TV005 remain promising candidates due to their shorter schedule and robust immunogenicity. Further research is needed to optimize vaccine strategies in seronegative populations, immunocompromised subjects, older adults, and travelers."

A retrospective computational validation of a clinically evaluated recombinant envelope protein tetravalent dengue vaccine.
(PubMed, Int J Biol Macromol)
- "Licensed vaccines like Dengvaxia and Qdenga rely on yellow fever virus (YFV)-based vectors encoding DENV structural proteins, though ADE risks persist. However, limitations in predictive accuracy were noted, such as the erroneous docking of EDE1-C10 to EDIII, highlighting the need for improved modeling approaches incorporating structural dynamics and artificial intelligence (AI) tools. These results support further development of V180 and r2ED, while emphasizing the strengths and boundaries of computational vaccinology."

- "Complete genotype turnover of DENV-1 occurred in southeastern coastal China between 2019 and 2024, driven by displacement of lineage 1I_E.1 by 1I_K.2, with implications for local transmission patterns. Observed antigenic divergence between temporal isolates emphasizes the importance of sustained genomic monitoring and targeted intervention strategies tailored to circulating strains in this region."

From controversy to confidence: Strengthening dengue vaccines safety reporting.
(PubMed, Vaccine)
- "Dengue vaccines-Dengvaxia, Qdenga, and TV003/TV005 (NIH dengue vaccine) -offer potential for control, yet their implementation has been challenged by safety issues, including heightened risks in seronegative individuals, presumably due to antibody-dependent enhancement, though the precise mechanisms remain under investigation...The erosion of public trust following past vaccine controversies highlights the urgent need for transparency to bolster acceptance and inform policy. By integrating advanced surveillance with international cooperation, these measures can refine risk-benefit assessments, rebuild confidence in immunization programs, and maximize the protective impact of dengue vaccines, ultimately reducing the burden on vulnerable populations worldwide."

Dengue Vaccine Development and Deployment into Routine Immunization.
(PubMed, Vaccines (Basel))
- "Despite decades of research, only two dengue vaccines-CYD-TDV (Dengvaxia) and TAK-003 (Qdenga)-have been licensed to date, with limited implementation...While future vaccines, including mRNA and virus-like particle candidates, are under development, optimizing the use of currently available vaccines is crucial to reducing dengue's public health impact. Given the continued rise in cases, immediate action-combining vaccination with vector control-is essential to prevent further morbidity and mortality."

Development of New Live-Attenuated Vaccine Candidates Lacking Antibody-Dependent Enhancement (ADE) Against Dengue.
(PubMed, Vaccines (Basel))
- "Recently, a second licensed dengue vaccine, Qdenga®,Takeda, Singen, Germany), was approved and recommended by the WHO to be administered only in highly dengue-endemic countries, as it was not shown to elicit a robust immune response against DENV-3 and DENV-4 serotypes in dengue seronegative individuals. This review provides current insights to guide the development of a novel live-attenuated tetravalent dengue vaccine candidate that is effective against all DENV serotypes and safe from ADE. The efficacy and safety of the live-attenuated vaccine candidate should be further validated in in vivo studies."

Knowledge-based mitigation of the environmental risk of Orthoflavivirus live-attenuated vaccines by targeting viral encoded determinants for the mosquito attenuated phenotype.
(PubMed, Vaccine)
- "The mosquito-attenuated phenotype also ensures the safety of the licensed LAVs IMOJEV, Dengvaxia and QDENGA...This review discusses knowledge of orthoflaviviral encoded determinants for infection and dissemination in mosquito tissues which have potential utility for the rational design of candidate LAVs. Several attenuating mutations discovered to date are located within genomic regions that are conserved among orthoflaviviruses and can potentially support the establishment of a broadly effective attenuating strategy."
