Abstract
Dengue fever remains a persistent viral threat, affecting millions of families every year, turning a simple mosquito bite into a potentially life-threatening emergency. This disease remains a constant burden on our global healthcare system, demanding innovative solutions to protect worldwide communities. While many researchers discuss general treatments, preventions and modern medical interventions, there is often a lack of focus on how current, cutting-edge molecular and genetic tools are employed to engineer dengue strains as vaccine candidates. Therefore, in this paper, we explore the recent genetic strategies, such as targeted virulent gene deletions, CRISPR-Cas inactivation, and viral codon deoptimization approaches used to attenuate or inactivate Dengue viruses specifically. Assays and techniques used in validating Dengue viral attenuation or inactivation are also discussed in detail, highlighting the importance of the balance between safety and immunogenicity for Dengue vaccine uses. The article also briefly elaborates the complex biological challenges and safety concerns that centre on Dengue vaccine developments. By bridging the gap between advanced genetics and public health, this review provides readers with a comprehensive understanding of how modern genetics is paving the way for the next generation of safe and effective Dengue vaccines.
