This Dengue Virus Vaccine Patch Could Provide Immunity Needle-Free

A dengue virus vaccine prospect, developed by The University of Queensland (UQ), has had promising results in animal model testing. It produced a protective reaction in immune dengue-infected mice. The exciting milestone provides hope to many since 390 million people are infected every year – and it’s a notoriously challenging pathogen to deal with. The most exciting part is how the vaccine isn’t injected but applied to the skin via a high-density microarray patch (HD-MAP) – more simply put, microneedle patches. Dengue fever is one of the tropical regions’ most prevalent diseases. Mosquitos carry the virus and infect people when they bite them. According to Jovin Choo, a UQ Ph.D. candidate who participated in the study,  this research could lead to a readily administered vaccine that could halt the devastation of dengue fever worldwide.  For now, efforts to tackle it mainly focus on prevention. Preventative measures involve targeting mosquitoes with traps, making the insect resistant to the virus, genetic engineering to reduce their numbers, or exposing them to bacteria that stop the virus from growing. There is one vaccine currently available, known as Dengvaxia, but it’s not v
