In remote regions of Africa, where malaria cases are most prevalent, refrigeration facilities and medical personnel are often scarce. Even when vaccines are available, the lack of infrastructure has created a vicious cycle in which they cannot be properly administered. Now, Busan-based bio venture SNVIA Co., Ltd. aims to address this challenge with a microneedle vaccine patch. Instead of a traditional injection, the company is developing a malaria prevention method in the form of a disposable, bandage-like patch. The 1 cm² microneedle patch contains dozens of microscopic needles as thin as a strand of hair. When applied to the skin, it delivers the vaccine beneath the surface in a manner similar to a conventional injection, thereby inducing an immune response. Even more remarkable is its storage stability. While conventional injectable vaccines require cold chain system, but the microneedle patch remains stable for approximately four weeks even at high temperatures of 37°C (98.6°F). This makes it possible to distribute the vaccine reliably during Africa’s hot weather environment and in remote villages without access to refrigeration.
