The fight against cancer is leveling up. Researchers are tapping into our body’s own defense system — our immune system — as a powerful ally.
Enter nanodrug delivery systems (NDDS), the superheroes of modern medicine, inspired by the triumphs of vaccines like those for smallpox, polio, measles and COVID-19.
What’s a nanovaccine?
It turns out nanovaccines are tiny powerhouses — nanoparticles designed to supercharge the immune system to target and destroy cancer.
They merge traditional vaccine tech with cutting-edge nanoscience, offering superior tumour-targeting precision and long-lasting immune protection.
While existing cancer vaccines have made strides, issues like immune system “burnout” (losing their ability to effectively kill cancer cells) — or T-cell exhaustion — remain a hurdle.
With T cells too drained to fight cancer effectively, nanovaccines could swoop in, reinvigorating these cells and changing the game in cancer therapy.
It helps by shielding antigens (disease-busting agents), improving delivery to immune cells, and controlling antigen release, making vaccines more effective.
