Story summary

Researchers at the University of Massachusetts Amherst developed a nanoparticle-based vaccine that targets aggressive cancers in mice, including melanoma, pancreatic cancer, and triple-negative breast cancer.
88% of vaccinated mice remained cancer-free.
80% of mice vaccinated against melanoma survived 250 days.
All unvaccinated mice died within seven weeks.
The vaccine uses a "super adjuvant" composed of lipid nanoparticles that enhance the immune response.
