A New 'Nanoparticle Vaccine' Prevented Cancer In Mice, Study Says

The vast majority of mice that received the vaccine warded off repeated exposure to cancer cells, but the applications for humans are still not known.

Scientists have developed a unique nanoparticle vaccine that prevented the development of multiple forms of cancer in mice, reports a study published in Cell Reports Medicine on Thursday. 

Eighty percent of mice that received the novel vaccine and were subsequently exposed to cancerous cells did not develop tumors and survived to the end of the 250-day long experiment. In contrast, all of the mice that received different vaccine formulations, or remained unvaccinated, developed tumors and none survived longer than 35 days.
