Personalized Cancer Vaccines Could Be Key Piece Of Cancer 'Moonshot'

In his State of the Union address last night, President Obama said he wants to "make America the country that cures cancer once and for all."

Here & Now's Jeremy Hobson talks with STAT senior science writer Sharon Begley about how those personalized vaccines - called neoantigen vaccines - work, and why they could become a central player in the push to cure cancer.
