Can the shingles vaccine actually lower the risk of dementia?

A new study out of the Stanford University School of Medicine showed that older adults who received the shingles vaccine were 20% less likely to develop dementia over the next seven years than those who didn't receive the vaccine. But what does this mean in terms of finding a tried and true cure to dementia, and who's more at risk than others? Host Pooja Handa speaks to Sabina Vohra-Miller, founder of Unambiguous Science, about the study's findings and what it for the future of the disease.
