Most middle-aged and older Americans say they would roll up their sleeves for a vaccine that cut their risk of dementia. In a survey of 1,529 adults aged 50 and older published Sept. 21 in JAMA Network Open, 72% said they would be likely to get a low-cost, multidose vaccine that cut dementia risk in half for people at high risk.
There is an important catch: no vaccine to prevent dementia has been approved. Respondents were answering a hypothetical question about a product that does not exist, according to the USC Schaeffer Center for Health Policy & Economics, which led the research.
