JAMA study: Older adults may be excluded from many COVID-19 trials

More than half of all clinical trials evaluating vaccines and potential treatments for COVID-19 are "at high risk for excluding older adults," according to an analysis published Monday by JAMA Internal Medicine.

In addition, roughly one in four of the 847 trials reviewed by the researchers included an age "cutoff" that would exclude adults age 65 to 80, the data showed.
