She and her husband Melvin volunteered to participate in coronavirus vaccine trials on the Navajo Nation. As coronavirus vaccines were being developed around the world, few Native American tribes signed up to participate. The reasons range from unethical practices of the past to the quick nature of the studies amid the pandemic. Native researchers say without participation from tribal communities, tribes won t know which vaccine might best be suited for their citizens. (Courtesy Arvena Peshlakai via AP).
