Genesis Ramirez grips a digital timer, her legs swinging in a chair in the waiting room of the Meskwaki Tribal Health Center in Tama County, Iowa. The 17-year-old just got her second dose of the Pfizer COVID-19 vaccine. But she didn’t do it just to keep herself safe. “My family is very high risk, and I don’t want to bring anything back to them where I can’t help them,” Ramirez said. Ramirez isn’t a member of the Sac and Fox Tribe of the Mississippi, also known as the Meskwaki Nation.
