something they have to do to protect themselves and others around them. if the definition changes on federal level, it will help businesses, universities making their own rules about what it means to be vaccinated. but i also hope that doctors, hospitals, pharmacies will take matters into their own hands, and if they haven t already, call their patients, not just elderly patients in nursing homes, but all patients eligible for booster but haven t rev received them, because that is more than half of americans fully vaccinated as of the current defrgs but have not yet gotten their boosters even though they re eligible and overdue for their boosters. that approach you re talking about seems the most effective way to convince people to do that, outreach from their own care providers seems to be one of the things we ve learned in this pandemic. only about a quarter of the u.s. population the fully vaccinated and boo sted. if this definition changes, the country has a long way to go again.
