PA expands vaccine eligibility to ages 65 and older; UPMC vaccinates workers serving vulnerable populations As total U.S. Covid deaths pass 400,000 — with several effective vaccines developed — the puzzle is figuring out where the first limited doses will do the most good. In a multipronged effort to prioritize the biggest impact among Phase 1A groups, UPMC vaccinated workers with The Violence Prevention Initiative, the Neighborhood Resilience Project and Casa San Jose at their South Side clinic on Tuesday afternoon. By getting these community advocates inoculated, they hope to fight vaccine hesitancy in vulnerable, often minority populations, where Covid has had a disproportionately terrible effect.
