Indiana passes 50% vaccination mark INDIANAPOLIS â Just over half of Hoosiers age 12 and older are now fully vaccinated against COVID-19, but northeast Indiana remains behind the curve. As of Friday, 2.89 million Hoosiers have completed either a two-dose Pfizer of Moderna vaccine or received a single-shot Johnson & Johnson vaccine, putting the state at 50.66% of its eligible population of just over 5.7 million fully vaccinated. Northeast Indiana, by comparison, still lags the state by a fair margin. The four-county area as a whole is only 36.25% vaccinated, although that regional average is dragged down by the state-worst LaGrange County and Noble County, which is tied for 14th-worst of Indianaâs 92 counties.
