Fifty-one breakthrough cases involved residents of care facilities, senior living communities or other congregate care settings. There were 58 breakthrough cases in people aged 12 to 17. To date, there have been 13,166 COVID-19 vaccine breakthrough cases in Oregon. The median age of all cases was 48. Breakthrough cases have been reported in all 36 counties. Cases of COVID-19 are far more common in unvaccinated people. The report shows that the rate of COVID-19 in unvaccinated people is currently approximately five times higher than in vaccinated people.
