OHA Releases Latest Monthly Update on Vaccine Breakthrough Cases
Through July 31st, Oregon Health Authority has identified 4,196 COVID-19 vaccine breakthrough cases. Vaccine breakthrough cases are defined as instances in which an individual received a positive COVID-19 test result at least 14 days following the completion of any COVID-19 vaccine series. Vaccine breakthrough cases remain rare. While the Pfizer, Moderna and Johnson & Johnson COVID-19 vaccines are all highly effective at preventing severe COVID-19 illness and death, no vaccine is 100% effective.
In July, there were 12,514 cases of COVID-19; 81% of these cases were unvaccinated1.
The median age of breakthrough cases is 51 years and 27% have occurred in individuals older than 65. These cases have been reported in 36 counties and all health care preparedness regions. Of the 4,196 reported vaccine breakthrough cases, approximately 7% were observed in individuals who reside in long-term care facilities or other congregate care settings. Here in our metro, we had 281 breakthrough cases, as defined by the OHA.
