On April 8, OHA announced that it had identified 168 COVID-19 vaccine breakthrough cases in Oregon through April 2, including three deaths.
Vaccine breakthrough cases are defined as instances in which an individual received a positive COVID-19 test result at least 14 days after the final dose of their respective COVID-19 vaccine.
OHA public health officials say it’s a reminder that 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, and vaccine breakthrough cases will occur.
Fortunately, these cases remain uncommon.
The number of vaccine breakthrough cases identified in Oregon (168) represents a very small proportion of the more than 700,000 people in Oregon who have now been fully vaccinated against COVID-19.
OHA also noted that vaccine breakthrough cases can be prevented through our trusted safety measures, such as masking, physical distancing and avoiding social gatherings.
