COVID-19 Vaccine Breakthrough Cases in Oregon

Oregon Health Authority has identified 168 COVID-19 vaccine breakthrough cases—when vaccinated individuals test positive for the virus—through April 2, including three deaths.

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.

These cases have been reported in 25 counties and all health care preparedness regions (Region 1: 76; Region 2: 29; Region 3: 27; Region 5: 9; Region 6: 4; Region 7: 17; Region 9: 6). OHA is not reporting the regions in which the deaths took place.

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 any COVID-19 vaccine series. Vaccine breakthrough cases can be prevented by basic public health interventions, such as masking, physical distancing and avoiding social gatherings.

The number of vaccine breakthrough cases identified in Oregon represents a very small proportion of the more than 700,000 people in Oregon who have been fully vaccinated against COVID-19. Many of the vaccine breakthrough cases identified experienced asymptomatic infection and were tested for other reasons. Eleven percent (n=19) of the vaccine breakthrough cases were hospitalized within the 30 days following their positive test, and most occurred in people older than 65 or with underlying health conditions. The three deaths represent fewer than 2% of the vaccine breakthrough cases, and none of the vaccine breakthrough cases were associated with a COVID-19 variant.

State and local epidemiologists are continuing to track and investigate vaccine breakthrough cases and are working closely with the Centers for Disease Control and Prevention to collect information that may provide insight into characteristics associated with vaccine breakthrough.

Oregon reports 678 new confirmed and presumptive COVID-19 cases, 5 new deaths

There are five new COVID-19 related deaths in Oregon, raising the state’s death toll to 2,439, the Oregon Health Authority reported at 12:01 a.m. Thursday.

Oregon Health Authority reported 678 new confirmed and presumptive cases of COVID-19 as of 12:01 a.m. Thursday, bringing the state total to 168,795.

Vaccinations in Oregon

Thursday, OHA reported that 50,429 new doses of COVID-19 vaccinations were added to the state immunization registry. Of this total, 27,783 doses were administered on April 7 and 22,646 were administered on previous days but were entered into the vaccine registry on April 7.

The 50,429 doses submitted to the state’s immunization tracking system on April 7 was the highest number of COVID-19 vaccine doses entered into the database on a single day since the COVID-19 vaccines began to be administered in Oregon. The 7-day running average is now 34,733 doses per day.

As of today, 824,299 people have completed a COVID-19 vaccine series. There are 522,780 people who have had at least one dose.

Oregon has now administered a total of 1,083,978 doses of Pfizer, 971,012 doses of Moderna and 61,539 doses of Johnson & Johnson COVID-19 vaccines.

Cumulative daily totals can take several days to finalize because providers have 72 hours to report doses administered and technical challenges have caused many providers to lag in their reporting. OHA has been providing technical support to vaccination sites to improve the timeliness of their data entry into the state’s ALERT Immunization Information System (IIS).

To date, 1,340,235 doses of Pfizer, 1,212,800 doses of Moderna and 185,500 doses of Johnson & Johnson COVID-19 vaccines have been delivered to sites across Oregon.

These data are preliminary and subject to change.

OHA’s dashboards provide regularly updated vaccination data, and Oregon’s dashboard has been updated Thursday.

COVID-19 hospitalizations

The number of hospitalized patients with COVID-19 across Oregon is 168, which is three fewer than yesterday. There are 38 COVID-19 patients in intensive care unit (ICU) beds, which is four fewer than yesterday.

The total number of patients in hospital beds may fluctuate between report times. The numbers do not reflect admissions per day, nor the length of hospital stay. Staffing limitations are not captured in this data and may further limit bed capacity.
