The OHA says these “breakthrough cases” are a reminder that no vaccine is 100% effective.
PORTLAND, Ore. Of the more than 700,000 Oregonians who have been fully vaccinated against COVID-19, 168 of them still tested positive for the virus, and three have died per year. April 2, state health officials said Thursday.
The Oregon Health Authority (OHA) said these so-called “breakthrough cases” are reported when people test positive for COVID-19 at least 14 days after their final dose of a vaccine series.
They have been reported in 25 of the state̵
“While the Pfizer, Moderna, and Johnson & Johnson COVID-19 vaccines are all highly effective in preventing severe COVID-19 disease and death, no vaccine is 100% effective and vaccine breakthroughs will occur,” the release said.
Health officials said many of the breakthrough cases were asymptomatic and were tested for other reasons. They said 11% of breakthrough cases were hospitalized within 30 days of their positive test, and most occurred in people older than 65 years or with underlying health conditions.
“The three deaths represent less than 2% of vaccine breakthrough cases,” the OHA said, adding that “none of the vaccine breakthrough cases were associated with a COVID-19 variant.”
To prevent vaccine breakthrough cases, the OHA recommends basic COVID safety measures such as masking, physical distance and avoiding social gatherings.
State and local epidemiologists continue to track and investigate cases of vaccine breakthroughs and work closely with the Centers for Disease Control and Prevention to gather information that can provide insight into the characteristics associated with vaccine breakthroughs.
On March 30, health officials in Washington reported 102 breakthrough cases out of 1.2 million fully vaccinated people.
