The Oregon Health Authority reported a small number of cases Thursday in which Oregonians who had received their full vaccinations later received COVID-19.

Of the more than 700,000 Oregons now fully vaccinated, health officials identified only 1
It is a reminder that while the COFID-19 vaccines Pfizer, Moderna and Johnson & Johnson are all extremely effective in preventing serious COVID-19 disease and death, no vaccine is 100% effective and vaccine breakthroughs will occur. , ”The Oregon Health Authority said in a statement.
The cases occurred throughout the state in 25 counties. According to health officials, many of the people who have breakthrough cases experience asymptomatic infections. A small percentage of cases became ill enough to require hospitalization, and three people died. The state said most of the cases occurred in people over the age of 65 who had underlying health conditions.
“State and local epidemiologists continue to track and investigate vaccine breakthrough cases and work closely with the Centers for Disease Control and Prevention to gather information that may provide insight into vaccine breakthrough properties,” the health authority said in a statement.
Oregon is not alone in seeing small amounts of COVID-19 cases after vaccination. Washington State reported a similarly small amount of breakthrough cases in late March.
Health officials said people receiving vaccinations can limit the risk of breakthrough cases by continuing to practice basic health safety, even after being vaccinated, such as wearing masks when around other people, social distance and avoiding large gatherings. .
