PORTLAND, Ore — The Oregon Health Authority (OHA) on Friday announced that four Oregonians who have been fully vaccinated later tested positive for COVID-19.
Two of the "breakthrough cases" are in Lane County and the other two are in Yamhill County, the OHA said.
The four people tested positive at least 14 days after receiving their final dose of the vaccine. Their illnesses range from asymptomatic to mild symptoms.
OHA and public health officials are investigating the origin.
"Such cases are not unexpected," the OHA said in a news release. "Clinical trials of both vaccines presently in use included breakthrough cases. In those cases, even though the participants got COVID-19, the vaccines reduced the severity of illness."
The OHA said based on what is known about vaccines for other diseases and early data from clinical trials, experts believe the current vaccines in use are "very effective."
