PORTLAND, Ore. — The Oregon Health Authority revealed on Thursday that federal authorities are looking into the death of an Oregon woman after she received the Johnson & Johnson vaccine.
OHA said that it learned about the "potential adverse event" on April 20, two days after that information went to the CDC through the Vaccine Adverse Event Reporting System (VAERS), the national reporting system used to collect reports of reactions after vaccination.
According to the state, an Oregon woman in her 50s received a dose of the Johnson & Johnson vaccine before the pause recommendation was issued. Oregon ordered a halt to the vaccine on April 13.
"Until the investigation is complete, it cannot be concluded whether her death is related to the vaccine," OHA said.
The woman developed a rare and serious blood clot within two weeks of receiving her vaccination. The blood clot was seen in combination with very low platelet counts. OHA indicated that this was the same kind of serious blood clot that had been identified in six women around the country after receiving the vaccine, prompting the federal government to order a pause.
Healthcare providers are required to report certain adverse events following administration of COVID-19 vaccines, part of the FDA's emergency use authorization process. These generally include serious side effects, including death, hospitalization, or a life-threatening event.
At the time of the federal pause recommendation, about 7.5 million doses of the Johnson & Johnson vaccine had been administered in the United States, with more than 87,000 doses having been administered at locations throughout Oregon.
OHA said that this Oregon case will be added to the evidence currently being examined by federal authorities.
"The CDC and OHA will provide updates on any developments as they can be shared during the review and investigation process," Oregon officials said. "OHA continues to encourage all Oregonians to schedule an appointment to receive a COVID-19 vaccination when appointments become available."
