An Oregon woman has died following immunization with the Johnson & Johnson vaccine.

Information from the Oregon Health Authority said they were informed of the situation by the Centers for Disease Control and Prevention.

OHA was notified of the potential adverse event on Tuesday, two days after the CDC was notified on Sunday. The woman, in her 50s, received the vaccine before the pause order on its use was issued. OHA said until the investigation is complete, it cannot be concluded whether her death is related to the vaccine.

OHA said the woman developed a rare but serious blood clot within two weeks following vaccination. This blood clot was seen in combination with very low platelets. Prior to the issuance of the pause, cases of this serious blood clot had been identified among six women around the country who received the vaccine.

At the time of the CDC pause recommendation, about 7.5 million doses of the Johnson & Johnson vaccine had been administered in the United States. More than 87,000 doses had been administered at locations throughout Oregon.
