(CNN) — A King County, Washington, woman originally from Portland has died from a rare blood clotting syndrome after receiving the Johnson & Johnson COVID-19 vaccine, according to a statement posted online by Public Health — Seattle & King County.
The woman, who was in her late 30s, was vaccinated on August 26 and died on September 7 from thrombosis with thrombocytopenia syndrome, known as TTS. It’s a rare and potentially deadly clotting event that has been linked with the J&J vaccine.
According to her obituary, she was an Oregon State graduate who was “vehemently opposed” to taking the vaccine, but eventually took it so she could continue volunteering at her children’s school.
Public Health — Seattle & King County said the diagnosis was confirmed by the US Centers for Disease Control and Prevention’s Clinical Immunization Safety Assessment Project. CDC has reported three other confirmed TTS deaths nationally, the release said.
