Prior to his hospitalization, Harmon shared a series of jokes on social media about vaccines.
“I got 99 problems but a vax ain’t one,” he wrote in June on Twitter.
In another tweet the same month, he made fun of the Biden administration’s outreach efforts to push vaccines.
“Biden’s door to door vaccine ‘surveyors’ really should be called JaCovid Witnesses. #keepmovingdork,” he wrote.
Harmon had been treated for pneumonia and critically low oxygen levels in the hospital, news station KCBS-TV reported.
Three days before his death, Harmon shared that he was being placed on a ventilator and asked his followers to pray for him.
“If you don’t have faith that God can heal me over your stupid ventilator then keep the Hell out of my ICU room, there’s no room in here for fear or lack of faith!” he wrote on Twitter.
