A man who mocked Covid-19 vaccines on social media has died after a month-long battle with the virus. Stephen Harmon, a member of the Hillsong megachurch, had made a series of jokes about not having the vaccine. “Got 99 problems but a vax ain’t one,” the 34-year-old tweeted to his 7,000 followers in June. He was treated for pneumonia and Covid-19 in a hospital outside Los Angeles, where he died on Wednesday. In the days leading up to his death, Mr Harmon documented his fight to stay alive, posting pictures of himself in his hospital bed.
