Meanwhile, the Crater Health District releases a FAQ list about the Johnson & Johnson investigation. The Progress-Index PETERSBURG — The investigation into issues with the Johnson & Johnson COVID-19 vaccine has forced localities around the area to hit the pause button on mobile vaccination clinics and make on-the-fly switches in what will be dosed out at some of the more stationary clinics. A news release from the city of Petersburg Wednesday morning said it was cancelling all mobile vaccination clinics "until further notice" while the Centers for Disease Control and Prevention continue the probe into whether J&J's Janssen vaccine increases the likelihood of blood clots in people, especially women, who have taken the shot. At least six cases of problems have been reported to the CDC, including the death of a 45-year-old Virginia woman who died of a stroke shortly after getting vaccinated.
