Juli A. Mazi, a homeopathic doctor in Napa, was arrested for reportedly selling pellets that would supposedly provide "lifelong immunity to COVID-19." She would also provide customers with fake vaccine cards and instructed them how to falsify the information.
According to the San Francisco Chronicle:
Federal authorities said Mazi is the first to face criminal charges related to fake COVID-19 vaccination cards and what are known as homeoprophylaxis immunizations. She’s facing charges of wire fraud and false statements related to health.
