My niece flew home from the east coast just over a month ago. She got a booster the day before coming for her new job at a hospital. She set off the metal detector at the airport. Their hand held scanner pinged at injection site on her arm. She said the screener knew and said “Oh hun, you didn’t get the placebo” and waved her through. She stayed at my moms house. Mom had already had some breathing issues, but 1 week later she was in the hospital with SATs so low they had the crash cart waiting beside her. They tested her for everything imaginable and still have not given us a definitive reason for her illness. When I asked about shedding or parasites they all looked at me like I was crazy. In hospital for over a week. She refused Remdisiver thank goodness! They sent her home with no real answers. Someone talked her into Ivermectin. 😉Almost back to 100% She wished she had taken it sooner!!
