My mom got the vaccine in March. Had a test Monday to check heart. Her heart now has decreased function. Yesterday, she was back at the hospital with a blood clot in her wrist from heart test procedure. Found mass in neck. They think that it is due to thyroid. Now, my mom is older but has never drank, smoked, she has lived a clean life. I don't know for sure if new health issues are from the vaccine, but I am suspicious.
