I am not very happy to have to admit this is very close to truth. My parent is now in the hospital, cardiac issues, he had already cardiac issues but was stable with his pacemaker, until he got the pfizer boostah, he got quickly in trouble. My mother had no history of heart issues, and after her boostah, she is now also having cardiac issues and gets tired very easily. Both still want me to get the clot shot and refuse to acknowledge the shot might be harmful. Bear in mind they both also experienced the induced magnetism with their two Sinovac doses.
