So very sorry to hear of your father, Firestar! Did his Doctor indicate the possibility that the jabs may have been responsible? I just read this article yesterday of a young man who developed problems after his jab which I found very interesting. There were good comments afterwards from people who had issues as well. My thoughts are with you and I am sincerely sorry to hear of your dad's death.
