My father died in March of 2021, of heart failure. He had quaddrople bypass surgery over 15 years ago, pacemaker for 5-6 years. After he came back positive on the Covid19 test the doctor gave him a prescription of Ivermectin 3X per day for 3 days. By 4th day all the symptoms were gone.
He also suffered from Pick’s disease for past 9 years. It had affected his motor control, balance, speech.
I am sorry for your loss. I am glad he recovered from covid. A series of 1 even if the ivermectin helped, which is not proven, proves nothing.
