I'm trying to save my husband's life! Please, help me. What can be done to keep my husband from being put on a ventilator? - If I have T-cells in my body after recovering from COVID, is there any chance of me unknowingly being a carrier of COVID and giving it to my unvaccinated elderly parents? - I heard Dr. McCullough say that once you've had Covid19, you cannot get it again. Does that include all variants, ie, Delta?
