Please have them discuss this fully with their treating physician. However it appears the patient has gone from the viral growth phase into the immunological phase of the Covid infection spectrum. The immunological phase is where the patients start developing multi system failure. Now is when the leronlimab should be given for this patient. The immune system needs to be modulated back toward normalcy so it won't damage the organs- which is what Leronlimab does. It would possibly be a wrong idea to give him his second vaccine now as his immune system does not need any more stimulation as it appears to be overdriven currently.
I know of no studies to support or deny this idea of concurrent vaccinations perhaps helping somebody in the immunological phase of a Covid infection.
I hope he survives.
Again, have them discuss this fully with the treating physician for his/her all important input and decision making.
