We have a relative in her late 60s whose had extensive cardic issues resulting from a blood cancer. Without going into too much detail her docs want her to wait on vax for now. (Long story that has multiple layers as to why)

Having said that IF she gets covid and presents symptoms would these infusions be a good first step for her? We are trying to do some research and not familiar with this other than googling.

Is this similar to the vaccine or something completely different?

Thank you for any input

Also, I'd recommend calling Urgent Cares or your primary care physician to have a place in mind to get it in case she gets COVID-19. Always better to be prepared. I know someone that had a whale of a time finding a place, and lost a day or two in the search. The antibody treatments work better the earlier they are used.
