Not if she signed it of her own volution, willfully showed up at the appointed time, sat down and then let them inject her. As bad as this clown world is, Medical professionals will simply point to Govt/ Health dept policy as a requirement for the operation and unless she was physically dragged there and forcibly jabbed - any suit will go nowhere - unless there was clear overt misconduct outside of the proscribed administration procedure. Unfortunately, no-one should be more concerned with one's health than themself and then is always a risk (incl Death) associated with any medical intervention. RIP, however would this be even a post if her body violently rejected the transplant after a successful operation and she still passed.
