Task: Answer Verification
Input (English): Question: Does influenza vaccination promote cellular or humoral activation among heart transplant recipients?
Answer: Despite the small number of patients in the study, influenza vaccination did not induce undesirable side effects, such as graft rejection or allo-sensitization. Generation of a positive anti-vaccine response was lower among the transplant recipients than healthy volunteers (41% vs. 80%). Clinical efficacy of the vaccine among the responders was not evaluated.
Output (English): no
