From WISH, "New study finds organ recipients rejecting transplant after receiving COVID vaccine":

ACCORDING TO A NEW STUDY PUBLISHED IN THE JOURNAL OF CLINICAL MEDICINE, ACUTE CORNEAL ALLOGRAFTS ARE BEING REJECTED BY IMMUNIZED PATIENTS WHO'VE UNDERGONE THE PROCEDURE. RESEARCHERS SAY THE UNDERLYING CAUSE COULD BE TIED TO A SYSTEMIC INFLAMMATORY RESPONSE ELICITED BY THE SHOT POST-JAB.

THE CORNEA IS THE OUTERMOST LAYER OF A PERSON'S EYE. CORNEAL GRAFTS ARE USED TO RESTORE A DAMAGED CORNEA. THE SURGERY IS KNOWN TO BE ONE OF THE MOST SUCCESSFUL ORGAN TRANSPLANT PROCEDURES WITH LOW REJECTION RATES. IT RESTORES VISION, REDUCES EYE PAIN AND IMPROVES THE APPEARANCE OF THE DISEASED CORNEA.

JAPANESE RESEARCHERS COMPILED DATA FROM 23 STUDIES. A TOTAL OF 23 EYES FROM 21 PATIENTS WHO HAD UNDERGONE CORNEAL GRAFT PROCEDURES WERE ASSESSED. GRAFT REJECTION OCCURRED ANYWHERE FROM ONE DAY TO SIX WEEKS AFTER VACCINATION IN ALL PATIENTS–SOME WHO UNDERWENT THE PROCEDURE AS FAR BACK AS TWENTY YEARS AGO.

Just to be clear, two people mentioned in the study had their corneal transplant rejected post-covid vaccine despite having had the surgery more than 20 years ago.
