Ryan and Keri Topperwien are playing a waiting game.
The Hamilton couple have watched their 2-year-old son Chace endure months of chemotherapy and a stem cell transplant in a battle against a rare and aggressive form of leukaemia.
Now his parents have to be patient, hoping that Chace’s little body accepts transplanted cord blood, that his bone marrow continues to grow again and that he does not relapse.
“He’s got heaps of fight left in him,” Mr Topperwien said. “He’s nowhere near giving up.”
Days before his second birthday in March this year Chace was diagnosed with the M7 strand of acute myeloid leukaemia, but doctors do not believe the cancer is linked to the immunisation mix-up.
Since the diagnosis Chace has suffered through several rounds of intensive chemotherapy at Auckland’s Starship hospital.
A final conditioning round of chemotherapy readied Chace’s body for the cord blood transplant last month but the Topperwiens, both 27, were unprepared for how severe the side-effects would be.
