There has been good and bad news for 'Bubble baby' Nina Warnell this week.
The good news is that doctors have found a donor match to treat her condition - severe combined immune deficiency syndrome (SCID).
The bad news is that doctors in Poland misdiagnosed the type of SCID, which has more than 30 forms, and the family will now have to wait nine months before the procedure can go ahead.
Doctors at Great Ormond Street Hospital, where Nina was dramatically flown to by medical jet last month, retested her on arrival.
Fourteen-week-old Nina, who has no immune system, will now have to undergo enzyme replacement therapy and will not be able to have the transplant for another 9 months.
Dad Graeme Warnell, 42, who grew up in Braywick Road, Maidenhead, said: "Hopefully Nina can survive on this new treatment and the donor will still be willing to help in nine months."
