SGT Johnson is NOT half FLOOD, he is full human, If you have read any of the Halo books, you find out that Johnson had contracted a disease that he was cured for, and this changed his bodys emune system. And so when the flood tryed to take over his body, his emune system rejected the flood, ( I may be a lil sketchy on full detale as i have not read the books in a while).
Please feel free to add anything i have missed.
Cheers.
