I am wondering if this would be a problem in Thalassemia too , because of iron overload.
The medical profession admits their vaccine lab technician died from the work he was doing because of his unrecognised iron overload / hemochromatosis. The elevated iron in his body was accessible to the weakened virus, which is why they've said , 'do not to give this plague vaccine to someone with iron overload'. It was the plague , so it killed him , but what about other vaccines too?

"should not be exposed to live-attenuated plague vaccines"
http://www.ncbi.nlm.nih.gov/pubmed/22896664 Would other live-attenuated virus' also cause problems giving everyone with iron excess , herpes , that you can't get rid of , again , because of the elevated iron?
