- Dosing considerations for Transfer Factor.
There is some concern about the possibility of catching "mad cow disease" (bovine spongiform encephalitis, BSE) or other diseases from products that come from animals. "Mad cow disease" has not been transmitted by transfer factor, but it is probably wise to avoid animal products from countries where mad cow disease has been found.
Do not take transfer factor if:
- You are pregnant or breast-feeding.
- For preventing shingles (varicella zoster infection) in children with leukemia: a single dose of transfer factor (from humans) that is specific for the varicella virus is given. The health provider giving the shot calculates the proper dose based on the child's weight.
