Transfer factors that are taken from cows are POSSIBLY SAFE when used short-term, up to 3 months. They can cause fever in some people. Transfer factors given as a shot (by injection) can cause swelling and pain where the injection is given.
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.
Special Precautions & Warnings:Children: The shot form of transfer factor from humans is POSSIBLY SAFE in children when given for up to 6 years. Transfer factor from cows is POSSIBLY SAFE in children when given by mouth for up to 6 months.
Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking transfer factor if you are pregnant or breast-feeding. Stay on the safe side and avoid use.
- 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.
