Transfer factor factors are contraindicated for women who are pregnant or breastfeeding. When human- and bovine-derived transfer factor are generated from blood cells they carry the potential for blood-borne disease such as HIV/AIDS and Hepatitis C. Colostrum is a form of milk produced by the mammary glands of mammals (including humans) in late pregnancy. Colostrum also contains multiple immune modulating molecules, including high antibody levels. Based on studies noting an overlap in the observed in vitro effects between a molecule contained in colostrum called colostrinin and the dialyzable leukocyte extract mentioned above, a hypothesis formed that the two were the same.

Prenex normal form Prenex normal form A formula of the predicate calculus is in prenex normal form if it is written as a string of quantifiers and bound variables, called the prefix, followed by a quantifier-free part, called the matrix. Every formula in classical logic is equivalent to a formula in prenex normal form. For example, if formula_1, formula_2, and formula_3 are quantifier-free formulas with the free variables shown then is in prenex normal form with matrix formula_5, while is logically equivalent but not in prenex normal form. Every first-order formula is logically equivalent (in classical logic) to some formula in prenex normal
