A composition for eliciting a T-cell mediated immune response in a subject
includes transfer factor from at least two different types of source
animals. For example, the composition may include mammalian transfer
factor and nonmammalian transfer factor. An example of the composition
includes a combination of a colostrum-derived product, which includes the
mammalian transfer factor, and an egg-derived product, which includes the
nonmammalian transfer factor. Additionally, the egg-derived product may be
substantially free of fat. Methods for forming the composition and
eliciting T-cell mediated immune responses in subjects that have been
treated with the composition are also disclosed.
