Abstract
A method of passively immunizing a mammal against a condition caused by an antigen comprising: administering to the mammal immunizing amounts of an antibody obtained from a domesticated fowl which has been immunized against the antigen; the mammal being tolerant to the antibody by virtue of having a history of consumption of antibody containing material derived from the egg of a fowl.

- and
- (b) administering to said mammal an immunologically effective amount of an antibody obtained from a domesticated fowl immunized against said antigen.
