ABSTRACT:
The present invention relates to a method of inducing a Th1-like response against a pathogen in a neonatal host, which comprises administering to the neonatal host an effective amount of IL-12 and an antigen of the pathogen. Also encompassed by the present invention is a method of overcoming suppression of interferon-.gamma. (IFN-.gamma.) expression in a neonatal host due to exposure of the neonatal host to a pathogen or an antigen, which comprises administering to the neonatal host an effective amount of IL-12 and the antigen. The present invention also relates to a method of enhancing the cytokine expression against or in response to a pathogen in a neonatal host, which comprises administering to the neonatal host an effective amount of IL-12 and an antigen of the pathogen.
