Abstract

The present invention provides vaccine compositions and methods of producing such compositions. Other embodiments of the invention include methods of treating a pathogen infection, methods of vaccinating a subject against a pathogen infection, and methods for treating an antibiotic-resistance bacterial infection in a subject in need thereof. In further embodiments, the invention includes methods of decreasing the level of a pathogen in a subject having a pathogen infection, methods of increasing the surviving rate of a subject having a pathogen infection, methods of reducing the level of pain associated with a pathogen infection, and methods of reducing the level of distress associated with a pathogen infection in a subject in need thereof. Novel scaffold compositions and opsonin-bound or lectin-bound pathogen compositions, and uses thereof, are also provided herein.
