Abstract
Compositions and methods are described in which the topical application of a toll-like receptor 7 agonist or a toll-like receptor 9 agonist at or near a subdermal vaccination site provides an enhanced response to the vaccination. The enhanced response can be an elevated antibody titer relative to an untreated but vaccinated subject, and/or development of cross-species immunity to species not present in the vaccinating composition.
