Preclinical study of influenza bivalent vaccine delivered with a two compartmental microneedle array

Multiple vaccines can be mixed into a single combination to be a single product. However, combination vaccines have problems of complexity. In this study, microneedles were utilized in a compartmental microneedle array (CMA) to deliver two influenza vaccine strains without mixing. In this study, the CMA had two compartments, and two rectangular structures were attached to each end of the array to enable integration of the compartments with the...
