Key Points

To present a conceptual framework for a non-invasive oral strategy to deliver pentavalent vaccines more effectively in children.
Developed a liquid oral syrup stabilized by a pH-responsive polymeric matrix.
Incorporated acid-resistant Eudragit L 100 and mucoadhesive chitosan nanoparticles.
Focused on preserving antigenic integrity against gastric digestion.
Ensured targeted delivery to intestinal Peyer's patches.

Supports the goal of achieving universal health equity in pediatric immunization.

Abstract

Abstract Global paediatric immunization coverage for the pentavalent vaccine (Diphtheria , Tetanus, Pertussis, Hepatitis -B, Haemophilus influenzaetype-b type-b) has compounded by the physiological “injection burden” and magnified by the logistical constraints of parental administration. This perspective explores the transformative potential of a liquid oral syrup stabilized by a pH – responsive polymeric matrix. By involving an acid resistant shield of Eudragit L 100 with mucoadhesive chitosan nanoparticles, we propose a mechanistic framework to preserve antigenic integrity against gastric proteolysis while ensuring targeted delivery to the intestinal Paeyer’s patches. We argue that transitioning to a non- invasive, oral – route delivery system is a critical evolution required to achieve Universal health equity and overcome vaccine hesitancy in the health care system(CDC,2025 )
