Microneedle-Mediated Vaccination: Innovation and Translation

Tao Sheng et al. Adv Drug Deliv Rev. 2021 Dec.

Abstract

Vaccine administration by subcutaneous or intramuscular injection is the most commonly prescribed route for inoculation, however, it is often associated with some deficiencies such as low compliance, high professionalism, and risk of infection. Therefore, the application of microneedles for vaccine delivery has gained widespread interests in the past few years due to its high compliance, minimal invasiveness, and convenience. This review focuses on recent advances in the development and application of microneedles for vaccination based on different delivery strategies, and introduces the current status of microneedle-mediated vaccination in clinical translation. The prospects for its application including opportunities and challenges are further discussed.

Keywords: Drug delivery; Immunology; Microneedle; Transdermal delivery; Vaccination.
