Abstract

Since its introduction, vaccination has improved health outcomes tremendously. However, modern vaccination efforts are still difficult to implement, particularly in developing countries with warm climates. This includes complex and expensive cold-chain management of vaccines to maintain stability, a lack of medical personnel to administer parental vaccines, and needle phobia. As an alternative, dissolvable microneedles have recently been studied for their simple and painless application. In this thesis, I present a novel manufacturing process for polymer-based dissolvable microneedles, loaded with virus-like particles vaccines conjugated to TRIO or Sialokinin peptides to target malaria and arboviruses, respectively. We have performed multiple characterization studies to assess needle sharpness, integrity, and skin insertion force. We have also evaluated the thermostability properties of the microneedles containing vaccines after storing them at elevated temperature conditions for five months. Finally, the immunogenicity of these vaccines was evaluated in mice after transdermal (microneedle) and intramuscular (hypodermic needle) administration.
