Advances in Vaccine Delivery and Vaccine Administration

Dear Colleagues,

Vaccination is crucial for preventing infections by providing protection against invading pathogens. Recent advancements in vaccine delivery systems, such as lipid nanoparticles and polymeric nanoparticles, have enabled the efficient delivery of mRNA and vaccine antigens, resulting in enhanced vaccine efficacy. It is vital to develop vaccines that can trigger a strong immune response, characterized by both humoral and cell-mediated immunity, long-lasting protection, and immune memory. Vaccine delivery systems not only protect the vaccine cargo but also improve the delivery of vaccine antigens to target cells, thus enhancing vaccine-induced immunity. However, further research is needed to fully utilize these delivery systems for all types of vaccine antigens. Moreover, there is a need for improved vaccine administration systems that are more patient-friendly and cost-effective. Developments in vaccine administration strategies, such as microneedle vaccination, oral vaccination, and intranasal vaccination, have made them more patient-friendly, but the production of such vaccines remains challenging.

This Special Issue will spotlight recent advancements in vaccine delivery methods and innovative vaccine administration systems, providing readers with the most up-to-date research findings in the field of vaccine development.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pharmaceutics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
