Special Issue Information

Dear Colleagues,

We would like to invite you to contribute to the Special Issue (SI) entitled Recent Advances in Vaccine Delivery.

This SI will focus on highlighting innovative recent developments pertaining to vaccine delivery, as discussed below.

Vaccines are delivered to stimulate the body's immune response against specific infectious agents or diseases. Vaccines are typically delivered via oral and parenteral routes of administration. However, it is well known that these routes possess several limitations, and, therefore, alternative routes for vaccine drug delivery, which overcome the limitations of the traditional routes, could be useful. In addition, the production methods and safety of the vaccine, as well as other societal, political and financial issues, determine the success of a vaccine development and delivery programme.

In view of the above, we welcome your research or review papers on one or more of the following topics, in addition to any other that is related to the theme of the SI:

  1. Vaccine production and formulation;
  2. Digitalisation of vaccine production systems;
  3. Design of materials and devices for vaccine delivery;
  4. Methods of targeting sites for vaccine delivery;
  5. Vaccine design; pharmacokinetics, bioavailability and patient safety (clinical and preclinical trials);
  6. Societal, financial, environmental and political issues in vaccine production, delivery and availability;
  7. Use of biomaterials as possible carriers for vaccine delivery; 
  8. Biosafety issues related to vaccine delivery;
  9. Delivery strategies for new vaccine formulations;
  10. Scale up and technology transfer of vaccine formulations for clinical studies;
  11. Regulatory authorisation and commercialisation of vaccines.   

We look forward to your active participation in this endeavour and to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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 100 words) can be sent to the Editorial Office for announcement on this website.

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-blind 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.

Generating long-lived mucosal and systemic antibodies through respiratory immunization with protective antigens encapsulated in nanoscale biodegradable particles could potentially decrease or eliminate the incidence of many infectious diseases, but requires the incorporation of a suitable mucosal immunostimulant. We previously found that respiratory immunization with a model protein antigen (LPS-free OVA) encapsulated in PLGA 50:50 nanoparticles (~380 nm diameter) surface-modified with complement peptide-derived immunostimulant 02 (CPDI-02; formerly EP67) through 2 kDa PEG linkers increases mucosal and systemic OVA-specific memory T-cells with long-lived surface phenotypes in young, naïve female C57BL/6 mice. Here, we determined if respiratory immunization with LPS-free OVA encapsulated in similar PLGA 50:50 microparticles (~1 μm diameter) surface-modified with CPDI-02 (CPDI-02-MP) increases long-term OVA-specific mucosal and systemic antibodies. We found that, compared to MP surface-modified with inactive, scrambled scCPDI-02 (scCPDI-02-MP), intranasal administration of CPDI-02-MP in 50 μL sterile PBS greatly increased titers of short-term (14 days post-immunization) and long-term (90 days post-immunization) antibodies against encapsulated LPS-free OVA in nasal lavage fluids, bronchoalveolar lavage fluids, and sera of young, naïve female C57BL/6 mice with minimal lung inflammation. Thus, surface modification of ~1 μm biodegradable microparticles with CPDI-02 is likely to increase long-term mucosal and systemic antibodies against encapsulated protein antigen after respiratory and possibly other routes of mucosal immunization.

To prevent the coronavirus disease 2019 (COVID-19) pandemic and aid restoration to prepandemic normality, global mass vaccination is urgently needed. Inducing herd immunity through mass vaccination has proven to be a highly effective strategy for preventing the spread of many infectious diseases, which protects the most vulnerable population groups that are unable to develop immunity, such as people with immunodeficiencies or weakened immune systems due to underlying medical or debilitating conditions. In achieving global outreach, the maintenance of the vaccine potency, transportation, and needle waste generation become major issues. Moreover, needle phobia and vaccine hesitancy act as hurdles to successful mass vaccination. The use of dissolvable microneedles for COVID-19 vaccination could act as a major paradigm shift in attaining the desired goal to vaccinate billions in the shortest time possible. In addressing these points, we discuss the potential of the use of dissolvable microneedles for COVID-19 vaccination based on the current literature. Full article
