Special Issue Information

Dear Colleagues,

Scientists have attempted to use different kinds of novel technologies in animal vaccine development. Since the regulatory requirements of clinical trials for animal products are shorter than those in human vaccines, novel technologies are easier to commercialize in animal vaccine products. Many bacterial and eukaryotic cell-expressed recombinant proteins and viral vectors have been used for decades, and many kinds of immune potentiating materials, such as peptides, proteins, polymers, and emulsified oils, have been used in adjuvants. Biosafety and high immunization efficacy are the basic requirements of a vaccine. However, easily immunizing operations and low manufacturing costs are also essential for a successful animal vaccine product. This Special Issue will not only include novel antigen or adjuvant design but also cover large-scale production and manufacturing improvement technologies.

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. Vaccines 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 2700 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.

Background/Objectives: Porcine reproductive and respiratory syndrome virus (PRRSV) remains one of the most economically significant pathogens in the global swine industry. Despite the availability of commercial vaccines for over three decades, they fail to induce sterile immunity and often provide inconsistent protection against heterologous PRRSV strains. This study aimed to predict vaccine immunogenicity by detecting strain-specific immune responses that related to an immune correlate of protection (CoP) against different PRRSV-2 strains. Methods: Post-weaning pigs were vaccinated with five commercially available PRRSV-2 vaccines or received sterile PBS injection as a control. At 28 days post-vaccination (dpv), all pigs were humanely euthanized for large-volume blood collection to isolate peripheral blood mononuclear cells (PBMCs) and plasma, establishing the immune bank. PBMCs and plasma from each group were then tested against six PRRSV-2 strains to evaluate immune responses. In addition, T cell epitope coverage between vaccine and field PRRSV-2 strains was assessed using the EpiCC (in silico) tool to enhance predictive capacity. Results: While neutralizing antibodies were undetectable in all vaccinated pigs at 28 dpv, PRRSV-specific IFNγ–producing cells were detected at various levels in each vaccinated group following restimulation with different PRRSV-2 strains. Additionally, a positive correlation was observed for the EpiCC coverage of the N gene and mean IFNγ responses to VR2332 (SLA class I and II) and NC24-6 (SLA class II). Conclusions: The PRRSV immune bank demonstrated potential as a tool for predicting vaccine immunogenicity against different PRRSV-2 strains and EpiCC provides additional information on T cell epitope cross conservation. The combined approach may provide a valuable framework for selecting PRRSV vaccines for more effective prevention and control in endemic areas. Full article

Abstract
Background/Objectives: A new multivalent vaccine (DIVENCE® PENTA), containing Bovine viral diarrhoea virus (BVDV) types 1 and 2 recombinant proteins, live gE/tk double gene deleted Bovine Herpesvirus type 1 (BoHV-1 or IBR), live attenuated Bovine respiratory syncytial virus (BRSV) and inactivated parainfluenza-3 [...] Read more.
Background/Objectives: A new multivalent vaccine (DIVENCE® PENTA), containing Bovine viral diarrhoea virus (BVDV) types 1 and 2 recombinant proteins, live gE/tk double gene deleted Bovine Herpesvirus type 1 (BoHV-1 or IBR), live attenuated Bovine respiratory syncytial virus (BRSV) and inactivated parainfluenza-3 virus (PI-3) has been designed to protect cattle against the main viral pathogens associated with Bovine respiratory disease (BRD). The aim of this study was to demonstrate the efficacy of DIVENCE® PENTA against experimental infections with BVDV-1, BVDV-2, IBR, BRSV and PI-3 in young calves. Methods: Ten-week-old calves were given two intramuscular doses three weeks apart. The efficacy was evaluated by means of an experimental challenge three weeks after vaccination. Serology, clinical signs, rectal temperature, white blood cell count, viral shedding and lung lesions were monitored after the challenge. Results/Conclusions: The results demonstrated a significant sparing of BRD in calves vaccinated with DIVENCE® PENTA, as evidenced by fewer clinical signs, lower rectal temperatures, reduced viral shedding and less severe pulmonary lesions compared to control animals. A significant reduction in hyperthermia, leukopenia and viraemia post-challenge was also observed, highlighting the efficacy of the multivalent vaccine against BVDV types 1 and 2, IBR, BRSV and PI-3 in young calves.
