Abstract
Recently, herpesvirus viral vectors that stimulate strong humoral and cellular immunity have been demonstrated to be the most promising platforms for the development of multivalent vaccines, because they contain various nonessential genes and exhibit long-life latency characteristics. Previously, we showed that the feline herpesvirus-1 (FHV-1) mutant WH2020-ΔTK/gI/gE, which was safe for felines and provided efficacious protection against FHV-1 challenge, can be used as a vaccine vector. Moreover, previous studies have shown that the major neutralizing epitope VP2 protein of feline parvovirus (FPV) can elicit high levels of neutralizing antibodies. Therefore, to develop a bivalent vaccine against FPV and FHV-1, we first generated a novel recombinant virus by CRISPR/Cas9-mediated homologous recombination, WH2020-ΔTK/gI/gE-VP2, which expresses the VP2 protein of FPV. The growth characteristics of WH2020-ΔTK/gI/gE-VP2 were similar to those of WH2020-ΔTK/gI/gE, and WH2020-ΔTK/gI/gE-VP2 was stable for at least 30 generations in CRFK cells. As expected, we found that the felines immunized with WH2020-ΔTK/gI/gE-VP2 produced FPV-neutralizing antibody titers (27.5) above the positive cutoff (26) on day 14 after single inoculation. More importantly, recombinant WH2020-ΔTK/gI/gE-VP2 exhibited severely impaired pathogenicity in inoculated and cohabiting cats. The kittens immunized with WH2020-ΔTK/gI/gE and WH2020-ΔTK/gI/gE-VP2 produced similar levels of FHV-specific antibodies and IFN-β. Furthermore, felines immunized with WH2020-ΔTK/gI/gE-VP2 were protected against challenge with FPV and FHV-1. These data showed that WH2020-ΔTK/gI/gE-VP2 appears to be a potentially safe, effective, and economical bivalent vaccine against FPV and FHV-1 and that WH2020-ΔTK/gI/gE can be used as a viral vector to develop feline multivalent vaccines.

Abstract
Senecavirus A (SVA)-associated porcine idiopathic vesicular disease (PIVD) and Pseudorabies (PR) are highly contagious swine disease that pose a significant threat to the global pig industry. In the absence of an effective commercial vaccine, outbreaks caused by SVA have occurred in many parts of the world. In this study, the PRV variant strain PRV-XJ was used as the parental strain to construct a recombinant PRV strain with the TK/gE/gI proteins deletion and the VP3 protein co-expression, named rPRV-XJ-ΔTK/gE/gI-VP3. The results revealed that PRV is a suitable viral live vector for VP3 protein expressing. As a vaccine, rPRV-XJ-ΔTK/gE/gI-VP3 is safe for mice, vaccination with it did not cause any clinical symptoms of PRV. Intranasal immunization with rPRV-XJ-ΔTK/gE/gI-VP3 induced strong cellular immune response and high levels of specific antibody against VP3 and gB and neutralizing antibodies against both PRV and SVA in mice. It provided 100% protection to mice against the challenge of virulent strain PRV-XJ, and alleviated the pathological lesion of heart and liver tissue in SVA infected mice. rPRV-XJ-ΔTK/gE/gI-VP3 appears to be a promising vaccine candidate against PRV and SVA for the control of the PRV variant and SVA.

Abstract
Porcine circovirus-associated diseases (PCVADs) and pseudorabies (PR) are highly contagious and economically significant diseases of swine in China. Porcine circovirus type 3 (PCV3) is an emerging swine pathogen of PCVAD. Currently, no PCV3 vaccine is commercially available, and the epidemic caused by it is still spreading worldwide. In this study, we used the PRV variant strain HNX as the parental virus to construct recombinant PRV with TK/gE gene deletion and capsid (Cap) protein co-expression, named HNX-ΔTK/ΔgE-ORF2. The results revealed that PCV3 Cap protein can be detected in HNX-ΔTK/ΔgE-ORF2-infected PK-15 cells by both western blotting and immunofluorescence assays. Vaccination with HNX-ΔTK/ΔgE-ORF2 did not cause pruritus, ruffled fur, systemic infection, or inflammation (without high expression of interleukin-6 (IL-6) and granulocyte colony-stimulating factor (G-CSF) in plasma). Furthermore, HNX-ΔTK/ΔgE-ORF2 immunization induced an anti-Cap specific antibody, activated a PRV-specific cellular immune response, and provided 100 % protection to mice against the challenge of the virulent HNX strain. Thus, HNX-ΔTK/ΔgE-ORF2 appears to be a promising vaccine candidate against PRV and PCV3 for the control of the PRV variant and PCV3.

Abstract
Herpesvirus based multivalent vaccines have been extensively studied, whereas few of them have been successfully used in clinic and animal husbandry industry due to the low expression of foreign immunogens in herpesvirus. In this study, we developed a new strategy to construct herpesvirus based bivalent vaccine with high-level expression of foreign immunogen, by which the ORF2 gene encoding the major antigen protein Cap of porcine circovirus type 2 (PCV2), was highly expressed in pseudorabies virus (PRV). To obtain the high expression of PCV2 immunogen, tandem repeats of PCV2 ORF2 gene were firstly linked by protein quantitation ratioing (PQR) linker to reach equal expression of each ORF2 gene. Then, the multiple copies of ORF2 gene were respectively inserted into the gE and gG sites of PRV using CRISPR/Cas9 system, in which the expression of ORF2 gene was driven by endogenous strong promoters of PRV. Through this way, the highest yield of Cap protein was achieved in two copies of quadruple ORF2 gene insertion. Finally, in mice and pigs immunized with the bivalent vaccine candidate, we detected high titer of specific antibodies for PRV and neutralized antibodies for PCV2, and observed protective effect of the bivalent vaccine candidate against PRV challenge in immunized pigs, suggesting a potential clinical application of the bivalent vaccine candidate we constructed. Together, our strategy could be extensively applied to the generation of other multivalent vaccines, and will pave the way to construct herpesvirus based multivalent vaccines to effectively reduce the cost of vaccine.

Abstract
Hand, foot, and mouth disease (HFMD) recently emerged as a global public threat. The licensure of inactivated enterovirus A71 (EV-A71) vaccine was the first step in using a vaccine to control HFMD. New challenges arise from changes in the pathogen spectrum while vaccines directed against other common serotypes are in the preclinical stage. The mission of a broad-spectrum prevention strategy clearly favors multivalent vaccines. The development of multivalent vaccines was attempted via the simple combination of potent monovalent vaccines or the construction of chimeric vaccines comprised of epitopes derived from different virus serotypes. The present review summarizes recent advances in HFMD vaccine development and discusses the next steps toward a safe and effective HFMD vaccine that is capable of establishing a cross-protective antibody response.

Abstract
Multivalent DNA vaccines that are delivered by electroporation (EP) through muscle tissue provide a novel method for eliciting immunity against tuberculosis (TB) as well as a broad range of diseases including HIV and cancers. Proper plasmid construction containing suitable protective TB antigens capable of evoking desired vaccine-induced responses would lead to the appropriate induction of both humoral and cellular immunity. DNA vaccines are safe and of low cost in comparison to traditional vaccines while also providing potentially effective prophylactic or therapeutic modalities against currently untreatable diseases. Here, we describe the steps for developing a rational multivalent TB DNA vaccine delivered with intramuscular EP in mice.
