Abstract
As emerging and re-emerging pathogens, filoviruses, especially Ebola virus (EBOV), pose a great threat to public health and require sustained attention and ongoing surveillance. More vaccines and antiviral drugs are imperative to be developed and stockpiled to respond to unpredictable outbreaks. Virus-like vesicles, generated by alphavirus replicons expressing homogeneous or heterogeneous glycoproteins (GPs), have demonstrated the capacity of self-propagation and shown great potential in vaccine development. Here, we describe a novel class of EBOV-like vesicles (eVLVs) incorporating both EBOV GP and VP40. The eVLVs exhibited similar antigenicity as EBOV. In murine models, eVLVs were highly attenuated and elicited robust GP-specific antibodies with neutralizing activities. Importantly, a single dose of eVLVs conferred complete protection in a surrogate EBOV lethal mouse model. Furthermore, our VLVs strategy was also successfully applied to Marburg virus (MARV), the representative member of the genus Marburgvirus. Taken together, our findings indicate the feasibility of an alphavirus-derived VLVs strategy in combating infection of filoviruses represented by EBOV and MARV, which provides further evidence of the potential of this platform for universal live-attenuated vaccine development.

Abstract
Coronaviruses (CoVs) have the largest genome among RNA viruses and store large amounts of information without genome integration as they replicate in the cell cytoplasm. The replication of the virus is a continuous process, whereas the transcription of the subgenomic mRNAs is a discontinuous one, involving a template switch, which resembles a high frequency recombination mechanism that may favor virus genome variability. The origin of the three deadly human CoVs SARS-CoV, MERS-CoV and SARS-CoV-2 are zoonotic events. SARS-CoV-2 has incorporated in its spike protein a furine proteolytic site that facilitates the activation of the virus in any tissue, making this CoV strain highly polytropic and pathogenic. Using MERS-CoV as a model, a propagation-deficient RNA replicon was generated by removing E protein gene (essential for viral morphogenesis and involved in virulence), and accessory genes 3, 4a, 4b and 5 (responsible for antagonism of the innate immune response) to attenuate the virus: MERS-CoV-Δ[3,4a,4b,5,E]. This RNA replicon is strongly attenuated and elicits sterilizing protection after a single immunization in transgenic mice with the receptor for MERS-CoV, making it a promising vaccine candidate for this virus and an interesting platform for vector-based vaccine development. A strategy could be developed for the design of RNA replicon vaccines for other human pathogenic coronaviruses.

Abstract
Self-amplifying RNA replicons are promising platforms for vaccine generation. Their defects in one or more essential functions for viral replication, particle assembly, or dissemination make them highly safe as vaccines. We previously showed that the deletion of the envelope (E) gene from the Middle East respiratory syndrome coronavirus (MERS-CoV) produces a replication-competent propagation-defective RNA replicon (MERS-CoV-ΔE). Evaluation of this replicon in mice expressing human dipeptidyl peptidase 4, the virus receptor, showed that the single deletion of the E gene generated an attenuated mutant. The combined deletion of the E gene with accessory open reading frames (ORFs) 3, 4a, 4b, and 5 resulted in a highly attenuated propagation-defective RNA replicon (MERS-CoV-Δ[3,4a,4b,5,E]). This RNA replicon induced sterilizing immunity in mice after challenge with a lethal dose of a virulent MERS-CoV, as no histopathological damage or infectious virus was detected in the lungs of challenged mice. The four mutants lacking the E gene were genetically stable, did not recombine with the E gene provided in trans during their passage in cell culture, and showed a propagation-defective phenotype in vivo. In addition, immunization with MERS-CoV-Δ[3,4a,4b,5,E] induced significant levels of neutralizing antibodies, indicating that MERS-CoV RNA replicons are highly safe and promising vaccine candidates.

Abstract
BACKGROUND Live attenuated vaccines (LAVs) can mimic natural infection and have advantages to stimulate a robust and sustained immune response as well as to confer long-term protection. However, safety concerns is one of the major obstacles for LAVs development. In an effort to achieve the optimal balance between immunogenicity and safety, researchers currently have taken different strategies for the development of LAVs. METHODS We constructed a novel infectious self-propagating hybrid replicon particle (PRP), VEEV-RABV-G, through replacing the entire structural proteins of the Venezuelan equine encephalitis virus (VEEV) with the glycoprotein of rabies virus (RABV-G) as the single structural protein. We evaluated the potential of VEEV-RABV-G as a safe live attenuated vaccine in mice model. FINDINGS We found that VEEV-RABV-G could self-propagate efficiently in cell culture and induce a robust humoral immunity and provide protection against virulent RABV challenge in immunized mice. Remarkably, VEEV-RABV-G is highly attenuated in both adult and sucking mice, causing much weaker inflammatory and apoptotic effects in the brains of infected adult mice and significantly lower weight loss and morbidity compared with the commonly used RABV-derived LAVs. INTERPRETATION This study reveals the feasibility of developing novel rabies vaccines based on the self-replicating PRPs.

Abstract
PURPOSE OF REVIEW To briefly describe some of the replication-competent vectors being investigated for development of candidate HIV vaccines focusing primarily on technologies that have advanced to testing in macaques or have entered clinical trials. RECENT FINDINGS Replication-competent viral vectors have advanced to the stage at which decisions can be made regarding the future development of HIV vaccines. The viruses being used as replication-competent vector platforms vary considerably, and their unique attributes make it possible to test multiple vaccine design concepts and also mimic various aspects of an HIV infection. Replication-competent viral vectors encoding simian immunodeficiency virus or HIV proteins can be used to safely immunize macaques, and in some cases, there is evidence of significant vaccine efficacy in challenge protection studies. Several live HIV vaccine vectors are in clinical trials to evaluate immunogenicity, safety, the effect of mucosal delivery, and potential effects of preexisting immunity. SUMMARY A variety of DNA and RNA viruses are being used to develop replication-competent viral vectors for HIV vaccine delivery. Multiple viral vector platforms have proven to be well tolerated and immunogenic with evidence of efficacy in macaques. Some of the more advanced HIV vaccine prototypes based on vesicular stomatitis virus, vaccinia virus, measles virus, and Sendai virus are in clinical trials.
