Abstract
Porvac is a classical swine fever (CSF) subunit vaccine. It is safe and induces a robust neutralizing antibody response, sterilizing immunity, and early protection, and it prevents vertical transmission in pregnant sows. The methodology to approve Porvac batches is a challenging experiment in pigs with a virulent CSF virus strain. However, there is an ethical reason to reduce, at minimum, the use of animals in these lethal experiments. The knowledge indicates that neutralizing antibody titers in the blood could be a good correlate of protection. The results of 22 challenge experiments involving 116 Porvac vaccinated and 38 unvaccinated animals were analyzed. All vaccinated animals remained free from CSF clinical signs and pathological lesions and were negative for viral isolation after the challenge.
In contrast, all unvaccinated pigs developed clinical and pathological signs of the disease and had to be euthanized eight days post-challenge. All vaccinated pigs exhibited high neutralizing antibody titers, with a geometric mean value of 1: 5153. The lower titer registered was 1: 800. A complete correspondence between neutralizing antibody titers and protection was demonstrated. These results support substituting the viral challenge test for the neutralizing peroxidase-linked assay in the release of Porvac® batches.

Abstract
The genus Pestivirus of the family Flaviviridae mainly comprises classical swine fever virus (CSFV), bovine viral diarrhea virus 1 (BVDV-1), BVDV-2, border disease virus (BDV), and multiple new pestivirus species such as atypical porcine pestivirus (APPV), giraffe pestivirus, and antelope pestivirus. Pestiviruses cause infectious diseases, resulting in tremendous economic losses to animal husbandry. Different types of pestivirus vaccines have been developed to control and prevent these important animal diseases. In recent years, pestiviruses have shown great potential as viral vectors for developing multivalent vaccines. This review analyzes the advantages and disadvantages of various pestivirus vaccines, including live attenuated pestivirus strains, genetically engineered marker pestiviruses, and pestivirus-based multivalent vaccines. This review provides new insights into the development of novel vaccines against emerging pestiviruses, such as APPV and ovine pestivirus.

Chimeric Antigen by the Fusion of SARS-CoV-2 Receptor Binding Domain with the Extracellular Domain of Human CD154: A Promising Improved Vaccine Candidate. Vaccines (Basel) 2022; 10:897. [PMID: 35746505 PMCID: PMC9228316 DOI: 10.3390/vaccines10060897] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 05/26/2022] [Accepted: 05/27/2022] [Indexed: 02/04/2023] Open
Abstract
COVID-19 is a respiratory viral disease caused by a new coronavirus called SARS-CoV-2. This disease has spread rapidly worldwide with a high rate of morbidity and mortality. The receptor-binding domain (RBD) of protein spike (S) mediates the attachment of the virus to the host's cellular receptor. The RBD domain constitutes a very attractive target for subunit vaccine development due to its ability to induce a neutralizing antibody response against the virus. With the aim of boosting the immunogenicity of RBD, it was fused to the extracellular domain of CD154, an immune system modulator molecule. To obtain the chimeric protein, stable transduction of HEK-293 was carried out with recombinant lentivirus and polyclonal populations and cell clones were obtained. RBD-CD was purified from culture supernatant and further characterized by several techniques. RBD-CD immunogenicity evaluated in mice and non-human primates (NHP) indicated that recombinant protein was able to induce a specific and high IgG response after two doses. NHP sera also neutralize SARS-CoV-2 infection of Vero E6 cells. RBD-CD could improve the current vaccines against COVID-19, based in the enhancement of the host humoral and cellular response. Further experiments are necessary to confirm the utility of RBD-CD as a prophylactic vaccine and/or booster purpose.

Abstract
Classical swine fever is a highly contagious viral disease with a significant impact on food production worldwide. It currently represents one of the main limitations for the development of the pig industry in Cuba. PorvacÒ is a subunit marker vaccine that confers a very rapid onset of protection. Since there are different production systems in pig breeding, readjustments in the vaccination program are often required. This study compares the safety and efficacy in piglets of two vaccination schedules with PorvacÒ (0-2 weeks and 0-3 weeks), initiated at two or three weeks of age. Clinical monitoring was conducted, and a neutralization peroxidase-linked assay was used to measure the neutralization titers. All immunization regimens were safe and well-tolerated, without local or systemic adverse reactions in the vaccinated animals. Geometric mean neutralizing antibody titers higher than 1/1500 were detected in all groups during the six months of the trial. One month after the second immunization, piglets primed at two weeks of age, and boostered three weeks later, developed significantly higher neutralization titers (1/15644) compared to those vaccinated at a similar age but with a two-week interval between doses (1/5760). However, no significant differences in the titers were found three and six months after vaccination among the four regimens. In summary, all the variants studied are effective, but it is recommended to start vaccination at two weeks old, with the second dose at either two or three weeks later, depending on the production system and the purpose of the farm.

Abstract
E2-CD154 subunit vaccine candidate is safe and protects swine from Classical Swine Fever (CSF). However, its safety and immunogenicity in pregnant sows, and the capacity of maternal derived neutralizing antibodies (MDNA) to protect the offspring is yet to be demonstrated. The aim of this study was to evaluate the safety and immunogenicity of E2-CD154 in pregnant sows, and the capacity of MDNA to protect the offspring. Seventeen pregnant sows were vaccinated twice with E2-CD154 in either the first or the second third of pregnancy. Pregnancy and litter parameters were compared with a control group of non-vaccinated sows. Neutralizing antibodies (NAb) were monitored. The time course of MDNA was assessed in a group of six piglets born to an E2-CD154 immunized sow, and the animals were challenged with CSFV at day 63 after birth. No local or systemic adverse effects were found. Neither abortions, nor congenital malformations, nor stillbirths were observed. All sows develop high NAb titers after the first immunization. Piglets born to an E2-CD154 vaccinated sow still showed MDNA titers of 1:100 at day 63 after birth. Five animals were negative for virus isolation after challenge, and showed neither signs of CSF, nor macroscopic lesions in the organs. The other piglet was positive for CSFV isolation, and macroscopic lesions were observed in the spleen, although no clinical signs of CSF other than fever were detected. E2-CD154 vaccine candidate was safe and immunogenic in pregnant sows, and the passive immunity transmitted to the offspring was still protective by day 63 after birth.
