Influenza A virus remains a major threat to public health, and the inactivated split-virus vaccine is the most prevalent vaccine used worldwide. However, our knowledge about cellular immune responses to the inactivated influenza virus vaccine and its correlation with humoral responses are yet limited, which has restricted our understanding of the vaccine’s protective mechanisms. Herein, in two clinical...
Porcine circovirus type 2 (PCV2) is the main pathogen of porcine circovirus associated disease (PCVAD), causing great economic losses in pig industry. In previous study, we constructed adenovirus vector vaccines expressing PCV2 Cap either modified with Intron A and WPRE, or CD40L and GMCSF, and evaluated all of these vaccines in mice and in pigs. Although Ad-A-C-W and Ad-CD40L-Cap-GMCSF could induce...
To evaluate the cost-effectiveness of adding 23-valent pneumococcal polysaccharide vaccine (PPSV23) to the immunization schedule for the elderly population (age>60years) in Shanghai, China.A decision-tree model, with data and assumptions adapted from the societal perspective of Shanghai City, was developed to project the health outcomes of PPSV23 vaccination (compared with no vaccination) over...
One of the distinct features of the emerging Chinese pseudorabies virus (PRV) variant is its ability to cause severe neurological signs and high mortality in growing pigs in Bartha-K61-vaccinated pig farms. Either single- or multiple-gene-deleted live vaccine candidates have been developed; however, none was evaluated thoroughly in growing pigs. Here, we generated rSMXΔgI/gEΔTK, an attenuated PRV...
Bordetella bronchiseptica is a Gram-negative respiratory pathogen that causes substantial disease in a variety of animals. Filamentous hemagglutinin (FHA) and pertactin are important attachment factors and protective immunogens, which serve as protective antigens in several animal models of infection with B. bronchiseptica. Here, we showed the efficacy of subcutaneous immunization of mice with a recombinant...
The bivalent genetic engineering vaccine of Japanese encephalitis (JE) and Aujeszkj disease (AD) was developed to provide a novel approach to prevent and control these two diseases. NS1 gene of Japanese encephalitis virus (JEV) SA14-14-2 strain was produced by reverse transcriptase-mediated PCR (RT-PCR) and was cloned into vector pUSK to form recombinant plasmid (designed as pUSK-NS1). A co-transfection...
Glycoprotein gene gB, gC and gD of pseudorabies virus (PrV) strain Ea, which was isolated locally in Wuhan, were cloned from the viral genome DNA and expressed in vitro controlled by the major immediately-early promotor/enhancer of HCMV. In the presented paper, Balb/c mice, rabbits and piglets were vaccinated intramuscularly two times at 2-week interval with those eukaryotic expression plasmid pcDB,...
