Intranasal vaccination using influenza vectors is a promising approach to developing vaccines against respiratory pathogens due the activation of mucosa-associated immune response. However, there no clear evidence vector design that could be considered preferable. To find optimal structure an with modified NS genomic segment, we constructed four expressing identical transgene sequences inherite...

DNA immunization, although attractive, is poor for inducing mucosal immunity, thus limiting its protective value against most infectious agents. To surmount this shortcoming, we devised a method for mucosal transgene vaccination by using an M cell ligand to direct the DNA vaccine to mucosal inductive tissues and the respiratory epithelium. This ligand, reovirus protein final sigma1, when conjug...

Bovine respiratory syncytial virus (BRSV) is a respiratory pathogen of cattle that causes severe disease in calves alone and as one of several viruses and bacteria that cause bovine respiratory disease complex. Like human RSV this virus modulates the immune response to avoid stimulation of a vibrant CD8+ T cytotoxic cell response and instead promotes a Th2 response. The Th2 skew sometimes resul...

Francisella tularensis is a gram-negative intracellular bacterium that is considered to be a potential category A biological weapon due to its extreme virulence. Although vaccination with the attenuated live vaccine strain (LVS) of F. tularensis can protect against lethal challenge, use of inactivated or subunit forms as vaccine candidates for induction of protective antibody responses has not ...

Despite the progress made by modern medicine, infectious diseases remain one of the most important threats to human health. Vaccination against pathogens is one of the primary methods used to prevent and treat infectious diseases that cause illness and death. Vaccines administered by the mucosal route are potentially a promising strategy to combat infectious diseases since mucosal surfaces are ...

From 2013 an annual nasal live-attenuated influenza vaccine (LAIV—Fluenz) is available for all children in the UK aged 2 and 3 years and other ‘at-risk’ children, as part of the National Health Service (NHS) childhood vaccination programme. 2 The vaccine contains reassortant influenza viruses; two influenza A viruses (H1N1 and H3N2) and one influenza B virus, and has previously been used in chi...

Immunization with Pseudomonas lipopolysaccharide induced both cellular and humoral immunity in rabbits, particularly in the respiratory tract after intranasal immunization. Either parenteral (i.m.) or intranasal immunization elicited an IgG antibody response in respiratory secretions, but only intranasal immunization produced secretory IgA antibody. Immunization by both routes stimulated serum ...

The aim of this study was to evaluate the immune responses to intranasal and intrapulmonary vaccinations with the attenuated Mycoplasma hyopneumoniae (Mhp) 168 strain in the local respiratory tract in pigs. Twenty-four pigs were randomly divided into 4 groups: an intranasal immunization group, an intrapulmonary immunization group, an intramuscular immunization group and a control group. The lev...
