Inactivated rotavirus vaccine by parenteral administration induces mucosal immunity in mice

Parenteral immunization of mice with a genetically inactivated pertussis toxin DNA vaccine induces cell-mediated immunity and protection.

The immunogenicity and protective efficacy of a DNA vaccine encoding a genetically inactivated S1 domain of pertussis toxin was evaluated using a murine respiratory challenge model of Bordetella pertussis infection. It was found that mice immunized via the intramuscular route elicited a purely cell-mediated immune response to the DNA vaccine, with high levels of gamma interferon (IFN-gamma) and...

Mucosal Contact with Live Virus Inactivated Poliovirus Vaccine Is Dependent Induction of Mucosal Immunity by

Inactivated HIV-1-Capturing Nanospheres Induce Mucosal Immunity Following Intravaginal Administration in Mice

A Vault Nanoparticle Vaccine Induces Protective Mucosal Immunity

BACKGROUND Generation of robust cell-mediated immune responses at mucosal surfaces while reducing overall inflammation is a primary goal for vaccination. Here we report the use of a recombinant nanoparticle as a vaccine delivery platform against mucosal infections requiring T cell-mediated immunity for eradication. METHODOLOGY/PRINCIPAL FINDINGS We encapsulated an immunogenic protein, the maj...

Impact of inactivated poliovirus vaccine on mucosal immunity: implications for the polio eradication endgame

The polio eradication endgame aims to bring transmission of all polioviruses to a halt. To achieve this aim, it is essential to block viral replication in individuals via induction of a robust mucosal immune response. Although it has long been recognized that inactivated poliovirus vaccine (IPV) is incapable of inducing a strong mucosal response on its own, it has recently become clear that IPV...
