Mouse Models of Heterologous Flavivirus Immunity: A Role for Cross-Reactive T Cells [PDF]

open access: yes, 2019
Most of the world is at risk of being infected with a flavivirus such as dengue virus, West Nile virus, yellow fever virus, Japanese encephalitis virus, tick-borne encephalitis virus, and Zika virus, significantly impacting millions of lives. Importantly,

Heterologous prime-boost vaccination with VLA2001 and an ORFV-based vector enhances spike- and nucleocapsid-specific immunity in mice

open access: yesFrontiers in Immunology
Heterologous prime–boost vaccination has emerged as a promising approach to enhance immune responses by combining vaccines with complementary mechanisms of antigen delivery and immune activation.

Perforin and Gamma Interferon Expression Are Required for CD4(+) and CD8(+) T-Cell-Dependent Protective Immunity against a Human Parasite, Trypanosoma cruzi, Elicited by Heterologous Plasmid DNA Prime-Recombinant Adenovirus 5 Boost Vaccination

open access: yes, 2009
A heterologous prime-boost strategy using plasmid DNA, followed by replication-defective recombinant adenovirus 5, is being proposed as a powerful way to elicit CD4(+) and CD8(+) T-cell-mediated protective immunity against intracellular pathogens.

T and B cell responses in different immunization scenarios for COVID-19: a narrative review

open access: yesFrontiers in Immunology
Vaccines against COVID-19 have high efficacy and low rates of adverse events. However, none of the available vaccines provide sterilizing immunity, and reinfections remain possible.

Induction and in Vitro demonstration of cellular immunity to DNA and RNA viruses in guinea-pigs [PDF]

open access: yes, 1975
Guinea-pigs were immunized with different cells infected with vaccinia virus, herpes simplex virus type 1, herpesvirus saimiri, and the virus of vesicular stomatitis. Development of cellular immunity against these viruses was observed with transformation

Studies on heterologous immunity in schistosomiasis. 4. Heterologous schistosome immunity in cattle.

open access: yesBulletin of the World Health Organization, 1970
Previous studies have shown that when mice and monkeys are infected with bovine schistosomes they develop a considerable degree of heterologous immunity against subsequent challenge with Schistosoma mansoni. The present report describes a study on the reverse effect in which calves were first exposed to cercariae of S.

Demonstration of cross-protective vaccine immunity against an emerging pathogenic Ebolavirus Species. [PDF]

open access: yesPLoS Pathogens, 2010
A major challenge in developing vaccines for emerging pathogens is their continued evolution and ability to escape human immunity. Therefore, an important goal of vaccine research is to advance vaccine candidates with sufficient breadth to respond to new

Studies on heterologous immunity in schistosomiasis. I. Heterologous schistosome immunity in mice.

open access: yesBulletin of the World Health Organization, 1968
Epidemiological and experimental studies indicate that heterologous immunity resulting from exposure to bovine and other animal schistosomes might be of some importance in determining the relative severity of schistosome infection in man in different parts of the world.

Immunogenicity of heterologous recombinant adenovirus prime-boost vaccine regimens is enhanced by circumventing vector cross-reactivity

open access: yes, 2006
The high prevalence of preexisting immunity to adenovirus serotype 5 (Ad5) in human populations has led to the development of recombinant adenovirus (rAd) vectors derived from rare Ad serotypes as vaccine candidates for human immunodeficiency virus type ...

Studies on heterologous immunity in schistosomiasis. 5. Heterologous schistosome immunity in sheep.

open access: yesBulletin of the World Health Organization, 1973
Previous studies have shown that when cattle are exposed to cercariae of Schistosoma mansoni they develop considerable resistance to subsequent challenge with S. mattheei. The present study showed that when sheep are immunized with S. mansoni cercariae they too develop a marked resistance to subsequent challenge with S. mattheei.
