Cancer vaccine regimens use various strategies to enhance immune responses to specific tumor-associated antigens (TAAs), including the increasing use of recombinant poxviruses [vaccinia (rV) and fowlpox (rF)] for delivery of the TAA to the immune system. However, the use of replication competent vectors with the potential of adverse reactions have made attenuation a priority for next-generation...
Malaria remains a significant global health burden and a vaccine would make a substantial contribution to malaria control. Chimpanzee Adenovirus 63 Modified Vaccinia Ankara Multiple epitope thrombospondin adhesion protein (ME-TRAP) and vaccination has shown significant efficacy against malaria sporozoite challenge in malaria-naive European volunteers and against malaria infection in Kenyan adul...
Influenza remains an important cause of illness and death in this country. Even though we have safe and effective vaccines, vaccination rates among the elderly and other high-risk groups remain static and well below national goals. Health care providers can boost these vaccination rates by educating themselves, by recommending that their patients be vaccinated, and by implementing evidence-base...
BACKGROUND Schistosomiasis japonica is a zoonotic parasitic disease; developing transmission blocking veterinary vaccines are urgently needed for the prevention and control of schistosomiasis in China. Heterologous prime-boost strategy, a novel vaccination approach, is more effective in enhancing vaccine efficacy against multiple pathogens. In the present study, we established a novel heterolog...
The ability of heterologous prime-boost vaccination to elicit robust CD8+ T cell responses has been well documented. In contrast, relatively little is known about how this immunotherapeutic strategy impacts the functional qualities of expanded T cells in the course of effector and memory responses. Using vesicular stomatitis virus (VSV) as a boosting vector in mice, we demonstrate that a massiv...
ZOSTAVAX(®) is a live attenuated varicella-zoster virus (VZV) vaccine that is licensed for the protection of individuals ≥50 years against shingles and its most common complication, postherpetic neuralgia. While IFNγ responses increase upon vaccination, the quality of the T cell response has not been elucidated. By using polychromatic flow cytometry, we characterized the breadth, magnitude, and...
The latest probable scenario in vaccination strategies is to prime one live attenuated vaccine candidate followed by boost dose of second vaccine candidate. In the present study, we primed the mice with a recombinant Bacille Calmette-Guerin (BCG) comprising Ag85B and ESAT-6 followed by boost doses of Ag85B, ESAT-6 and Ag85B-ESAT-6 fusion protein in the DDA adjuvant, separately. After boost dose...
The invention of vaccine has significantly reduced the levels of morbidity and mortality from infectious diseases. However, the success of vaccines is often impaired by the free-rider problem: while vaccinated individuals incur the cost of vaccination, unvaccinated individuals are protected from the disease given that population immunity is in effect. This provides self-interested individuals a...
Mucosal immunity is deemed crucial to control sexual transmission of human immunodeficiency virus (HIV). Herein we report the efficacy of a mucosal HIV vaccine strategy comprising intranasal (IN) vaccination with a cocktail of live recombinant human rhinoviruses (HRVs) encoding overlapping fragments of HIV Gag and full length Tat (rHRV-Gag/Tat) followed by intradermal (ID) vaccination with DNA ...
For protection against intracellular bacteria such as Mycobacterium tuberculosis and Listeria monocytogenes, the cellular arm of adaptive immunity is necessary. A variety of immunization methods have been evaluated and are reported to induce specific CD8(+) T cells against intracellular bacterial infection. Modified BCG vaccines have been examined to enhance CD8(+) T-cell responses. Naked DNA v...
