Insights into human CD8(+) T-cell memory using the yellow fever and smallpox vaccines.
Summary of "Insights into human CD8(+) T-cell memory using the yellow fever and smallpox vaccines."
Live virus vaccines provide a unique opportunity to study human CD8(+) T-cell memory in the context of a controlled, primary acute viral infection. Yellow fever virus-17D and Dryvax are two such live-virus vaccines that are highly efficacious, used worldwide and provide long-term immunity against yellow fever and smallpox respectively. In this review, we describe the properties of virus-specific memory CD8(+) T cells generated in smallpox and yellow fever vaccinees. We address fundamental questions regarding magnitude, functional quality and longevity of the CD8(+) T-cell response, which are otherwise challenging to address in humans. These findings provide insights into the attributes of the human immune system as well as provide a benchmark for the optimal quality of a CD8(+) T-cell response that can be used to evaluate novel candidate vaccines.Immunology and Cell Biology advance online publication, 8 February 2011; doi:10.1038/icb.2010.155.

Medical and Biotech [MESH] Definitions
Yellow Fever Vaccine
Vaccine used to prevent YELLOW FEVER. It consists of a live attenuated 17D strain of the YELLOW FEVER VIRUS.
An intermittent fever characterized by intervals of chills, fever, and splenomegaly each of which may last as long as 40 hours. It is caused by BARTONELLA QUINTANA and transmitted by the human louse.
An autosomal recessive trait with impaired cell-mediated immunity. About 15 human papillomaviruses are implicated in associated infection, four of which lead to skin neoplasms. The disease begins in childhood with red papules and later spreads over the body as gray or yellow scales.
Yellow Fever Virus
The type species of the FLAVIVIRUS genus. Principal vector transmission to humans is by AEDES spp. mosquitoes.
An acute infectious disease primarily of the tropics, caused by a virus and transmitted to man by mosquitoes of the genera Aedes and Haemagogus.
Yellow fever is a lethal viral hemorrhagic fever occurring in Africa and South America. A highly effective live vaccine (17D) is widely used for travelers to and residents of areas in which yellow fev...
The changing epidemiology of yellow fever and continued reports of rare but serious adverse events associated with yellow fever vaccine have drawn attention to the need to revisit criteria for the des...
A randomized trial was conducted to assess the immunogenicity and reactogenicity of yellow fever vaccines (YFV) given either simultaneously in separate injections, or 30 days or more after a combined...
Background. Vaccination of asymptomatic human immunodeficiency virus (HIV)-infected patients with a CD4 cell count >/= 200/mm3 is strongly suggested prior to travel to a region where yellow fever (YF)...
In October and November 2010, hospitals in northern Uganda reported patients with suspected hemorrhagic fevers. Initial tests for Ebola viruses, Marburg virus, Rift Valley fever virus, and Crimean Con...
The objective of this study is to study immune memory generated against the yellow fever vaccine (YFV) in participants who recently received the YFV vaccine. Volunteers who are planning...
The purpose of this study is to determine whether immune globulin can limit the amount of yellow fever vaccine virus present in the blood after vaccination without compromising the immunit...
The investigators at Rockefeller University are doing this research to study how the immune system responds to viruses and other infectious agents by using the yellow fever 17D vaccine as...
The purpose of this study is to obtain safety, tolerability, and immunogenicity data on the co-administration or sequential administration of Chimeravax™-JE vaccine and STAMARIL®. Obje...
The Phase 1 trial is a single-center, randomized, double blind, placebo-controlled, dose-ranging out-patient study designed to provide the first clinical data on the safety, tolerability a...
