Characterization of Human Memory Immune Responses to Prior Yellow Fever Vaccination
https://clinicaltrials.gov/ct2/show/NCT01244802

Oct 18th, 2019 - The goal of this study is to characterize immune memory in humans who have previously received yellow fever vaccine. The project is designed to study the magnitude and persistence of both humoral, and cell-mediated immune memory generated post-vac...

Immunogenicity and Safety of Tetravalent Dengue Vaccine (TDV) Administered With a Yellow Fever Vaccine in Adults
https://clinicaltrials.gov/ct2/show/NCT03342898

Jun 20th, 2019 - The vaccine tested in this study is TDV also known as TAK-003 (DENVax). TDV with concomitant administration of yellow fever (YF-17D) vaccine will be tested to assess immunogenicity and safety in healthy participants in non-endemic area(s) for both...

Turnover of Antigen Specific Lymphocytes After Immunization With the 17D Yellow Fever Vaccine
https://clinicaltrials.gov/ct2/show/NCT01290055

Feb 11th, 2019 - In general, T cell responses to viral infections occur in three distinct stages: expansion, contraction and memory. During expansion, antigen-specific CD8+ T cells proliferate to increase in numbers as well as acquire the ability to kill virus inf...

Immunogenicity of Fractional One-fifth and One-half Doses of Yellow Fever Vaccine Compared to Full Dose in Children 9-23 Months Old
https://clinicaltrials.gov/ct2/show/NCT03725618

Oct 31st, 2018 - Yellow fever (YF) is a potentially fatal disease causing some 29,000 - 60,000 deaths in Africa alone in 2013. Vaccination with the YF vaccine is the most effective way of preventing YF and a single full dose of vaccine provides life-long protectio...

Human Immune Responses to The Yellow Fever Virus Vaccine
https://clinicaltrials.gov/ct2/show/NCT00694655

Oct 1st, 2018 - 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 to travel to yellow fever endemic areas will be recruited int...
