Journal ArticleDOI
Trained innate immunity as underlying mechanism for the long-term, nonspecific effects of vaccines
TL;DR: The mechanisms of trained immunity responsible for the long‐lasting effects of vaccines on the innate immune system, including BCG, measles vaccination, and other whole‐microorganism vaccines are presented.

How advances in immunology provide insight into improving vaccine efficacy
Mark K. Slifka,Ian J. Amanna +1 more
TL;DR: The form of the vaccine antigen appears to play an important role in determining immunogenicity and the interactions between dendritic cells, B cells and T cells in the germinal center are likely to dictate the magnitude and duration of protective immunity.

TL;DR: The presence of a functionally competent YF-specific memory T-cell pool 18 years and sufficient titers of neutralizing antibodies 35–40 years after first vaccination suggest that single vaccination may be sufficient to provide long-term immunity.

TL;DR: Eventhough serological correlates of protection for yellow fever are unknown, seronegativity in vaccinated subjects may indicate primary immunisation failure, or waning of immunity to levels below the protection threshold.
Journal ArticleDOI
Questions regarding the safety and duration of immunity following live yellow fever vaccination
Ian J. Amanna,Mark K. Slifka +1 more
TL;DR: Current recommendations to no longer administer YFV-17D booster vaccination be carefully re-evaluated, and that further development of safer vaccine approaches should be considered.

Epidemiology: An introduction
TL;DR: This chapter discusses epidemiologic thinking in clinical settings, the role of statistics, and methods for controlling Confounding by Stratifying Data.

Yellow fever vaccine
TL;DR: The genus Flavivirus is a member of the family Flaviviridae, a group of small, enveloped, positive-sense, single-strand RNA viruses as mentioned in this paper.
International Travel and Health
TL;DR: It is advanced that a moderate amount of travel exercise would improve physical and psychological health, but an amount of prolonged travwl exercise could do harm to body, so the traveller should pay attention to regulate and protect from diseases through a right travelling exercise.

Persistence of neutralizing antibody 30-35 years after immunization with 17D yellow fever vaccine
TL;DR: This study suggests that antibody to 17D YF virus, as measured by the plaque-reduction neutralization test (PRNT), persists for 30 years or more following administration of a potent vaccine.
