Rockland county’s proposed ban against unvaccinated minors: Balancing disease control, trust, and liberty
From the public health lens, we argue: (1) public health officials have the responsibility to protect the public from harm, especially in the context of an outbreak, (2) the pathogen’s epidemiology, including the severity of the disease, and transmission dynamics should inform the methods of disease control, and (3) public health officials have the authority to implement certain, scientifically sound control measures during an outbreak.
Beyond Neutralizing Antibody Levels: The Epitope Specificity of Antibodies Induced by NIH Monovalent Dengue Virus Vaccines
After monovalent vaccination, subjects developed high levels of nAbs that mainly targeted epitopes that are unique (type-specific) to each DENV serotype. The DENV1, 2 and 4 monovalent vaccines induced type-specific nAbs directed to quaternary structure envelope (E) epitopes known to be targets of strongly nAbs induced by wild type DENV infections.
In the absence of good animal models, Controlled Human Infection Models (CHIMs) are useful to assess efficacy of new vaccine candidates against Enterotoxic Escherichia coli(ETEC), as well as other preventiveor therapeutic interventions. At the 2018 Vaccines Against Shigella and ETEC (VASE) conference, a work-shop was held to further review and discuss new challenge model developments and key issues related to further model standardization. During the workshop, invited speakers briefly summarized for attendees recent developments and main agenda issues before workshop participants were divided into four groups for more focused discussions.
With the increasing geographic expansion of dengue and incidence of the disease in travelers, offering pre-travel vaccination against dengue would provide protection for hundreds of thousands of persons traveling to dengue-endemic countries, including tourists, persons traveling for business , military personnel and humanitarian aid workers.
As the world prepares to fight Lassa fever, the interests of pregnant women must be part of the planning
Lassa fever is on the World Health Organization’s R&D Blueprint of priority diseases and the Coalition for Epidemic Preparedness and Innovation (CEPI) has invested in the development of several candidate vaccines against Lassa fever, some of which will enter clinical trials this year.
Informing randomized clinical trials of respiratory syncytial virus vaccination during pregnancy to prevent recurrent childhood wheezing: A sample size analysis.
Vaccination of pregnant women against RSV may protect their infants against RSV illness during their first months of life, primarily through maternal antibodies transported across the placenta. While licensure of RSV vaccines for use during pregnancy is likely to be sought for the primary indication of preventing acute RSV illness in young infants, the public health value of maternal RSV vaccines would be greater if the vaccine also prevented wheeze-associated disorders.
Cutting Edge: Transcriptional Profiling Reveals Multifunctional and Cytotoxic Antiviral Responses of Zika Virus-Specific CD8+ T Cells
Zika virus (ZIKV) constitutes an increasing public health
problem. Previous studies have shown that CD8+ T cells
play an important role in ZIKV-specific protective immunity.
We have previously defined antigenic targets of
the ZIKV-specific CD8+ T cell response in humans. In
this study, we characterized the quality and phenotypes of
these responses by a combined use of flow cytometry and
transcriptomic methods, using PBMCs from donors deriving
from different geographical locations collected in
the convalescent phase of infection.
