Antimicrobial resistant E. coli before and after California Senate bill 27 (ARES): a natural experiment
This study will allow us to comprehensively evaluate the casual link between food animal use of antibiotics, food product contamination, and human disease. These findings will inform future policy interventions towards a potentially modifiable source of AMR to reduce the burden on human populations nationally and globally.
Extended Herpes Zoster Vaccine Effectiveness in a Health Maintenance Organization
The objectives of this study are to conduct a retrospective cohort study to evaluate the long-term effectiveness of the zoster vaccine for preventing HZ and PHN among persons 60 years of age or older. Understanding the long-term duration of vaccine effectiveness will be critical for monitoring impact of the zoster vaccination program, as well as for informing policy decisions that the ACIP will face, such as the consideration of a booster dose, and determining the optimum age to begin vaccination.
GWU/Wellcome 1 Feasibility
To collect preliminary data to support the larger Wellcome grant.
Learning from California Senate bill 27: a natural experiment
This study complements an ongoing R01 study to provide more compelling evidence regarding the impact of SB27 by examining all major meat types (chicken, turkey, pork and beef) that may be impacted by the bill. Likewise, we include collection of the frank foodborne pathogens, Salmonella and Campylobacter, to provide additional insights into the potential effectiveness of this policy intervention.
