Health insurance expansions may increase early detection of cancer and reduce late-stage cancer incidence. The study assesses the effects of the Affordable Care Act Medicaid expansions on rates of early- and late-stage cancer diagnosis up to 3 years after implementation. ⋯ Medicaid expansions increased early-stage cancer diagnosis in the first year of expansion, but effects dissipated in subsequent years, suggesting a response to pent-up patient demand for screening and diagnostic services immediately after expansion. There was also suggestive evidence of reductions in late-stage diagnosis in the third year of Medicaid expansion, highlighting the potential role of public health insurance in improving cancer outcomes among nonelderly adults.

Rapidly urbanizing communities in middle-income countries could be sources of vaccine hesitancy, and may create hot spots of low vaccination coverage. This study characterizes vaccine hesitancy in Shanghai and identifies disparities in vaccine safety and efficacy concerns by residency status-a marker for recent migration into the city. ⋯ This article is part of a supplement entitled Global Vaccination Equity, which is sponsored by the Global Institute for Vaccine Equity at the University of Michigan School of Public Health.
