This hesitancy may be particularly problematic given the magnitude of the second wave in neighboring India and the acceleration of cases across South Asia that threatens to overwhelm health infrastructure.

The planned investment to support COVID-19-vaccine adoption is more modest. For administration, Medicare plans to reimburse providers $28.39 to administer single-dose vaccines and, if two doses are needed, $16.64 for the first dose and $28.39 for the second.3Medicaid typically reimburs...
