From the Key Messages: " As of March 16, FEMA has provided more than $4.38 billion to 40 states, Washington D.C., four tribes and five territories for expenses related to COVID-19 [coronavirus disease 2019] vaccination at 100% federal cost share. These funds cover critical supplies, staffing, training and transportation needs that support increased vaccination efforts.  FEMA is working to speed up vaccinations by supporting states as they open community vaccine centers across the country, and working with its interagency partners continue to stand-up and provide support to additional sites daily. Each state determines its own vaccination priority groups and procedures. Community vaccination centers are led by states, but may be supported by the federal government, including FEMA.  FEMA and its partners have established Mobile Vaccination Centers, including pop-up locations, to bring vaccines closer to the communities and people that need them. The mobile vaccination capability is another way FEMA is supporting communities and getting vaccine services to hard-to-reach and high-risk populations who cannot access services from larger, fixed sites."
