Heir Stamm, J., Serban, N., Swann, J. "Accessibility and Availability of Vaccine in the 2009 H1N1 Vaccination Campaign", published by the Health Analytics Group@GT.

This data descriptor presents small-area estimates of spatial access to H1N1 vaccine derived using optimization modeling with individual choice constraints, for the states of Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, and Tennessee. Estimates are included for both the overall population and for the sub-population of children and young adults (ages six months to 24 years). The latter constituted an important priority group in the H1N1 vaccination campaign. Spatial access measures considered are Proximity and Scarcity.

Proximity pertains to the distance barriers that patients experience in reaching their providers, measured as travel distanceScarcity pertains to the number of people seeking vaccine at a facility relative to the number of vaccine doses available there. 

These estimates can be used to identify locations for targeted improvements in spatial access to H1N1 vaccine and to quantify local disparities in access.


The data file attached with this descriptor includes the following columns:

ST_FIPS – Two-digit FIPS (Federal Information Processing Standard) state code

CO_FIPS – Three-digit FIPS (Federal Information Processing Standard) county code

TRACT – Six-digit census tract code

Y – latitude

X – longitude

ServiceAvgAll – Average scarcity (persons per vaccine) experienced by all individuals in the corresponding census tract

DistanceAvgAll – Average distance (miles) traveled by all individuals in the corresponding census tract to receive vaccine

ServiceAvgPriority – Average scarcity (persons per vaccine) experienced by the sub-population of children and young adults ages six months to 24 years in the corresponding census tract when vaccine is available only to the sub-population

DistanceAvgPriority – Average distance (miles) traveled by the sub-population of children and young adults ages six months to 24 years in the corresponding census tract when vaccine is available only to the sub-population

  • Equal opportunity to be healthy is a right not a privilege, and therefore, healthcare is a common good, not a market commodity.

  • Equal opportunity to be healthy is the attainment by all people at the highest possible level of physical and mental well-being that biological limitations permit.

  • "We use the CT scan because it’s a great defense," says the CEO of another hospital not far from Stamford. "For example, if anyone has fallen or done anything around their head — hell, if they even say the word head — we do it to be safe. We can’t be sued for doing too much."
