Vaccinations

Data is pulled daily by TDH from the state immunization information system (TennIIS). Providers administering Covid-19 vaccines are expected to report vaccine doses to TennIIS within 24 hours of administration and are required to report doses no later than 72 hours after administration. Dates reflect the date the dose was reported in TennIIS—not the date the dose was administered.

Includes data for Hamilton County residents only. All types of providers are included (eg. health departments, hospitals, pharmacies, private practice, etc.). The denominator for calculating the total share of population vaccinated is the total population of the county.
