Health Department Moves To No Appointment Necessary At The CARTA Bus Barn – The Chattanoogan

The Hamilton County Health Department is moving to a “no appointment necessary” system effective immediately and invites people seeking the Moderna COVID-19 booster shot to visit the Carta Bus Barn, at 1617 Wilcox Boulevard, Chattanooga, Tn. 37406. Hours of operation are Tuesdays-Saturdays from 9 a.m.–4 p.m. No appointment is necessary.

Moderna, Pfizer and J+J COVID-19 vaccines have received approval to ‘mix and match.’ This means individuals can choose which COVID-19 vaccine they want for their booster shot, even if they received their primary series from a different vaccine manufacturer.

Moderna booster shots are for individuals 18 years of age or older who finished their Moderna or Pfizer primary series after six months AND individuals 18 years of age or older who completed their J+J primary series after two months.

Only Moderna booster shots are available at the Carta Bus Barn, not the primary series.

To Prepare for the Moderna Booster at the CARTA Bus Barn

For Moderna booster eligibility, please visit the Health Department’s website at and click on “COVID-19 Booster Eligibility.”

Visit and complete the booster encounter form under the “Handouts” tab.

Forms will also be available on-site.

Bring your “Vaccine Record Card” with you. This card has information about your previous doses, including dates of injection and vaccine manufacturer.

If you lost your card and received your primary series in Tennessee or Georgia, Health Department staff will look up your information in the vaccination system upon arrival.

If you received your primary series from any other state except Tennessee or Georgia, you will need to bring your vaccination record with you.

Please wear loose fitting, short sleeve clothing to your booster appointment.
