Immunization Information by Age Group


Clinics Poster updated 9.19.23

Additional clinic info: 

Children are welcome at any walk-in clinic (must be accompanied by a parent or guardian).

Please be advised that coming later in the day may reduce wait times, as the first few hours are the busiest.

Please bring your insurance card. All major insurance providers are accepted. If you do not have insurance, a standard dose flu immunization is $40 (cash/credit/debit/check) and a higher dose immunization is $80. If you are unable to pay, you may qualify for a free or reduced-cost flu immunization.

The new monovalent COVID-19 immunizations will be available at all clinics, while supplies last. You must bring your COVID-19 immunization card and insurance card.

At the walk-in clinic on 9/27, we will have new Pfizer doses for those with insurance, and a very limited supply of new Moderna doses only for adults without insurance or whose insurance does not cover Covid immunization. Medicaid does not cover COVID-19 immunization.

The new COVID-19 immunizations may not be available for all ages of children, due to temporary shipment delays - please call 406-454-5079 with any questions about availability of pediatric COVID-19 immunizations.


CCHD accepts all major insurance providers. Insurance covers many vaccinations, including flu shots. Please call 406-454-6950 or your insurance company to learn whether a specific immunization is covered, prior to receiving it.

If you do not have insurance or are under-insured (e.g., cannot pay your deductible), you may qualify for free or reduced cost immunization. No person is denied immunizations due to inability to pay!

Tuberculin Testing (Tuberculosis/TB Skin Tests or PPD)

The TB skin test is a two-part test. The first day, your forearm is injected with a small amount of PPD solution and then you must return 48 to 72 hours later to have your arm examined.
