Second only to safe drinking water in preventing illness and death, immunizations save approximately three million lives a year or nearly 10,000 per day world-wide.

The City-County Health Department (CCHD) provides vaccinations for children and adults of all ages. We accept walk-ins for most routine immunizations every Monday-Friday 8:00am-5:00pm (closed for lunch from 12:00-1:00).

Immunization Information by Age Group

RSV Immunization

New immunizations for respiratory syncytial virus (RSV) were recently approved.

People infected with RSV usually show symptoms within 4 to 6 days after getting infected. Symptoms usually include runny nose, decrease in appetite, coughing, sneezing, fever, and wheezing. Most RSV infections go away on their own in a week or two. However, RSV can cause severe illness in some people, especially infants, young children, and the elderly. 

During the 2022-2023 respiratory infection season, Cascade County had 456 confirmed RSV cases. 

CCHD is currently offering RSV immunizations for:

  • Adults age 60 and older
  • Babies 8 months and under (available until the end of March 2024)
  • Children 8-19 months who remain at risk of severe RSV disease


Please bring proof of insurance to every visit.

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 your insurance does not cover immunizations, you may qualify for a free or reduced cost immunization.

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.
