COVID19 Vaccinations - Where and How to Get Vaccinated in Denver 

Vaccine supplies are currently very limited in Denver, and are currently being distributed according to the State of Colorado’s phased distribution plan. If you are eligible for the vaccine, see for how to sign up for an appointment or to be placed on a waitlist to receive it at one of Denver’s local healthcare providers.

The Denver Office of Sign Language Services (DOSLS) provides auxiliary aids and services to Denver City and County government agencies at no cost, with a minimum of three (3) business days’ notice requested. Last minute requests will be accepted but may result in the unavailability of an auxiliary aid or service.

Per Federal legislation, Americans with Disabilities Act (ADA), Deaf/ hard of hearing people are a protected class. Therefore, they are entitled to effective communication and equal access to all government programs, services, and events (ADA, Title II). Effective communication access will often mean the provision of an auxiliary aid or service such as an interpreter, open captioning via Communication Access Real-time Translation (CART), or an assistive listening device (ALD) for sound amplification.

Our Mission

Create access for Deaf, DeafBlind, and hard of hearing people to Denver government programs, services, and events by:

  • Providing sign language interpreting services, open captioning via Communication Access Realtime Translation (CART), and Assistive Listening Devices for sound amplification to Denver government agencies upon request;
  • Engaging members of the Deaf and hard of hearing communities in Denver City and County government affairs;
  • Educating and consulting with City and County of Denver employees regarding their responsibility under Title II of the Americans with Disabilities Act to provide access to the Deaf, DeafBlind and hard of hearing public;
  • Providing information and referral.
