COVID-19 Mitigation Protocol for CMU Vendors, Service Providers and Affiliates

Carnegie Mellon University requires all employees of all vendors and service providers performing services, and all affiliates visiting any campus or CMU facility to be fully vaccinated (including booster when eligible) against COVID-19, including a booster when eligible, unless unable to be vaccinated due to a disability or strong religious/moral conviction.

See additional information below for more details on how “vendors”, “service providers” and “affiliates” are defined for the purpose of these requirements.

Although not required, individuals who have been granted medical or religious exemptions from vaccination under applicable federal or state law are recommended to be tested for COVID-19 on a weekly basis. CMU’s Tartan Testing Program may be available for this purpose (see below for more details). Vendors, service providers and affiliates who do not use Tartan Testing are not required to provide test results to the university.

Facial coverings both indoors and outdoors are optional, but remain strongly recommended, for those who are up-to-date with respect to COVID-19 vaccinations. Those who are not up-to-date on vaccinations must continue to wear facial coverings while indoors.

Questions concerning CMU’s mitigation protocol should be sent to

“Vendors” and “service providers” are terms to refer to individuals or companies who have entered into contracts with CMU to perform services on campus or at any CMU facility. “Vendors” typically work on campus on a daily basis, such as Aramark’s custodial workers, Chartwells food service workers and the various food purveyors located in the Cohon University Center and in other buildings on campus. “Service providers” generally refers to individuals or companies who provide a variety of different services on an intermittent or project-by-project basis, such as consulting, equipment and facility maintenance and repairs, events catering, photography, coffee and water service, moving and storage.

Vendors and service providers and their workers are not employees of CMU. Thus, the vendors and service providers who have entered into a contract with CMU are responsible for communicating CMU’s COVID-19 mitigation requirements to its workers, and for ensuring that they are followed. 

Individual employees of vendors and service providers are not required to report their vaccination status to the university. Likewise, individuals who are exempt from vaccination for medical or religious reasons are not required to provide weekly COVID-19 test results to the university. However, the university may request aggregate data from vendors or service providers regarding the vaccination rates and COVID-19 testing results. Vendors and service providers should work with their primary university contact to discuss the availability of Tartan Testing for those who have been granted an exemption from the vaccination requirement.

An affiliate is a recurring university visitor hosted by a faculty or staff member. Affiliates are not required to upload their vaccination details in CMU’s health services system(s). However, affiliates may be asked to attest to and provide details on their vaccination status to the university. If you are an affiliate, please connect with your sponsor to clarify whether and how you need to complete these requirements. Those who host affiliates should consult with for guidance on if and when individuals are expected to provide such details.

Affiliates who are exempt from vaccination requirements for medical or religious reasons are required to be tested for COVID-19 on a weekly basis. Affiliates are responsible for making their own arrangements for testing. However, Tartan Testing, the university’s asymptomatic COVID-19 testing program may be available to affiliates, who should work with their host to determine eligibility. Affiliates who do not use Tartan Testing are not required to provide test results to the university. However, they may be asked to attest to having received a negative COVID-19 test within the last 72 hours to their host.
