Protocols for Vendors Working on Campus

Updated November 10, 2022

To ensure the health and safety of the UCSF community, all vendors who come to work at UCSF campus locations are subject to the following:

Please note: All vendors and contractors must be approved by department heads or principal investigators; no higher-level approval is required.


Vendors: For the purposes of the policy below, vendors are defined as suppliers and contractors who perform services on UCSF property that involves more than just a quick delivery. Examples of work performed on-site by vendors includes equipment installations, repairs and servicing, gas refills and clinical research monitoring by research sponsors or third parties.

Booster: A booster means an additional dose of a vaccine authorized to prevent COVID-19 by the Food and Drug Administration (FDA), including by way of an emergency use authorization, or by the World Health Organization (WHO), for which a person is eligible.

Individuals who are 18 or older may receive a booster of the Pfizer-BioNTech or Moderna COVID-19 vaccine at least five months after receiving a second dose of the Pfizer or Moderna COVID-19 vaccine or two months after receiving the single dose Johnson & Johnson’s (J&J) Janssen COVID-19 vaccine. Adolescents who are 16 or 17 may receive a booster of the Pfizer vaccine at least five months after their second dose of that vaccine.

Consistent with U.S. Centers for Disease Control and Prevention (CDC) and California Department of Public Health (CDPH) guidance, either the Pfizer or Moderna COVID-19 vaccine is preferred for the booster. That preference applies to all initial vaccination series, regardless of which vaccine an individual received.

Up-to-date vaccination status is defined as meeting criteria in A or B:

  1. COMPLETED an initial FDA- or WHO-approved two-dose vaccination series more than 5 months ago (or one-dose J&J more than 2 months ago) and you have RECEIVED your booster.
  2. COMPLETED an initial FDA- or WHO-approved two-dose vaccination series less than 5 months ago (or one-dose J&J less than 2 months ago), and more than 14 days since you completed your vaccination series (i.e., NOT YET booster eligible)

A list of FDA-authorized vaccines is available.  A list of WHO-authorized vaccines is available.

Vendor Groups & Post-travel Requirements

Already Approved Vendors

All on-site work by vendors must be approved by Department Heads or Principal Investigators; no higher-level approval is required. Following initial approval of a vendor project, each individual site visits necessary to perform the work needs to be coordinated in advance with an appropriate UCSF contact. Vendors who travel to UCSF from outside California (regular commuters exempted) within the previous 10 days must adhere to the following:

  Testing Requirement for Vendors after Travel


From Another State

From Another Country

Up-to-date vaccination

Long-term Vendors with UCSF IDs

Some select vendors have been issued a UCSF ID and are on campus full-time or for extended periods of time (generally months or longer), such as those working in retail, food service and building operations. These vendors must also follow all the same policies and protocols as UCSF employees. Those who travel to UCSF from outside California in the previous 10 days (regular commuters excepted) should follow the UCSF return-from-travel requirements that apply to on-site workers and learners

Construction Contractors Hired Under UCSF contracts

Construction contractors hired by UCSF Real Estate and other campus units are required to adhere to the terms of their contracts and their site-specific health and safety plans. If they are entering UCSF buildings where UCSF staff or patients are present, then they must follow UCSF COVID-19 health, quarantine and testing protocols listed above for already approved vendors.
