Masks required in public indoor spaces on campus 

CU Boulder will return to requiring masks in public indoor spaces regardless of vaccination. The requirement takes effect Friday, Aug. 13, 2021.

Considering the increasing rates of the COVID-19 delta variant, this decision was made to support the public health and safety of our community and support a consistent in-person experience this semester. Read more about this temporary measure.

Campus leaders hosted a Campus Q&A on Tuesday, Aug. 10, to answer questions about this requirement and plans for the fall semester. A recording of the Q&A session is available.

Contact tracing

CU Boulder’s Public Health Office will continue to provide COVID-19 case investigation and contact tracing this year. Any person who tests positive on campus will have an investigation conducted within one day. Based on case investigation and contact tracing, the Public Health Office will provide guidance on quarantine and isolation as well as any classroom management, if appropriate.

Please follow official public health guidance provided by the Public Health Office or local authorities; do not create your own. Visit CU Boulder Health and Wellness’ Public Health page for information on contact tracing, quarantine and other guidance.

COVID-19 vaccination requirement

The deadline for all CU Boulder students, staff and faculty to complete the COVID-19 vaccine requirement process is Sept. 15, 2021. Only vaccines that are approved by the World Health Organization (WHO) will meet the CU vaccine requirement.

 There are two ways to complete the vaccine requirement:

  • Proof of vaccination
  • Vaccine exemption

How to complete the requirement:

Note: Those who complete their requirement by the deadline will be entered into a drawing. Click the instructions above to learn more.

Students, staff and faculty will not get immediate confirmation that proof of vaccination or vaccine exemption was successfully submitted. However, faculty and staff will receive an email stating the COVID-19 vaccination requirement was completed after the submission is verified. Students will receive an email stating they have completed their requirement only when all vaccination requirements are complete. In either case, the process of verifying records and sending confirmation of receipt may take 7–10 business days.

 Frequently asked questions

Why is the vaccination requirement deadline after the semester starts? Will that cause a surge in cases?

Vaccinations have been widely available for months, and there are multiple opportunities to get vaccinated on campus in August in order to give everyone the ability to get vaccinated long before the requirement. The requirement deadline is the standard deadline for all CU Boulder vaccines and is the date for submitting your proof of vaccination; everyone is encouraged to get the vaccine as soon as possible.

With the population increasing in Boulder county as part of move-in, a surge in cases is possible. The mask requirement is a supplemental measure to help mitigate that possibility.

What do I do if I see someone not wearing a mask in an area they should? 

You can politely remind people of the mask requirement or point out nearby signage. Please do not force anyone to wear a mask. There are necessary exceptions in place. The best way to prevent COVID-19 spread is to get the vaccine; masks are a supplemental measure to help ensure we can maintain in-person operations.

How many people on campus have been vaccinated? How many have submitted exemptions? Why are exemptions allowed?

The COVID-19 dashboard will be updated with the available information about completion of the vaccine requirement. Exemptions are part of all campus vaccine requirements.

Why are vaccines required if we still need to wear masks? Does that mean the vaccines don’t work?

The most effective tool against serious illness from COVID-19––including the delta variant––is vaccination. Masks are a supplemental tool. 

I’d like to put up a sign near my office about masks. Is there one available?

Yes. Mask signs are available for download.
