  • Document appears unrelated to vaccination record

If you have questions about why your document has been declined or need additional help with your MacCheck upload, please email vacc@mcmaster.ca as soon as possible.

I have not uploaded proof of vaccination to MacCheck. What do I do now?

If you have not uploaded proof of vaccination to MacCheck, you are not cleared to come to McMaster unless you have an approved human rights exemption.

This means that you cannot attend campus or a McMaster-affiliated site for any reason, including but not limited to:

  • Attending an in-person class
  • Attending your place of work
  • Visiting the library
  • Attending an appointment or using a service
  • Going to a campus eatery
  • Attending a meeting on campus
  • Using the gym or athletic facilities

This also means that there may be impacts on your course or program progression for students and employment status for faculty and staff.

If you are fully vaccinated but missed the deadline to upload, please upload your proof of vaccination to MacCheck immediately. This applies to staff, students and faculty who are working on-site or remotely. You are not cleared to come to McMaster until you do so.

If you are partially vaccinated and are waiting for your second dose, please continue with your vaccination course and upload proof of your second dose to MacCheck as soon as you receive it. In the interim you are not permitted to attend a McMaster location.
