Entrance Requirements for New Students
All incoming students (new, transfer, and graduate, including students in Veterinary Medicine, School of Law, School of Nursing programs, and undergraduates transitioning to a graduate or professional program) are required to meet the UC Immunization and TB Risk Screening requirements.
Immunization (IZ) Holds
To register for your second term at UC Davis, you must meet the University of California’s immunization requirements. When you complete your Statement of Intent to Register (SIR), an “IZ hold” is placed on your account. This hold will prevent you from enrolling in classes for your second term at UC Davis. This hold is cleared by becoming compliant with the requirements.
Please refer to OASIS to determine if you have a hold.
For example, if you start as a student in Fall 2026, your IZ hold will block your registration for Winter 2027 classes if you haven’t met the immunization requirements by your registration time for Winter 2027.
Individual School/Program Requirements
Individual schools or programs may have additional requirements. Program specific requirements can be found in the program’s student handbook or syllabus. For submission of program specific requirements, refer to your program. Example: Veterinary Medicine Student Requirements
COVID-19 and Influenza (Flu) Immunization Requirements
Neither the COVID-19 nor the flu vaccine are considered entrance requirements, and they are NOT associated with your IZ hold.
The University of California requires all students, faculty, and staff who live, learn, or work on campus to stay up-to-date with their COVID-19 vaccinations. If you prefer not to receive the vaccine, you can opt out by submitting a declination form. To comply with the policy, students must either upload and enter the dates of your COVID-19 vaccination information or submit the declination form through Health-e-Messaging. Please note that the COVID-19 vaccination requirement does not affect your ability to register for classes.
Each year, the University announces a seasonal flu vaccine mandate, typically in October. This mandate also does not affect your registration status. The deadline to enter this year’s date of vaccination and upload proof of your flu vaccination or submit a declination form via Health-e-Messaging is generally around November 1. For most current information on flu vaccine requirements, please visit Campus Ready.
Uploading and Entering Entrance Immunization Records
To enter your vaccination information follow these steps:
Step 1
Go to Health-e-Messaging click on “Requirements and Forms.” This section also includes forms and vaccines that are not considered Entrance Requirements. Your specific immunization requirements will be listed under “Items required for clearance.”
Step 2
Update your Records. Click the green “Update” button next to the requirement you want to enter. Follow the instructions on the pop-up to add your vaccination history or blood tests.
Step 3
Enter your Vaccination Dates. For each requirement you need to:
Enter the dates of your vaccinations or blood tests (also known as titers).
Note: You only need either a vaccination or a blood test, not both, to meet requirements.
Step 4
Upload Documents. Click the white “add Immunization record…” button at the top of the page to upload your proof of immunization or titer blood test results. You can also upload these documents as you are updating each requirement.
Upload proof of your immunization or blood test results. You can use a PDF, photo, or document.
Please ensure your file name only contains alpha-numeric characters (e.g., Abc123)
TB Screening, TB Testing, and TB Health Assessment Form (or TB Screening Form) Requirements
All incoming students must complete a Tuberculosis (TB) screening questionnaire.
To access the survey, click on the “Update” button next to “TB Screening.”
This will open the questionnaire. Your answers will influence if you need to provide further documentation. Please answer all five (5) questions and click the “Submit” button.
If you make a mistake on your TB screening form, please message our TB/Immunization nurses through Health-e-Messaging. You may need to refresh the webpage to see the requirement change to “Compliant.”
If additional documentation is required, a pop-up window titled “Further Action Necessary” will appear. If you close this window, you will see the new requirements under “Items required for clearance.”
Additional documentation required might include proof of a negative TB test completed within the 12 months prior to the start of your first term and/or a TB Health Assessment Form.
To meet the TB testing requirement, you can choose either a laboratory blood test or a skin test.
A chest x-ray without a previously positive test does not meet the TB testing requirement. If you have ever had a positive skin or blood test, you will also need to submit a chest x-ray. Once you have your test results, enter your test dates and upload a copy of your records under “Requirements and Forms.” Be sure to select your results and enter the date in the month/day/year format. If you need to upload your documents at a later date, you can do so by clicking the green “Update” button.
If a TB Health Assessment Form is required, it must be completed by your healthcare provider. Once any required testing is complete and your provider has determined you are free of active TB, the provider must fill out and sign the form. Chest x-rays submitted with your TB Health Assessment form must have been taken within 12 months before the start of your first term.
Please note:
The TB Health Assessment Form must be completed in English, signed and dated by a licensed healthcare provider (DO, MD, NP, PA), and include your name, date of birth, and/or student ID number. Forms that are incomplete or written in a language other than English will not be accepted and your “IZ” hold will NOT be cleared.
Please allow 14-21 business days for your documentation to be processed.
