Irvine seems ahead of UCLA (with emphasis on "seems")

It appears that UC-Irvine is running somewhat ahead of UCLA in terms of vaccinating employees in the second tier group based on the announcement excerpted below. The caveat is #2 in the excerpt - vaccine availability. Do they actually have the vaccine in sufficient amounts to do what they say? Or is what is being announced just a plan:

Vaccine Distribution - Employees

Vaccine distribution for UCI employees will begin in carefully planned phases beginning the week of January 18. Employee eligibility will be based on two things:

1. Federal, state and county guidelines
2. Vaccine availability

The first phase will include UCI employees aged 65 and over, plus all campus housing and dining employees. 

Invitations to schedule vaccinations will be sent to employees’ UCI email addresses from the UCI Health system when the employee is eligible for vaccination.  

An employee is currently defined as: faculty, other academic appointee, faculty emeriti, and career, contract, temporary, and part-time staff.

Retired staff who are not currently active on UCI payroll are not eligible and should follow county guidelines for obtaining their vaccinations.

Student employees will be eligible for vaccinations as part of the student vaccination program and not as part of the employee vaccination program...
