FAQ about the 2019 Measles Titer Clinic and Sharing Immunity Records

In 2019 and in previous instances where measles was suspected on campus, exposed employees were asked to provide proof of immunity with the instructions below. In the event of any future suspected cases, the process described below might not be followed exactly, but similar steps can be expected.

Sharing Proof of Immunity

If there is a case of measles on campus, you may be required to prove that you have immunity before you are permitted to return to campus. Sharing these records with Employee Health proactively, in advance of such a case appearing on campus, could help you avoid any inconvenience.

Three ways to share:

Can you prove that you are protected? Consider which of the following statements best describes you:

I was born before January 1, 1957.

You are considered to have immunity. No additional action needed.

I know that I am protected and I have proof.

According to the US Centers for Disease Control, to prove your immunity, you must have:

  • Vaccination records showing two doses of MMR (measles-mumps-rubella) or measles vaccine,
  • Medical report stating that you were previously infected with measles, or
  • Lab evidence (documentation of measles titer testing indicating acceptable level of immunity)

I think that I am protected, but I do not have proof and/or am not sure.

If you have no vaccination records or are unsure of your level of protection, a blood test called a titer will confirm your level of immunity. You can get a measles titer through your primary healthcare provider. Contact your insurance carrier for coverage information.

I am not protected.

For protection, you need two doses of the measles or MMR vaccine. This vaccine is available through:

  • Your primary healthcare provider and walk-in clinics. Contact your insurance carrier for coverage information.
