Question: 

I have 2 documented doses of MMR. However, a recent lab test shows that I have no immunity to rubella. I'm a health care worker of child bearing age. Am I eligible for a 3rd dose?

Answer: 

Individuals who have documentation of having received one dose of a rubella-containing vaccine are considered to be immune, and testing for immunity is not routinely recommended. However, as you have had recent bloodwork which indicates a "non-reactive" result, we recommend that you contact your local public health unit and/or workplace health program to discuss your situation further.  You can find the contact information for your local public health unit here
