Can anyone help me out?  If a new hire does not have vaccine records to prove MMR vaccination – we run titers.  If the titer for rubeola shows no immunity but rubella shows immunity – should the employee receive one or two MMR’s?  Do you run repeat titers after a period of time?  Do you allow them to start working with only one vaccine? Can you also provide a resource of how to determine this requirement?  Thank you in advance!
