MMR booster missing

1 min. readlast update: 07.10.2024

Your MMR titer proved to be non-immune. You will need to upload proof of another MMR vaccine dose. 

Or, if you suspect you already have immunity to MMR, you can also upload a MMR titer test in place of the MMR booster vaccine.

An MMR titer test is used to determine the presence and concentration of antibodies specific to the measles, mumps, and rubella viruses in an individual's blood.

You can have these titers done at your doctor's office or anywhere that performs blood testing or a lab.
