If you were negative, how many injections are needed for a positive? I'll get my titer results this week and I fear I'll be negative as I received my first injection before one year of age.
The other schools I attended pre-nursing accepted my immunization records, but the school I need to register for now will not. I'm nervous as classes are filling up and I can't register until I have proof for measles. How many injections will I need and how far apart do they have to be?
