Hello All, I am new to this site and will be starting the LVN nursing program in May of this year. I have had so many injections that I feel like I glow in the dark! I am trying to understand how my titers for MMR and Varicella came back negative when I had a raging case of chicken pox and I also had mumps as a child. How could the titers be negative? So far, I have had HepB #1, HepB #2, Tetorifice, TB test, MMR, and Varicella injections. I still have HepB #3 and the follow up MMR and Varicella to look forward to. Any explanations as to where my antibodies went? Please? Thanks!
