Memory B/T cells

  1. Jul 29, 2008 #1
    I've learned about memory B and T cells. I'm wondering how many of each a person has for a specific antigen? How long do they live?

    I don't know the exact numbers, but when you look at tetanus vaccinations you need to get a booster after 10 years. So they can live up to ten years.

    Here a study who looked at it in detail: http://www.jimmunol.org/cgi/content/full/171/10/4969#F1
