I just got accepted into nursing school and I need to get my MMR shots and Tdap as well as a two- step mantoux done before December 23rd. I scheduled to have my mantoux done tomorrow morning but I went into my local pharmacy and had my first MMR shot today. I just read somewhere you have to wait to get tested 28 days after you had the MMR shot :/ I had no idea about this... Anyway my question is, am I absolutely required to wait 28 days? Im just really struggling to get everything done in time...
