I went for a job interview for a job I never thought I'd get. It was way more money than I'd ever been on and really local and good hours. As it was dental related they asked if I'd had my hep b vaccine in my previous job and I said yes. In reality I'd only had two of the vaccines about 5 years ago. Now I've got the job they want my certificate of immunity, which I don't have! The vaccine takes 4-6 months and I don't have that long but I just don't feel I can tell them. I could possibly only need a booster as I had 2/3 previously. Please don't judge me, I just needed a break and to pay my mortgage!
