Hep A vaccination while pregnant Q

Ladies, I am 20+ weeks and I work in a restaurant. The health department is coming this Thursday because another employee was found to be positive with Hep A. They want us all to take the Hep A vaccination. I will discuss this with my doctor but not 100% sure I can get an answer before 9:30 a.m. this Thursday. I've googled the question and I saw conflicting statements. It says Hep B vaccination is safe, read a few about A being ok but look at this post...any insight or advice??
