Yes. There is no harm in getting two different vaccines at the same time. In fact, if you haven’t already been immunized against hepatitis A, consider getting that done too. The hep A vaccine requires two shot, and hep B needs three shots. If you did these separately, you’d have five shots in six months. Add in a flu shot, and you are up to six separate shots.
An easier approach is to request the combined hep A and B vaccine, called Twinrix. You’d get three shots over a six-month period. The flu vaccine brings this to four shots in six months. You’d be protected against hep A and B for life, and only need an annual flu shot.
