We had a Hepatitis B vaccination before our first holiday to Australia and later a second one that the nurse told us would see us through - meaning until we die! No side affects, it just seemed a sensible thing to do.
Someone else told me to get my mammogram X Rays (or whatever they are) to take with me, because they like to compare the last two results with current mammograms - that was much easier than I thought, just rang up the unit, they put them in the post with an invoice.
