I wouldn't think that animals would be able to pass things on? I just keep the good old wet wipes on hand in that situation (actually I don't leave home without them anyway!!! lol), but everyone should wash hands after petting animals vacced or not.

My kids don't swim at public pools until they are way over 12 months, I kept them both out of childcare until they are older (I would do that vacced or not tho)......ummm I can't think of any other situations that require me to change anything else.

ETA - its a good idea to read up and check how the various forms of Hep are spread so you feel better about those situations.
