We went to Thailand when DD1 was 2 and we all had HepA vaccinations before going. My Dr is Asian and she said that she wouldn't take her own children there without giving them the vaccine first. Given that it is fecal-oral and DD1 was still putting everything in her mouth we decided that it would be best for her to have it and DP got his done so that they could do it together I had already had mine done previously.
