I was thinking that vaccines in different companies may be cultured in different ways and made differently. And from what I read elsewhere, it sounds like many countries still have the seperate M M R shots available.
We will most likely be doing some world travel during my children's childhood and teenage years. We're going to Japan in the fall and in a few years parts of Europe and who knows where else later on (dh is fascinated with travel). Right now we don't vaccinate, but there are some vaccines I would consider if my kids hit adolescence with titers showing they do not have immunity.
I'm wondering if there is a good source to research vaccines available in other countries, who makes them, etc.? I figure it's something to consider if we choose vaccines later if "safer" ones are available in other countries we might be visiting, or if ones I don't object to morally (i.e. the rubella vaccine in Japan is not cultured using a cell line from an aborted fetus like it is here).
