When my child was born, my husband and I researched the safety of immunizations. We also read Neil Z. ******'s book. We have been happy with our decision not to immunize. This year, we are planning to travel to London after the Olympics. There has been a measles outbreak in the Ukrane and Europe, so now we are again facing this decision. I've been reading both sides again. My child has also been studying both sides of the issue, and does not want an MMR. Should our decision not to immunize be updated because we're hoping to travel?
