Hi there, I've posted this on the general forum, but wanted your advice as well, as I've read your book and found it very informative. My two kids, 3 and 5 are not vaccinated. I feel pretty confident about that these days. We typically visit family in Israel in the winter, but I now understand that there has been detection of the polio virus in sewage in southern Israel and they've identified individual 1000 carriers in the south of the country. It's the same strain that is endemic to Pakistan. The Israeli government is now working on the innoculation of 150,000 kids in southern Israel with the newest live polio vaccine. So my questions are: 1. Should I visit Israel this year, and if so, do I need to vaccinate my kids? 2. If I do vaccinate my kids, would you recommend just the single polio dose vaccine, versus the combo diptheria/tetanus/pertussis/polio vaccine? 3. Do I need to be worried about my kids coming into contact with friends or relatives who have travelled to or will travel to Israel? Many people in our community and at my daughter's school regularly travel to Israel. Any advice you have would be much appreciated.
