This was just discussed in the Adults forum, saveferris (Amy) has the evidence to date on her blog. I think our health system does not cover it b/c unfortunately the research available is not large or long-term enough to be considered more than pilot studies.
The vest is an expensive piece of equipment and as there are other comparible methods available the funding is not a priority. The USA free market health care system is more likely to purchase the vest, I assume b/c of how the product is marketed to the Dr's, thus Dr's are more likely to support it's use and push it through insurance. Do insurance companies require a level of evidence for an intervention before they pay for it?
I do think the pilot research has complelling results and wish I could try a Vest. Once I have had my baby I am going to trial one and look at pushing the funding through our federal Program of Appliances for Disabled People. I have worked in health care and have some inside knowledge that might help pull the right strings. If I can get it through there will be a precedent for other CF'rs
If that doesn't work I'll explore other campaining options.
I will let you all know how I go!
