The Lyme vaccine came out in the late 90s, was not covered by most insurance, and is no longer available. Lymes disease is terrible and not something any life extensionist would want to live with as it can cause permanent harm.
If I can get it for less than $150/ea including overnight shipping (has to be mailed w/ 1 day shipping and must be kept cold/refrigerated) , who would be interested? I'd need no less than about a dozen people. You'll need to get your doc to give it to you which might also represent a challenge.
If it turns out to be illegal, forget it, but if there's interest, I'll do the necessary research.
