I truly wish that a lyme disease vaccine gets released in the near future. I got it twice (!) within two years when I was younger and boy was I sick. At least the first time. It is not fun at all, though I seem have managed without any permanent problems as far as I know.

I did not get sick until something like 4 months after getting bitten, which lead in turn lead to the diagnosis being delayed a lot. Not fun at all.
