I actually personally remember considering getting the vaccine when it was available, since I spent quite a bit of time outdoors, and declining because my doctor and I were bamboozled into thinking the risks were real (that we now know to be faked).
The vaccine caused a number of issues. Given the nature of the bacteria, it's DNA and multiple forms, two of which are resistant to antibiotics (biofilm, round body-starvation form), it is not too feasible to develop a vaccine. It's a very capable bacteria. Try reading "Healing Lyme" by Buhner.
