That's one consideration of a possible issue, not a key reason it was retracted

The "cautionary" part of the cautionary tale referred to in the article title is that a working vaccine was retracted mainly due to unfounded fears

e.g from the article summary "Just 3 years later, the manufacturer voluntarily withdrew its product from the market amidst media coverage, fears of vaccine side-effects, and declining sales. This paper reviews these events in detail and focuses on the public communication of risks and benefits of the Lyme vaccine and important lessons learned."

The "public communication of risks" not the actual risks.
