I do not know if the current strain of Lyme disease was a result of gain-of-function research by the United States, but many documented incidents mentioned above are easy to check. I believe the circumstantial evidence is accurately described.
Henry David Thoreau springs to mind: “Some circumstantial evidence is very strong, as when you find a trout in the milk.”
Also, when you have substantial concrete evidence of similar, ongoing behaviors.
I have no problem believing the US government might have created a more virulent Lyme disease. At least one of the same players mentioned, Ecohealth, profited from CCP virus gain-of-function research and coverup.
Lyme’s increased virulence may not have been “bioweapons research”… in the same sense (semantic obfuscation) Dr. Fauci employs to deny Ecohealth used NIH money to finance Wuhan Lab conducted coronavirus GoF studies: It depends on the meaning of “is,” you see. To quote an ex-president and frequent flyer on the Lolita Express.
Lyme was definitely bioweapons research adjacent – to pluck a phrase from the CRT & Trans activist vocabulary.
Oh, BTW, while there is no human vaccine for Lyme, there is one for dogs. Make of that what you will.
