AFAIK, you are correct but I’m not talking about that. I’m wondering what else was in the vaccines.
An example of what I am writing about is https://www.nature.com/articles/s41541-017-0024-6?error=cookies_not_supported&code=008fa910-ba6e-4eeb-840a-5439999b3897
My use of the subject at that link is intended to be an example of the increasing capabilities of science. It is not a claim that it is the specific cause for the outbreak of the recruit illness.
Since I do not have even a little bit of trust in this politically criminal controlled government my concern is DoD cooperation, knowingly or not, in the testing of an advanced means of population control. Where better for advanced testing than in a controlled environment of a military boot camp?
