I have seen so many different things found in VAXXXes
All i can say is that each batch is provably different.

But what was in them can only be described as bad, or worse... or saline

I doubt we will see conclusive proof of anything in the VAXXX.
Not until we have some huge study with dozens of labs working on a sample from every batch they can find. And everyone working on it has a huge hatred for the CDC and WHO.

I expect someone will do a huge database scouring thing in about 10 years and piece together something of what was done.

I am sorry about what happened to your father.
