I have no sauce yet but this is first hand information from Russian citizens.
The girl I work with is from Russia her entire family lives there.
Putin never allowed any vax from Pfizer or Moderna in Russia. They developed their own vax called Sputnik 4 Covid Vax. She said it was the traditional vax.
The developer was killed and they are still investigating.
We both think it is probably Big Pharma or US Government.
She also stated this.
Also as I am reading. There were terrorist attacks in Bryansk, which is Russian territory. They found NATO weapons there.
She is still digging and more will be updated.
She updated.
What I could find that the killed developer was Senior Scientific worker and was a co-author and a co-patent holder of sputnik vaccine. Russian media says they arrested the killer, and claim it was domestic argument that ended up in killing.
To me it is hard to believe that it was just domestic argument.
Russians not buying this narrative.
She is still digging.
