Ok. Well, perhaps you aren’t actually aware of what the J&J is. I enjoyed the part about spreading bullshit though, good one.

No, there have been no previous live viruses that have been genetically modified to look like other viruses (embedding Covid spike proteins) injected in humans before three months ago in any scale.

We have treated animals with exactly this however, including pigs against piggy rona.

I recommend reading the whole post next time, not just stopping at “live virus”.
