There’s no evidence whatsoever to support that.

So then natural immunity is fine as well as those vaccinated not needing booster shots.

Yes, I would agree with that.

I would say that a Delta-specific shot would be helpful in reducing the risk of transmission, but anyone who is vaccinated or who has recovered from infection seems to have excellent protection against severe illness and death.
