Yet the delta mutation came about in India, where there were no vaccines.
And in fact, data shows mutations occur in unvaxxed people.
“And in fact, data shows mutations occur in unvaxxed people.”
Mutations happen constantly, without any provocation, in RNA viruses.
Covid-19 is an RNA virus. And as this 2009 virology paper on RNA transcription error states:
“RNA polymerases of RNA viruses are the kings of errors – these enzymes screw up as often as one time for every 1,000 – 100,000 nucleotides polymerized. This high rate of mutation comes from the lack of proofreading ability in RNA polymerases. These enzymes make mistakes, but they can’t correct them. Therefore the mutations remain in the newly synthesized RNA.
