A relative of mine is strong believer in negative views of the Covid vaccination campaign. She linked me this as the basis for her belief that the vaccination campaign will result in a stronger strain of covid.

Is it any true? I personally don't believe so due to the reduced viral loads and numbers of transmission greatly reducing mutations instead of increasing their rate.

Now obviously even if all this were total and utter bullcrap I am under no such delusions that I could convince her, I am well aware how strongly people believe in these things and that pretty much nothing I can say could make her believe otherwise, similarly to how it is difficult to convince someone to leave a cult.
