@milly she has been peer reviewed and her writing found to be inadequate. This is why she is not being published in the places she wants to be published.
Which hasn't stopped her gaining a high profile and a loud voice in many public spaces.
Even with the minor postgrad education I have on epidemiology I can see that her main assertions are not borne out in real world applications... Unless you are also asserting that the global infection data is being manipulated, that the published data is incorrect?!?
Think about what she is saying, not her figures, her main assumptions. If she is right what do you think infection rates would look like now, would have looked like over the last few months?
Take either of her her immunity % rates, it doesn't matter which.
Work it through. What do you get?
