I don’t know how to break this to you but wikepedia thinks naturalness is a conspiracy/fake news website:
https://en.m.wikipedia.org/wiki/Natural_News
But also more seriously I have looked into this Whooping cough outbreak and guess what I found behind the fake headlines?
The outbreak may well have been amongst previously vaccinated individuals and it is now thought that it is because the effects of the vaccines do not last as long as previously thought and that the answer is therefore more vaccination not less. Win win .
I will leave you to exercise your googling to find this out from a proper scientific source, but if you need help, do come back to me.
