Caterina - I assume you are no longer attempting to help me change my mind about you.
Imageine your arguments seem every now and then to contain some extraordinary claims.
Here's one: "Firstly the idea that improved hygiene and nutrition means that children now healthy enough to withstand infections (without need for vaccines). This is a fallacious argument."
If it were fallacious, the human race would have become extinct long before vaccines were invented or conceived, probably long before measles evolved
I don't think this extraordinary claim needs any further attention - if you'll excuse the term - it's utterly ludicrous.
That malnutrition damages the immune system: true: but so do vaccines in some children. Any look at the rise in auto immune disease which has accompanied the growing vaccine schedule should give any normal person pause for thought.
"Even the best nourished can and do get ill": of course: the getting ill, the rash, the cough, the fever, they are signs that the body is fighting the infection. Being well nourished doesn't mean you won't get ill: it means you'll be able to recover with immunity.
In addition the received wisdom about small pox is that it was eradicated by vaccine. Sometimes a look at figures can challenge the received wisdom: I believe there are statistics on other threads indicating that only 10-20pc of the population was ever vaccinated (which makes sense for the age) and that outbreaks swiftly followed what vaccination campaigns were carried out.
You don't have to be interested in that but I believe there some challenges to the customary view.
