Yes, Marnica, the message remains the same. Little has changed. The same with natural/medicalized childbirth, but that is another forum.
There had been a global campaign to eradicate smallpox for centuries. The Chinese used a form of dried postule contents and sniffed it in centuries ago.
If smallpox were to be eradicated in this method, or by the new fangled medical method of scraping and then injections, why did it take so long?
An old chiropractor told me as a child that the UN workers go in to the villages and burn the associated clothing, bedding, clean the eating utensils, initiate irrigation and teach sanitary methods to the villagers. *THEN* everyone is queued up for the vaccinations; the credit for the success of the smallpox eradication in the village is given to the vaccine, NOT the sanitary conditions.
It was the sanitation practices of the twentieth century that finally eradicated smallpox. We should give the credit to our trash collectors and plumbers, not doctors.
