Compulsory vaccination in the UK (which actually still didn't mean anywhere near universal coverage - I think around 70% of children were vaccinated at the turn of the century and this had dropped to under 50% by the 40s) ended in the late 1940s so before that 'new and improved' vaccine became available. This means that when the biggest drop was taking place the less effective and more dangerous vaccine (by your own admission) was the one in use. A bit strange that with compulsory vaccination for nearly 100 years it still didn't eliminate the disease. Hardly a brilliant and effective vaccination campaign!
Out of curiosity - how do you explain the drop in the fatalities of measles and scarlet fever that were occurring at the same time without the vaccine? Can you consider the possibility that the same things that were influencing them could be influencing smallpox too?
re Vitamin A I did not say that it provided 100% protection - I quite specifically said that it reduced complications by 50%. (All complications by the way - not just fatalities) This shows that nutrition does actually have an impact - something which you seem to be denying and giving all credit to vaccines which is a bit silly given that the greatest decrease in fatalities occurred prior to the vaccine being introduced. (Have you even accepted that yet?) Children who are well nourished are less likely to suffer complications from measles - quite dramatically so. From the WHO on measles:
"Some children infected with measles virus may have only a mild illness, with few signs or symptoms. This is fortunate for the child but makes the clinical diagnosis harder. Other children may have severe complicated measles with more obvious signs and symptoms and are generally much sicker. Children at greatest risk of developing severe complicated measles include:
? the young, particularly those who are under one year of age
? the malnourished (children with marasmus or kwashiorkor)
? those living in overcrowded situations (e.g. the urban poor, refugee camps) where they may be exposed to a high load of virus
? those whose immunity (the body's defence mechanism against infections) is affected, such as children with HIV infection, malnutrition or malignancy
? those who are vitamin A-deficient (see slide 6)
The lack of adequate health care for children with measles also increases the risk that untreated complications will progress to severe complications and ultimately to death. Even when a health centre is nearby, parents may not understand the need to bring sick children early enough, and often seek help when complications are well advanced.

Not sure where TB is coming into this now (there you go skipping about again) but I don't know how healthy your cousin is, whether she had any underlying conditions or whether the vitamins she was stuffed full of were sugar coated orange flavour things out of a plastic bottle. I don't really see how it is relevant anyway tbh - I don't think you'd approve if i started using anecdotes as proof of something. Your cousin's (very rare) TB meningitis is proof of what exactly?
