Re: Index cases...

-please provide scientific evidence which can prove that disease reduction in any part of the world, at any point in history was attributable to inoculation of populations?

HELLO??? Smallpox?????

And how about the measles vaccination introduced in the early 1960s?

The following is a table focusing on MORBIDITY (disease incidence) from a census report at: http://www.census.gov/prod/99p...
 

Year . . Incidence rate per 100,000 of measles
1912 . . . 310.0
1920 . . . 480.5
1925 . . . 194.3
1930 . . . 340.8
1935 . . . 584.6
1940 . . . 220.7
1945 . . . 110.2
1950 . . . 210.1
1955 . . . 337.9
1960 . . . 245.4
1965 . . . 135.1
1970 . . . .23.2
1975 . . . .11.3
1980 . . . . 5.9
1985 . . . . 1.2
1990 . . . .11.2
1991 . . . . 3.8
1992 . . . . 0.9
1993 . . . . 0.1
1994 . . . . 0.4
1995 . . . . 0.1
1996 . . . . 0.2
1997 . . . . 0.1

I'll ask you... Exactly what happened in the mid-1960s? HINT: Measles vaccination was introduced! But then you'll say "What happened in 1990?" We had major measles outbreaks 1989-1990, when, prior to 1989, only one dose of measles vaccine was recommended. No vaccine is perfect and these outbreaks pointed to the need for a booster. The recommendation was then changed in 1989 by the CDC to recommend a 2-dose measles vaccine series. Please note from the table above that subsequent incident rates again dropped.
