How common is measles in the United States?
"Before the vaccine was licensed in 1963, there were an estimated 3–4 million cases each year. In the years following 1963, the number of measles cases dropped dramatically."
So, clearly we have different sources. I did not click on the first Google result like you did. The CDC has the chart you copied( but did not cite). Others sources list different data.
I stand by my figures since they are repeat here:
http://immunizationinfo.com/diseases-prevented-by-vaccines/measles/
"Measles in the USA prior to the measles vaccine was estimated to cause 4,000,000 cases per year (equivalent to the entire birth cohort in the USA); virtually every person had measles virus infection by age 20."
Also, if you read the post, rather than just trying to argue you would see this line
"However, by the early 1960's(before the Measles vaccine was used in the U.S.(1967 I believe) the death rate from measles was about 3 in 100,000 cases. "
There is a little vagary in time and statistics. But thanks for showing your lack of reading comprehension in yet another post. I was commenting to someone other than GunRunner(soi disant expert on all things vaccine related due to his immense Google skills and despite his dearth of any real expertise), so I did not dumb it down enough for you. But now that I see you are jumping in on this thread, I will try to keep it down on your level.
So, to answer your question....I did not say that the death rate in 1963 was 3 in 100,000 cases. Also, I question you 450,000 cases. These would be cases reported to the CDC(your uncited source), not the total number of cases. Other, scientific entities would have tabulated the total number of cases differently. Have a nice day!
Other, scientific entities would have tabulated the total number of cases differently.OK, well let's go strictly by your numbers, since you stand by them.
Please explain how 500 deaths in 1963 (your number), with the most liberal number of total cases (4,000,000; also your number) calculate into 3 in 100,000.
What type of math are you using? I'm getting 1 in 8,000.
