Flu vaccine effectiveness from the CDC from the CDC web site at
https://www.cdc.gov/flu/vaccines-work/2018-2019.html and the corresponding paper at
https://academic.oup.com/jid/article/221/1/8/5609441
I'm trying to make sense of the numbers. Statistics can be interpreted subjectively by people.
My interpretation:
-Total flu cases=2763
-Of the 2763, the number that were vaccinated for the flu = 1316
My initial conclusion:
-Nearly half of the people who have the flu (1316/2763) had the flu shot.
-We do not have number as to how many who were not vaccinated did not get the flu. This would be a very interesting number to have.
Do my interpretations and conclusions stand scrutiny?
Assumptions:
All people with flu have sought medical help.
