People with healthy immune systems don't die of flu.
What about people without healthy immune systems? Is your immune system healthy, or is the way to check just to see if you die of the flu? Or maybe you get a type that kills you because you have a healthy immune system, like the 1918 pandemic, who knows.
As for the MMR vaccine causing measles, what? Before vaccinations, 90%+ of children contracted measles. Now it's down to a few hundred a year. That's a very strong correlation, but not for your theory.
