The DEATH rate for SARS is 5.9 %. I don't know where you came up with 10%.
1998/99 had two types that season. 8% mortality rate. Higher than SARS. Both of my daughers were very sick with the type B. There was no flu shot for the type B that year. That was another flu that caught WHO with it's pants down, so to speak. Hubby cought it too that year. He had pneumonia for the first time in his life. He'd had a flu shot....but it was for the type A, which apparently gave no protection for the type B.
Utter nonsense. Stop and think for a moment what an 8% death rate would be for the flu, which hits 27 to 54 million American victims per year.
