I've had pneumonia. It knocked me off my tushie for two weeks. I was in excellent health when I became ill, this was eleven years ago. Last month I had the Prevnar-13 shot. Because I have Type II diabetes my immune system isn't the best. I'm not trying to lecture you but what the he-double hockey sticks were you doing on a plane??? Do you realized how many people you exposed your germs too? Also to note; don't the gate agents notice you were too sick to fly? You need to be in bed and on antibiotics.
