I used to say the same thing, Amos, I was proud of my strong immunity. I'd been a schoolteacher all my life, and the exposure to germs had given me superb resistance to almost every infectious illness. I was never ill, and scorned any kind of immunisation. Then... I grew older and my immunity became weaker, and one winter I had a terrible bout of flu. I was hallucinationg, raging fever, delirious and the doc was considering hospitalisation. After it retreated, I was like jelly for weeks, stuck indoors and feeble to the point of bedridden. It honestly took me months to get back on top. Stupidly, I still held out against the jab, but a second performance of much the same thing another year convinced me. I had the injection and since then haven't looked back. It's not just the flu, it's the attendant complications, pneumonia, M.E., and all the rest. I'd advise anyone to swallow their pride and go for it.
