Boulder Q: If a person gets the flu, do they become immune at all to the flu? Why is it necessary to continually get flu shots?

It wouldnt be if this werent among the most mercurial of viruses; it changes virtually from person to person by random mutation (drift) and it also can exchange huge hunks of DNA with another flu virus all at once (shift). So this years virus may be only slightly related to last years and you need a new shot. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
