And why is it that some vaccines last a lifetime but others only a couple of years? It seems its very much an art form.
And if the reason why we don't become immune to the common cold is because the virus mutates so fast, why does it not mutate also into a different or more severe disease instead of staying the 'same old common cold"?
YOU have NEVER dumbfounded me.
The reason for my "HUH?" comment to your previous reply was because it made NO SENSE.
Therefore, it was dumb.
