COMMENT: How long is someone protected from subsequent infections with mutated strains?


Submitted by Brant Goode Active Panelist  on 12/5/07 10:38 AM

What I've heard is that there is some relative protection, but it is not absolute. Flu is a tough bug, but having natural infection with one year's seasonal flu does appear to offer some protection against related strains, but not against those not related.

When a new or pandemic strain emerges, some drift mutations will of course occur, and there may indeed be some protection against subsequent strains. How much? I wish we could say.
