Interesting, but short news story about the "Canadian problem", where "people who receive flu vaccines year after year can sometimes show reduced protection". And "seasonal flu vaccination almost doubled the risk of infection with pandemic flu."

Says the issue is "imperfect vaccines" intended for "a moving target of strains".

Yes, flu mutates, which makes the kind of vaccines we produce today an annual best guess. Changing that requires the development of a more 'universal' vaccine which would work against some aspect of the flu surface proteins which doesn't change, or changes much more slowly (or 'conserved'), as the flu mutates and hopefully is present in all flu strains.

Today's vaccines work by attempting to recognize the head of a mushroom-shaped protein on the flu's surface as opposed to its stem. The head portion of the protein mutates at a faster rate then the stem making it the target of a lot of 'universal' flu vaccine research.
