The CDC is changing the flu vaccine for the next season. Without
specifically saying
so, I believe it is an admission that the vaccine used for the season just
ending did
not have the right types, which explains the extensive outbreak among those
who
were vaccinated. Because of the ability of the flu virus just to change even
slightly
and thus render the vaccine ineffective, I wonder if people who have a strong
immune
system should avoid the vaccine since the vaccine may weaken the immune system
response to a strain which is only slightly different than one that the
vaccine was
intended for. Something to think about. This would not apply to vaccines
for viruses
that do not mutate so readily.
