The government panel that sets U. S. vaccine policy
already has begun discussing "universal immunization" as a way to boost
vaccination rates and reduce flu-linked sickness and death, Dr. Scott Harper of
the federal Centers for Disease Control and Prevention said at a vaccine meeting
this week.
(41) ___________________
Harper
acknowledged that the recent crisis momentarily upstaged universal immunization
discussions, but said it remains a viable proposal.

___________________
The vaccine meeting, held every year, seeks
to set an agenda for the upcoming flu season. Participants many with a
financial stake in getting more people vaccinated--said the universal
vaccination push is likely to come within the next five years.
(43) ___________________
Also, flu vaccine is altered
every year because there are always different flu strains circulating. The
unused vaccine is discarded at season's end, making flu shots financially
unappealing for manufacturers.

Sanofi Pasteur's Philip Hosbach said the
company has two idle U. S. factories "because there's not the return on the
investment." Universal vaccination could in the long term help stabilize supply
if it increased demand, he said.

Demand has historically been a problem, too.
Millions of the at-risk patients routinely skip annual shots. Some people
worry the vaccine isn't safe or they simply don't like shots, but many also
underestimate the seriousness of flu, said Dr. Ann O'Malley, a researcher at the
Center for Studying Health System Change.
A. "Part of our
job is to just keep this issue on the radar screen," Harper told vaccine
providers, distributors and manufacturers at the national flu vaccine summit
here.
B. So far only one company, Sanofi Pasteur, is licensed to
make U. S. flu vaccine for the upcoming season, though public health
officials hope two others, including Chiron, will soon gain approval.
C. Estimates suggest that in an average year, flu infects about 82 million
people nationwide, hospitalizes 200,000 and kills 36,000.
D. Dr.
Herb Young of the American Academy of Family Physicians said recommending shots
for everyone could ease the confusion--and that his group is moving toward
supporting the idea.
E. The hurdles, some observers say, are
daunting. Unstable supply is one of the biggest. This year the best case
scenario--having about 90 million shots available--isn't even enough for the 180
million high-risk people advised to get shots, let alone the total
population of 280 million.
F. The end of a chaotic season where
many people seeking flu shots were turned away because of a shortage might seem
an odd time to broach the idea of vaccinating even more people.
G. But I'ra Longini, an Emory University biostatistician who specializes
in vaccine analysis, said universal vaccination would be unworkable unless
supply problems can be resolved.
