Vaccine ProblemsVaccine Problems►These preventions are not as efficient These preventions are not as efficient

as a vaccination. as a vaccination. ►Vaccines are currently being made Vaccines are currently being made

available for the avian influenza, but it available for the avian influenza, but it is made for present day flu strains is made for present day flu strains which will mutate eventually. which will mutate eventually.

►Then a new vaccine will have to be Then a new vaccine will have to be mademade

Can not make Can not make enough enough

►We still depend on eggs to make our flu We still depend on eggs to make our flu vaccinesvaccines

► 900 million doses of vaccine can be 900 million doses of vaccine can be produced every 6 monthsproduced every 6 months Because this virus is new to our body we Because this virus is new to our body we

will need 2 doseswill need 2 doses Way around this is to add a strong boost of Way around this is to add a strong boost of

a chemical called adjuvanta chemical called adjuvant►But not enough research has been developed to But not enough research has been developed to

know how much dosage a person would have to know how much dosage a person would have to taketake

DistributionDistribution

►Avian Influenza companies have not Avian Influenza companies have not worked out how they are going to worked out how they are going to distribute the vaccinedistribute the vaccine Too many big orders from different Too many big orders from different

countries countries manufactures do not know what country manufactures do not know what country

to give the vaccination to firstto give the vaccination to first Some orders may never be fulfilled Some orders may never be fulfilled

because the vaccine is in such demandbecause the vaccine is in such demand

Distribution cont.Distribution cont.

►Rich countries will have much less Rich countries will have much less scarcity than the poor countriesscarcity than the poor countries

►70% of the worlds manufacturing 70% of the worlds manufacturing capacity is in five countries in Western capacity is in five countries in Western EuropeEurope These countries might be reluctant to These countries might be reluctant to

share with out making sure that their share with out making sure that their country first has an adequate amountcountry first has an adequate amount

Will Scientist be able to find an Will Scientist be able to find an efficient vaccine?efficient vaccine?

► If no efficient If no efficient vaccine is made vaccine is made experts say that experts say that when the virus when the virus strain changes that strain changes that there will be 25 there will be 25 million hospital million hospital admissions and up admissions and up to 7 million global to 7 million global deaths will happendeaths will happen

ConclusionConclusion

►Bird Flu is a serious virus and should Bird Flu is a serious virus and should not be overlookednot be overlooked

►The virus will spread fastThe virus will spread fast►Despite all of the efforts we make to Despite all of the efforts we make to

prevent avian influenza if there is no prevent avian influenza if there is no efficient vaccine made than millions efficient vaccine made than millions will diewill die
