wrong lesson (#19)
I'd like to have the last part about eliminating viruses from the planetwithout having to listen to the whole lessonIs there a software to cut these videos ?
life expectancy curves (cause) http://magictour.free.fr/panflu/usdeath.JPG
herd immunity % threshold–> no outbreak in areas with smaller population densitynot existing = better than immune ?!
doesn't seem to work this way
[25min through, from 63]
it omehow seems to depend, how it's downloaded.Sometimes I can switch forward sometimes not.seems that VRR is pessimistic about eradication….
eradicate flu ?eradicate it (flu-A) in birds –> no more pandemics
create a mild or asymptomatic flu and let it outcrowd other strainsin an artificial pandemic
one day we may create universal flu vaccineone day we may upload epitopes directly to the immune systemone day we may create cheap antibodiesone day we may create virus-eating machines (nanotech ?)or connect the immune-system to a computer-chip
Yes, you can edit the videos. What are you using, pc, mac, linux?
I don't see how you could eradicate influenza in all the animalreservoirs. Birds are the main one; you could not possibly find allthe infected ones. And if you did, and eliminated the infection,perhaps the virus in other animals would fill the void. At least withtoday's technology, eradication of influenza is impossible. But I'mtraining tomorrow's virologists who might have better tools.
“impossible” usually means : we need more money for that …
create a new human virus, which causes very mild disease and is more fit than current virusesFind it through extensive testing and reassortments in the lab or by computer-simulationor whatever.Use this new manmade virus as a living,replicating vaccine, attach epitopes to it fromother viruses against which we want immunity.Whenever an epidemic wave threatens, generate a counter-(mild)epidemic with this virus to create protection.Equip it with immunity evasion = variable envelopes.With our knowledge we should be able to create “better” viruses than nature can.
nice theme. but it takes a while to load
