I need some of these questions answering. I will give out points if you help me.Even if you just answer one question I will be grateful. Sites = helpfu :]

How is the Bird Flu vaccine weakened?
Why is the Bird Flu vaccine made on Hen's eggs?
Why won't some antibiotics work to cure it?
Why may the animal rights activists be concerned when its is being tested?
How does the genetic material exchange?

Adv + Dis of the Governments plan to buy Tamiflu (antibiotic)

Thanks x

1.  Easy, they kill it.
2.  They take a hypodermic needle and stick it into eggs.
3.  Because antibiotics don't work on viruses.
4.  If they are, maybe we can classify them as talking fungi and use them instead.
5.  Mutation.

1. I don't know
2. Not sure
3. Anti-biotics wont work to cure it because flu is a virus, not a bacteria.
4. don't know that one either
5. It's complicated... Viruses and bacteria can pick up and incorporate stray bits of DNA into their own, yeah it's weird.

How is the Bird Flu vaccine weakened?
Well, for starters, there is no Bird Flu vaccine as of yet.  And if there were a vaccine, why'd you want to weaken the vaccine?  You'd want to weaken the infectious agents in the vaccine.  To weaken a virus, since they're non-living (unlike bacteria) you can't kill it.  Therefore, you'd either render it disabled by doing some sort of molecular modification, or you'd just cleave off all but the "recognition" portion of the virus -- the portion that activates the immunde response.

Why is the Bird Flu vaccine made on Hen's eggs?
There is no bird flu vaccine...Tamiflu is not a vaccine.  The development of a vaccine will take some time.  But, to use hen's eggs, probably because that would effectively promote viral reproduction for harvesting to make a vaccine out of it.

Why won't some antibiotics work to cure it?
As said above, antibiotics target various mechanisms of prokaryote reproduction.  Viral reproduction is a hell lot different, and therefore cannot work.

Why may the animal rights activists be concerned when its is being tested?
'Cuz they're dumbasses...Because the testing of a new vaccine will obviously cause the death of a bunch of animals.  They have to test it on something!

How does the genetic material exchange?
Oh hell this is a huge thing on its own.  To boil it down, H5N1 is a strain of the Influenza virus, which is part of the Orthomyxoviridae family.  These viruses contain negative single-stranded RNA as their genetic information.  To exchange this information, the virus has to penetrate the cell and deposite its (-)RNA.  Viral transcriptase produces +mRNA, which is able to be translated into viral proteins.  The -RNA also undergoes viral replication to +/-RNA, which is the replicative form of the genetic info.  From here, the -RNA can be synthesized, and the viral proteins and new genetic info comes together and voila, new virus.

Adv + Dis of the Governments plan to buy Tamiflu (antibiotic)
Advantages: if they plan to administer it for free...great!
Disadvantages: Tamiflu sucks balls, the government sucks balls...

Annnnnnnnd, Tamiflu is not an antibiotic!  It's an antiviral.

Thank you so much :]
It said though that the Bird Flu Vaccine has being made on this sheet I got from school. Oh well lol.
Thanks anyway :] x

Hey, my pleasure.

Interesting thing.  There isn't a bird flue vaccine as of yet, per se (as in not in the market).  However, they are in development, and as of yesterday, it got FDA approval for second-phase clinical trials.

There are several Avian Flu vaccines that are created and shipped around the world every year and they get it on the market just in time for the flu season. It is important to separate seasonal influenza from pandemic influence, independent of both sometimes emerging as avian influenza.

The vaccine is not weakened at all - that would be extremely dangerous, since it would not have such good effects anymore.

However, the virus is weakened in the creation of vaccines together with various genetic engineering.

http://www.cdc.gov/flu/about/qa/fluvaccine.htm

There are many different types of avian influenza, such as H3N2 and the infamous H5N1.

http://www.cdc.gov/ncidod/EID/vol11no10/05-0644.htm

There have been three major global influenza pandemics in the 20th century in the years 1918 (swine flu), 1956 (H3N3), 1968-9 (H3N2).
