Origin of AIDs

Sep 09, 2008 10:41

So I saw this documentary called " The Origin of AIDS". It hypothesizes that AIDS was spread to humans by a polio vaccine given to the Congo in the late 50's. I posted about vaccines in general in another community using this documentary as a segway and got my ass handed to me. So I thought I'd see where blackfolk sit on this subject. Maybe its ( Read more... )

From a microbiologist's perspective... espnchick1920 September 9 2008, 16:07:43 UTC
It is quite plausible. The primate version of HIV is SIV (simian immunodeficiency virus). SIV and HIV are VERY similar to each other and both have the ability to mutate rapidly to survive in their enviroments (this is well known by anyone who has been on anti-HIV medicine for a considerable length of time but has to change regiments due to the development of drug resistance by their HIV). Humans can be INFECTED with SIV but they do not develop simian AIDS (or a human version of simian AIDS) because the virus can not complete its replicative cycle within human cells. The same is true of HIV within primates, and it is why there is only ONE species out of hundreds of species of monkeys that can serve as a proper animal model for HIV/AIDS research. Now, that being said, if SIV is consistently exposed to human cells, at some point over time, it will begin to mutate so that it CAN infect and complete its replicative cycle within humans. When it can do that, it has gone from being SIV to HIV.

Now, regarding the polio vaccine...it wasn't the vaccines in and of themselves (i.e. vaccine design). They did NOT use HIV/SIV as a template to make polio vaccines so let's get THAT part straight NOW. The polio virus and HIV do not have the same target cells and they do not have the same route of transmission. The two viruses aren't even in the same family and are similar only in that they are both viruses. Therefore, there was no nefarious doctor in the lab thinking up new ways to fuck over humanity for a profit. The polio virus was and is the template for the polio vaccine. HOWEVER, the polio vaccine (at least the most effective ones) are what we call "live attentuated." This means that the genes which directly cause the disease are removed but the rest of the virus is kept intact. When dispensed, it follows the natural route of infection (which is why a number of 40-50 year olds can attest to being giving sugar cubes in school when they were children...the sugar cubes held the vaccine). Because it is LIVE, it has to be "grown" in living cells (viruses can not replicate outside of living cells) and these cells are often monkey kidney cells. The prevailing theory is that in the Congo, the monkeys that were used were infected with SIV. As the virus was harvested, the SIV was introduced into humans and began to mutate, thus becoming HIV. Either that or there was already HIV present in the monkey kidney cells so that the patients were directly given HIV with the vaccine.

As a scientist, and specifically a microbiologist, I believe that this is completely possible, even likely. However, I believe that this happened in conjunction with the wars that were occuring around the same time that were driving people into the bush and forcing them to survive by any means necessary. The hunting and skinning of monkeys, some of whom could have had SIV, could have exposed the survivors to SIV which mutated over time to become HIV.

Awwww...thank you. You have NO idea how much I needed to hear something like that right now!!!

You have the very enviable gift of being able to explain technical concepts in simple terms. Normally you egghead microbiologists scientific professionals start talking to lay people and their eyes glaze over within seconds, but this is not the case with any of the explanations you've provided me.

I say all this to say that you should never let this talent go to waste.

Thank you, sweets. You'd THINK it would be appreciated here at a university but these students are too busy bitching about the fact that I take points off even if they are five minutes late. (If I had a dollar for every time I hear "But it's only 8:05!" for a class that starts at 8:00...)

I mean...seriously...if you can figure out a way that I can use this talent more effectively (and get paid), PLEASE let me know. I feel like it is going to waste here and said talent (as often repeated by medical/dental/pharmacy students, in other words...students who actually are working towards some shit) is the reason I decided to become a professor in the first damn place...

Question, I thought HIV/SIV could not live outside of the host. How do the viruses transfer in the tissue of a chimp from a perti dish to a vaccine and then a human subject?

Also are there any accounts of people having to survive on monkey meat, I would like to read up on that?

It is not that they can not SURVIVE outside of the host. It is that they can not REPLICATE outside of a host cell. Once again, remember that the VACCINE is cultivated within monkey (not chimp...they ARE different animals) cells. If those cells/tissues are already infected with SIV/HIV, then it is possible to collect it ALONG WITH the vaccine. Remember, this was back in the 40s and 50s, therefore, they a) did not know about HIV/SIV at the time (the first documented case of HIV/AIDS was a Bantu man in 1959 but even then, that was diagnosed WELL after the fact based off reading the case history...it became more medically mainstream in the late 70s/early 80s) and b) they did not have (or think to use) the type of testing that would ensure the purity of the vaccine. It actually happened more often than folks realize in the early stages of vaccine development. There were actually hundreds of children who acquired polio because there was a batch of vaccine in which the virus was not completely killed and, therefore, children were given the actual live virus as opposed to the dead-virus vaccine. This is when the polio vaccine was created by infecting monkey cells with polio virus and then killing the entire cells with formaldehyde and injecting the formaldehyde-killed virus (and cell debris) into patients.

Now regarding having to survive on whatever is present (including monkey meat), I can not recall written accounts off the top of my head. However, I have people speak about it when they discuss their times within the bush during civil war. The next time I come across a documentary in which they discuss this, I will be sure to write the name down JUST.FOR.YOU. You have to remember that when it comes to war (particularly civil war), one the easiest ways to oppress and control people is to control their food supply. Thus cattle and livestock are often killed off for and by the enemy. Farms are burned. Additionally, who the hell has time to cultivate land and livestock when you're in the middle of a CIVIL WAR??? Why is it INCREDIBLY far-fetched for you to believe that this is a possiblity?

It's not incredibly far-fetched to believe I just wanted to read up on it.

Oh...and understand that I said that it was for SURVIVAL. I didn't say folks go off eating monkeys just to do so (although there ARE some cultures where monkeys are considered to be a delicacy...so it's a matter of cultural perspective...we eat cattle...Indians think we're fucking crazy for eating their gods and, therefore, WE'RE savages to them). No, I don't buy into Africans being savage, etc. However, we have GOT to stop thinking about what white folks think about us and our African brothers and sisters. If it is the truth...it is the truth...regardless of the spin.
