First Cancer Vaccine Produced
notestein writes "Scientists have produced a vaccine that is 100% effective against the virus that causes practically all forms of cervical cancer. In the US Pap smear tests have reduced the 13,000 new cases of cervical cancer each year to only 4,100 deaths. Still, worldwide, 258,000 women died from cervical cancer last year. The same article also mentions that a vaccine that is 75% effective in protecting women against herpes has been tested."
How many more of these sort of discoveries will we have made?
I just read that the AD-36 virus and related variants have been shown to be a contributing factor in 30% of the obesity in the world. Now I see this article on Cancer.
Wild. How many of our daily problems are caused by these little rna splicing machines we call viruses?
Makes you think. I just hope that this is well tested enough for my daughter to use it in 10 or 15 years.

But few cancers are caused by viruses, and most cancers are invisible to your immune system, assuming it is working properly (e.g., not HIV, which does pave the way for Karposi's sarcoma). If the cancers themeselves were detectable, the immune system would destroy the tumor. The HPV vaccine primes the immune system to attack the traces of the virus (unless I'm mistaken).
As an aside, one of the big mysteries about HIV has been why the immune system doesn't simple kill it. It can do so to a certain extent, but HIV has the sinister strategy of infecting the immune system iteself, hiding out in T-cell. Interesting and evil.
This isn't a vaccine for cancer, it's a vaccine for the virus that leads to most cases of cervical cancer, HPV. Other cancers, heck even this type of cancer, are not helped by using this vaccine. It's only if you get it before you've contracted the virus, I'm guessing, that it's even effective. This is a long, long way from developing something that can remove/cure cancer 100% effectively.

First cancer vaccine? No longer can anyone say "you slashdotters are screwing with $NEW_TECH when you should be developing a vaccine for cancer!" Time to get back to screwing around, because someone else did the job.
This is a VIRUS story, not a CANCER story. It's only incidental that this particular virus causes one type of cancer. If it were a CANCER story, it would mean that further development of the vaccine could someday also prevent other kinds of cancer, but it won't. It might someday prevent other kinds of VIRUS induced diseases, which is of course still a very useful thing, since our expertise with viruses is negligible compared to bacteria.
If you read the story, you will see the following:
"Although there are more than 30 types of HPV that can infect human beings, one of them -- type 16 -- is responsible for about half of all cervical cancers. The experimental vaccine, made by Merck Research Laboratories, protected only against that one, although future formulations are likely to also protect against the less common HPV types that can cause cervical cancer" So although it is very good news, it does not protect against "the" virus that causes cervical cancer, it protects against the variant of that virus that causes 50% of virus derived cervical cancer. No small feat and better things to come, but not what it says in the Article lead.

I have heard some theories that the majority of cancers not already known to be caused by other agents (radiation, smoking etc) are caused by viruses. The fact is that most viruses go undetected because generally you have to develop a test specifically for a particular virus to detect it easily. So its somewhat difficult to prove one way or the other.

The chances that all or most cancers are viral [is] small; I think the current estimate is something like 1/6
If I may, this is a bit of an odd stastic: "The chances that all or most are caused by a virus". I am curious as to how that would be determined, and as to whether you are mistaken.
Some quick reading reveals that quite a few famous cancers are virus related. Leukemia for example is caused by a virus.
Hepatitis B - liver
Hepatitis C - liver
HTLV-1 - leukimia
HPV - Uterine & cervix
Epstein-Barr - Burkitt's lymphoma, nasopharynx,
Hodgkin's disease
