Super-Vaccine For Flu In Development 165
Adam9 tipped us to a DailyMail article about the possibility of a revolutionary flu vaccine that could work against all strains of the Influenza A disease. This 'holy grail' of vaccines would work on everything from the annual 'winter flu' to the 'bird flu'. The best part is that just a few vaccinations may provide complete immunity, unlike the annual boosters are current defenses require. From the article: "The new jabs would be grown in huge vats of bacterial 'soup', with just two pints of liquid providing 10,000 doses of vaccine. Current flu vaccines focus on two proteins on the surface of the virus. However, these constantly mutate in a bid to fool the immune system, making it impossible for vaccine manufacturers to keep up with the creation of each new strain. The universal vaccines focus on a different protein called M2, which has barely changed during the last 100 years."

Guess what ? I *happen* to be vaccinated [wikipedia.org] against TB. There are vaccine against TB. It isn't as widely used in the USA is it was in eastern country in the past or still today in Africa. The main reason that it is less used in the western world is that TB isn't very prevalent, and therefor, TB vaccine is only given to people at risk.
(A less important reason is also aesthetic : adults and older children may have a small permanent scar at the point of injection).
In the western world. The largest part of the patient are in third world countries. The TB is prevalent there because of poorer population and harder access to medication, lower quality of life, etc...
No, as long as there is still a source were the bacteria can proliferate they'll still be there around and still find ways to travel back to your home. There are lot of disease that are clearly under control - with both vaccine and treatment available - but that are still not extinct, because they can proliferate in some animal population (not even in another human population living somewhere else).
The main reasons why there's still TB around are mainly the economic situation in counrties where it's prevalent.
(then there also some other smaller reason like the fact that the bacteria can hide in cavities where they're less accessible to drugs, and also they can stay dormant for a long time).

TB is not totally curable - in fact we are seeing a huge increase in multi-resistant strains of this bacillus. You have to take up to 6 different antibiotics (rifampin, isoniazid, ethambutol, pyrazinamide, streptomycin and pyridoxine) and supplements during up to 6 months or more. There is poor compliance with the treatment, which makes this a disease that is very hard to cure. I would also argue that although TB and its complications might directly kill more people (the death rates are similar in the US, 0.6 per 100,000 for TB and 0,4 per 100,000 for influenza), the consequences of influenza - especially in the elderly, are usually devastating for quality of life and prognosis purposes.

There's no such thing in nature. Proteins don't "decide" to evolve, and DNA doesn't "decide" to mutate. All evolution happens because of random mutations in DNA -- random in terms of where the mutation is, what the mutation does, and when the mutation occurs -- followed by the proliferation (or not) of that mutation due to natural selection.
(There are some minor exceptions to the randomness of mutation, such as alternative mRNA splicing [wikipedia.org] and certain regions of DNA that trip up the replication process, but they can be ignored for this discussion.)
In the case of influenza [wikipedia.org], mutations happen at an extremely rapid rate: the influenza genome is made of single-stranded RNA (no backup copy) and is copied by a viral transcriptase without the aid of any proofreading enzymes (no verification happens when copies are made). This means that the average mutation rate is roughly 1 per virus, on average. That's an insane mutation rate -- moreso since the genome of any RNA virus is almost 100% genes -- and it only works because influenza creates so many copies of itself in each infected cell.
Now, not knowing anything about the M2 protein's history except for what's in the article, the fact that the M2 protein has remained nearly the same for the last 100 years -- despite all these rapid mutations -- means that the dominant M2 protein is being strongly selected for. That means that viruses with a different M2 don't spread very well, as compared to viruses with the most popular M2. This suggests that, even if a newer vaccine causes the immune system to target only the currently popular M2, the viruses that escape the vaccine will be less effective than any influenza strain of the last 100 years.
(Of course, "worse for influenza" doesn't necessarily equate to "better for humans". It could be that the reason the current M2 is so popular is that it doesn't kill as many human hosts as the older M2s, which benefits both humans and influenza. But, given what the Wikipedia article [wikipedia.org] says about M2's function, the smart money is that switching to the older M2 will impede the virus's ability to infect a cell, which is a win for humans.)

Presumably, mutations that render "anti-M2" vaccines ineffective are also possible, perhaps not necessarily in the same range of probability (one could argue that mutations are far less likely when the virus is faced with the immune system versus a drug).

M2 happens to be an ion channel protein for the flu virus, which is also necessary for propagation of the virus (it's thought to be involved breaking down the virus protein coat once inside the host cell, freeing the genetic material to be replicated). As the article notes, it tends to be more conserved than H and N- there may be a severe disadvantage for a flu virus to have a mutant strain of M2.
What the article does not mention, however, is that there are a couple of antiviral drugs already available which target M2. Amantidine [wikipedia.org] and rimantidine [wikipedia.org] both are thought to interfere with M2, and are already administered as antivirals against flu. (Curiously enough, they started as Parkinson's treatments- it was discovered patients taking them had serendipitous flu resistance). While a vaccine meant to target M2 might work differently than the adamantane-based antiviral drugs, it's worth noting that influenza, and H5N1 flu at that, resistant to those drugs is already quite common throughout Southeast Asia.
