This is the point I was making. Perhaps I should have been more explicit.
Flu mutates faster than almost anything else apart from AIDS.
Relying only on an Vaccine "in the works" would be incredibly dumb.
Apart from anything else vaccines are no magic bullet - we have had vaccines for diseases like Mumps for years but they are far from erradicated.
Remember too that Tamiflu and Relenza are generic anti-virus agents..
If something like the bird flu cross-over were to happen or even another unaticipated pandemic these would be very very handy to have.

Rov, just for clarity.
Tamiflu - neuraminidase inhibitor - can prevent influenza A or B infection in those uninfected, can mediate the effects/symptoms of a flu infection, and can aid in preventing the spread of infection.
Tamiflu is a generic anti viral medicine.Its main purpose is both mediating the symptoms/effects, thus indirectly reducing any severe or even life threatening events, and retarding the spread of a virus throughout the population.
A vaccine is NOT antibodies to the virus - its is ( in this case at least ) components of the virus itself, diluted and attenuated.
When injected into the body,it stimulates that persons immune system to produce antibodies to those specific components, and hence the relevant flu strain.
There are problems however - we still do not know how well the components will thrive in eggs ( which is how the virus particles that will comprise the vaccine is multiplied), so we still dont know what sort of yield and hence quantity of vaccine we will get.
Neither do we know as yet how many injections will be required to induce the immune response - It most probably will be one, but it could require 2 shots.
And finally, as others have already commented, it is possible the strain will mutate, and so the components selected may not be so specific.
So, it is very optimistic to say that the vaccine will be ready in 3 months.
That is another very good reason for Tamiflu - to slow the spread of the infection down whilst the appropriate vaccine is completed.
Finally, the other reason we were so well stockpiled with Tamiflu was not specifically because of the swine flu pandemic, but in response to previous and potentially far more deadly scares, such as SARS and bird flu.

Tamiflu has been given to sufferers and maybe their immediate contacts but the virus has continued to spread. Therefore to stop a full blown epidemic it needs to be administered to those not having the disease and of course the whole population.
The virus has not yet mutated even though it started in Mexico and is now prevalent throughout the world. If vaccines were that unreliable the yearly flu jab would not take place.
The only solution therefore is to keep tabs on the virus structure, produce enough vaccine and get the population especially the caring professions done as soon as possible.

The premature baby born to this poor woman has now died.
