No, I am not going to write anything either about how flu vaccine will be available for US citizens, or that there are delays in its delievery.
People, open your eyes. you don't need a flu vaccine.
If your immune system is already weak, this shot will only give your body unnecessary work.
Your immune sistem will only strain for nothing. The shot might protect you only from a few probable stamms of influenza. But we don't know which ones will actually come.
Unless (conspirologist mode on) someone evil will release "proper" influenza to start next flu season (conspirologist mode off).
By getting a flu shot you may protect you for a short period against some influenza stamms. This is uncertain. What is certain that you will contribute to pharma corporations' profit.
