How do they make a vaccine anyway? First, isn't the flu caused by a virus,which you can't defend against much anyway, and there are so many viruses, which one do they pick? Do they give you a live one, thus giving you the flu in the first place? Then it mutates, so the vaccine is useless. Some vaccines may work, and some may not. But you can get a useless dose of mercury and whatever brew they have mixed up in it and make some drug company rich. Just frequent hand washing is the most advised best method.
Very true. Hand-washing and staying away from sick people.
Actually, frequent hand washing with antibacterial soap can be bad for you. The 1% of bacteria that aren't killed, have a resistance to the soap, and they will grow with impunity. Make sure you wash with regular soap.
