*The yearly flu shot is just that, a shot. It is not a vaccine because it is different each year. Sometimes it works and other times it does not.*
Are you freakin’ kidding me ? That’s the most idiotic thing I’ve read on FR today. Just what do you think is in that shot ?
A VACCINE !!!! Pull your head out and get an education. Please.
May God help this planet.

A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body’s immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. Vaccines can be prophylactic (to prevent or ameliorate the effects of a future infection by a natural or “wild” pathogen), or therapeutic (e.g., vaccines against cancer, which are being investigated).[1][2][3][4]
