Vaccines help a body's immune system prepare in advance to fight infectious illnesses and potentially deadly diseases caused by infectious agents or their by-products. Essentially, vaccines give the body a preview of a bacterium, virus, or toxin allowing it to learn in advance how to defend itself against that potential invader. If the body is ever infected by that particular pathogen after the vaccine has done its work, the body's immune system is ready to protect us because it has created "memory cells" when exposed to the vaccine. These cells can tell your immune system exactly what antibodies it needs to make for that particular pathogen and can get to work before the infection gets out of control.

What is the worst possible reaction to a vaccine?
The worst possible scenario is that you have an allergic reaction to the vaccin. A vaccin consists of one or more antigens injected into your body. An antigene is a "marker" of a specific virus/bacteria toxin etc.. Therefore you are not actually being injected with a "disease" of any sorts.. Just the marker of the infectious agent. Your body remembers this marker. If you are then infected with the infectious agent associated to this marker later in your life (virus, bacteria toxin etc..) your body can react alot faster and supress the infectious agent because it's already seen in before and remembered it. The Antigene injected is not at all harmeful. As i said, the worst thing that could happen is an allergic reaction to that antigene (very rare). Common reactions are a slight fever or "cold" symptons, which are just proof that your immune system is working correctly. P.s: Just a side note, some vaccins are not antigenes but suppressed toxins or viruses. This means that you ARE being injected with an infectious agent, BUT that it has been geneticly modified to cause no harm. I could say that there might be a risk that the infectious agent was not sufficiently suppressed, but that NEVER happens with all the strict procedures and tests vaccins have to go through. Hope i helped.
