How Vaccines Work: A Step-By-Step Guide

Ever wonder how vaccines protect you? With so much misinformation out there, it’s important to know the facts about immunizations. This step-by-step guide will show you how vaccines prepare your immune system to prevent illness.

Step 1:

Various vaccines contain different forms of germs. The vaccines can have a weak version of the live virus, an inactive version of the virus, weakened toxins (also known as toxoids), or a specific part of the germ instead of the whole thing. These injections are not strong enough to give you the actual disease, but instead, they help teach your body how to interact with the active form of the germ should you come into contact with it.
