The goal of vaccines is to greatly reduce the complications caused by childhood diseases. Although some diseases might be good for us to catch and leave us stronger, others cause more harm than good and leave us weaker. Vaccines prepare our bodies to fight against harmful diseases that we are likely to encounter in the world.
To understand how vaccines work, imagine that your immune system is a dictionary. For every substance that your body encounters, the immune system records a definition and an action. The definition is the description of the substance. The action tells the body what to do with the substance, like absorb it or attack it.
But, before your body knows what to do with something, it must identify the substance first. The way your body identifies something is based on the shapes found on the surface of that thing. These shapes are called antigens—physical characteristics of an object that the immune system can recognize. Vaccines help your body identify what infections look like so that the immune system can use its natural defenses to treat them.
For example, imagine a child eating a strawberry. It is important that the immune system has identified the strawberry as food and absorbs it. Now imagine a child who catches a cold. It is important that the immune system has identified the cold as harmful and attacks it. Vaccines don’t change how your body acts when it encounters something; they just help your body identify what it encountered.

Vaccines teach our immune systems to fight diseases that otherwise would take them too long to recognize as harmful.</u></h2>

Gestalt psychology
Explanation:
Gestalt psychology is a school of psychological thoughts which emerged in Germany and Austria. This school has lead to the development and understanding of perception and sensation.
