What happens when you not vaccinated?

In a paragraph help me plz.

Well, its simply really. If your not vaccianted yet, you will develop a higher risk of getting effected by the virus your trying to prevent. However, people who are vaccinated are safe and are less likely to develop harsh symptoms but can still get the virus, all though the symptoms will be minor.
