Question

How is natural immunity different from acquired immunity?​

Answer 1

• Natural immunity is inherited or transferred from parents to offspring. It is an immunity that is acquired at birth.

• On the other hand, acquired immunity is achieved by the following ways:  
• 1. By inoculation: This mainly happens when a person comes in contact of germs. Diseases like typhoid, diphtheria, tuberculosis, measles are caused this way.                                                                                                                        
• 2. When a person falls sick once: After a person falls sick of any particular disease, the antibodies of particular disease is produced in the body. So the chances of falling sick of that particular disease becomes low.
