  Hey there! 👋
  
  💉 What Is the Role of a Vaccine?
  
  A vaccine trains your immune system to fight specific diseases before you get infected. 🦠🛡️
  
  🔍 How It Works:
  
  A vaccine contains weakened or inactive parts of a germ (like a virus or bacteria).
  
  Your immune system sees it as a threat and builds defenses (antibodies 🧪).
  
  If you later meet the real germ, your body is ready to fight it fast! 💪
  
  📘 According to Science:
  Vaccines prevent illness, reduce spread, and save lives.
  
  ✅ Summary:
  A vaccine prepares your body in advance to protect you from serious diseases. It’s like giving your immune system a practice match! 🎯💉

  Vaccines are typically harmless version of the disease causing organism eg viruses and bacteria. When vaccines are introduced in the body they trigger the immune system to produce antibodies that fight the disease. This way the body learns how to fight that infections should it occur in future.
