Vaccine-preventable diseases are diseases that can be prevented by the use of vaccines. Vaccines are biological preparations that provide active acquired immunity to a particular disease. They typically contain an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins.

Types of Vaccine-preventable diseases

There are several types of vaccine-preventable diseases. Some of the most common include:

• Measles
• Mumps
• Rubella
• Polio
• Hepatitis A
• Hepatitis B
• Varicella (Chickenpox)
• Influenza
• Pneumococcal disease
• Meningococcal disease
• Human Papillomavirus (HPV)
• Rotavirus
• Haemophilus influenzae type b (Hib)

Vaccination

Vaccination is the administration of a vaccine to help the immune system develop protection from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism. In stimulating the body's adaptive immunity, they help prevent sickness from an infectious disease.

Importance of Vaccination

Vaccination is a simple, safe, and effective way of protecting people against harmful diseases, before they come into contact with them. It uses your body’s natural defenses to build resistance to specific infections and makes your immune system stronger.
