2. IMMUNIZATION
Immunization:
Immunization, also known as vaccination,
is the process of administering a vaccine
to stimulate the body’s immune system to
develop immunity to a specific infectious
disease. This helps prevent future
infection or reduces the severity of the
disease if contracted.
3. Why Immunization Is Important?
• Disease Prevention:
Immunization protects individuals from serious
diseases by helping their immune systems
recognize and fight off harmful pathogens, such
as viruses and bacteria.
• Community Protection:
Vaccination contributes to herd immunity, which
occurs when a high percentage of the population
is immunized against a disease. This helps
prevent outbreaks and protects those who cannot
be vaccinated due to medical reasons or age.
4. Conti.....
• Public Health Impact:
Vaccination has led to the eradication or
significant reduction of many deadly diseases,
such as smallpox and polio, resulting in
improved public health and quality of life
worldwide.
• Cost-effectiveness:
Immunization is a cost-effective public health
intervention, as it helps reduce healthcare
expenses associated with treating vaccine-
preventable diseases and their complications.
5. Common & Mild Side Effects Of
Immunization
• Pain or Swelling:
Pain or swelling at the injection site is common
and usually temporary.
• Mild Fever:
Some individuals may experience a mild fever or
slight increase in body temperature after

6. • Redness or Irritation:
Redness or irritation at the injection site can
occur, which is typically temporary.
