Vaccination is a crucial tool in preventing infectious diseases and saving lives. It works by teaching the immune system how to defend itself against harmful pathogens, reducing the risk of infection and helping to control the spread of diseases.
Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. This response helps the immune system recognize and fight these antigens without causing the disease.
