Immunization drives are organized efforts to vaccinate a large number of people, often within a specific community or region. These drives aim to protect individuals from infectious diseases by providing vaccines, which help the immune system recognize and fight off pathogens. They are especially important for children, as they can prevent illnesses like measles, polio, and hepatitis. During an immunization drive, healthcare professionals set up clinics or mobile units to administer vaccines. These events often involve collaboration between government agencies, non-profit organizations, and local communities to ensure that everyone has access to necessary vaccinations. Public awareness campaigns may also accompany these drives to educate people about the benefits of vaccines and encourage participation.
