MICROANATOMY

Detailed explanation-1: -Immunizations can save your child’s life. Some diseases that once injured or killed thousands of children have been eliminated completely, and others are close to extinction – primarily due to safe and effective vaccines. Polio is one example of the great impact that vaccines have had in the United States.

Detailed explanation-2: -Another way to produce active immunity is by vaccination. Vaccines contain antigens that stimulate the immune system to produce an immune response that is often similar to that produced by the natural infection. With vaccination, however, the recipient is not subjected to the disease and its potential complications.

Detailed explanation-3: -The major advantage to passive immunity is that protection is immediate, whereas active immunity takes time (usually several weeks) to develop. However, passive immunity lasts only for a few weeks or months.
