Vaccines Italic textare microbial preparations of dead or modified pathogens designed to stimulate an immune response in the body in order to prevent future infection with similar pathogens.

History:
 * Edward Jenner the first doctor to introduce and study the smallpox vaccine, although Benjamin Jesty, a farmer, earlier had vaccinated with cowpox to induce immunity to smallpox. It is believed that Jenner discovered it independently.
 * Louis Pasteur was the inventor of the process of pasteurization- the process of heating liquids in order to destroy harmful viruses and pathogens and created the first vaccine for rabies.

Types of Vaccines:

•Prophylactic vaccines: Prevent a possible future infection by any natural pathogen. •Therapeutic vaccines: The main therapeutic vaccines used are cancer vaccines.

Types of Traditional Vaccines:

1-	Vaccines containing toxoids:'' These are made by treating toxins (or poisons) produced by micro-organisms with heat or chemicals, such as formalin, to destroy their ability to cause illness. Examples: Diphtheria toxoid vaccine and Tetanus toxoid vaccine. 2-	Vaccines containing live attenuated (weakened) micro-organisms:''These organisms are cultivated under conditions that disable their virulent (disease causing) properties. Examples: Measles Vaccine, Mumps Vaccine, Rubella Vaccine, Oral polio vaccine and varicella vaccine. 3-	Vaccines containing killed micro-organisms:''These are previously virulent micro-organisms that have been killed with chemicals or heat. Examples: Inactivated polio vaccine, inactivated influenza vaccine, cholera, bubonic plague and Hepatitis A. 4-	Component Vaccines:'' Some vaccines are made by using only parts of the viruses or bacteria. These vaccines cannot cause disease, but they can stimulate the body to produce an immune response that protects against infection with the whole pathogen. Examples: Haemophilus influenzae type B (Hih) Vaccine, Hepatitis B Vaccine, Hepatitis A and Pneumoccocal conjugate vaccine.

Vaccines side effect:

•Certain vaccines have more severe side effects. However, these side effects remain very rare. •Most vaccines may cause mild problems such fever, headaches, etc.

Examples:

1-Japanese Encephalitis Vaccine: rash, swelling of the hands and feet, face, or lips; seizers and nervous system problems. 2-MMP (Measles, Mumps and Rubella) Vaccine: deafness, brain damage, long time seizers or commas. 3-Rabies Vaccine: headache, nausea, abdominal pain, muscle aches, dizziness (5% - 40%) Guillain-Barré Syndrome (GBS) and nervous system disorders (very rare). 4-Smallpox Vaccine: Serious eye infection or loss of vision due to spread of virus to the eye.

Controversy in Vacciness:

-Thimerosal: -Religion:
 * Mercury-containing thimerosal (used as a preservative in vaccines) was believed to cause autism.
 * Today, most vaccines do not contain thimerosal as a result of actions taken by the CDC Center for Disease Control. Studies have denied the claim    that there is a link between thimerosal-containing vaccines and autism.
 * The Family Research Council a conservative U.S. Christian group opposes the mandatory vaccination for diseases typically spread via sexual contact.
 * They argue that without vaccination the possibility of disease serves to discourage sexual promiscuity.
