Answer:

VACCINATION: Vaccination is the administration of a vaccine to help the immune system develop protection from a disease. Vaccines contain a microorganism in a weakened or killed state, or proteins or toxins from the organism. In stimulating the body's adaptive immunity, they help prevent sickness from an infectious disease.

Penicillin

Discovered By :

Alexander Fleming

Answer:

A1 Vaccination: Injection of a killed microbe in order to stimulate the immune system against the microbe, thereby preventing disease. Vaccinations, or immunizations, work by stimulating the immune system, the natural disease-fighting system of the body. The healthy immune system is able to recognize invading bacteria and viruses and produce substances (antibodies) to destroy or disable them. Immunizations prepare the immune system to ward off a disease. To immunize against viral diseases, the virus used in the vaccine has been weakened or killed. To only immunize against bacterial diseases, it is generally possible to use a small portion of the dead bacteria to stimulate the formation of antibodies against the whole bacteria. In addition to the initial immunization process, it has been found that the effectiveness of immunizations can be improved by periodic repeat injections or "boosters." Also see Vaccines (in the plural) and Vaccine of a specific type (such Vaccine, Polio).

A2 Designated November 19, 1999, at the Alexander Fleming Laboratory Museum in London, U.K. Also recognized at the U.S. Department of Agriculture National Center for Agricultural Utilization Research in Peoria, Ill., and the five American pharmaceutical companies that contributed to penicillin production research during WWII: Abbott Laboratories, Lederle Laboratories (now Pfizer, Inc.), Merck & Co., Inc., Chas. Pfizer & Co. Inc. (now Pfizer, Inc.) and E.R. Squibb & Sons (now Bristol-Myers Squibb Company).

The introduction of penicillin in the 1940s, which began the era of antibiotics, has been recognized as one of the greatest advances in therapeutic medicine. The discovery of penicillin and the initial recognition of its therapeutic potential occurred in the United Kingdom, but, due to World War II, the United States played the major role in developing large-scale production of the drug, thus making a life-saving substance in limited supply into a widely available medicine.

The first inventor of antibiotic is Sir Alexander Fleming.
