The history of penicillin follows observations and discoveries of evidence of antibiotic activity of the mould Penicillium that led to the development of penicillins that became the first widely used antibiotics. Following the production of a relatively pure compound in 1942, penicillin was the first naturally-derived antibiotic.
It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. [1] [2] They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity.

Doses higher than 500 mg are not fully effective because of poor absorption. It is used for the same bacterial infections as those of penicillin G and is the most widely used form of penicillin. [34] However, it is not used for diseases, such as endocarditis, where high blood levels of penicillin are required.
Rarely, people can have reactions to the vaccine if they are allergic to certain types of antibiotics, such as streptomycin, polymyxin B or neomycin. Different types of polio vaccines
Production of antibiotics is a naturally occurring event, that thanks to advances in science can now be replicated and improved upon in laboratory settings. Due to the discovery of penicillin by Alexander Fleming, and the efforts of Florey and Chain in 1938, large-scale, pharmaceutical production of antibiotics has been made possible.
