Sulfa drugs are prescribed to treat diseases like pneumonia, meningitis and flu. Flu is short for influenza. Some drugs prevent diseases. These drugs may be vaccines, antiserums or globulins. Vaccines A vaccine causes the body to produce substances called antibodies.
Antibodies travel through the bloodstream and fight a particular disease.
The body then builds up resistance to this disease. Vaccines have been used to fight diseases like polio, hepatitis, cholera, measles, mumps and smallpox. Antiserums and Globulins Antiserums and globulins also prevent diseases. These medications contain antibodies. This means that they act more quickly than vaccines in fighting diseases.
