Tuberculosis is a disease caused by germs that are spread from person to person through the air. TB usually affects the lungs, but it can also affect other parts of the body, such as the brain, the kidneys, or the spine. A person with TB can die if they do not get treatment.

Measles is a viral illness that causes a rash all over the body. It also causes a fever, runny nose and cough. While measles is almost gone from the United States, it still kills about half a million people a year around the world. Measles spread through the air by breathing, coughing or sneezing. It is so contagious that any child who is exposed to it and is not immune will probably get the disease. Two doses of vaccine are recommended with the first does given at 12-15 months of age. The second dose may be given 4 weeks after the first, but it is usually given at 4-6 years.

Mumps is best known for swelling of the cheeks and jaw that it causes, a result of inflammation of the salivary glands. Mumps also causes a fever and headache. It is usually a mild disease, but it leads to meningitis in about 1 child in 10 who get the disease. It can occasionally cause encephalitis, deafness (about 1 in 20,00 cases), or even death (about 1 in 10,00 cases).

Rubella is sometimes called German Measles or 3-day measles. It is generally a mild disease caused by the rubella virus. It usually strikes in the winter and spring, and causes a slight fever, a rash on the face and neck, and (when teenagers or adults get the disease) swollen glands in the back of the neck and arthritis-like symptoms in the joints. It is spread from person to person through the air, by coughing, sneezing or breathing. The greatest danger from rubella is to unborn babies. If a woman gets rubella in the early months of her pregnancy, there is an 80% chance that her baby will be born deaf or blind, with a damaged heart or small brain, or mentally retarded.
