Vaccine Preventable Diseases

Vaccine Preventable Diseases

Vaccination is one of the greatest public health achievements
of the 20th century. Most vaccine preventable diseases are at
record lows in the United States, but that does not mean these diseases have disappeared. Many of the viruses and bacteria are still circulating or are only an international flight away.

In 2002, the United States had 9,771 cases of Pertussis, this was the highest number of cases since 1964. Many of these vaccine preventable disease, could begin to rise if we do not continue to immunize. It is important that children and adults receive recommended immunizations on time!

The table below shows the dramatic reduction in disease that vaccines have made.
