Immunization Issues

Vaccines in Development

Since the vaccine against smallpox was first created in 1796 many vaccines have been developed for childhood and adult diseases. For instance, childhood immunizations in the United States protect against 11 diseases.

There are also vaccines for travelers to countries where diseases not endemic in the US are common—such as yellow fever—and vaccines for groups with a high risk of contracting diseases such as anthrax for veterinarians.

This section contains information about some of the diseases for which vaccines are being developed and the current progress in their development.
