The History of Vaccines explores the role of immunization in the human experience and examines its continuing contributions to public health


Pneumococcal Disease

Streptococcus pneumoniae bacteria, also called pneumococcal bacteria, are one of the leading causes of illness in young children. They can cause pneumonia, bloodstream infections, meningitis, sinusitis, and middle ear infection. More

Vaccine Development, Testing, and Regulation

Systems for developing and testing vaccines emerged after the 19th century, when many vaccines began to be used. The current system for developing, testing, and regulating vaccines developed during the 20th century as the groups involved standardized their procedures and regulations. More

Different Types of Vaccines

Vaccines are made using several different processes. They may contain live viruses that have been attenuated (weakened or altered so as not to cause illness); inactivated or killed organisms or viruses; inactivated toxins (for bacterial diseases where toxins generated by the bacteria, and not the bacteria themselves, cause illness); or merely segments of the pathogen (this includes both subunit and conjugate vaccines).

The Human Immune System and Infectious Disease

The human immune system is essential for our survival in a world full of potentially dangerous microbes. More

Jonas Salk, Albert Sabin, and Hilary Koprowski all worked on polio vaccine development. Salk's inactivated vaccine was licensed in 1955.
