Driving progress for the benefit of society by providing independent, objective advice to advance science, engineering, and medicine.
Statement on CDC’s Changes to Guidance on Vaccines and Autism
Statement
The Centers for Disease Control and Prevention (CDC) this week cited some of our work in new guidance related to vaccines and autism. However, the citations do not provide the greater context of the full body of work on vaccine safety that is essential for informed debate about this topic.

Register for the 2026 TRB Annual Meeting
Announcement
Registration is now open for the 105th Transportation Research Board Annual Meeting, taking place Jan. 11-15 in Washington, D.C. Don’t miss this opportunity to connect with thousands of colleagues at the world’s largest gathering of transportation professionals.

Ways we are making a difference
“There is a critical gap between the performance of machine learning [and] what we would expect in a safety-critical system,” – George Pappas, Associate Dean of Research, School of Engineering and Applied Science at University of Pennsylvania. Machine learning, a key enabler of artificial intelligence, is increasingly used for applications like self-driving cars, medical devices, and advanced robots that work near humans — all contexts where safety is of critical importance.

12,757,958 Over 12,757,958 people have engaged with our work in 2025.
7,300 Over 7,300 innovative thinkers and accomplished practitioners volunteered their time with the National Academies in 2024.

Based On Science

The National Academies
The work of the private, nonprofit National Academies is grounded in the expertise of our three academies
National Academy of Sciences
The National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, nongovernmental institution to advise the government on issues related to science and technology.
National Academy of Engineering
The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the government.
National Academy of Medicine
The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the government on medical and health issues.
