Schar School Highly Rated for Homeland Security Graduate Education
The Schar School of Policy and Government at George Mason University has been recognized by U.S. News and World Report as having the No. 4 graduate program in the nation – and the top program in Virginia – for homeland security and emergency management in 2026. This marks the ninth year in a row that the program has ranked among the top 10 nationally.
This achievement was due in large part to the success of the Biodefense Graduate Program, led by Professor Gregory Koblentz. The program offers a range of academic options, including graduate certificates, both online and in-person Master of Science degrees in Biodefense, and a PhD in Biodefense. The program has been active for more than 20 years and has over 400 alumni working in the public, private, non-profit, and academic sectors in the United States and around the world.
The Schar School’s other graduate programs continue to excel as well. Its public policy specialty areas were among the top performers this year, with all seven of its ranked subject areas in the top 50 nationally and in the top 25 among public universities. Six subject areas ranked No. 1 in Virginia overall, and four ranked No. 1 in the Washington, D.C., region among public universities.
“As we mark the 10th anniversary of the school’s naming, these rankings speak to what the Schar School has become over the past decade: a place of real national consequence in public affairs education,” said Mark Rozell, Dean of the Schar School of Policy and Government. “From homeland security and nonprofit management to international global policy and public finance, these rankings reflect the breadth of the Schar School’s excellence and the growing national recognition of its strengths.”
The Return of Measles: Vaccine Hesitancy and the Erosion of U.S. Public Health
By: Cameron Daniel Benton
As globalization increases and societies becomes more interconnected, developing and maintaining strong public health measures is more vital than ever. However, previously eradicated diseases are reemerging in the United States due to vaccine hesitancy and shifting policies under the current presidential administration. The 2025 measles outbreak in West Texas serves as a warning sign of what may follow if the nation continues to neglect preventable diseases. The 2025 West Texas measles outbreak has spread to neighboring states, Mexico, and Canadai and represents a risk to immunocompromised individuals and, in rare cases, to vaccinated individuals through breakthrough infections. ii
The Trump Administration is actively pivoting away from established, scientific-based evidence and towards dubious alternatives. This shift has damaging implications for local communities that rely on scientific guidance from medical professionals. For example, during the 2025 measles outbreak, Health and Human Services Secretary Robert F. Kennedy Jr., a known vaccine skeptic, initially downplayed the severity of the crisis, misleadingly suggested that vitamin A prevents measles, and directed the Centers for Disease Control and Prevention (CDC) to distribute additional vitamin A to the Texas Department of Health. iii As a result, some children were hospitalized with both vitamin A toxicity and measles.iv Although Secretary Kennedy later admitted in a Fox News op-ed that the MMR vaccine is “crucial to avoiding potentially deadly disease,”v the conflicting messages from senior government officials contribute to ongoing vaccine hesitancy.
Vaccine hesitancy is one of several factors for parents to forego life-saving vaccines for easily preventable diseases such as measles. A May 2023 study highlights various social factors, such as misinformation, low trust, and limited perception of personal risk and susceptibility to measles, vi as major drivers of the decline in MMR vaccination rates. The Atlantic interviewed Peter (no last name provided), whose daughter passed away during the 2025 outbreak, which was the first measles-related death in the United States in a decade. Peter remarked that “[measles] is not so new for us” and “everybody has it” since his grandparents and parents had it. He also said that “the vaccination has stuff that we don’t trust.” vii As the vaccination rates and trust in vaccines decrease, children will become more susceptible to otherwise preventable diseases.
Meanwhile, Dr. Ralph Abraham, the CDC’s Principal Deputy Director, recently said that the uptick in measles cases is “just the cost of doing business with our borders being somewhat porous for global and international travel.” He also emphasized the “personal freedom” of communities that choose to remain unvaccinated.viii This attitude towards measles demonstrates a shift in focus from robust, proactive public health measures to a more reactive approach. Trust in the government will likely decline as the American public perceives low prioritization of preventable disease outbreaks. Continued measles outbreaks will likely disrupt childhood education, become more common throughout the country, and become deadlier.
The current administration is reversing policy on vaccine safety through more than just public messaging, which is reflected in the data the CDC tracks in the United States. A recent study tracked how certain CDC databases had “unexplained pauses” in their updates. As of October 28th, 2025, 38 (46%) of these databases were paused, and of these, 33 (87%) were related to vaccine monitoring. 34 of the paused databases were not updated within 6 months of the study. These long pauses jeopardize the evidence that public health officials, scientists, government officials, and medical professionals use when evaluating information. The lack of transparency around the pauses further contributes to the decline in public trust.
In 2025, Secretary Kennedy unilaterally fired the entire board of the CDC’s Advisory Committee on Immunization Practices (ACIP)ix and reduced the recommended childhood vaccine schedule from 17 to 11 vaccines, citing concerns that children receive “too many” vaccines.x These actions align with the administration’s overall indifference towards vaccines and public health. In response, 28 states rejected the revised guidelines and continue to follow recommendations from the American Academy of Pediatrics.xi As parents continue to forgo the MMR vaccine, we may someday see the return of mumps and rubella in the United States. Conflicting vaccine information from two respected scientific agencies will very likely deepen the public’s distrust regarding new recommendations.
Secretary Kennedy’s restructuring and dismantling efforts of various health departments do not exist in a vacuum and align with President Trump’s transactional view of domestic and international politics. On January 22, 2026, the Trump Administration recently completed the United States’ withdrawal from the World Health Organization (WHO). This withdrawal happened exactly one year after President Trump signed an executive order to initiate the withdrawal process. xii While the long-term effects remain to be seen, the WHO has now lost major funding for various initiatives to combat and monitor various diseases.
These new public health policies also have negative financial and economic impacts during outbreaks. When children are sick with measles, parents often need to take time off work, pull children out of school, take them to the hospital or urgent care, spend money on medicine, and their jobs lose productivity. State and federal officials also spend valuable resources managing outbreaks, establishing contact tracing, utilizing diagnostics, and initiating emergency responses. xiii Researchers estimate the 2019 measles outbreak in Washington state, for example, cost approximately $3.4 million for 71 measles cases, illustrating how reactive response efforts to preventable diseases generate disproportionate financial strain. xiv
South Carolina’s Department of Public Health has reported 977 cases of measles in Spartanburg County as of April 3rd 2026,xv Utah’s Department of Health and Human Services reported 362 casesxvi and Virginia confirmed five cases as of April 1st, 2026. xvii As of April 2nd 2026, the CDC reported 1,671 confirmed cases of measles within 33 different jurisdictions in the United States. xviii The actual number of measles cases are likely underreported due to a lag in reported cases, people not going to the clinic, and the CDC’s shutdown of many centralized health databases. xix As measles continues to spread throughout the country, the Trump Administration can take steps to ensure the public remains healthy, children are protected, and the economy remains stable. The administration, state, and local government officials should invest in measles-related diagnostic kits, training for healthcare workers, and temporarily increase MMR vaccine production. President Trump can also sign new executive orders directing artificial intelligence (AI) companies to shift efforts toward medical research and pharmaceutical production. This will ensure Americans remain healthy, make the U.S. competitive in global markets, and stimulate the economy with positive, tangible, and healthy outcomes. Scientists and public health officials should coordinate, establish, and maintain decentralized health databases to monitor disease reports and track data trends. xx This will reduce dependency on the federal government and enhance accessibility.

Thirty Years of the Chemical Weapons Convention (CWC): Histories, Achievements, Challenges
The new open-access volume, Thirty Years of the Chemical Weapons Convention (CWC): Histories, Achievements, and Challenges, provides a timely assessment of one of the most successful arms control regimes, the Chemical Weapons Convention, while highlighting growing stressors relevant to biodefense. The CWC oversaw the verified destruction of the most declared stockpiles of chemical weapons in 2023 and established a robust inspection system through its implementation body – the Organization for the Prohibition of Chemical Weapons (OPCW) based in The Hague, Netherlands.
To mark the 30th anniversary of the CWC, contributors organized a conference Thirty Years of Chemical Weapons Convention (CWC): Histories, Achievements, Challenges,” held in Berlin on October 5-6, 2023. This meeting aimed to obtain fresh perspectives from various stakeholders on where we are regarding the implementation of the CWC. It also reflected on the history and achievements of the CWC over the past thirty years and explored existing and future challenges as the world prepares for new geopolitical and security environments amid ongoing challenges in volatile regions such as Eastern Europe and the Middle East. In particular, the conference also addressed the question of whether the CWC can serve as a model for the abolition of nuclear weapons.

NEW: Managing the Challenges of North Korean Nuclear/Missile Threats
From HKS Belfer Center for Science and International Affairs: “On April 13, join us in welcoming Vann H. Van Diepen, Principle Deputy Assistant Secretary, Bureau of International Security and Nonproliferation.”
“This presentation will examine the most strategically significant advances in North Korea’s nuclear and missile capabilities and assess how these developments are reshaping Pyongyang’s doctrine, including a potential shift from a retaliatory deterrent toward a more integrated warfighting posture and a lowered threshold for use under a “pre-empting pre-emption” logic. It will explore the range of strategic and operational options these capabilities enable, as well as the risks of escalation stemming from the regime’s designation of South Korea as the “most hostile state.” Situating these dynamics within the broader geopolitical landscape, the talk will analyze how deepening ties with Russia and shifting relations with China may be influencing North Korea’s force development and strategic calculus. It will conclude with an evaluation of key policy alternatives—including deterrence adaptations, arms control and “freeze” proposals, and changes to the regional security architecture—to address the evolving nuclear and missile challenge.”
