The former California state senator who helped eliminate nonmedical vaccine exemptions should use his congressional position in 2027 to demand answers about the measles crisis, federal health policy, and the future of America's public health institutions.
The election of Dr. Richard Pan to the United States House of Representatives in California's 6th Congressional District presents an opportunity to bring an important public health debate from Sacramento to Washington, D.C.
Pan, a pediatrician and former California state senator, defeated incumbent Kevin Kiley in the November 3, 2026 election, according to CBS News. His victory is significant not only because of the political change it represents in Northern California, but also because of his legislative history involving one of California's most controversial public health policies: eliminating personal-belief exemptions from childhood vaccination requirements.

As the United States faces a renewed measles crisis and significant changes to federal vaccination recommendations, Pan will enter Congress with firsthand legislative experience in addressing vaccine-preventable diseases.
In 2027, he should use that experience to demand congressional oversight of the Department of Health and Human Services (HHS), particularly Secretary Robert F. Kennedy Jr., and examine whether current federal policies are adequately protecting Americans against preventable infectious diseases.
This should not be reduced to another partisan confrontation between Democrats and Republicans. The underlying issue concerns public health, scientific accountability, childhood immunization, and the responsibility of government institutions to protect the population.
Pan has already been involved in this debate once in California. Now he has an opportunity to bring those lessons to the national stage.
The 2014–2015 measles outbreak changed California's vaccination debate
To understand why Pan's election matters, it is necessary to revisit California's measles outbreak during 2014 and 2015.
The outbreak attracted national attention after measles cases were associated with Disneyland in December 2014. The disease subsequently spread beyond the original locations, exposing vulnerabilities in communities where vaccination coverage was insufficient.
Measles is among the most contagious infectious diseases. It can spread rapidly through populations, particularly where individuals have not received the recommended vaccinations.
The problem was not simply that an infectious disease had returned. It was that communities with insufficient immunization coverage created opportunities for a disease that had previously been eliminated from continuous transmission in the United States to spread again.
California was already experiencing concerns about increasing personal-belief exemptions from childhood vaccination requirements.
Pan, who served in the California Senate and had a professional background in pediatrics, became one of the central figures in the legislative response.
He authored Senate Bill 277, legislation that eliminated personal-belief exemptions for children attending public and private schools and childcare facilities. Medical exemptions remained available.
The legislation was signed into law in 2015 and took effect in 2016.
The debate was controversial. Opponents argued that parents should retain greater authority over medical decisions involving their children, while supporters maintained that vaccination requirements were necessary to protect children and the broader community.
At the heart of the debate was an important public health principle: vaccination protects individuals, but widespread vaccination also helps protect people who cannot receive certain vaccines because of their age or medical circumstances.
The effectiveness of SB 277 has also been examined through academic research.
A peer-reviewed study published in PLOS Medicine evaluated the effects of California's policy and found that eliminating nonmedical exemptions was associated with increased childhood MMR vaccination coverage. The researchers identified improvements in vaccination coverage at both the statewide and county levels. PubMed +1
The law did not eliminate every vaccination challenge, but it demonstrated how legislation can influence childhood immunization coverage.
That experience is particularly relevant today.
America's measles crisis is becoming a national concern again
More than a decade after the Disneyland-associated outbreak, the United States is confronting another serious measles challenge.
According to the CDC's November 6, 2026 update, the country had recorded 5,182 confirmed measles cases as of November 5. This compares with 2,289 cases during all of 2025.
The CDC also reported 43 outbreaks during 2026, with 96% of confirmed cases associated with outbreaks. These figures are preliminary and subject to change. CDC
These numbers should raise serious questions about the country's ability to maintain sufficient vaccination coverage.
Measles is not a new or mysterious disease. Its transmission patterns are well understood, and an effective vaccine has been available for decades.
Yet the United States continues to experience outbreaks that place children, families, healthcare workers, and medically vulnerable populations at risk.
This is where the federal government's responsibility becomes particularly important.
HHS and the CDC have national responsibilities involving disease surveillance, vaccine recommendations, public health communication, and assistance to state and local health departments.
When federal recommendations change, Americans deserve clear explanations of the scientific evidence supporting those decisions.
The current administration has made substantial changes to childhood vaccination policy. In January 2026, the CDC accepted a revised framework that divided childhood immunizations into vaccines recommended for all children, vaccines recommended for certain higher-risk populations, and vaccines based on shared clinical decision-making. CDC Newsroom +1
An August 2026 presidential executive order further established the administration's approach to childhood vaccination recommendations and parental choice. It also addressed the use of separate vaccines rather than combination products, including MMR, when such products become available. The White House
These decisions deserve careful examination.
There is a legitimate distinction between continuously evaluating vaccine safety and changing established recommendations without sufficiently transparent scientific justification.
Public health agencies should always examine new evidence. Vaccine recommendations should be grounded in reliable research, independent expert review, and transparent assessments of risks and benefits.
However, when federal officials change established recommendations, the public deserves to understand why.
RFK Jr. should answer questions before Congress
As a new member of the House of Representatives, Pan should make congressional oversight of federal vaccine policy one of his priorities in 2027.
He should work with the appropriate congressional committees to request hearings examining the measles outbreak and the administration's broader approach to childhood vaccination.
HHS Secretary Robert F. Kennedy Jr. should be asked to explain the department's decisions and provide the scientific evidence supporting its policies.
The questions should be specific.
Why have measles cases increased so dramatically?
Are changes to federal vaccination recommendations supported by consistent scientific standards?
How have changes to federal vaccine advisory committees affected the development of national immunization recommendations?
Are federal public health agencies communicating the importance of MMR vaccination effectively?
Are state and local health departments receiving sufficient resources to respond to outbreaks?
And what is HHS doing to prevent the current measles situation from becoming an even larger national public health emergency?
These questions should not be treated as personal attacks against Kennedy.
Rather, they should be part of the ordinary congressional responsibility to investigate government decisions that have consequences for millions of Americans.
Congressional oversight should include testimony from CDC officials, independent epidemiologists, pediatricians, infectious disease specialists, state public health directors, and medical organizations.
Pan should also examine the restructuring of the Advisory Committee on Immunization Practices (ACIP), including the qualifications of its members, the transparency of its deliberations, and the scientific standards used to develop recommendations.
The American public deserves confidence that vaccine policy is being developed through rigorous and independent scientific evaluation.
As a pediatrician and former legislator who helped shape California's vaccination policy, Pan could contribute an important perspective to these proceedings.
He should also recognize the limits of his individual congressional authority. He cannot independently compel a Cabinet secretary to testify or conduct a committee subpoena investigation simply because he is a member of the House. He will need to work through the appropriate committees and build support for formal oversight.
Nevertheless, he can request hearings, raise questions, seek information, and advocate for investigations.
California's experience offers lessons for the rest of America
California's experience with SB 277 demonstrates how public policy can influence vaccination coverage.
The law did not eliminate every obstacle to vaccination, nor did it guarantee that measles outbreaks would never happen again.
However, research found that eliminating nonmedical exemptions was associated with improved childhood vaccination coverage.
That experience is relevant because the United States does not have a single, uniform vaccination system.
States establish school-entry vaccination requirements, while federal agencies provide scientific recommendations, funding, public health guidance, and assistance during infectious disease outbreaks.
This division of responsibilities makes cooperation between federal and state governments essential.
California's approach also demonstrates that public health legislation requires more than passing a law. It requires implementation, monitoring, education, access to vaccines, and the willingness to address communities where vaccination coverage remains inadequate.
Pan understands this from his experience in Sacramento.
There is also another historical connection worth examining: California's response to COVID-19.
When the coronavirus pandemic began spreading across the United States in 2020, California implemented separate public health interventions, including testing programs, emergency restrictions, vaccination campaigns, public education, and other measures intended to reduce transmission.
SB 277 was not a COVID-19 policy and did not directly slow the transmission of COVID-19. Nevertheless, California's earlier experience with childhood immunization illustrates the importance of maintaining public health infrastructure before an emergency occurs.
The COVID-19 pandemic demonstrated how quickly infectious diseases can disrupt schools, businesses, healthcare systems, and everyday life.
It also demonstrated the importance of coordination between local, state, and federal governments.
The broader lesson is that public health preparedness should not depend on which political party controls Washington.
Infectious diseases do not respect state borders or political affiliations.
A disease spreading in one state can quickly become a problem for the entire country.
My Sacramento State experience during the 2015 vaccination debate
My interest in this issue also comes from personal experience.
I was a student at California State University, Sacramento, commonly known as Sacramento State, during the 2015 period when California's vaccination legislation was being debated. I was studying Biology at the time.
I remember hearing about politicians bringing up Sacramento State's student vaccination requirements and immunization list as part of the broader public debate surrounding California's changing vaccine laws.
For me, this was more than a political discussion happening somewhere in the state legislature. It was an issue that had a connection to my own university experience and academic interests.
As a Biology student, I was interested in the relationship between infectious diseases, vaccination, public health, and the responsibilities of institutions serving large populations.
Sacramento State's current immunization policy provides a useful illustration of how these requirements operate within higher education. The university identifies measles, mumps, and rubella vaccination among its required immunizations for students, alongside other requirements. Its health services also emphasize the importance of vaccination in preventing measles transmission on college campuses. Sacramento State +1
This is an important connection because universities bring together thousands of students from different communities and backgrounds.
College campuses are places where people attend classes, share facilities, participate in activities, and interact in large groups. When an infectious disease enters such an environment, vaccination coverage becomes an important consideration.
My experience as a Sacramento State student helped make the 2015 debate more tangible to me.
I was witnessing a discussion about vaccination policy while studying a scientific discipline that examines biological systems and infectious diseases.
That experience is one reason I believe the current national discussion deserves more attention.
I am not suggesting that my personal experience establishes what happened in every legislative discussion, nor am I speaking on behalf of Sacramento State. Rather, I am explaining why this issue has remained meaningful to me and why I see a connection between California's earlier vaccination debate and the current national public health situation.
What Pan should pursue in Congress in 2027
Pan's election creates an opportunity to bring his California legislative experience into a broader national discussion.
There are several practical steps he should pursue.
First, request congressional hearings on the measles outbreak.
Congress should examine the causes of the increase in cases, the federal response, and whether vaccination coverage is declining in particularly vulnerable communities.
Second, investigate changes to federal vaccine recommendations.
The administration should explain the scientific evidence supporting its revised childhood immunization framework, including the role of independent expert review.
Third, examine the consequences of federal public health messaging.
Conflicting messages about vaccine safety and effectiveness can create confusion among families and healthcare professionals. Congress should examine whether federal communications accurately represent established scientific evidence.
Fourth, strengthen federal support for state and local health departments.
Local agencies need resources for disease surveillance, laboratory testing, vaccination programs, public education, and emergency response.
Fifth, protect access to childhood vaccinations.
The discussion should not focus exclusively on mandates. Congress should also examine barriers that prevent families from obtaining recommended vaccines, including healthcare access, transportation, insurance coverage, and the availability of vaccination services.
These proposals would allow Pan to connect his experience in California with practical federal policy.
They would also encourage an evidence-based discussion rather than turning every disagreement into a partisan confrontation.
America's public health future deserves accountability
The national vaccine debate should not become another political contest in which one side automatically defends every government decision and the other rejects every scientific recommendation.
There should be room for legitimate questions about vaccine safety, effectiveness, side effects, access, and government authority.
Parents deserve accurate information. Patients deserve transparent medical guidance. Healthcare professionals deserve confidence that federal recommendations are based on reliable evidence.
At the same time, public health decisions must recognize that individual choices can have consequences for other people.
When vaccination coverage falls sufficiently, infectious diseases have greater opportunities to spread. That risk is especially serious for infants, immunocompromised individuals, and others who cannot receive certain vaccines.
This is precisely the issue California confronted during the 2014–2015 measles outbreak.
It is also an issue that federal policymakers must confront today.
Richard Pan helped California respond to this challenge through SB 277. His election to Congress gives him an opportunity to bring that experience into the national debate.
In 2027, he should push for congressional hearings, demand transparency from HHS Secretary Robert F. Kennedy Jr., and investigate whether federal vaccination policies are adequately protecting Americans.
The purpose should not be to defend one political party or attack another. It should be to establish whether government decisions are supported by scientific evidence and whether they are protecting the public.
America has spent decades building public health institutions designed to prevent infectious diseases from becoming national emergencies.
Those institutions must remain accountable, scientifically credible, and adequately funded.
The lesson of California's measles outbreak was that preventable diseases can return when vaccination coverage becomes insufficient.
The lesson of COVID-19 was that public health preparedness and effective government coordination can become matters of national importance almost overnight.
And the lesson of the current measles crisis should be that America cannot afford to treat vaccination policy as merely another political disagreement.
Pan helped California confront this challenge once. In 2027, he should bring that experience to Congress and make sure the federal government answers a fundamental question: Are America's public health policies protecting the next generation, or are changes in federal policy putting decades of progress against preventable diseases at risk?
That is a question worth investigating, and the American public deserves clear, evidence-based answers.
