Oregon Faces Measles Outbreak as Vaccine Exemptions Hit Record High
PORTLAND, Ore. — oregon is grappling with its largest measles outbreak since the early 1990s, a crisis fueled by a record number of parents opting out of vaccinating their children. According to the Oregon health Authority, 9% of kindergartener families sought exemptions from one or more required vaccines last school year—the highest rate ever recorded in the state.
This alarming trend coincides with a surge in measles cases, all of which involve unvaccinated individuals.While the U.S. declared endemic measles eliminated in 2000, the disease continues to be imported, and prolonged outbreaks in 2019 threatened the nation’s measles elimination status.The Centers for Disease Control and Prevention (CDC) has underscored the critical role of vaccination, especially before international travel, in preventing measles importations into U.S. communities. From January 2020 to March 2024, the CDC documented 338 measles cases in the U.S., with 29% occurring in the first quarter of 2024.Nearly all cases involved unvaccinated individuals or those with unknown vaccination status.
Both the CDC and the World Health Organization (WHO) highlight that vaccination programs are essential for reducing measles mortality by shifting the burden of disease away from infancy, the age group with the highest case fatality rate.
February 19 marks Oregon’s School Exclusion Day, a critical deadline when students who have not received required vaccines or obtained an exemption will be barred from attending school until the issue is resolved.
Public health officials are urging enhanced efforts to boost routine vaccination coverage and identify communities at risk for measles transmission to prevent widespread outbreaks.

Oregon’s Measles Crisis: The Growing Threat of Vaccine Exemptions and the Urgency of Immunization
PORTLAND, Ore. — Oregon is facing its largest measles outbreak in decades, driven by a record-high number of parents opting out of vaccinating their children. With a vaccine exemption rate of 9% among kindergartners, the state is at a crossroads in its fight against preventable diseases. In this interview, Senior Editor of World Today news, Sarah Mitchell, sits down with Dr. Emily Carter, a leading infectious disease specialist, to discuss the crisis, the role of vaccination in public health, and the steps needed to prevent future outbreaks.
the Alarming Rise in Vaccine Exemptions
Sarah Mitchell: Dr. Carter, Oregon’s vaccine exemption rate has reached a historic high of 9% among kindergartners. What does this mean for the state’s public health?
Dr. Emily Carter: This is a deeply concerning trend. When vaccination rates drop below the threshold needed for herd immunity—typically around 95% for measles—outbreaks become far more likely. The 9% exemption rate in Oregon is not just a number; it’s a warning sign. It indicates that significant portions of our population are vulnerable to highly contagious diseases like measles. This puts not only unvaccinated individuals at risk but also those who cannot be vaccinated due to medical reasons, such as infants or immunocompromised individuals.
Measles Cases and the Role of Vaccination
Sarah Mitchell: The CDC has reported 338 measles cases in the U.S. as 2020, with 29% occurring in the first quarter of 2024. Nearly all cases involve unvaccinated individuals. Why is vaccination so critical in preventing measles?
Dr. Emily Carter: Measles is one of the most contagious diseases known to humankind. A single case can lead to an outbreak if the surrounding population isn’t adequately vaccinated.The measles vaccine is incredibly effective—about 97% effective after two doses. Vaccination not only protects individuals but also creates community immunity,making it harder for the virus to spread. The data is clear: nearly all recent cases involve unvaccinated individuals or those with unknown vaccination status. This underscores the life-saving importance of vaccination.
School Exclusion Day and Its Impact
Sarah Mitchell: February 19 marks Oregon’s School Exclusion Day. Can you explain the significance of this deadline and its role in protecting public health?
Dr. Emily Carter: School Exclusion Day is a critical tool for ensuring that students are up-to-date on their vaccinations. It’s not just about compliance; it’s about safeguarding the health of the entire school community. Schools are high-risk environments for the spread of infectious diseases due to close contact among children.By enforcing this deadline, we ensure that unvaccinated students don’t pose a risk to others. It’s a reminder that vaccination is not just a personal choice but a community duty.
The Global Perspective: WHO and CDC Recommendations
Sarah Mitchell: Both the CDC and the World Health Organization (WHO) emphasize the importance of vaccination in reducing measles mortality. How does vaccination shift the burden of disease away from high-risk groups like infants?
Dr. Emily Carter: Infants are especially vulnerable to measles as they cannot receive the vaccine until they are at least 12 months old. Vaccination programs aim to create a protective barrier around these high-risk groups by ensuring that the broader population is immunized. When vaccination rates are high, the virus has fewer opportunities to spread, reducing the likelihood of outbreaks. This strategy has been instrumental in reducing measles-related deaths globally. The WHO and CDC’s recommendations are grounded in decades of scientific evidence showing that vaccines save lives.
Public health Strategies to Combat the Crisis
Sarah Mitchell: Public health officials are calling for enhanced efforts to boost vaccination coverage and identify at-risk communities. What steps should Oregon take to address this crisis?
Dr.Emily Carter: First, we need to address vaccine hesitancy thru education and community outreach. Misinformation about vaccines is a major driver of low vaccination rates, so clear, fact-based interaction is essential. Second, we must make vaccines more accessible by reducing barriers to access, such as cost or transportation. we need to strengthen partnerships between public health agencies, schools, and healthcare providers to identify and address pockets of low vaccination coverage. This is a collective effort that requires collaboration at all levels.
Looking ahead: Preventing Future Outbreaks
Sarah Mitchell: As oregon confronts this public health challenge, what is the key takeaway for parents and policymakers?
Dr. Emily Carter: The takeaway is clear: vaccination is our most effective tool against preventable diseases like measles. Parents should ensure their children are up-to-date on their vaccines, not just for their own protection but for the protection of their communities. Policymakers must support public health initiatives that promote vaccination and address the root causes of vaccine hesitancy. This crisis is a reminder that public health is a shared responsibility, and we all have a role to play in preventing outbreaks.
Conclusion
oregon’s measles outbreak underscores the critical importance of vaccination in protecting public health. With vaccine exemption rates at a record high and measles cases on the rise, immediate action is needed to boost immunization coverage and prevent further outbreaks. As Dr. Emily Carter emphasized, vaccination is not just a personal choice—it’s a community responsibility that saves lives.
