As rates of preventable diseases increase, improving vaccination rates is more important than ever. Oregon’s public health system is working on it. 5/14/2025

Rates of vaccine-preventable disease have risen in recent years.

Oregon saw 1,175 cases of pertussis (also known as whooping cough) reported in 2024. This was the highest number of cases reported in a single year since 1950, when 1,420 cases were reported.

Pertussis can make people very sick, and in some cases, lead to hospitalization or death. Children and infants are most at risk of serious illness or death.

Pertussis is a vaccine-preventable disease – meaning just that: it can be prevented. Getting vaccinated is the best way to avoid contracting the disease. Although it is possible for vaccinated people to get pertussis, the vaccine’s protection goes far beyond the first line of defense. Research has shown that being vaccinated against pertussis can reduce the risk of severe disease by as much as 60%.

Vaccination against pertussis is included in the 4:3:1:3:3:1:4 series. Also called the two-year-old vaccination series, these vaccines are recommended for all children by the time they turn two.

Two-year-old vaccination rates were rising in Oregon for nearly a decade before COVID-19 hit and rates began to fall. The reasons for this decline are not entirely clear, but contributing factors may include COVID-19’s strain on the health care system, vaccine hesitancy and misinformation. Increased social distancing and masking during this time also lowered the risk of exposure to pertussis and other communicable diseases, leading people to view the vaccine as less important.

Systemic barriers to access contribute to lower immunization rates among Oregon’s communities of color.

Even before vaccination rates began falling in recent years, Oregon has experienced significant immunization rate disparities. Communities of color are less likely to be vaccinated and more likely to get sick with vaccine-preventable diseases compared to white communities. White residents are vaccinated at a higher rate than the state’s average, and residents who are Black or African American, American Indian or Alaska Native, and Hawaiian or Pacific Islander are vaccinated at lower rates than the state’s average. OHA strives to close these gaps as part of its goal to eliminate health inequities in Oregon by 2030.

Collaborative efforts to prevent and respond to outbreaks occur locally and statewide.

OHA, local public health authorities (LPHAs), community partners and health providers are working together to make higher vaccination rates a reality by providing culturally relevant outreach and education and making vaccines easier to access.

Easier access can happen through things like:

Using mobile vaccine clinics to bring vaccines to people who are homebound, residents of long-term care facilities and people who live in rural areas
Setting up mobile vaccine clinics where people need to go anyway – like grocery stores, schools, places of worship, parks, community centers and office buildings
Offering vaccines at community events like festivals, music performances and street fairs
Offering translated materials and interpretation services at vaccine events
Partnering with community organizations to share culturally and linguistically relevant information with the communities they serve
Partnering with faith-based organizations and faith leaders to share vaccination information and host vaccine events

These are some examples of this work around Oregon:

In Crook County, the LPHA partners with schools and HeadStart programs to reach students and parents by offering immunizations at school parent nights.
In Clackamas County, the LPHA partners with culturally specific organizations to get the word out about immunizations. Recently, the Ukrainian Foundation created a video featuring Clackamas County Public Health’s Eastern European Liaison speaking in Ukrainian about childhood immunizations.
The Multnomah County Immunization Team partners with the Community for Positive Aging to host vaccine clinics and share information. In October, the Immunization Team presented and answered community members’ questions about the new COVID-19 vaccine formulation.

Programs like Vaccines for Children promote health equity by removing cost as a barrier to vaccination.

The Vaccines for Children (VFC) program provides free vaccines to kids whose parents may not be able to pay for them. It operates all around the country and provides vaccines to over 50% of Oregon’s children. VFC was created in response to the 1989-1993 measles epidemic in the United States, in which over half of the children infected were found not to have been vaccinated against measles.

Congress passed the Omnibus Budget Reconciliation Act of 1993, and the VFC program was born. The VFC program provides the vaccines to a nationwide network of public and private providers who administer the program locally. In Oregon, the CDC-sponsored Immunization Quality Improvement for Providers (IQIP) program supports VFC-enrolled partners by helping providers assess current practices, review immunization rates and set evidence-based, achievable goals for improvement.

The success of the IQIP program – which includes federal, state, county, provider and community partners – highlights the power of collaboration across the public health system.

In Deschutes County, Deschutes County Public Health (DCPH) staff used the IQIP program in gathering local clinics to form a community of practice. The group met quarterly, with each clinic developing immunization rate goals and implementing diverse interventions focused on using clinical data to reduce missed opportunities to vaccinate, catching up children who were behind on vaccinations, and streamlining processes to improve rates. From 2016 to 2020, participating practices raised immunization rates by more than 8 percentage points. Although most IQIP programs – including in Deschutes County – were paused when COVID-19 started, the program is regaining momentum and efforts are resuming around the state.

Building resilience: How Oregon tackles extreme weather's health risks 10/18/2024

Extreme weather in Oregon: A call for climate resilience

Oregon's climate isn't what it used to be. Summers are hotter, wildfires are more intense, and droughts seem to stretch on forever. These extreme weather events are our new normal, and for most of us the most striking impacts of climate change. They bring a wave of challenges that affect the health of our families and communities and deepen existing health inequities. This means the people most impacted by racism, poverty, and prejudice are also hit the hardest by extreme weather.

Our 2023 annual Climate and Health in Oregon Report shows how these climate threats facing our state affect the health of people who live here.

Read the full report: 2023 Climate and Health in Oregon Report.

Human impacts and human-centered solutions

These climate threats aren't just about rising temperatures—they're about real people facing real health risks:

Heatwaves endangering the lives of community members, especially older adults living alone and with low incomes.
Wildfire smoke polluting our air, leading to a spike in asthma and heart problems.
Droughts threatening our water supply, making clean drinking water harder to come by.

If you've been through a wildfire or had another extreme weather event hit close to home, this can be hard to read. It's personal. Sometimes, knowing what's coming helps, as well as having a role in the solution. This blog will both describe the health harms of extreme weather in Oregon and talk about what we can do to support a healthy future.

The good news is that we can work together to support community health in the face of these challenges.

Coming together to build resilience to extreme weather events

To tackle these challenges, we've teamed up with partners across the state—from community-based organizations to local health authorities. Together, we're building a resilient public health system that's ready for whatever mother nature throws our way.

Our long list of partners includes:

Local public health authorities (LPHAs)
Community based organizations (CBOs)
Regional coalitions
Health care and behavioral health providers
Public safety agencies
Faith-based institutions
Schools
Environmental agencies
The business sector

Together, we're building climate resilience by:

Responding to and preparing for health impacts: More frequent wildfires, heat waves and other extreme weather events are challenging our health systems like never before.
Planning for chronic health stressors: Poorer air or water quality have cascading impacts on mental health, food, access to healthcare, housing, income, transportation and other aspects of well-being.
Leading with equity: We are working to address the health, social and economic systems that contribute to making certain communities more vulnerable to climate-associated health risks.

Read on to learn how climate is challenging our communities, and what we can do about it.

Extreme heat: The health impacts of rising temperatures

If you've noticed that summers feel hotter than they used to, you're not alone. The year 2023 was the hottest on record globally. In Oregon, extreme heat events—those days when temperatures soar above normal—are happening more often and with greater intensity.

Here's the reality:

June 2021: An extreme heat event hit the Pacific Northwest, leading to 102 deaths, mostly among isolated, low-income older adults.
Rising temperatures: This trend isn't going away. As temperatures rise, so does the risk of heat-related illnesses and deaths.

Air quality: The health impacts of wildfire smoke

Wildfires are becoming larger and more severe, creating smokier air that can impact Oregonians' lung health and heart health.

The facts:

Respiratory health: In 2023, respiratory illness rates in some Oregon communities were nearly double the state average due to poor air quality. The following communities faced the most extreme impacts:

American Indian/Alaska Native
Black/African American
Native Hawaiian/other Pacific Islander

Long-term impact: The particles in wildfire smoke can cause both immediate and long-term health issues, including asthma and heart attacks.

These numbers aren't just statistics – they represent real people struggling to breathe.

Factors affecting susceptibility to extreme heat and wildfire smoke.

Water security: When the wells run dry

Across Oregon, more frequent and severe droughts, floods and growth of toxin-producing algae in water are threatening our water security—the ability to access clean, safe and affordable water.

Key concerns:

Drought: In 2023, 52 percent of Oregon experienced severe drought, with 30 percent facing extreme conditions.
Waterborne diseases: Rising temperatures and water scarcity are creating perfect conditions for diseases like Lyme Disease and West Nile Virus to spread.

Mental health: The hidden toll

While physical health impacts are more visible, the mental health toll of climate change is just as real. This can look like anxiety about the future or the trauma of losing homes and livelihoods to wildfires.

What we're seeing:

Youth anxiety: The 2022 Climate Change and Youth Mental Health Report revealed that many young people in Oregon are struggling with feelings of hopelessness and despair about the future.
Community impact: Extreme weather events are leading to increased rates of anxiety, depression and post-traumatic stress disorder (PTSD).

Oregon youth reporting feelings of anxiety, frustration and hopelessness about the future is a sobering reminder that extreme weather affects us all, in ways both seen and unseen.

Building resilience: Our path forward

Over the past several years, we've developed a resilience framework that's all about relationships—between public health, housing, healthcare, forestry, land use and community partners. This isn't just about physical infrastructure; it's about people and the connections that make our communities stronger.

Oregon Public Health Modernization funding is the backbone of this effort, providing resources that organizations need to build these vital relationships, innovate and work together toward a common goal of climate resilience.

Here is how the work is playing out across our state.

Community-based organizations: The heart of resilience

Supported by health modernization funding, community-based organizations (CBOs) across Oregon are stepping up to meet climate challenges head-on.

Spotlight:

Disaster Resilience Learning Network (DRLN): This network brought together 25 organizations, including Familias en Acción and the Micronesian Islander Community, to support communities of color impacted by climate disasters.

Many CBOs have also partnered with LPHAs to respond to extreme weather events. In 2020 and 2021, Northwest Family Services and Clackamas County Public Health Division helped residents evacuate from wildfires. In 2022 and 2023, they expanded their efforts to distribute air-conditioning (AC) units to those in need—providing not just relief from the heat, but a lifeline. Learn more about the partnership in this video:

Local public health authorities: On the front lines

Local public health authorities (LPHAs) are crucial in this fight, working with partners to create action plans tailored to their communities.

Spotlights:

Heat mapping campaign: In 2023, Washington, Clackamas and Multnomah counties' LPHAs collaborated on the Portland Metro Region Heat Mapping Campaign, creating a tool to understand how heat impacts different communities.

Tribal communities: Protecting heritage and health

For Oregon's nine federally recognized tribes, modernization funding is helping to preserve both health and cultural heritage.

Initiatives:

Environmental health assessments: Conducted in partnership with the Northwest Portland Area Indian Health Board, these assessments are crucial for protecting tribal communities from the impacts of climate change.

Oregon Health Authority: Supporting resilient communities

At OHA, we are centering equity in our efforts to modernize statewide public health infrastructure. This includes investments in climate equity, healthy homes and schools, land use and health, healthy waters, and epidemiology (the study of how health outcomes affect populations and why).

A few of our initiatives:

Grant funding: Programs like the Healthy Homes Grant Program help low-income households and those impacted by environmental justice factors equip their homes to withstand environmental hazards like harmful air quality and extreme heat.
Air conditioner and air filter distribution: We also administer a program to distribute air conditioners and air filters to Oregonians in need, helping them protect themselves from extreme heat and wildfire smoke.

OHA leads the state with investments in climate resilience, funding and technical support to our public health partners, and data tracking systems related to climate and health. These supports are not always the most visible, but we believe they are vital. They lay the foundation for our partner organizations as they innovate and work together toward a common goal of climate resilience.

Partnering for a healthier future

Addressing the impacts of extreme weather on public health is a critical priority for Oregon's public health system. By working together—through proactive measures and strong community partnerships—we can protect the health and well-being of all Oregonians. Continued investment in public health modernization is essential to meet these challenges head-on and ensure a healthier future for our state.
