In the wake of a recent federal report revealing a decline in routine childhood vaccination rates for the 2022-23 school year, public health experts expressed dismay at the overall drop. However, one state stood out for lagging behind the rest of the nation: Idaho. The state exhibited the lowest percentage of kindergartners meeting school vaccination requirements for all major vaccines—measles, mumps, and rubella (MMR); diphtheria, tetanus, and acellular pertussis (DTaP); poliovirus (polio); and varicella (chickenpox)—with rates hovering around 81%, notably lower than the nationwide average of 93%.
Adding to the concern, Idaho also reported the highest percentage of exemptions from one or more required vaccines, reaching 12.1%, while the U.S. average was approximately 3%. Dr. Bethaney Fehrenkamp, a clinical assistant immunologist at Idaho WWAMI, a collaborative initiative involving the University of Washington School of Medicine and several states including Idaho, emphasized the broader implications, stating, "This is concerning not only at a state level but nationally because we're not the only state experiencing this; we just appear to be experiencing it a little more than other states."
Public health experts underscored the potential risks associated with clusters of unvaccinated or under-vaccinated children, citing the possibility of outbreaks of preventable diseases like measles. Measles is highly contagious and can lead to severe complications such as pneumonia, encephalitis (brain inflammation), and even death, according to the Centers for Disease Control and Prevention (CDC). Illustrating the gravity of the situation, a recent measles outbreak in central Ohio affected 85 children, with 80 of them being unvaccinated between November 2022 and February 2023. Similarly, Idaho experienced a measles outbreak last month that infected 10 people, marking a notable increase from the typical low incidence, with only two reported cases in the state over the past 20 years.
Dr. Kevin Cleveland, an associate professor at the College of Pharmacy at Idaho State University, emphasized the heightened risk of disease spread in under-vaccinated populations, stating, "When you have an under-vaccinated population and a contagious disease, it'll spread and it'll spread more easily."
Examining the situation further, concerns arise not only from the low vaccination rates but also from the type of exemptions allowed. While all states and Washington, D.C. permit exemptions for medical reasons, 45 states and D.C. grant exemptions on religious grounds, according to the National Conference of State Legislatures (NCSL). The combination of these factors underscores the need for a comprehensive approach to address the challenges Idaho faces in maintaining adequate childhood vaccination rates and preventing the resurgence of preventable diseases.
Amidst concerns over declining childhood vaccination rates revealed in a recent federal report, Idaho emerges as a focal point, grappling with a unique set of challenges. The state not only exhibits the lowest percentages of kindergartners meeting vaccination requirements but also reports the highest percentage of exemptions from required vaccines, reaching 12.1%.
A distinctive aspect of Idaho's vaccine landscape is the allowance of philosophical exemptions in 15 states, where parents can seek exemptions for their children based on "personal, moral, or other beliefs," according to the National Conference of State Legislatures (NCSL). This broad criteria for exemptions raises questions about the potential impact on overall vaccination rates.
Experts point to several factors contributing to the low rates, with access being a significant concern. Idaho's predominantly rural landscape, encompassing 35 out of 44 counties, coupled with a ratio of 174 physicians per 100,000 people, presents challenges in reaching healthcare providers and scheduling appointments.
The aftermath of the COVID-19 pandemic also looms large, potentially influencing vaccine hesitancy. The slow but steady rise in vaccine hesitancy, exacerbated by COVID-19, has led to concerns spilling over from the pandemic into other vaccines. Dr. Bethaney Fehrenkamp of Idaho WWAMI notes that decreased vaccination rates during the pandemic may stem from issues of access, availability, and fear of healthcare facilities, but misinformation and a lack of trust have further complicated the landscape.
Vaccine fatigue is another consideration, with individuals possibly feeling overwhelmed by recommendations for COVID-19 boosters and updated vaccines to combat emerging variants. Dr. Kevin Cleveland highlights this fatigue, noting, "Every time we talk about a vaccine, it goes back to the COVID vaccine. I think people are just a little tired. It's like, 'Oh, no, another vaccine.'"
Moreover, a potential cultural shift may contribute to the decline, as the severity of vaccine-preventable diseases has faded from public memory. Dr. Fehrenkamp emphasizes the contagious and serious nature of these diseases, expressing concern that society may have forgotten their gravity due to successful vaccination efforts.
Reflecting on historical data, the impact of vaccines becomes evident. Before the MMR vaccine's availability, measles alone led to 48,000 hospitalizations and 400 to 500 deaths annually in the U.S. Dr. Fehrenkamp underscores the importance of vaccination for societal protection, stating, "We've previously eradicated these diseases in the U.S., which is why I think maybe, culturally we have forgotten how serious and how detrimental they can be."
In navigating this complex tapestry of challenges, addressing access issues, countering misinformation, and fostering awareness about the gravity of vaccine-preventable diseases emerge as crucial steps in revitalizing childhood vaccination rates and safeguarding public health in Idaho.
Recognizing the challenges posed by declining childhood vaccination rates in Idaho, healthcare experts are advocating for proactive measures to address concerns and increase awareness. Dr. Bethaney Fehrenkamp emphasizes the importance of open and honest conversations between healthcare providers and parents to understand and alleviate vaccine hesitancy. She underscores the need for parents to feel well-informed and assured about their decision to vaccinate their children, emphasizing a commitment to enhancing public understanding of vaccine safety.
At Idaho WWAMI, efforts are underway to bridge gaps in healthcare access. Dr. Fehrenkamp highlights initiatives where students from Idaho with connections to underserved communities are involved in education. The goal is to equip these students with the knowledge and skills to return to their communities and contribute to filling healthcare gaps.
Dr. Kevin Cleveland, specializing in immunization outreach to underserved populations in Idaho, stresses the importance of bringing vaccines directly to rural or underserved communities. By making vaccines more accessible, particularly in workplaces or schools, there is a notable increase in vaccine uptake. This approach aligns with the principle of taking healthcare services to the people, addressing logistical challenges and ensuring that individuals can easily adhere to vaccination schedules.
