1. Introduction
In the midst and aftermath of the COVID-19 pandemic, the response of governments represented a critical effort toward mitigation and prevention. The urgent and extraordinary circumstances unquestionably strained existing public health systems beyond expected limits, exacting a necessity for efficient and effective policy outcomes. In the U.S., the immensity of this challenge intensified the inherent successes and shortcomings of federalism as public officials at all levels of government balanced policy options and directives with available resources and capabilities [
1,
2]. The division of powers provides a full spectrum of state responses in health emergency situations [
3,
4]. Notably, divergences in politics and administration among the states may have yielded dissimilarities in results [
5,
6], especially relating to the key policy pursuit of COVID-19 vaccinations [
7,
8,
9].
The purpose of this study is to examine the political and administrative influences contributing to differences in COVID-19 public health policy outcomes among the U.S. states. Specifically, in the framework of federalism, what is the impact of state political and administrative contexts on COVID-19 vaccination rates? Focusing on COVID-19 vaccinations as a measure of policy execution, this research incorporates four hypotheses to address the overall effect of politics-administration in the pandemic response of American states. Primarily, political contexts entail social and cultural governing dispositions that may motivate state persuasions toward both public health policy and administration [
10,
11,
12,
13,
14,
15,
16]. However, administrative contexts encompass the institutional arrangements and governance designs of implementing agencies, involving aspects of decentralization, independence, and administrative aptitude in state public health services [
17,
18,
19,
20,
21,
22,
23,
24]. Utilizing indicators for these state features of politics and administration, this study offers a uniquely comprehensive view of the potential impacts on public health policy during the height of the COVID-19 pandemic and vaccination campaign [
25]. The findings suggest that state political and fiscal orientations display significant associations with vaccination rates, while other administrative factors did not.
Prior research has explored issues of COVID-19 policy implementation [
26,
27,
28], including the political implications and policy outcomes of state selection in mask mandates and lockdowns [
29,
30,
31,
32]. However, volatile attributes of American federalism exhibited during the pandemic encourage further consideration in this area [
33,
34], particularly toward the core policy goal of vaccination. Well recorded is the expanded federal role in public health due to COVID-19 [
35,
36,
37] and in the pivotal development and free distribution of vaccines [
38]. Yet, states were responsible for the coordination of vaccines, the determination of critical populations, and the support and monitoring of vaccine allocation in communities [
39]. This study observes that imperative facet, adding to this gap of understanding with a dual vantage point that comprises both political and administrative effects in COVID-19 public health policy in U.S. states during this emergency event.
From a theoretical perspective, policy outcomes epitomize the broader conceptual linkage of the politics and administration relationship. Foundational works in the field suggest that the separational ‘dichotomy’ generally serves as an abstract distinction of influence among executive and legislative roles [
40,
41]. Within this normative premise, the bridging element of policy represents an area of complementarity between politicians and administrators in the intersect of application toward addressing public interests [
42,
43], particularly magnified by the overlapping operations and demands of contemporary federalism and governance [
44,
45]. In other words, aside from the larger philosophical debate, public policy best signifies the authentic synchronization of political and administrative enterprise in governmental functionality toward implementation [
46]. This study aims to add to the continued evolution of the politics-administration nexus within the overarching theme of federalism and the related repercussions revealed through variant public health policy results in extreme situations of service complexity and civic need.
The organization of this study is as follows. First, a review of the literature describes federalism and politics-administration for public health policy in the U.S. states, which informs the theoretical expectations. Next, a description of methods identifies the research approach, followed by data analysis and interpretation of the findings. Finally, a concluding discussion addresses implications and recommendations for future research.
2. Federalism and Politics-Administration in Public Health Policy
The American federal system demarcates powers held by the national and fifty state governments, which crafts a multipart arrangement of intergovernmental relationships and balancing tensions in governance [
47,
48]. Within this assembly, interactions and internal policies exemplify vast mixtures in political formulation spurred by geographical, ideological, and cultural peculiarities [
49]. Federalism impacts government management and, in turn, policy outputs by dictating the manner of networks and interfaces among entities, demonstrated in patterns of traditional top-down policy diffusion and more novel groupings of localized and interdependent configurations [
50]. Such conditions stimulate policy learning and innovation, as the states regularly assume the role of ‘laboratories’ in experimenting with policy alternatives [
51,
52]. Yet, the division of powers and patently exclusive political contexts of the states create a fracturing of public policy, which is most apparent in specialized areas, such as healthcare, and in times of crises [
53].
In public health, the federal structure acts as a mode of devolution in which the administration of massive national health platforms, such as Medicaid and the Patient Protection and Affordable Care Act (ACA), rests with the states, creating an assortment of programmatic identities typically reliant upon state resources and political inclinations [
54]. Such fragmentation inevitably warrants inconsistency that, while beneficial for policy invention, may limit the propensity for uniform remedies to widespread problems [
55]. Amid the challenges of the COVID-19 pandemic, existing imbalances in healthcare governance coupled with leadership gaps and partisan disputes generated a polarized and dualistic approach, establishing concurrently divergent, and in some cases contradictory, public health policy responses [
2,
5,
7,
16]. Noticeably, the ever-expanding disconnect between the federal and state governments in this policy arena was deepened, leaving states and localities in control by default [
1,
35].
A federal system fosters allotments of authority and action among governments, with coordinating relationships between elected officials, implementing agencies, and constituents [
56,
57]. The nature, composition, and application of government all impact institutional character and layout, which lend to special aspects of autonomy, originality, and dissemination [
58,
59], principally in areas such as public policy [
60,
61] and revealed both during and after the COVID-19 pandemic [
17,
62,
63]. Each state cultivates discrete relationships in the devise and delivery of public health policy, resulting in interspersed responsibilities and obligations [
64] that may prompt deviating outputs. Of particular interest, during the COVID-19 pandemic, wide variation existed among states in the percentage of fully vaccinated persons, with the highest rate in Rhode Island (80.5 percent) and the lowest in Alabama (50.2 percent) [
38]. Thus, within a broader setting of federalism, this study distinctively seeks to advance understanding of the political-administrative dynamic within U.S. states that produced such disparate policy outcomes.
2.1. Theoretical Expectations
2.1.1. State Political Contexts in Public Health
Political factors guide an array of government properties evident at the state and local levels, including structures, policy, and efficacy [
65,
66,
67,
68]. In the COVID-19 pandemic, state political orientations, expressive of partisan divides and state-local disagreement, assumed a stake in policy decisions and reactions. For instance, the political stance of governors may have been persuasive in state policies toward mask mandates [
29], and such policies met public resistance in conservative-leaning states [
31]. As a result, policy responses fluctuated, and the actions taken within individual states and among local governments exposed preexistent tensions and politically motivated catalysts, contributing to differences in outcomes such as mortality rates [
69]. Backlashes against executive orders and bureaucratic policymaking fueled dissensions between state legislatures and governors as well as intrastate political polarizations and compliance pushback from local governments [
13,
27]. Such divisions among the states, overlaying elements of partisan discrepancy, conflicts and distrust, and newly strained intergovernmental relationships, convey a potency of political factors in public health policy during the COVID-19 emergency.
The influence of state agencies in policy decisions and formation appears more expansive within the executive branch, classically with governors, as opposed to the more fractured political interests embodied within state legislatures and local governments [
11,
70]. In this way, the impetus for policy aligns with the public choice theory of political economy, alleging that public officials will habitually act in self-interest by endorsing policies that are most amenable to their own organizations, political expediencies, and constituents [
14], which shapes the temperament of the policymaking process and the character of the policy approach [
15]. Of interest, Democrat governors depict a higher amenability to state health policy adoption and implementation [
71,
72], possibly associated with higher levels of COVID-19 vaccination rates [
69]. Based on the above, Hypothesis 1 posits:
Hypothesis 1.
A state with a Democrat governor is positively associated with COVID-19 vaccination rates.
In situations of divided government, where competing political parties split control of the governorship and state legislature, the prospect for policy compromise may be more limited and may prolong the timeframe for action [
73,
74]. In public health policy, this effect is often accentuated, predictably at the state level where executive responsibility in healthcare is commonly more concentrated and centralized [
54]. During the pandemic, policies for infection mitigation, such as wearing a mask, necessitated concerted efforts from both state executive and legislative actors [
26,
30], which potentially amplified political leanings in COVID-19 vaccination policies [
8]. As such, Hypothesis 2 posits:
Hypothesis 2. A state with divided government is negatively associated with COVID-19 vaccination rates.
2.1.2. State Administrative Contexts in Public Health
In the U.S., state public health governance structures refer to the organizational relationships among state and local units in the delivery of public health services [
64,
75]. For state policies, the institutional interactions between state officials/agencies and local governments may yield improved cooperation and coordination in implementation and sponsorship [
18,
61]. However, internal state structures vary in degrees of centralization, which prescribes interorganizational affiliations among state agencies and local entities [
4,
75]. For example, the institutional location within state government may portend more control over policy implementation by those public health agencies afforded greater independence in operation [
22,
70]. Recent research suggests that decentralized structures may increase cooperative ventures among officials, aiding collaborative policymaking and joint outcomes in public health (3,76] and interlocal sustainability [
77].
Assessing the impact of COVID-19, propositions for improved public health systems include decentralized tactics, such as community-based health initiatives for enhanced partnership and communication among organizations [
28,
62]. Decentralized public health configurations proved to be effective during the pandemic, as states and localities filled in the gaps of implementation from federal directives [
26]. In contrast, internationally, strongly centralized approaches were less effective in public health objectives and impeded the ability of local entities to handle rapidly evolving conditions [
78,
79]. However, some U.S. states with higher levels of local government autonomy witnessed fewer independent actions taken by local officials in addressing COVID-19 issues [
9], while such states were also more likely to experience preemption and increased centralization of policy directives by state governors during the pandemic [
32]. Based on the above arguments, Hypothesis 3 posits:
Hypothesis 3.
A state with decentralized public health governance structures is positively associated with COVID-19 vaccination rates.
Existing research of local immunization rates and programs among U.S. health departments distinguishes several factors that may enrich the efficacy of service and policy delivery, including organizational leadership and alignment, resources, political relationships, community partnerships, credibility, and cultural competency [
23]. The capacity attributes of states, including rural orientations that may be symptomatic of lower socioeconomic status and healthcare employment per capita, signal associations with state systems for medical countermeasures and distribution during public health emergencies [
21,
80]. This lends to the aspect of state administrative capacity, comprising components of public health workforce and financial disposition, which may anticipate the ability of states to administer effectual services and outcomes for all populations [
81,
82,
83], particularly in severe public health conditions [
17]. Thus, accounting for the inherent capacity contrasts of the U.S. states, Hypothesis 4 posits:
Hypothesis 4.
A state with greater administrative capacity is positively associated with COVID-19 vaccination rates.
5. Discussion and Implications
The purpose of this study was to examine the political and administrative influences contributing to differences in COVID-19 public health policy outcomes among the U.S. states. Specifically, in the framework of federalism, what is the impact of state political and administrative contexts on COVID-19 vaccination rates? The findings display traits related to state political orientations, namely the party affiliation of governors, along with fiscal attributes of state GDP exhibited significant associations with COVID-19 vaccination rates, while other indicators of administrative design and capacity did not. The results provoke a broader discussion of the proper roles ascribed to politics and administration in effectual policy execution and the consequent positions of governments within federal systems for future public health emergencies.
In countering COVID-19, the national government activated emergency public health procedures. However, delays in action and coordination among officials and agencies affected applications [
63]. Here, the scheme of federalism fittingly delegated remaining assignments to the states, which resulted in a deviation of policy approaches reflective of the political temperaments in individual states [
10,
27,
37,
54]. Ultimately, based on the findings of this research, the politics-administration nexus signaled an overarching predominance of political persuasion in the vaccination policy outcomes of states, which seemingly rendered existing administrative structures and conventions as immaterial. These interpretations are consistent with assertions from extant studies that suggest politics held a disproportionate locus of influence in the reaction and subsequent activities of governments toward the mitigation of COVID-19 through public policy, not just in the United States but worldwide [
34,
76,
90]. Moving forward, this supposition is both revealing and disconcerting for public health, as even the most diligent and proactive protocols set forth by administrative agencies in preparation for extraordinary health events may be displaced by prevailing political sentiments of the moment.
What is more, the findings raise additional questions for the politics-administration relationship in public health crises and the necessity of aligning tasks within federalism for the coordination of equitable policy outcomes. Debatably, politics symbolize the formal arbiter for administration in a representative democracy, subject to the voting preferences of the citizenry and bound by the authorizations and oversight of elected officials in policy implementation [
40]. Conversely, the assumption of expertise places administrators in a presumably better position to address specific policy contingencies, such as public health, creating opportunities for politics-administration synchronization in outputs that will be most beneficial to the overall public interest [
4,
42,
51,
56]. Modern iterations of the politics-administration dichotomy suggest a continuum model that coalesces roles of political and administrative actors for enhanced collaborative interactions and leadership [
44]. Yet, the politicization of major policy functions, such as healthcare, may limit the aptitude afforded to administrators to operate accordingly [
1,
45,
46]. As current research shows, social behaviors and attitudes typify fragmented political dispositions toward the issues of COVID-19 and vaccines among state populations and communities, demonstrating an impact on the administrative campaigns and policy efforts toward vaccination [
16,
81,
91,
92]. Relatedly, the findings of this study portend serious considerations for the cooperative link of politics-administration in producing universal policy outcomes at the state level when facing massive public health predicaments on a scale of federalism.
As an example, the results of this research indicate that fiscal capacity, represented by state GDP, may have been instrumental in vaccination rates, which suggests that economic disparities among the states may have obstructed the ability to attain equivalent outcomes. State GDP is a function of economic policy that prefigures the political orientation and administrative organization of state systems. The national government sustained the financial volume to spearhead vaccine development and distribution, while state governments typically did not maintain adequate assets for such endeavors [
39]. Historically, state governments have required a balancing of revenues and expenditures and have been prohibited from raising deficits [
93], which could negatively constrict a state’s flexibility in response to a COVID-type incident. As witnessed in the pandemic, such instances of federalism require a reciprocation of corresponding resources to obtain comparable results, which the states did not possess. During the COVID-19 emergency, the national government dramatically increased health spending from
$13 billion in 2019 to
$135 billion in 2020, while state and local governments augmented their health expenditures by only 9 percent from
$93 billion to
$102 billion [
94]. Especially, the former spent over
$30 billion on vaccine development and distribution [
38]. To ameliorate such policy discrepancies as beheld among the states for vaccinations, the findings of this study propose evidence for an expanded role of national governments in confronting COVID-level public health situations with a compatibly more localized duty for state-level governments and entities. As such, administrative and political officials in federal systems may seek more coordinated and anticipatory policy frameworks that designate appropriate best practices for each, with the objective to mitigate impediments prior to emergency events. This may likewise address operations most suitable to centralized and decentralized structures that are conducive to consistent and equitable policy effects, while in consideration of preexisting economic and capacity disparities among levels of government that may catalyze escalated political polarization and influence within federal configurations.
Certainly, there is need for further research. Enhanced understanding is required to distinguish those factors that produced such incongruent COVID-19 vaccination policy results in the U.S. states and globally. This is particularly accentuated by the observed disparities in public health equity, including the COVID-19 vaccination and mortality rates of minority populations [
84,
92,
95]. Outside of this study, several restrictive factors may have affected the policy responses of governments during the pandemic, involving institutional limitations and internal dynamics, the scope of policy persuasion, and the range of interventions available to state and local policymakers [
47,
57]. These constructs relate to Peterson’s [
96] focus on the categories of public policy, such as developmental versus redistributive policies for the proper division of work among the federal, state, and local governments. Future research may want to review alternating responsibilities in federal systems for prior public health issues and examine viable functions assigned to each level of government. Of note is further investigation into the appropriate roles for politics and administration in public health policy, identifying areas of overlap and the potential for strengthened complementarity in collaborative governance, and explicitly how such dynamics may be harnessed to promote innovations of improved protocols and uniformity in outcomes for population health and large-scale vaccination campaigns.
