What Accounts for Differing Vaccination Rates?

Jan Plotczyk • August 3, 2021
 
We would not expect every Eastern Shore county to have identical covid-19 vaccination rates, and they don’t — but what accounts for the differences that range from 43% to 65% vaccinated? We’ll look to politics, social vulnerability, and race/ethnicity for answers.

Vaccination Rate Differences and Politics

It’s been pretty well documented that there’s a correlation between covid-19 vaccination levels and 2020 presidential election voting patterns. Numbers show that, overall, states and counties that voted for Biden have higher vaccination rates than states and counties that voted for Trump.

Numerous polls (KFF, Monmouth, Washington Post-ABC News, and others) have consistently found that Republicans are much more likely to say that they definitely do not want to get vaccinated and Democrats are much more likely to report having been vaccinated.

Data show that the top 22 states (including D.C.) with the highest adult vaccination rates all went for Joe Biden in the 2020 presidential election. Maryland is number six on that list, as of July 28. Trump won 17 of the 18 states with the lowest adult vaccination rates. Almost all U.S. counties below 20 percent vaccination rates lean Republican, and almost all above 65 percent lean Democratic.

Do the nine counties of the Eastern Shore follow this pattern? Let’s look at the data for percent of total population that has gotten at least one shot, as of July 27. Because these are rates of total population, they are much lower than rates calculated with only adults.


The two counties that went for Biden — Talbot and Kent — have the highest (65.9%) and third highest (61.5%) vaccination rates in this group. Worcester County is the outlier — it went for Trump by 17 points, but has the second highest vaccination rate (63.1%). Wicomico County was close in the election; it went for Trump by only 1.9 points, but has the second lowest vaccination rate (47.3%) in this group.

 

For comparison, Maryland’s vaccination rate is 59.6%. In the U.S. it is 56.9%.

 

Overall, the pattern mostly holds true for the Eastern Shore counties, although it is not the case that vaccination rate is proportional to support of either candidate.

 

In the past few weeks, some GOP lawmakers and conservative media figures have changed course and are now encouraging hesitant people to get vaccinated. The current sudden rise of cases, hospitalizations, and deaths due to the extremely contagious and virulent delta variant is overwhelmingly in states and counties that have lower vaccination rates. CDC Director Rochelle Walensky called it a “pandemic of the unvaccinated.”

 

Vaccination Rates and Social Vulnerability Index

 

It is clear that vaccination rates for counties do not depend solely on partisanship. For an insight into what some of those other factors could be, let’s take a look at vaccination rates and the Social Vulnerability Index.

 

The Social Vulnerability Index was created by the Centers for Disease Control and Prevention more than 20 years ago to help emergency response planners and public health officials identify and map communities that will most likely need support before, during, and after a hazardous event. The coronavirus pandemic is one such hazardous event.

 

The index assesses four themes in each community — socioeconomic status, household composition and disability, minority status and language, and housing type and transportation. Scores are used to determine the degree to which these factors would influence the ability of local officials to react effectively to disasters and disease outbreaks.

 

Scores are generated at the overall county level and for each theme. They are ranked on a scale of 0 to 1, with 1 being the most vulnerable.

 

Social Vulnerability Index Themes Defined:


We would expect to see that counties with higher social vulnerability scores would have lower vaccination rates, due to difficulties in reaching populations of elderly residents, people with limited English proficiency, those without transportation, etc.

 


Queen Anne's County has a Social Vulnerability Index of 0.00 in the chart above — the lowest vulnerability score. We see that the four counties with the lowest social vulnerability scores — Talbot, Worcester, Kent, and Queen Anne’s — have the four highest vaccination rates in the group. The five counties with the highest vulnerability scores have the lowest vaccination rates in the group.

 

Vaccination Rate Disparity by Race/Ethnicity

 

Finally, what role does race/ethnicity play in vaccination rates? Unfortunately, there are no public data on vaccination status by race/ethnicity at the county level, so we’ll have to look at Maryland as a whole.

 

The Kaiser Family Foundation looked at vaccinations by race/ethnicity for the 40 states that reported those data. They found that across all these states, the percent of White people who have received at least one covid-19 vaccine dose (48%) was roughly 1.3 times higher than the rate for Black people (36%) and 1.2 times higher than the rate for Hispanic people (41%) as of July 19.

 

Maryland has done a bit better. Higher percentages of each group have been vaccinated compared with the 40-state composite, but disparities still exist. The percent of White people who have received at least one dose as of July 19 is 61%. This is 1.2 times higher than the rate for Black people (51%) and 1.1 times higher than the rate for Hispanic people (54%).

 


Black people account for 30% of Maryland’s population, but only 26% of total vaccinations; 37% of covid deaths were among Black people. Covid-19 cases were not reported by race/ethnicity in Maryland.

 

Hispanic people account for 11% of Maryland’s population, but only 10% of total vaccinations; 9% of covid deaths were among Hispanic people.

 

White people account for 55% of Maryland’s population and 56% of total vaccinations; 50% of covid deaths were among Whites.




The share of vaccinated Black and Hispanic people has been growing recently relative to White people.

 

Recent surveys reveal that the population of unvaccinated can actually be subset into two groups: those who are adamant in their refusal of the vaccine (the “definitely nots” — 45% of unvaccinated), and those who are open to being persuaded (the “wait and sees” — 35% of unvaccinated). The former group is overwhelmingly White, Republican, and younger, and represents 15% of Americans; the latter group includes many younger people, Black and Hispanic Americans, and Democrats.

 

Among the “definitely nots, ” 83% believe that the seriousness of covid-19 is exaggerated, and 88% are not worried about getting sick from covid. Among the “wait and sees,” 78% believe the vaccines are not as safe as they are said to be, 44% say they would be more likely to get vaccinated if the vaccines gained FDA approval (rather than provisional approval), and 46% state they would be more likely to get vaccinated if they could do it at their own doctor’s office.

 

There didn’t look like there was much hope of vaccinating our way out of this pandemic voluntarily. But people may be changing their minds — vaccinations have recently risen in areas hard hit by the delta variant. And lately, some private companies, some local and state governments, and the federal government have decided to require that employees either be vaccinated or wear masks and social distance and get tested weekly or more often. A few private companies are making vaccination a condition of employment. And some businesses (restaurants and theaters, for example) are requiring their patrons be vaccinated. This may be the way out of the mess we’re in.

Common Sense for the Eastern Shore

By John Christie December 16, 2025
When I practiced law, much of my litigation involved issues arising under federal antitrust laws. The Department of Justice (DOJ) was my frequent adversary in court. In some cases, DOJ challenged a client’s conduct as anticompetitive. In others, they claimed an intended client merger would create a monopoly. Some of these DOJ court battles were won, others were not. Overall, I had great respect for DOJ lawyers. They were professional, well prepared, and dedicated to their mission of seeing justice done. They were courteous, honest, and forthright with the courts before which we argued our cases. In those days, without resorting to social media or press conferences, the DOJ spoke entirely through its court filings. Although as an advocate I took issue with various DOJ investigatory decisions as well as decisions to initiate litigation, I never thought politics was involved. Post-Watergate internal rules strictly limited communication with any figures at the White House. Not so, it seems, anymore. Beginning last January 20, all of this changed rapidly and spectacularly . On March 14, Trump triumphantly arrived at the main DOJ building in D.C. to be welcomed by a group of carefully selected VIPs. He was greeted by Pam Bondi, his chosen new attorney general, who exclaimed, “We are so proud to work at the directive (sic) of Donald Trump.” Bondi’s boast that the DOJ now worked at the president’s behest was something never said before and, in effect, surrendered the department’s long and proud independence. And Bondi’s comment was not an empty gesture. As chronicled by reporters Carol Leonnig and Aaron Davis in their new book, Injustice: How Politics and Fear Vanquished America’s Justice Department , within hours of being sworn in, Trump and his lieutenants began punishing those at the Justice Department who had investigated him or those he considered his political enemies. Career attorneys with years of experience under many administrations were fired or reassigned to lesser work, or they resigned. As Leonnig and Davis report, what followed was “the wholesale overthrow of the Justice Department as Trump insert[ed] his dutiful former defense attorneys and 2020 election deniers atop the department.” [Source: Injustice , p. xix.] In the place of years of experience, the new team appears credentialed simply by loyalty to the president’s causes. The DOJ’s conduct in court has since caused damage to judicial and public faith in the integrity and competence of the department. Just Security is an independent, non-partisan, daily digital law and policy journal housed in the Reiss Center on Law and Security at the New York University School of Law. Since January 20, it has documented federal judicial concerns about DOJ conduct. In 26 cases, judges raised questions about DOJ non-compliance with judicial orders and in more than 60 cases, judges expressed distrust of government-provided information and representations. This count was taken the day after a federal court dismissed the DOJ cases against former FBI Director James Comey and New York Attorney General Letitia James. [Source: Just Security , “The ‘Presumption of Regularity’ in Trump Administration Litigation,” Nov. 20, 2025.] As summarized by the Georgetown Law Center’s Steve Vladeck, “It’s one thing for the Department of Justice to so transparently pursue a politically motivated prosecution. But this one has been beset from the get-go with errors that remotely competent law students wouldn’t make. Indeed, it seems a virtual certainty that the Keystone Kops-like behavior of the relevant government lawyers can be traced directly to the political pressure to bring this case; there’s a reason why no prosecutors with more experience, competence, or integrity were willing to take it on.” [Source: One First , Nov. 24, 2025.] Rather than accept criticism and instead of trying to do better, Bondi’s DOJ and the Trump administration lash out in a fashion apparently aimed at demeaning the federal judiciary. At a recent Federalist Society’s National Lawyers Convention, Deputy Attorney General Todd Blanche, one of Trump’s former defense attorneys, attributed the Trump administration’s myriad losses in the lower federal courts to “rogue activist judges.” He added, “There’s a group of judges that are repeat players, and that’s obviously not by happenstance, that’s intentional, and it’s a war, man.” Deputy Chief of Staff Stephen Miller decries each adverse ruling against the Trump administration as just part of a broader “judicial insurrection.” Not to be left behind, Trump himself regularly complains of “radical left lunatic” judges. In addition to the harm these comments inflict on the federal courts, their premise is simply not true. According to a survey by Vladeck, as of Nov. 14, there were 204 cases in which federal district courts have ruled on requests for preliminary relief against the Trump administration. In 154 of them, district judges granted either a temporary restraining order, a preliminary injunction, or both. Those 154 rulings came from 121 district judges appointed by seven presidents (including President Trump) in 29 district courts. In the 154 cases with rulings adverse to the Trump administration, 41 were presided over by 30 Republican-appointed judges, fully half of whom were appointed by President Trump. No, it is no longer your grandfather’s Department of Justice. John Christie was for many years a senior partner in a large Washington, D.C. law firm. He specialized in anti-trust litigation and developed a keen interest in the U.S. Supreme Court about which he lectures and writes.

The Salisbury City Council has appointed longtime public servant Melissa D. Holland to fill the vacancy in District 2. Holland was selected on Dec. 1 after the council reviewed several applicants. A 27-year resident of Salisbury, Holland brings more than 20 years of experience in government, education, and administration. As executive assistant to the president of the University of Maryland Center for Environmental Science, she currently oversees operations, budgeting, communications, and planning. Before joining UMCES, Holland worked for nearly 11 years with the Wicomico County Council, gaining extensive experience in legislative procedure, constituent services, research, and budget preparation. Her background includes positions with the Wicomico County Board of Education, the State of Maryland’s Holly Center, and multiple early-learning programs. Approved by a 3-1 council vote, Holland was selected based on her administrative expertise and long-standing community involvement. (Salisbury’s City Council is now comprised of only women.) She has a bachelor’s degree in legal studies from Post University and an associate degree from Wor-Wic Community College. She has also served as PTA president at East Salisbury Elementary and Wicomico Middle School. In her application, Holland emphasized her commitment to maintaining transparency in city government and ensuring that District 2 residents remain informed and represented. “I plan to be well-informed on the issues that matter to the citizens of Salisbury and to listen to their concerns carefully,” she wrote. “I want to make a positive and lasting impact on our city.” Holland’s appointment restores the City Council to full membership as it faces debates over budgeting, infrastructure planning, and local governance initiatives. She is expected to begin constituent outreach immediately and participate fully in the selection of the next council president.

Voters in Hurlock have delivered sweeping changes in this year’s municipal election, as Republican and GOP-aligned candidates won key races there. The results mark a setback for Democrats and a significant political shift in a community that has historically leaned Democratic in state and federal contests. The outcome underscores how local organizing and turnout strategies can have an outsized impact in small-town elections. Analysts also suggest that long-term party engagement in municipal contests could shape voter alignment in future county and state races. Political analysts warn that ignoring municipal elections and ceding them to the GOP could hurt the Maryland Democratic Party in statewide politics. Turnout increased by approximately 17% compared with the 2021 municipal election, reflecting heightened local interest in the mayoral and council races. Incumbent Mayor Charles Cephas, a Democrat, was soundly defeated by At-Large Councilmember Earl Murphy, who won with roughly 230 votes to Cephas’s 144. In the At-Large Council race, Jeff Smith, an independent candidate backed by local Republicans, secured a 15-point win over Cheyenne Chase. In District 2, Councilmember Bonnie Franz, a Republican, was re-elected by 40 percentage points over challenger Zia Ashraf, who previously served on the Dorchester Democratic Central Committee. The only Democrat to retain a seat on the council was David Higgins, who was unopposed. The Maryland Republican Party invested resources and campaign attention in the Hurlock race, highlighting it on statewide social media and dispatching party officials, including Maryland GOP Chair Nicole Beus Harris, to campaign. Local Democrats emphasized support for Mayor Cephas through the Dorchester County Democratic Central Committee, but the Maryland Democratic Party did not appear to participate directly.

In what political observers are calling a clear break from Maryland’s moderate Republican establishment, Wicomico County Executive Julie Giordano chose former Gov. Bob Ehrlich — not former Gov. Larry Hogan — as the guest of honor at her re-election fundraiser in late October. Billed as Giordano’s annual Harvest Party, her event drew conservative activists from across the lower Eastern Shore and featured Ehrlich as keynote speaker. This was immediately read by insiders as a signal that Giordano will embrace the party’s right-wing base ahead of 2026, distancing herself from Hogan’s more centrist, bipartisan image. “Bringing in Bob Ehrlich instead of Larry Hogan wasn’t accidental,” one longtime Republican strategist said. “It shows Giordano wants to plant her flag with the MAGA-aligned wing of the party, the same voters who now dominate Maryland’s Republican primary base.” Hogan, who has hinted at another run for governor, was notably absent from this year’s Tawes Crab and Clam Bake in Somerset County, a high-profile gathering long considered essential for statewide contenders. Coupled with Giordano’s public alignment with Ehrlich, Hogan’s absence has fueled speculation that his influence within Maryland’s GOP is slipping. Those doubts were amplified by new polling data. A statewide survey commissioned by the Baltimore Banner found Gov. Wes Moore (D) leading Hogan 45% to 37% in a hypothetical 2026 matchup, with 14% undecided. The poll, conducted by phone and web from Oct. 7–10 among more than 900 registered voters, carries a margin of error of 3.2 percentage points. The results suggest that while Hogan remains popular among moderates and independents, Moore continues to hold a firm advantage statewide, particularly among Democrats and younger voters. Giordano’s decision to align herself with Ehrlich rather than Hogan further illustrates the ideological divide defining Maryland Republicans heading into 2026. As the party drifts further to the right, analysts say Hogan’s brand of pragmatic centrism may no longer have a natural home in today’s GOP. For now, Ehrlich’s appearance in Salisbury is being seen as a symbolic moment, one that cements Giordano’s status as a leading figure in the state’s Trump-aligned movement and underscores how quickly the political winds have shifted. For Hogan, once seen as the Republican best positioned to reclaim the governor’s office, that shift may mark the end of an era.

Can Maryland create a new congressional map that will flip the state’s sole Republican district to the Democrats? Gov. Wes Moore has created a Governor's Redistricting Advisory Commission to consider mid-cycle redistricting and Maryland has jumped into the redistricting fray. The commission will conduct public hearings, solicit public feedback, and present recommendations to the governor and Maryland General Assembly. “My commitment has been clear from day one — we will explore every avenue possible to make sure Maryland has fair and representative maps,” said Moore. “And we also need to make sure that, if the president of the United States is putting his finger on the scale to try to manipulate elections because he knows that his policies cannot win in a ballot box, then it behooves each and every one of us to be able to keep all options on the table to ensure that the voters’ voices can actually be heard .” Moore’s commission is one of those options — a response to Trump’s call to Republican-led states to create more GOP House districts before the 2026 midterm elections. Three GOP states — Texas, Missouri, and North Carolina — have completed a Trump gerrymander for a gain of seven seats and three more states — Indiana, Utah, and Ohio — could create new maps with a total of four additional Republican seats. That would make 11, should they withstand challenges. Democratic-led states made a lot of noise at first about countering these GOP efforts, but only California and Virginia have campaigns for new maps underway. California wants to flip five seats and Virginia hopes for up to four. Optimistically, that could add up to as many as nine. Maryland’s goal would be to add one Democratic seat. Other states on both sides could soon follow, in some cases taking advantage of existing redistricting deadlines or ongoing litigation. Maryland State Senate President Bill Ferguson (D-Balto City) is not in favor of mid-cycle redistricting, calling it too dicey. “Simply put, it is too risky and jeopardizes Maryland’s ability to fight against the radical Trump administration. At a time where every seat in Congress matters, the potential for ceding yet another one to Republicans here in Maryland is simply too great,” Ferguson wrote in a letter to Senate Democrats. Rep. Andrew P. Harris (R-MD01), whose district would be targeted by redistricting, called the effort "the most partisan thing you could do." He whined, “It just wouldn’t be fair.” Harris warned that any redistricting could backfire on the Democrats. “We will take this to court, it will go as high as necessary, and in the end, a judge could draw a map that actually has two or three Republican congressmen,” Harris said. “I’d caution the Democrats, be careful what you wish for.” Harris and his wife, Maryland GOP Chair Nicole Beus Harris, have perhaps already worked out a strategy. The Governor’s Redistricting Advisory Commission, last constituted by Gov. Martin O’Malley in 2011, will begin its work this month. The five-member commission includes: Chair: Senator Angela Alsobrooks Senate President Bill Ferguson or designee Speaker Adrienne A. Jones or designee Former Attorney General Brian Frosh Cumberland Mayor Ray Morriss “We have a president that treats our democracy with utter contempt. We have a Republican party that is trying to rig the rules in response to their terrible polling,” said Sen. Alsobrooks. “Let me be clear: Maryland deserves a fair map that represents the will of the people. That’s why I’m proud to chair this commission. Our democracy depends on all of us standing up in this moment.” Will Maryland’s First District finally be competitive? Can we at long last replace “AWOL Andy” Harris? Stay tuned….

In strong numbers, local residents turned out last month for a community information session on offshore wind hosted by the Alliance for Offshore Wind at the Ocean Pines library. The forum heard from industry experts, environmental advocates, and labor leaders to discuss how offshore wind projects can support jobs, clean energy, and coastal resilience along Maryland’s Eastern Shore. Featured were Sam Saluto of Oceantic, Jim Strong of the United Steelworkers, Ron Larsen of Sea Ink Solutions, and Jim Brown of the Audubon Society, all of whom emphasized the long-term environmental and economic benefits of wind development off Maryland’s coast. Speakers outlined how the project, once completed, is expected to create hundreds of high-paying jobs, generate clean power for tens of thousands of homes, and reduce reliance on fossil fuels that cause pollution and coastal erosion. “The potential here is extraordinary,” said Saluto, highlighting Oceantic’s ongoing work to ensure safety and sustainability standards remain at the highest level. “We’re not just talking about wind turbines. We’re talking about revitalizing local economies and protecting the Shore’s way of life.” Union representative Jim Strong echoed that sentiment, noting that Maryland’s labor community sees offshore wind as a chance to rebuild domestic manufacturing capacity while giving workers access to strong wages and long-term stability. Environmental voices, including Jim Brown of the Audubon Society, focused on how properly sited wind projects can reduce carbon emissions while coexisting with marine wildlife and migratory bird patterns. While most of the evening centered on data and community questions, the event briefly turned tense when Ocean City Mayor Rick Meehan, who is leading a lawsuit challenging Maryland’s offshore wind plans, attempted to question the panel. The mayor appeared to lose his train of thought mid-sentence and later cast doubt on the reality of climate change, drawing visible concern from several attendees. Meehan, a New Yorker who moved to Ocean City in 1971 and has held public office since 1985, has become one of the region’s most vocal opponents of offshore wind. His critics argue the lawsuit represents an effort to stall progress rather than engage with the facts presented by energy, labor, and environmental experts. Despite the brief exchange, the overall tone of the evening was forward-looking. Residents lingered after the formal discussion to review informational materials, speak with industry representatives, and learn about opportunities for community involvement. For many, the message was clear: Maryland’s transition to clean energy is not only feasible, it’s already underway, and the Eastern Shore stands to benefit.
