Ocean County, a coastal region in central New Jersey, is home to some of the state’s most exclusive waterfront communities and its fastest-growing town, Lakewood.
A Republican bastion in a state controlled by Democrats, the county is largely suburban, encompassing more land than all but one other county in New Jersey.
Now, as the United States begins to chart a path through a third year of the pandemic, Ocean County also illustrates a stubborn public health challenge: A large share of its residents have not been vaccinated against the coronavirus, and its Covid-19 death rate is the highest in the state.
The county has recorded 459 virus-related deaths for every 100,000 residents, state data show. This outpaces fatality levels in every other county in New Jersey, an affluent, well-educated and densely populated state still struggling to limit its virus death rate. New Jersey has the fifth-highest fatality rate from Covid in the United States, behind Mississippi, Arizona, Alabama and West Virginia.
Explanations for the high number of deaths in Ocean County range include the large percentage of residents older than 85 and low vaccination rates among people 65 and under, a factor that some studies show is most closely tied to partisan politics.
The county also has a large and growing Orthodox Jewish population, who were hit hard during the first wave of the pandemic and whose vaccination rates are far lower than statewide averages, reflecting similar trends in Orthodox Jewish neighborhoods in New York.
In the 2020 presidential contest, when New Jersey supported President Biden by an overwhelming margin, voters in Ocean County backed former President Donald J. Trump by almost 29 percentage points — the largest share of any of the state’s Republican strongholds.
“At this stage of the game, whoever made the decision to get it has gotten it,” John G. Ducey, the longtime Democratic mayor of Brick, a 74,000-person Ocean County township, said about the vaccine.
“A lot of people who are not in favor of getting the vaccine make it on a political judgment,” he said, adding, “They don’t want an invasion of their bodies.”
Covid-19 vaccines have been proven to significantly lower the risk of serious illness or death, particularly for people who also have booster shots.
But among Ocean County residents eligible for a Covid-19 vaccine, only 58.4 percent have had at least two shots of Moderna’s or Pfizer-BioNTech’s vaccines or one shot of Johnson & Johnson’s, according to the Centers for Disease Control and Prevention. That is well below the statewide vaccination rate of 79.8 percent and the nationwide rate of 69.8 percent.
Lakewood, which is home to a thriving Orthodox Jewish community and is the county’s largest township, has the region’s lowest vaccination rates. Just 40 percent of Lakewood residents older than 5 are fully vaccinated; of these, 38 percent of residents eligible for a booster shot have received one, according to the state’s Department of Health.
In New York, Borough Park, a hub of Orthodox Jewish life in Brooklyn, has the city’s lowest vaccination rate. But it significantly outpaces Lakewood’s: About 53 percent of residents 5 and older in the Brooklyn neighborhood are vaccinated.
Most of Ocean County’s 2,925 confirmed and probable virus fatalities occurred in the first year of the pandemic, before vaccines or therapies to treat the disease were widely available. The average number of daily deaths, which peaked at 18 in May 2020, has now plummeted to about one a day.
Still, deaths have continued to accrue steadily: Since last spring, the number of people who have died each quarter in Ocean County has surpassed the number of fatalities during the three months before.
In Brick, where about 64 percent of residents eligible for Covid shots are vaccinated, roughly 28 percent of the 357 virus-related deaths occurred after vaccines became widely available, according to county data.
Still, Mr. Ducey said he opposed vaccine mandates.
“There’s people out there that do not want the vaccine and I think it should be left up to them,” said Mr. Ducey, who is vaccinated and has received a booster shot. “That’s the great thing about our country: We have freedom of choice.”
But as the worst days of the pandemic fade from memory and politicians plot a road toward normalcy, persuading more people to be vaccinated has become a priority for infectious-disease specialists like Dr. Meg Fisher, a pediatric immunologist working as a consultant to New Jersey’s health commissioner.
For them, nudging vaccination rates higher is considered vital to protect the broader community against new variants, like the highly transmissible Omicron subvariant, BA.2, which is now the dominant version of the coronavirus in the United States and around the world.
“Overcoming people’s complacency — this becomes very important right now,” Dr. Fisher said.
“We need the younger people vaccinated,” she added.
A nationwide study by the Pew Research Center found that 73 percent of people who identified as Democrats and were eligible for a booster shot had one, compared with 55 percent of the people surveyed who said they were Republicans. Younger Republicans were particularly hesitant to be vaccinated, the study showed, with just 52 percent of people between the ages of 18 and 29 reporting being vaccinated, compared with 88 percent of Democrats in the same age group.
“The biggest gap we’ve seen that’s been consistent has been partisanship,” said Alec Tyson, the associate director of research at Pew Research Center.
“It’s not narrowing,” he added. “If anything it’s growing even wider.”
Ocean County, which hugs the Jersey Shore and is a retirement destination, has the fourth-highest percentage of residents older than 85 in the United States, behind three similarly large counties in Florida, census data show. At one county hospital, Community Medical Center, 73 percent of patients qualify for Medicare, the federally funded health care available to people 65 and older and some younger people with disabilities.
“When you put that in perspective, it’s not that much of a surprise that the death rate would be high,” said Patrick Ahearn, chief executive of the medical center in nearby Toms River.
Daniel Regenye, Ocean County’s chief health officer, said his office created an extensive network of vaccination sites; none of the county’s 649,000 residents lives more than two miles from a location offering Covid vaccines, he said.
The county’s low vaccination rates do not apply to all age groups. Among people over 65, who are considered most vulnerable to severe disease, 88 percent are vaccinated, just six percentage points lower than the statewide rate.
Dimitri Svarnas and his wife, Janis, are registered Republicans who are ardent supporters of Mr. Trump.
The couple got vaccinated to take cruises and travel out of the country but were still deciding about booster shots.
“You can’t control my body,” Mr. Svarnas, 76, of Brick, said outside the ShopRite where he was first vaccinated last year. “Nobody controls my body.”
To entice younger people, Ocean County has run pop-up clinics that have dangled incentives like free admission to Six Flags Great Adventure, an amusement park in Jackson, and season-long access to the park’s popular safari ride.
In Lakewood, where nearly half of the residents are younger than 18, shots were offered during events held on Sundays that featured children’s bounce houses, free food and mini golf.
“There’s a general perception — and it’s being fed by a lot of people — that says natural infection is better,” Mr. Regenye said.
“My concern is a resurgence of vaccine-preventable disease,” he added.
