‘Pharmacy deserts’ may be contributing to Nevada vaccine inequities

‘Leaning on pharmacies’ isn’t going to cut it, researcher says

Earlier this month, the White House announced the Federal Retail Pharmacy Program for COVID-19 Vaccination, which will supply coronavirus vaccines directly to pharmacies nationwide.

Nevada, like other states, has followed a federal plan that leans heavily on large pharmacy chains Walgreens and Smith’s Pharmacy for the distribution of the vaccine. In Clark County only sites operated by the Southern Nevada Health District have administered more doses of the vaccines than the retail pharmacies. 

Researchers, however, warn a heavy reliance on pharmacies for vaccinations could leave low-income communities and people of color behind. 

In a report published in JAMA Internal Medicine, researchers found that from 2009 to 2015, one in four pharmacies located in urban, low-income neighborhoods shut down. Pharmacies with more uninsured or publicly insured residents with Medicare or Medicaid were two times more likely to close than other pharmacies.

Pharmacies get lower reimbursement rates for filling Medicaid and Medicare prescriptions, often contributing to the closure of stores in poorer neighborhoods, said Dima Qato, senior author of the study and associate professor of pharmacy at the University of Southern California.

Pharmacy closures contribute to the growth of “pharmacy deserts,” an area defined by limited access to pharmacies.

“Pharmacy deserts—which are more prevalent in minority communities—may definitely worsen existing disparities in Covid vaccination rates,” said Qato, Senior Fellow at Schaefer Center of Health Policy and Economics, in an email.

Inequities in Nevada

In Nevada, troubling patterns of inequality among those vaccinated have become clear in the states’ most populous counties.

In Clark County, only about 11 percent of vaccine recipients so far were Hispanic, despite making up about 32 percent of the county’s population. Black residents comprise close to 13 percent of the population but have only received about 5 percent of available vaccines, according to vaccination data published weekly by the Southern Nevada Health District. White and Asian people have received a share of vaccines comparable to their share of the county population.

County data also shows that ZIP codes with the highest rates of COVID-19 have some of the lowest frequency of vaccinations.

The Nevada State Immunization Program and the Board of Pharmacy have coordinated with Walgreens,  Smith’s Pharmacy, and Walmart to inoculate Nevadan seniors 65 and older. 

However, state data on vaccine frequency by residential ZIP code reveals inequity among some ZIP codes with fewer pharmacies.

The ZIP code with the highest frequency of vaccinations in Clark County 89052, which includes the affluent Seven Hills community, has four pharmacies receiving doses to vaccinate Nevada’s seniors. 

In contrast, one of the hardest-hit ZIP codes, 89115 in North Las Vegas, only has one pharmacy receiving and administering doses, and one of the lowest vaccination rates. Another hard-hit neighborhood with low vaccine frequency, the heavily Latino and Black ZIP code of 89101 in the heart of the Las Vegas metro area, similarly only has one pharmacy receiving doses.

Many other neighborhoods still are one mile or more from the nearest pharmacy administering vaccines, making it difficult for low-income residents without cars or the elderly to get vaccinated. 

In Nevada, some vaccines are being administered through grocery stores Smith’s and Walmart, however, the abundance of food deserts in Southern Nevada’s low-income communities contributes to inequity in vaccine sites.

State officials are analyzing disparities in vaccine distribution. Earlier this month, Gov. Steve Sisolak introduced his Equity and Fairness Initiative, an effort meant to ensure a more equitable distribution of doses. The state’s immunization team also created an equity task force in conjunction with the Nevada Minority Health & Equity Coalition.

Immunize Nevada, a partner of the Nevada Minority Health & Equity Coalition, has looked at ZIP code level data over the years and found that there are ZIP codes where residents, especially children, don’t have access to providers for immunizations.

“We’ve known based on immunization data that we absolutely have vaccine disparities and inequities in Nevada, but a look at vaccine distribution so far brings it to a more urgent level,” said Heidi Parker, executive director of the non-profit organization Immunize Nevada.

Immunize Nevada and the Nevada Minority Health and Equity Coalition have formed the Nevada Vaccine Equity Collaborative to seek input from community members on barriers to access. 

“We need to ensure that we are looking at that data for this and if there is not a pharmacy or other providers who are providing vaccines in that area we absolutely want to make sure that’s on the radar,” Parker said.

The problem with ‘leaning on pharmacies’

Not all ZIP codes with low vaccine rates in Nevada are lacking in pharmacies, but states should continue to monitor vaccine distribution in communities that lack pharmacies, said Tori Marsh, director of research at GoodRx, a health care data and digital products firm.

“Leaning on pharmacies is not going to be sufficient in terms of equally vaccinating everyone across the country because there are discrepancies in where these pharmacies are located,” Marsh said.

Vaccine deserts threaten to prolong COVID-19 vaccine rollout and widen disparities, according to new research from GoodRx. Nevada’s two most populous counties, Clark and Washoe, are on the low end of available pharmacies compared to counties with similar populations, according to study, which is based on analysis of data from the Centers for Disease Control, the National Council for Prescription Drugs and the Census Bureau’s American Commnity Survey.

“If we’re going to rely on pharmacies that are unevenly distributed what are some of these areas that would benefit from additional sites and some additional support like mobile clinics and mass vaccination clinics,” Marsh said.

In Clark County, the most populous county in the state, there are 1.59 pharmacies per 10,000 people while in Washoe County, the second-most populous county, there are 1.54 pharmacies per 10,000 people.

Lincoln County — just south of Clark County — with a population of about 5,300 on the other hand, has 3.74 pharmacies per 10,000 people.

Nevada had a rough start to vaccine distribution, consistently ranking among the worst states at distributing and administering doses per capita, but has significantly improved.

By contrast in West Virginia’s most populous county— a state widely applauded for its vaccine rollout— there are 2.9 pharmacies per 10,000 people and a majority of counties have more than two pharmacies per 10,000. The state also chose not to partner with pharmacy chains, instead opting for a network of independently owned pharmacies, which the state credits for its robust vaccine rollout.

As vaccines become more widely available in the coming months, Walgreens, a federal partner in vaccine distribution in Nevada, has pledged to go into more than 100 communities across the country with COVID vaccine clinics in response to inequity as part of their COVID vaccine equity initiative, said Kris Lathan, a spokeswoman for Walgreens, in an email.

“Addressing pharmacy deserts is central to our efforts to drive health equity,” said Lathan.
