The COVID-19 public health emergency is over. What happens now?

May 2023 was a landmark month for COVID-19. On May 5—1150 days after the initial pandemic declaration1—the World Health Organization (WHO) International Health Regulations (IHR) Emergency Committee lifted the Public Health Emergency of International Concern.2 Six days later, the federal Public Health Emergency (PHE) declaration in the United States ended, marking the end of a tumultuous era that began in late 2019.3

The global risk for COVID-19 remains high, but “there is evidence of reducing risks to human health, driven mainly by high population-level immunity from infection, vaccination, or both,” according to the IHR committee.2 Those reduced risks, coupled with a significant global decline in weekly deaths, hospitalizations, and intensive care unit admissions, suggest that currently circulating variants are not associated with severe disease. Although management of this novel respiratory pathogen—which once required daily government briefings—has become an established and ongoing part of everyday life, “that does not mean COVID-19 is over as a global health threat,” Tedros Adhanom Ghebreyesus, PhD, director-general of the WHO, said.4 As the SARS-CoV-2 virus continues to circulate, new variants may emerge,4 coupled with spikes in cases—and perhaps exacerbated by a vacuum of federal- and state-level disease mitigation guidance.

Across the US, the conclusion of the public health emergency signals a shift in the way pharmacists, health care providers, and federal agencies are looking at COVID-19. Vaccines, treatments, and testing will still be available to the public,3 and pharmacists can administer vaccines through the end of 2024, thanks to an amendment to the Public Readiness and Emergency Preparedness (PREP) Act implemented by the US Department of Health and Human Services (HHS).5 This month, Drug Topics takes a deeper look at the evolution of the pandemic, from the first reported cases to the end of the public health emergency—and beyond.

Taking on COVID-19

Pharmacists were instrumental in ensuring the health of their communities during the pandemic. Between February 2020 and September 2022, pharmacists and other pharmacy team members administered millions of COVID-19 tests and vaccines, “plausibly account[ing] for more than 50% of COVID-19 vaccinations in the United States,” wrote John D. Grabenstein, PhD, RPh, president of Vaccine Dynamics, in a 2022 article published in the Journal of the American Pharmacists Association.6

Pharmacists were given the go-ahead to administer FDA-authorized COVID-19 tests on April 8, 2020. Between May 2020 and May 2022, more than 14,522 Clinical Laboratory Improvement Amendment waivers were granted to pharmacies. In September 2021, pharmacists were authorized to order and administer certain COVID-19 therapeutics.6

The Federal Retail Pharmacy Partnership was launched in November 2020, enabling the “rapid rollout” of COVID- 19 vaccines beginning the following month.6 In early 2021, updated vaccination plans from the White House prominently featured community pharmacists, alongside their chain pharmacy colleagues, as COVID-19 vaccine providers.6 To date, more than 303 million COVID-19 vaccines have been administered through this program (See Figure 1 for more COVID-19 by the numbers).7 Pharmacists were also responsible for administering nearly 88 million influenza vaccine doses during the 2020-2021 and 2021-2022 flu seasons combined.

The federal Test to Treat initiative created an additional opportunity for pharmacists to provide care.6 In March 2022, a network of clinics and pharmacists was assembled to accelerate public access to antiviral medications. As of the end of 2022, these single-stop, test-to-treat sites were active in more than 2000 pharmacy-based clinics and Health Resources and Services Administration–supported federally qualified health centers.6

Amending the PREP Act

On April 14, 2023, HHS Secretary Xavier Becerra announced that pharmacists continue to use the extended authorities granted to them through the PREP Act through the end of 2024.8 “Over the past 3 years, the PREP Act declaration has provided liability protection to manufacturers, distributors, and other organizations conducting countermeasure programs and providers administering COVID-19 countermeasures,” an HHS news release stated.9

The Eleventh Amendment to the PREP Act5 was released on May 11, 2023—the same day the PHE expired. And as promised by Becerra, the updated declaration extended coverage for administration of COVID-19 tests and vaccines, as well as seasonal influenza vaccines, to qualified pharmacists, pharmacy interns, and pharmacy technicians through the end of 2024—regardless of any government agreements or emergency declarations. “Extending the time period for PREP Act coverage…allows for continued access,” the declaration noted. “Licensed pharmacists, pharmacy interns, and qualified pharmacy technicians are well positioned to provide continued access to covered countermeasures, particularly in certain areas or for certain populations that have too few primary care providers, or that are otherwise medically underserved.”5

The amendment does end the ability of pharmacists to vaccinate against COVID-19 across state lines, and it no longer extends coverage to routine childhood vaccinations. An April 2023 news release from HHS outlined other key features that will not change under the amended PREP Act declaration, including continued liability immunity for pharmacists, pharmacy interns, and pharmacy technicians prescribing or dispensing oral antiviral COVID-19 treatments, and continued coverage of the Test to Treat initiative.10

Ending the PHE

On May 9, 2023, HHS released a Fact Sheet with information on the end of the COVID-19 PHE, including updates on the current flexibilities empowered through the emergency declaration.9

Vaccines and Treatments. The CDC’s COVID-19 Vaccination Program Provider Agreement ensured individuals in the US would have continued access to COVID-19 vaccines at no cost. However, “once the federal government is longer purchasing or distributing COVID-19 vaccines and treatments, payment, coverage, and access may change,” the fact sheet stated.9 Government partners continue working to ensure a smooth transition for the provision of COVID-19 vaccines and certain COVID-19 treatments to the traditional health care market.

For most individuals with private insurance, COVID-19 vaccines are considered a preventive health service and will be fully covered without a co-pay when administered by an in-network provider.9 For those without insurance, the HHS Bridge Access Program, which was announced on April 18, 2023, will help maintain broad access to vaccines and treatments. Medicaid will continue coverage of COVID-19 vaccinations without a co-pay or cost sharing through September 2024.9

Out-of-pocket expenses for COVID-19 treatments such as nirmatrelvir-ritonavir (Paxlovid) and molnupiravir (Lagevrio) may change based on individuals’ health coverage. Medicaid programs will continue to cover these treatments through September 2024.9 Emergency use authorizations for COVID-19 products—a list that includes tests, vaccines, and treatments—will not be affected by the end of the PHE, nor will the FDA’s ability to authorize necessary products for emergency use.9

Telehealth Flexibilities. Most Medicare telehealth flexibilities used by individuals with Medicare will not be changed through December 2024.9

COVID-19 Testing. Individuals with Medicare and Medicaid Advantage plans can continue to receive polymerase chain reaction and antigen tests, although Medicaid Advantage cost sharing may change. State Medicaid programs must provide coverage without cost sharing “until the last day of the first calendar quarter that begins 1 year after the last day of the COVID-19 PHE”—in other words, through September 2024, according to the fact sheet.9

Requirements for private insurance companies to cover COVID-19 tests without cost sharing will end. Coverage may continue on a plan-by-plan basis, and private insurers are encouraged to keep providing this free coverage.9 The federal government may also continue to distribute free COVID-19 tests from the Strategic National Stockpile through its partners.

Data Reporting and Surveillance. HHS will no longer have the authority to require COVID-19 laboratory test reporting data, which will affect negative test result reporting and the ability to calculate COVID-19 percent positivity. Hospital data reporting will continue as required by CMS.9 The CDC will continue to report data on COVID-19 hospital admissions, deaths, emergency department visits, test positivity, wastewater and genomic surveillance, number of vaccines administered, and percentage of COVID-19 related deaths.9

Long COVID: Where Do We Go From Here?

With the recent WHO announcement that the COVID-19 pandemic is no longer considered a global health emergency, many individuals may think they no longer need to worry about COVID-19. However, symptoms of a SARS-CoV-2 infection often go far beyond the initial infection.

It is estimated that nearly 1 in 8 individuals have post–COVID-19 conditions (PCC), otherwise known as long COVID—a complex condition involving multiple organ systems. It can present in many ways, including chest pain, difficulties breathing, muscle pain, ageusia or anosmia, alternating feeling hot and cold, and general tiredness.12

A new study has found the risk of long COVID and its associated symptoms across diverse populations.13 Results of the research, which was led by investigators from Weill Cornell Medicine and NewYork-Presbyterian Medical Center, were published in Nature Communications.

“Long COVID is a new disease that is very complicated and quite difficult to characterize,” said Chengxi Zang, an instructor in population health sciences at Weill Cornell Medicine and the study’s lead author. “It affects multiple organs and presents a severe burden to society, making it urgent that we define this disease and determine how well that definition applies among different populations.”14

Investigators developed a high-throughput computational screening pipeline to identify potential PCC symptoms and signs using electronic health records. Data were gathered from the INSIGHT network, which covers 11 million patients in the New York, New York, metropolitan area, and the OneFlorida+ network, which covers 16.8 million patients in Florida, Georgia, and Alabama.13

The study cohort included 35,275 adult patients from New York and 22,341 from Florida with lab-confirmed SARS-CoV-2 infection who survived the first 30 days post infection from March 2020 to November 2021. The cohort included 326,126 noninfected control patients from New York and 177,010 from Florida. Eligible patients were required to have at least 1 diagnosis record within 3 years to 1 week before the index date, and at least 1 diagnosis record within 30 days to 180 days after the index date.13

Investigators found that potential PCC diagnoses identified through the INSIGHT cohort were higher than in the OneFlorida+ cohort. In the INSIGHT cohort, rates of pulmonary fibrosis and thromboembolism were 50% higher. Additionally, 38 diagnoses and 59 medications were identified as potential PCCs in the INSIGHT cohort, compared with 11 diagnoses and 9 medications in the OneFlorida+ cohort.13

They noted that there were various possible reasons for the observed differences, including that patients in the Florida cohort were younger and more socially disadvantaged on average. Socially disadvantaged patients may be less likely to present for care during the relatively short postacute phase, leading to an undercount of potential PCC conditions and medication use, the investigators said. There were also many common conditions across both cohorts, such as dementia, hair loss, pressure ulcers, dyspnea, chest pain, abnormal heartbeat, malaise, and fatigue.13

“In this new research, we examined a broad list of potential long COVID conditions one by one,” said Fei Wang, PhD, an associate professor of health care policy and research at Weill Cornell Medicine and one of the study authors. “These findings can help us better recognize the broad involvement of multiple organ systems in long COVID, and design appropriate plans for patient management and treatment development.”14

Day by Day: A Pandemic Timeline

Rapid changes in policies, procedures, and protocols—as well as in our understanding of the SARS-CoV-2 virus itself—were commonplace during the early days of the COVID-19 pandemic.
