The federal agency says it will mandate randomized, controlled clinical trials for vaccination of younger, healthy individuals
It’s been a confusing past few weeks in terms of what the general public’s access to COVID-19 vaccinations will be like in the future.
Public health experts have been verbally jousting with the federal Department of Health and Human Services (HHS) about moves its health officials made recently regarding the vaccines. This could put clinical laboratories on the front lines to help determine whether COVID cases—particularly severe ones—eventually rise as a result.
Food and Drug Administration (FDA) commissioner Martin A. Makary, MD, MPH, and Vinay Prasad, MD, MPH, who leads the agency’s vaccine oversight, announced on May 20 that the agency will require randomized, controlled clinical trials before approving COVID vaccines for healthy individuals under age 65.
“While all other high-income nations confine vaccine recommendations to older adults (typically those older than 65 years of age), or those at high risk for severe COVID-19, the United States has adopted a one-size-fits-all regulatory framework and has granted broad marketing authorization to all Americans over the age of 6 months,” Makary and Prasad wrote in NEJM.
Under the new framework, they noted, the agency expects that it will continue to approve vaccines for adults over 65 as well as younger people with health conditions that put them at high risk of severe outcomes from COVID-19.
The range of diseases is “vast, including obesity and even mental health conditions such as depression,” they wrote. “Estimates suggest that 100 million to 200 million Americans will have access to vaccines in this manner.”

Former CDC APIC Member Pushes Back
The announcement drew criticism from public health and medical experts.
“The FDA guidance presented in the NEJM was not released in the Federal Register, did not invite comment, and provided only a general outline for COVID-19 vaccine licensure,” wrote pediatrician and vaccinologist Kathryn M. Edwards, MD, in a commentary for STAT. Edwards is a former member of the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP), which makes vaccine recommendations to the agency.
On June 9, in an opinion piece for The Wall Street Journal, HHS Secretary Robert F. Kennedy Jr. announced that he’s removing all 17 current members of ACIP.
“The FDA mandate is to ensure safe and effective vaccines based on the clinical studies performed, but not to develop specific recommendations for their use,” Edwards added. “Providing recommendations on vaccine use for the civilian population is the mandate of the ACIP.”
Edwards contended that extensive data is already available on the safety and effectiveness of COVID-19 vaccines. She stated that “there is no precedent for mandating continued placebo-controlled randomized clinical trials for vaccines that have already been licensed.”
New Policy Announcement Raises Questions
The New York Times notes that many questions remain about the specifics of the new policy and how broadly the vaccines will be available.
A likely scenario, the paper reported, is that health insurers will play a role as “gatekeepers by demanding medical documentation of an underlying condition before agreeing to cover the cost.” Without insurance coverage, people would likely pay approximately $140 per shot out of pocket.
This stands in contrast to European countries, where outreach campaigns target specific populations based on public health recommendations. according to Forbes. However, “in virtually all instances, COVID-19 vaccines can be gotten free of charge across Europe regardless of health or age status,” the article notes.
In their NEJM commentary, Prasad and Makary noted that adoption of the annual COVID-19 booster shot is already low. The CDC reported that 23% of Americans 18 and older received vaccinations in the 2024-2025 season, up slightly from 21.6% in 2023-2024.
Kennedy Steps In
On May 27, Kennedy announced in a video on X that the CDC would remove the COVID-19 vaccine from the recommended immunization schedule for healthy children and healthy pregnant women. Previously, the CDC recommended the vaccine for everyone ages six months and older.
Kennedy was joined in the video by Makary and National Institutes of Health director Jay Bhattacharya MD, PhD.
However, CDC staffers were “blindsided” by the announcement, NPR reported, citing an agency official who requested anonymity.
“Hours after the post on X, CDC staffers received a directive from Secretary Kennedy—dated May 19, but sent May 27—rescinding the department’s 2022 acceptance of the CDC’s recommendations for the use of COVID shots in children and during pregnancy,” NPR reported.
It now appears that HHS has at least partially backtracked on Kennedy’s announcement.
The CDC’s immunization schedule now states that vaccination of healthy children should be a matter of “shared clinical decision-making” between the doctor and parent or patient.
“After confusing, mixed messages from leaders at HHS earlier this week, we are relieved to see today that the CDC updated its schedules for child and adolescent immunizations to allow families to maintain the choice to immunize their children against COVID in consultation with their doctor,” American Academy of Pediatrics president Susan Kressly said in a statement from the organization.
In a June 1 interview with the CBS News program “Face the Nation,” Makary confirmed that the recommendation to vaccinate “should be with the patient and their doctor.”
However, he also criticized ACIP as a “kangaroo court where they just rubber stamp every single vaccine put in front of them.”
CAP president maintains medical laboratory staff are ‘indispensable’ in pandemic fight and should be in ‘top tier’ for vaccination
As COVID-19 vaccinations continue to roll out, the College of American Pathologists (CAP) is lobbying for clinical pathologists and medical laboratory staff to be moved up the priority list for vaccinations, stating they are “indispensable” in the pandemic fight.
In a news release, CAP’s President Patrick Godbey, MD, FCAP argued for the early vaccination of laboratory workers, “It is essential that early access to the vaccine be provided to all pathologists and laboratory personnel,” he said. “Pathologists have led throughout this pandemic by bringing tests for the coronavirus online in communities across the country and we must ensure that patient access to testing continues. We must also serve as a resource to discuss the facts about the vaccine and answer questions patients, family members, and friends have about why they should get the vaccine when it is available to them.”
In a phone call following a virtual press conference, pathologists and CAP President Patrick Godbey, MD (above), told MedPage Today that even if medical laboratory staff are not directly in contact with patients, they should be considered “top tier” (designated as Phase 1a) for getting the vaccine. “I think they [clinical laboratory workers] should be considered in the same tier as nurses,” said Godbey, who also is Laboratory Director at Southeastern Pathology Associates and Southeast Georgia Health System in Brunswick, Ga. “They’re indispensable. Without them, there’d be no one to run the tests.” (Photo copyright: Southeast Georgia Health System.)
Who Does CDC Think Should Be First to Be Vaccinated?
According toThe New York Times (NYT), there are an estimated 21 million healthcare workers in the United States, making it basically “impossible,” the NYT wrote, for them all to get vaccinated in the first wave of COVID-19 vaccinations.
A December 11, 2020, CDC Morbidity and Mortality Weekly Report, titled, “ACIP Interim Recommendation for Allocating Initial Supplies of COVID-19 Vaccine—United States, 2020,” notes that “The [federal] Advisory Committee on Immunization Practices (ACIP) recommended, as interim guidance, that both 1) healthcare personnel and 2) residents of long-term care facilities be offered COVID-19 vaccine in the initial phase of the vaccination program.”
The ACIP report defines healthcare personnel as “paid and unpaid persons serving in healthcare settings who have the potential for direct or indirect exposure to patients or infectious materials.”
However, a CDC terminology guidance document listed at the bottom of the ACIP report states, “For this update, HCP [Healthcare Personnel] does not include dental healthcare personnel, autopsy personnel, and laboratory personnel, as recommendations to address occupational infection prevention and control (IPC) services for these personnel are posted elsewhere.”
In part, the letter stated, “We are convinced that ACIP did not intend to exclude any healthcare workers from its recommendation to offer vaccinations to healthcare personnel in the initial phase of the COVID-19 vaccination program (Phase 1a). However, we would hate for jurisdictions to overlook dental, autopsy, and laboratory personnel because of a minor footnote in [CDC] guidance that was developed for an entirely different purpose (i.e., infection control).
“We respectfully ask CDC to clarify,” the letter continues, “… that all healthcare workers—including dental, autopsy, and laboratory personnel—are among those who should be given priority access to vaccine during the initial phase of the COVID-19 vaccination program.”
“In the laboratory, they are encountering and handling thousands of samples that have active live virus in them,” said Karger, who called clinical laboratory staff and phlebotomists the “forgotten” frontline healthcare workers. “We’re getting 10,000 samples a day. That’s a lot of handling of infectious specimens, and we do want [staff] to be prioritized for vaccination.”
Karger continued to stress the vital role clinical laboratories play not only in COVID-19 testing but also in the functioning of the overall health system. She added that staff burnout is a concern since laboratory staff have been working “full throttle” since March.
“From an operational standpoint, we do need to keep our lab up and running,” she said. “We don’t want to have staff out such that we would have to decrease our testing capacity, which would have widespread impacts for our health system and state.”
Testing for Post-Vaccine Immunity
The CAP panelists also highlighted the need to prepare for the aftermath of widespread COVID-19 vaccinations—the need to test for post-vaccine immunity.
“It’s not routine practice to check antibody levels after getting a vaccine but given the heightened interest in COVID testing, we are anticipating there is going to be some increased in demand for post-vaccine antibody testing,” Karger said. “We’re at least preparing for that and preparing to educate our providers.”
Karger pointed out that clinical pathologists will play an important role in educating providers about the type of antibody tests necessary to test for COVID-19 immunity, because, she says, only the SARS-CoV-2 spike protein antibody test will check for an immune response.
With the pandemic expected to stretch far into 2021, clinical laboratories will continue to play a crucial role in the nation’s healthcare response to COVID-19. As essential workers in the fight against infectious disease, clinical pathologists, clinical chemists, and all medical laboratory staff should be prioritized as frontline healthcare workers.
