'We're Absolutely Making It Too Hard': The Complexity Of Adult Immunization Delivery Hinders Vaccine Uptake
Alison Buttenheim was floored by a sign she saw in her doctor's office when she went to get the first jab of the two-dose shingles vaccine to protect her against painful flare-ups of varicella zoster.
"Medicare patients cannot receive Tdap or zoster vaccines here. They need to obtain [them] at their pharmacy. If they receive it here, they need to pay out of pocket," the notice read.
Medicare patients could get flu shots, Covid-19 shots, and vaccinations to protect against pneumonia in that office. And they could probably actually get the Tdap vaccination (it protects against tetanus, diphtheria, and pertussis) if they had stepped on a nail or had some other accident that could lead to tetanus infection — in other words, if they needed it as a treatment. No dice, though, if they were doing what all adults are actually supposed to do: Get a tetanus booster every 10 years to maintain protection against the dangerous bacteria, which kills 10% to 20% of people infected.
Buttenheim is a professor of nursing at the University of Pennsylvania who studies vaccine acceptance and hesitancy. She knows that any amount of difficulty in the immunization process can deter people from getting vaccinated. She couldn't believe her eyes.
"Really? It's different for Medicare and non-Medicare — which is common — and it's different by shot?" she said, explaining her incredulity in a recent interview with STAT. (Buttenheim is old enough to qualify for the shingles shot but not old enough to qualify for Medicare. She got the vaccine in her doctor's office without having to pay.)
The sign Buttenheim saw neatly illustrates the complexity of the burgeoning field of adult immunizations. In recent years, the number of vaccinations adults are being asked to get has expanded substantially. As a result, keeping track of which vaccines are recommended — and avoiding paying for them out of pocket — has grown increasingly convoluted.
To stay abreast of what to get and when and where to get it almost requires would-be vaccine recipients to have advanced degrees. Buttenheim has a couple — and yet she recently found herself shelling out $160 for her latest Covid booster. She wanted to get it before attending a conference, but the only place she could nab an appointment — at an independent pharmacy — wasn't in her insurance network.
She thinks she might be able to get the money back if she jumps through some insurance company hoops, but knows from her research that barriers like these deter a lot of people from keeping up to date on immunizations.
"We're absolutely making it too hard," Buttenheim said of the current patchwork system for adult vaccination.
Adult immunization rates are perennially suboptimal. Fewer than half of adults in the U.S. Get a flu shot. Only about 1 in 5 adults got a Covid booster in 2022; even among the highest-risk group, adults 65 and older, only 43% got last fall's Covid shot. The Centers for Disease Control and Prevention estimated that in 2019, only 22% of adults were up to date on all the vaccines they should have received.
Some of that may be due to vaccine hesitancy but more of it is likely due to the sheer difficulty of knowing what to get, when to get it, and how to get insurance coverage for the various shots, said Saad Omer, a vaccine expert who is dean of the Peter O'Donnell Jr. School of Public Health at the University of Texas Southwestern.
Omer said that when he thinks about vaccination policy, he is reminded of his adult nieces. They got Covid boosters last fall, but a couple of months after the shots became available. The delay wasn't due to concerns about vaccines. It was just that vaccination — any vaccination — isn't top of mind for them. And they are not alone, he said.
"Beyond the cacophony of pro-vaccine and anti-vaccine arguments on Twitter, most of the country doesn't actively think about vaccines, period," said Omer.
To get people like Omer's nieces to actively engage in immunization programs, the systems need to be "super easy" to navigate, he said.
But that is not the current reality, as Americans have been finding out this fall as they've struggled to book appointments for Covid shots and battled with insurance companies over coverage of the new RSV vaccine.
Buttenheim agreed, saying that some people are eager to stay up to date on their vaccinations while others won't take any vaccines, no matter what. But the majority of people are somewhere in between — open to the idea, but not so motivated that they'll follow through if they encounter access or cost hurdles. "There's just a really big group where just the littlest amount of uncertainty and friction is going to … bump you to not getting it," she said.
There was a time when adults were mostly just advised to get tetanus and flu shots. No longer. Adults — especially older adults — are urged to get shingles shots and Covid jabs and pneumococcal vaccines, and the new immunizations to protect against respiratory syncytial virus, or RSV.
There has been a proliferation, too, of the number of vaccines recommended for pregnant people, to protect them during pregnancy or their baby after birth. The list now includes influenza, Covid, hepatitis B, Tdap, and RSV vaccines, the latter only if the baby is to be born between October and March.
Pregnant people can and should get these vaccinations from their obstetrician-gynecologists, where they should not be asked to pay out of pocket. OB-GYNs have a narrow window in which to administer the full slate of immunizations — if the pregnant person agrees to accept them all.

The delivery picture for non-pregnant adults is more complex still, a reflection of a combination of factors. Many adults don't have a primary care provider, or have a hard time getting in to see their PCP if they do. "It's like, 'Great, we can see you in three months,'" said Rupali Limaye, a behavioral and social scientist who studies vaccine acceptance and hesitancy. "You've missed flu season."
Unless they are ill, many adults interact infrequently with the medical establishment. When they do, they may get care in a variety of places — making it no one person's job to ensure they are up to date with their vaccinations. That's a far cry from what happens with children, who have well-child visits mapped across the timeline of their childhoods that are deliberately synced to when they should be getting one or some of the myriad vaccine doses kids are supposed to receive.
"You know what you're there for. You're there for your vaccines," said Helen "Keipp" Talbot, an infectious diseases expert at Vanderbilt University, said while taking part in a panel discussion during STAT's Future Summit earlier this fall. "We don't have anything like that in the adult world."
Furthermore, for the most part, kids get their vaccines in that single setting, allowing for easy record keeping. Again, not the case with adults.
"Adults get vaccines in like 30 different places — at their employer or a pharmacy that they just go to. And I think the fact that we don't have a system where all of that is captured, it does increase the complexity of knowing who's received what," said Helen Chu, an infectious diseases specialist at the University of Washington.
The use of pharmacies to deliver adult vaccinations is a relatively new phenomenon, the growth of which was turbocharged by the Covid pandemic. It has undeniably created immunization opportunities that didn't exist before. Buttenheim got her flu shot on Aug. 31 — earlier than she had planned to — because she was in a pharmacy and the pharmacist effectively wouldn't take no for an answer.
"I think pharmacies would argue, correctly: 'We're much more likely to see these folks than a physician is. We're a touch point that has a much higher frequency than a physician's office.' So that's great," she said.
But delivering multiple types of vaccines adds a whole new layer of complexity to the jobs of busy pharmacists. Some vaccines shouldn't be given together if it can be avoided, because the response to one could dampen the response to another. (It's been shown that RSV vaccines weaken the response generated by the pertussis component of Tdap, for instance.) In other cases, some vaccines are sufficiently reactogenic — meaning they carry a kick — that getting them in combination could make for an unpleasant day or two following injection.
"Shingrix is a great vaccine. It's really, really effective. And shingles is a pretty morbid illness for older adults, so it's great that it exists. But with an … adjuvant," — a compound that amplifies the impact of the vaccine — "you're not going to give it at the same visit as your GSK RSV [vaccine]," Chu said, because it also contains the same adjuvant.
Because there is no fixed schedule, as there is with childhood vaccines, adults often have to figure this stuff out themselves. The second dose of shingles vaccine should be given no sooner than two months after the first, but no later — in theory — than six months after dose 1. Buttenheim asked her doctor's office to send her an electronic reminder to book an appointment when she was due for her second shingles shot. She was told they didn't do that.
"I'm a behavioral scientist. Give me a cue to action here," she said. Buttenheim ended up getting the second shingles shot a year minus a day after the first dose.
Adults are eligible for the shingles vaccine once they hit the age of 50, and for the pneumococcal vaccine when they reach the age of 65. But where kids have doctor visits before school entry — when final doses of some vaccines are given — adults don't typically have medical appointments timed to specified ages. "We just don't have those kinds of built-in cues and default milestones that we do for the childhood schedule," Buttenheim said.
Then there's the issue of seasonal versus non-seasonal vaccines. Some adult vaccines are one-offs — a single shot like the pneumococcal vaccine or, in the case of shingles, two doses. But other vaccines are given annually, in a particular time frame — flu and Covid shots, for instance, in the lead up to cold-and-flu season. The RSV vaccines for seniors are so new it's not yet known how frequently they will need to be administered, or what the impact on overall protection would be of administering Covid plus flu plus RSV in one session.
How do you coordinate all these shots? Do you have to wait a certain interval after having one type of vaccine before you can have another? Can you get other vaccines in the gap between the first shingles shot and the second?
This is complicated stuff — even for people well versed in vaccines. "I can interpret the info, but it doesn't live inside my head. I have to go and search for it," Buttenheim said.
A lot of people may struggle to find, let alone interpret, the necessary information.
"I think for most people, it is too much. It is too much mental bandwidth to figure this out," said Limaye, who is an associate professor in the Johns Hopkins Bloomberg School of Public Health. "I think the majority of our issues here in the U.S. — I think, yes, we do have hesitancy, absolutely — but I think a lot of them just have to do with access and availability. That's it."
Then there are issues around payment.
The payment piece should be simple because U.S. Health insurers are required to pay for vaccines that have been recommended by the Advisory Committee on Immunization Practices, which guides the CDC on vaccine use. The vaccines we're talking about here have all been recommended by the ACIP. But when a vaccine is newly added to the recommended list, insurers have up to a year to start to cover the cost. Some take their time, as a number of people who tried to get an RSV shot this fall found out to their dismay.
Even insurers that add a new vaccine quickly may have restrictions on where the people they cover can get immunized. Limaye's insurance pays for her vaccines if she gets them at a Hopkins pharmacy or at a Walgreens. If she books an appointment at a CVS, however, she'd end up having to pay for her shot.
There's a simple fix for this, Omer said. The Vaccines.Gov website that people can search to find appointments for Covid or flu shots could be programmed to ask users for health insurance details, and incorporate that information into the search results they are shown. Even better would be if the site linked individuals to their vaccine records to help remind them of the immunizations they are missing. "That would be the version 4.0," he said. "There seems to be some limitation of our imagination, even within the existing resources. It's not easy, but it's not nearly impossible."
UPCOMING EVENTWe're hosting events nationwide (and virtually) to tackle the biggest questions in health and medicine. Browse our upcoming events to see what's on the horizon.
For older adults who are on Medicare, there is a counterintuitive situation in which some vaccines are covered by one part of Medicare while others are covered by another. Medicare still covers the cost, but this divvying up of vaccines into Part B versus Part D coverage restricts which health professionals can get paid to administer particular vaccines — hence the sign that flummoxed Buttenheim in her doctor's office.
Part B covers influenza, pneumococcal, hepatitis B, and Covid-19 vaccines. They can be administered by a physician or a pharmacist, at no cost to the recipient. Other vaccines recommended for adults by the ACIP are covered by Part D. That includes the shingles shot, Tdap, RSV vaccines for adults 60 and older, and a range of other shots. Insurers must cover the cost of these vaccines too. But physicians have a difficult time claiming compensation for administering them, so often prefer not to stock them, leaving this work to pharmacies.
Not simple, but not super hard, right? But wait, there's more.
As mentioned earlier, Tdap is sometimes a Part B vaccine — if it's being given in response to a tetanus exposure risk — and sometimes a Part D vaccine. "It's 100% insane," Limaye said.
And while the RSV vaccine is a Part D vaccine — to be given by pharmacists — some states require people to first get a prescription from a doctor to give to the pharmacist, an irritating two-step procedure that adds friction to a process that does not benefit from anything that might act as a deterrent. Other states, like New York, have taken regulatory steps to allow pharmacists to give RSV vaccines without a prescription.
(Further adding to confusion about the RSV vaccines for seniors is the fact that the ACIP issued what is known as a "shared decision-making" recommendation for them. Anyone 60 and older can get one of the shots, but should have a discussion with a health professional about their individual risk and the potential side effects of the vaccine. This will dampen uptake of the vaccine, Chu predicted.
"I think a lot of people perceive that as a hedge," she said. "I think it makes you think that the CDC is saying, 'Well, you should get this vaccine, but you need to talk to your doctor about all the risks and the benefits and all these rare side effects that we saw, and all of these other things.' And really, primary care physicians do not have time for this.")
To Limaye, the solution is obvious: Iron out the insurance reimbursement kinks.
"Honestly, if we really care about the health of the American people, all pharmacies should be able to offer all adult vaccines. Bottom line," she said, adding there should be no in-network/out-of-network deals between insurers and pharmacy chains.
"I think there has to be this recognition of meeting people where they are. Most people go to a pharmacy for something. Fewer people go to a doctor's office regularly. So that's why I would argue … the easiest and most widespread impactful solution is to have all adult vaccines available at a pharmacy."
Even if the issues around insurance reimbursement could be clarified, that wouldn't solve the problem of under-vaccinated adults, however. That's because a big chunk of American adults, an estimated 25 million, are not covered by private insurance, Medicaid, or Medicare.
For children in similar straits, there's a program called Vaccines for Children, which pays for vaccinations for kids who wouldn't otherwise be vaccinated. The CDC program covers a little over half of the country's children.
But there is no corresponding program for adults. President Biden's 2024 budget proposes to create a Vaccines for Adults program. (Some people in public health prefer the moniker Vaccines for All, with the goal of melding the two programs.) But presidents' budgets are wish lists; the prospects that a Republican-led House would greenlight spending expansion to cover more vaccinations seems unlikely in the current climate.
Not having such a program undermines the country's capacity to respond to health threats, Demetre Daskalakis, acting director of the CDC's National Center for Immunization and Respiratory Diseases, said during a recent panel discussion, pointing to the 2022 response to the mpox outbreak to illustrate his point.
In an attempt to quell the fast-growing outbreak, mpox vaccine was provided to at-risk individuals, at no cost, regardless of their insurance status. But some medical providers who see at-risk patients couldn't bill to claim compensation for their work, limiting the pool of people involved in vaccinating individuals and slowing the process of protecting the people at risk.
"The lack of compensation for uninsured meant that many providers couldn't implement mpox vaccination in their settings. A program like VFA would help address that," Daskalakis said in an email.
"In an ideal world, we would have simplified payment of vaccines, delivery of vaccines, and a Vaccines for Adults program," said Omer, who suggested that at the end of the day better uptake of vaccines would likely be cost-saving, because of the serious illnesses that vaccines can avert.
Why (and When) You Should Get Both A COVID Shot And A Flu Shot This Fall
The COVID shots of 2021—and even the bivalent booster you may have gotten recently—are no longer a great match for the strains of the virus that are going around. Fortunately, new versions of the vaccine will be available this fall. Flu shots are also still important, and RSV shots are available for the very young, for people who are pregnant, and for older folks. Here's your rundown on this fall's vaccines, and when you should get them.
What shots do I need and when?Fall is the beginning of flu season, and it's also when we see an uptick in other respiratory illnesses. To better protect yourself, you may want to get:
If you are pregnant, besides the RSV shot, the CDC recommends getting a flu vaccine, a COVID vaccine, and a pertussis vaccine (TDaP) in your third trimester. The baby will be born with antibodies to those diseases, protecting them for about the first six months of life.
What's different about the new COVID vaccine?The first generation of COVID vaccines used mRNA for the spike protein from the original flavor of the virus. Later, the bivalent boosters came out, using the original strain alongside the Omicron version. This year, the vaccines will use just one strain, this time the XBB variant. Eris, one of the dominant strains circulating right now, is a close relative of XBB.
The new COVID vaccines aren't on pharmacy shelves yet, but are expected to be available in late September 2023.
Can I get the vaccines at the same time?You can get multiple shots in the same appointment, although the CDC has recommended in the past that you get the COVID shot in one arm and your flu shot in the other if you're using one of the high-dose or adjuvanted flu shots (this applies to older adults, but not to middle-aged or younger people).
Otherwise, it's up to you. Each shot may result in a sore arm, so you might prefer to get both of them over with at once, or you might decide it's more convenient to stop by the drugstore one week for your COVID booster and the next week for your flu shot.
The CDC says that the RSV vaccine is safe to receive alongside COVID, flu, or other vaccines. If you're getting multiple vaccines, you may want to talk to your doctor or pharmacist about whether it makes sense to get them all together.
This post was originally published in August 2023 and was updated on Sept. 27, 2023 to include the information that there is now an RSV shot recommended during weeks 32-36 of pregnancy.
Pfizer, BioNTech Say Combo Flu, COVID Shot Met Goal In Study
Dive Brief:Makers of COVID-19 shots are fighting to protect sales as the pandemic recedes from public consciousness and prominent figures fuel vaccine skepticism. The companies see the future in combination vaccines, building on a tradition of relatively strong acceptance of yearly flu shots.
Like the flu, COVID-19 appears to peak in the fall and winter, making a vaccine that can fight both viruses at once a natural fit. There's also a long history of combination vaccines; the childhood vaccination schedule includes a shot for tetanus, diphtheria and acellular pertussis, as well as one that fights the mumps, measles and rubella.
Pfizer has already begun laying the groundwork for the idea of getting inoculated for both the flu and COVID-19 at the same time, recruiting Kansas City Chiefs tight end Travis Kelce for a "Two Things At Once" ad campaign. The Centers for Disease Control and Administration's website also emphasizes the safety and potential convenience of a double vaccine appointment.
Still, early trends this fall suggest that Americans are more willing to get a flu shot than one for COVID-19. For now, Moderna is sticking with an estimate of $6 billion to $8 billion in revenue from its COVID-19 shot for the year. That's down from about $18.4 billion in sales last year.
Pfizer, meanwhile, said in August that sales of its Comirnaty shot fell to $1.5 billion in the second quarter, compared with $8.8 billion a year earlier. Pfizer is also seeing less demand for its Paxlovid treatment for COVID-19, pushing the company to shave its overall revenue forecast for the year by $9 billion while making plans for cost cuts and layoffs.
