Theo, an 18-month-old in rural Nebraska, walks with his father in their backyard. For many toddlers, the barriers to accessing COVID-19 vaccines are many, such as few locations giving vaccines to very young children.
It’s Theo’s* first time in the snow. Wide-eyed, he totters outside holding his father’s hand. Sarah Holmes feels great joy in watching her 18-month-old son experience the world, “His genuine wonder and excitement gives me so much hope.”
In the summer of 2021, two months after Theo was born, Holmes, a behavioral health provider in Nebraska lost her grandparents to COVID-19. Both were vaccinated and thought they could unmask without any risk. “My grandfather was a veteran, and really trusted the government and faith leaders saying that COVID-19 wasn’t a threat anymore,” she says.” The state of emergency in Louisiana had ended and that was the message from the people they respected. “That is what killed them.”
The current official public health messaging is that regardless of what variant is circulating, the best way to be protected is to get vaccinated. These warnings no longer mention masking, or any of the other Swiss-cheese layers of mitigation that were prevalent in the early days of this ongoing pandemic.
The problem with the prevailing, vaccine centered strategy is that if you are a parent with children under five, barriers to access are real. In many cases, meaningful tools and changes that would address these obstacles are lacking, such as offering vaccines at more locations, mandating masks at these sites, and providing paid leave time to get the shots.
Children are at risk
Data presented at the most recent FDA advisory panel on COVID-19 vaccines showed that in the last year infants under six months had the third highest rate of hospitalization. “From the beginning, the message has been that kids don’t get COVID, and then the message was, well kids get COVID, but it’s not serious,” says Elias Kass, a pediatrician in Seattle. “Then they waited so long on the initial vaccines that by the time kids could get vaccinated, the majority of them had been infected.”
A closer look at the data from the CDC also reveals that from January 2022 to January 2023 children aged 6 to 23 months were more likely to be hospitalized than all other vaccine eligible pediatric age groups.
“We sort of forced an entire generation of kids to be infected with a novel virus and just don't give a shit, like nobody cares about kids,” Kass says. In some cases, COVID has wreaked havoc with the immune systems of very young children at his practice, making them vulnerable to other illnesses, he said. “And now we have kids that have had COVID two or three times, and we don’t know what is going to happen to them.”
Jumping through hurdles
Children under five were the last group to have an emergency use authorization (EUA) granted for the COVID-19 vaccine, a year and a half after adult vaccine approval. In June 2022, 30,000 sites were initially available for children across the country. Six months later, when boosters became available, there were only 5,000.
Currently, only 3.8% of children under two have completed a primary series, according to the CDC. An even more abysmal 0.2% under two have gotten a booster.
Ariadne Labs, a health center affiliated with Harvard, is trying to understand why these gaps exist. In conjunction with Boston Children’s Hospital, they have created a vaccine equity planner that maps the locations of vaccine deserts based on factors such as social vulnerability indexes and transportation access.
“People are having to travel farther because the sites are just few and far between,” says Benjy Renton, a research assistant at Ariadne.
Michelle Baltes-Breitwisch, a pharmacist, and her two-year-old daughter, Charlee, live in Iowa. When the boosters first came out she expected her toddler could get it close to home, but her husband had to drive Charlee four hours roundtrip.
This experience hasn’t been uncommon, especially in rural parts of the U.S. If parents wanted vaccines for their young children shortly after approval, they faced the prospect of loading babies and toddlers, famous for their calm demeanor, into cars for lengthy rides. The situation continues today. Mrs. Smith*, a grant writer and non-profit advisor who lives in Idaho, is still unable to get her child the bivalent booster because a two-hour one-way drive in winter weather isn’t possible.
It can be more difficult for low wage earners to take time off, which poses challenges especially in a number of rural counties across the country, where weekend hours for getting the shots may be limited.
Protect Their Future (PTF), a grassroots organization focusing on advocacy for the health care of children, hears from parents several times a week who are having trouble finding vaccines. The vaccine rollout “has been a total mess,” says Tamara Lea Spira, co-founder of PTF “It’s been very hard for people to access vaccines for children, particularly those under three.”
Seventeen states have passed laws that give pharmacists authority to vaccinate as young as six months. Under federal law, the minimum age in other states is three. Even in the states that allow vaccination of toddlers, each pharmacy chain varies. Some require prescriptions.
It takes time to make phone calls to confirm availability and book appointments online. “So it means that the parents who are getting their children vaccinated are those who are even more motivated and with the time and the resources to understand whether and how their kids can get vaccinated,” says Tiffany Green, an associate professor in population health sciences at the University of Wisconsin at Madison.
Green adds, “And then we have the contraction of vaccine availability in terms of sites…who is most likely to be affected? It's the usual suspects, children of color, disabled children, low-income children.”
It can be more difficult for low wage earners to take time off, which poses challenges especially in a number of rural counties across the country, where weekend hours for getting the shots may be limited. In Bibb County, Ala., vaccinations take place only on Wednesdays from 1:45 to 3:00 pm.
“People who are focused on putting food on the table or stressed about having enough money to pay rent aren't going to prioritize getting vaccinated that day,” says Julia Raifman, assistant professor of health law, policy and management at Boston University. She created the COVID-19 U.S. State Policy Database, which tracks state health and economic policies related to the pandemic.
Most states in the U.S. lack paid sick leave policies, and the average paid sick days with private employers is about one week. Green says, “I think COVID should have been a wake-up call that this is necessary.”
Maskless waiting rooms
For her son, Holmes spent hours making phone calls but could uncover no clear answers. No one could estimate an arrival date for the booster. “It disappoints me greatly that the process for locating COVID-19 vaccinations for young children requires so much legwork in terms of time and resources,” she says.
In January, she found a pharmacy 30 minutes away that could vaccinate Theo. With her son being too young to mask, she waited in the car with him as long as possible to avoid a busy, maskless waiting room.
Kids under two, such as Theo, are advised not to wear masks, which make it too hard for them to breathe. With masking policies a rarity these days, waiting rooms for vaccines present another barrier to access. Even in healthcare settings, current CDC guidance only requires masking during high transmission or when treating COVID positive patients directly.
“This is a group that is really left behind,” says Raifman. “They cannot wear masks themselves. They really depend on others around them wearing masks. There's not even one train car they can go on if their parents need to take public transportation… and not risk COVID transmission.”
Yet another challenge is presented for those who don’t speak English or Spanish. According to Translators without Borders, 65 million people in America speak a language other than English. Most state departments of health have a COVID-19 web page that redirects to the federal vaccines.gov in English, with an option to translate to Spanish only.
The main avenue for accessing information on vaccines relies on an internet connection, but 22 percent of rural Americans lack broadband access. “People who lack digital access, or don’t speak English…or know how to navigate or work with computers are unable to use that service and then don’t have access to the vaccines because they just don’t know how to get to them,” Jirmanus, an affiliate of the FXB Center for Health and Human Rights at Harvard and a member of The People’s CDC explains. She sees this issue frequently when working with immigrant communities in Massachusetts. “You really have to meet people where they’re at, and that means physically where they’re at.”
Equitable solutions
Grassroots and advocacy organizations like PTF have been filling a lot of the holes left by spotty federal policy. “In many ways this collective care has been as important as our gains to access the vaccine itself,” says Spira, the PTF co-founder.
PTF facilitates peer-to-peer networks of parents that offer support to each other. At least one parent in the group has crowdsourced information on locations that are providing vaccines for the very young and created a spreadsheet displaying vaccine locations. “It is incredible to me still that this vacuum of information and support exists, and it took a totally grassroots and volunteer effort of parents and physicians to try and respond to this need.” says Spira.
Kass, who is also affiliated with PTF, has been vaccinating any child who comes to his independent practice, regardless of whether they’re one of his patients or have insurance. “I think putting everything on retail pharmacies is not appropriate. By the time the kids' vaccines were released, all of our mass vaccination sites had been taken down.” A big way to help parents and pediatricians would be to allow mixing and matching. Any child who has had the full Pfizer series has had to forgo a bivalent booster.
“I think getting those first two or three doses into kids should still be a priority, and I don’t want to lose sight of all that,” states Renton, the researcher at Ariadne Labs. Through the vaccine equity planner, he has been trying to see if there are places where mobile clinics can go to improve access. Renton continues to work with local and state planners to aid in vaccine planning. “I think any way we can make that process a lot easier…will go a long way into building vaccine confidence and getting people vaccinated,” Renton says.

Other changes need to come from the CDC. Even though the CDC “has this historic reputation and a mission of valuing equity and promoting health,” Jirmanus says, “they’re really failing. The emphasis on personal responsibility is leaving a lot of people behind.” She believes another avenue for more equitable access is creating legislation for upgraded ventilation in indoor public spaces.
Given the gaps in state policies, federal leadership matters, Raifman says. With the FDA leaning toward a yearly COVID vaccine, an equity lens from the CDC will be even more critical. “We can have data driven approaches to using evidence based policies like mask policies, when and where they're most important,” she says. Raifman wants to see a sustainable system of vaccine delivery across the country complemented with a surge preparedness plan.
With the public health emergency ending and vaccines going to the private market sometime in 2023, it seems unlikely that vaccine access is going to improve. Now more than ever, ”We need to be able to extend to people the choice of not being infected with COVID,” Jirmanus says.

The larvae of adult black soldier flies can turn food waste into sustainable protein with minimal methane gas emissions.
Their capacity to consume presents a neat response to the problem of food waste, which contributes up to 8% of global greenhouse gas emissions each year as it rots in landfill.
"The maggots eat the food fairly fresh," Gordon says. "So, there's minimal degradation and you don't get those methane emissions."
Alongside their ability to devour waste, the soldier fly larvae hold further agricultural promise: they yield an incredibly efficient protein. After the maggots have binged for about 12 days, Goterra harvests and processes them into a protein-rich livestock feed. Their excrement, known as frass, is also collected and turned into soil conditioner.
"We are producing protein in a basement," says Gordon. "It's urban farming – really sustainable, urban farming."

Goterra's founder Olympia Yarger started producing the insects in "buckets in her backyard" in 2016. Today, Goterra has a large-scale processing plant and has developed proprietary modules – in shipping containers – that use robotics to manage the larvae.
The modules have been installed on site at municipal buildings, hospitals, supermarkets, several McDonald's restaurants, and a range of smaller enterprises in Australia. Users pay a subscription fee and simply pour in the waste; Goterra visits once a fortnight to harvest the bugs.
Insect agriculture is well established outside of the West, and the practice is gaining traction around the world. China has mega-facilities that can process hundreds of tons of waste in a day. In Kenya, a program recently trained 2000 farmers in soldier fly farming to boost their economic security. French biotech company InnovaFeed, in partnership with US agricultural heavyweight ADM, plans to build "the world's largest insect protein facility" in Illinois this year.
"The [maggots] are science fiction on earth. Watching them work is awe-inspiring."
But the concept is still not to everyone's taste.
"This is still a topic that I say is a bit like black liquorice – people tend to either really like it or really don't," says Wendy Lu McGill, Communications Director at the North American Coalition of Insect Agriculture (NACIA).
Formed in 2016, NACIA now has over 100 members – including researchers and commercial producers of black soldier flies, meal worms and crickets.
McGill says there have been a few iterations of insect agriculture in the US – beginning with worms produced for bait after World War II then shifting to food for exotic pets. The current focus – "insects as food and feed" – took root about a decade ago, with the establishment of the first commercial farms for this purpose.
"We're starting to see more expansion in the U.S. and a lot of the larger investments have been for black soldier fly producers," McGill says. "They tend to have larger facilities and the animal feed market they're looking at is potentially quite large."
InnovaFeed's Illinois facility is set to produce 60,000 metric tons of animal feed protein per year.
"They'll be trying to employ many different circular principles," McGill says of the project. "For example, the heat from the feed factory – the excess heat that would normally just be vented – will be used to heat the other side that's raising the black soldier fly."
Although commercial applications have started to flourish recently, scientific knowledge of the black soldier fly's potential has existed for decades.
Dr. Jeffery Tomberlin, an entomologist at Texas A&M University, has been studying the insect for over 20 years, contributing to key technologies used in the industry. He also founded Evo, a black soldier fly company in Texas, which feeds its larvae the waste from a local bakery and distillery.
"They are science fiction on earth," he says of the maggots. "Watching them work is awe-inspiring."
Tomberlin says fly farms can work effectively at different scales, and present possibilities for non-Western countries to shift towards "commodity independence."
"You don't have to have millions of dollars invested to be successful in producing this insect," he says. "[A farm] can be as simple as an open barn along the equator to a 30,000 square-foot indoor facility in the Netherlands."
As the world's population balloons, food insecurity is an increasing concern. By 2050, the UN predicts that to feed our projected population we will need to ramp up food production by at least 60%. Insect agriculture, which uses very little land and water compared to traditional livestock farming, could play a key role.
Insects may become more common human food, but the current commercial focus is animal feed. Aquaculture is a key market, with insects presenting an alternative to fish meal derived from over-exploited stocks. Insect meal is also increasingly popular in pet food, particularly in Europe.
While recent investment has been strong – NACIA says 2020 was the best year yet – reaching a scale that can match existing agricultural industries and providing a competitive price point are still hurdles for insect agriculture.
But COVID-19 has strengthened the argument for new agricultural approaches, such as the decentralized, indoor systems and circular principles employed by insect farms.
"This has given the world a preview – which no one wanted – of [future] supply chain disruptions," says McGill.
As the industry works to meet demand, Tomberlin predicts diversification and product innovation: "I think food science is going to play a big part in that. They can take an insect and create ice cream." (Dried soldier fly larvae "taste kind of like popcorn," if you were wondering.)
Tomberlin says the insects could even become an interplanetary protein source: "I do believe in that. I mean, if we're going to colonize other planets, we need to be sustainable."
But he issues a word of caution about the industry growing too big, too fast: "I think we as an industry need to be very careful of how we harness and apply [our knowledge]. The black soldier fly is considered the crown jewel today, but if it's mismanaged, it can be relegated back to a past."
Goterra's Gordon also warns against rushing into mass production: "If you're just replacing big intensive animal agriculture with big intensive animal agriculture with more efficient animals, then what's the change you're really effecting?"
But he expects the industry will continue its rise though the next decade, and Goterra – fuelled by recent $8 million Series A funding – plans to expand internationally this year.
"Within 10 years' time, I would like to see the vast majority of our unavoidable food waste being used to produce maggots to go into a protein application," Gordon says.
"There's no lack of demand. And there's no lack of food waste."
