Against COVID‐19 vaccination of healthy children

Abstract COVID‐19 vaccination of children has begun in a number of countries with provisional regulatory approval and public support. This article provides an ethical analysis of COVID‐19 vaccination of healthy children. Specifically, we present three of the strongest arguments that might justify COVID‐19 vaccination of children: (a) an argument from paternalism, (b) an argument from indirect protection and altruism, and (c) an argument from global eradication. We offer a series of objections to each of these arguments to show that none of them is currently tenable. Given the minimal direct benefit of COVID‐19 vaccination for healthy children, the potential for rare risks to outweigh these benefits and to undermine vaccine confidence, the substantial evidence that COVID‐19 vaccination confers adequate protection to risk groups whether or not healthy children are vaccinated and that current vaccines do not provide sterilizing immunity, and given that eradication of the virus is neither feasible nor a high priority for global health, we argue that routine COVID‐19 vaccination of healthy children is currently ethically unjustified. Since mandates for children have already been implemented in some places (e.g., California) and may be considered elsewhere, we also present two additional arguments explicitly against making COVID‐19 vaccination mandatory for children.

This article presents an analysis of the ethics of vaccinating healthy children against COVID-19 by responding to the strongest arguments that might favor such an approach. 5 In particular, we present three arguments that might justify routine 6 COVID-19 vaccination of children, based on (a) an argument from paternalism, (b) an argument from indirect protection and altruism, and (c) an argument from the global public health aim of COVID-19 eradication. 7 We offer a series of objections to each respective argument to show that, given the best available data, none of them is tenable. These arguments, which might be compelling for childhood vaccination against other diseases and in different circumstances, 8  If one accepts our conclusion that routine vaccination of healthy children against COVID-19 is ethically unjustified, then it follows that coercion, which is an ethically problematic issue in itself, is even less warranted. Nonetheless, mandatory vaccination of healthy children against COVID-19 is already being considered-and, in some places, implemented-as a way of increasing vaccine uptake. 9 We therefore also provide two objections specifically against making COVID-19 vaccination mandatory for children, which center on additional ethical concerns about overriding the autonomy of parents and legal guardians and of children who are capable of making autonomous decisions. If vaccinating healthy children against COVID-19 is ethically problematic, then coercing vaccination is even less acceptable-but even if vaccinating healthy children against COVID-19 should at some future point be considered more defensible (e.g., should a much more favorable cost-benefit analysis emerge), important ethical objections against coercive mandates will still remain.

| ARGUMENT FROM PATERNALISM
The first argument in favor of childhood vaccination for COVID-19 derives from paternalistic considerations and holds that routine vaccination of healthy children is justified because it is in the best interests of the would-be vaccinated children. The argument from paternalism suggests that COVID-19 vaccination will, all things considered, benefit children the most (or cause them the least harm). Given that routine vaccination is the most effective way to ensure vaccine uptake, it is therefore justified for the sake of the health and well-being of children themselves.

| Objection 1: Low risk of COVID-19 morbidity and mortality to children
According to the best available data, healthy children are at a much lower risk of severe illness from COVID-19 and are less susceptible to infection than older adults. 10 In contrast to many other vaccine-preventable diseases, healthy children are at low risk of severe COVID-19 infection, morbidity, and mortality. 11 Hospitalization of children with COVID-19 is rare, although emerging data suggest that children with severe underlying comorbidities are at higher risk. 12 Deaths among healthy children due to COVID-19 are very rare; for example, a large study in Germany found no deaths among children aged 5-11 without comorbidities. 13  (2020). Is there a role for childhood vaccination against COVID-19? Pediatric Allergy and Immunology, 32, 9-16. 5 We focus our analysis on healthy children because, as will be discussed later in the article, there may be more compelling reasons to vaccinate at least some vulnerable children against . Throughout the article, where we refer simply to children, this should be taken to imply healthy children. 6 By "routine" vaccination we mean vaccination that is recommended for everyone, so that routine vaccination of children should be understood as the general recommendation that all children get vaccinated against COVID-19, whether or not the rationale for the recommendation is emergency use. In the United States, for example, given the emergency use authorization of the Pfizer-BioNTech COVID-19 vaccine in children aged 5-11, routine vaccination for this age group means offering the vaccine to all eligible children (whether it is simply offered, actively encouraged, required, or even mandated). 7 We consider these three arguments to be the most ethically relevant and potentially convincing for vaccinating children against COVID-19. However, should additional arguments for vaccinating children be raised, then these would have to be critically appraised together with the three arguments presented in this paper for an all-things-considered judgment. In other words, those who would argue in favor of vaccinating children against COVID-19 would have to show that the objections against the three arguments in this paper do not hold, or that some additional argument(s) are of greater ethical significance than the arguments considered here. Thanks to an anonymous reviewer for pressing us to clarify this point.  15 Overall, the burden of COVID-19 in children appears to be similar to or lower than that of typical seasonal influenza in the winter (unlike the much higher disease burden of COVID-19 in adults). 16  groups together people of all ages up to and including 49," with this group making up only 0.7% of the total number of people who died from COVID-19 to date. It must also be noted that none of these data specify relevant comorbidities, yet most children who become severely ill or die from COVID-19 have one or more underlying medical conditions. 22 For infection with the Omicron variant, the severity of disease outcome was found to be significantly lower for all ages, including pediatric age groups, compared to Delta. 23 Furthermore, post-infection immunity has been found to be at least as effective as vaccination at protecting against disease due to reinfection with COVID-19. 24 An increasingly large body of evidence suggests that immunity after previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is at least as robust as vaccine-induced immunity. 25 Childhood exposure to SARS-CoV-2, which, as previously discussed, is generally associated with mild viral illness, may offer protection against more severe illness in adulthood. 26   It has sometimes been maintained that children often suffer significant post-acute symptoms (also known as "long covid") even after mild or asymptomatic infection. 28 The preliminary data for studies supporting such an association have lacked control groups and therefore must be interpreted with caution. 29 The idea that healthy children suffer significant post-acute symptoms after mild or asymptomatic infection is not supported by more careful analysis of current evidence. 30 A largescale recent estimate in the UK found that rates of symptoms 12-16 weeks after COVID-19 infection in children were not statistically different from rates of symptoms among controls. 31 Relatedly, it is biologically implausible that an infection that is usually mild or asymptomatic in children would commonly result in severe postinfection symptoms; post-COVID-19 fatigue in adults was found to be strongly correlated with the severity of illness. 32 Therefore, at this point, protecting healthy children against "long covid" does not in itself provide a strong argument for routinely vaccinating all healthy children. Should adequately controlled future data show that "long covid" more substantially affects healthy children, then this would add more weight to the argument that COVID-19 vaccination is justified for the sake of healthy children themselves. 33 As COVID-19 may pose more serious risks in some children (e.g., children with obesity or severe comorbidities), vaccinating those children may be better justified by appeals to their own interests. 34 It should be noted, however, that not all "vulnerable" groups are necessarily at increased risk of severe illness from COVID-19. A recent study, for instance, found that immunocompromised children and young people in the UK were at no increased risks of severe COVID-19. 35 In any case, in light of present knowledge, it is much more difficult to justify vaccination of all children for their own sake, given the relatively low vaccine-generated benefits and mild average disease severity. 36 These low expected benefits need, moreover, to be balanced against potential risks, which will be addressed in the following section.
2.2 | Objection 2: Known risks and unknown long-term vaccine safety profile for children The case for vaccinating healthy children against COVID-19 for their own sake is undermined by uncertainty; that is, by the currently poorly characterized potential for rare, harmful outcomes associated with the vaccines in children. Public safety data from the Pfizer-BioNTech clinical trials in children included 2,260 participants aged 12 to 15, of which 1,131 received the vaccine. 37 In addition to a small sample size, the trial follow up period was of short duration; therefore, no reliable data presently exist for rare or longer-term vaccine-related harms. 38 Though common adverse events occurring less than 6 months after vaccination may be ruled out, the risks of rare or delayed adverse outcomes can simply not yet be evaluated. 39 Should vaccine harms occur, they will be revealed in the general pediatric population only after thousands or millions of children are already vaccinated, which would also risk seriously undermining vaccine confidence. The restriction of AstraZeneca vaccines to older age groups due to blood clotting events early on in the COVID-19 vaccination rollout, as well as reports of increased rates of vaccine-related myocarditis among younger age groups illustrates that rare risks are sometimes more common in younger age groups and might sometimes outweigh benefits in children. 40  Reduced maximal aerobic capacity after COVID-19 in young adult recruits, Switzerland, May 2020. Eurosurveillance, 25(36), 1-4. 33 Given that there are both risks and uncertainties related to COVID-19 vaccines for children, this gives us reason to be cautious. On the other hand, uncertainty about long-term effects of COVID-19 on children may provide a reason to consider vaccination after all.
However, given that the effects of long covid appear to be minimal, and given the already known rare but potentially severe harms of the vaccines, the balance of ethical considerations appears to be against routine vaccination of healthy children. Thanks to an anonymous reviewer for pressing us on this point. 34 It might turn out that tailored vaccination against COVID-19 for vulnerable children will be more expensive to implement than universal vaccination. A cost-benefit analysis of this kind is important to consider when it comes to the ethics of COVID-19 vaccination of children. At present, however, potential implementation costs provide relatively little weight against a tailored approach given that several risk factors (such as obesity) are now well described, and provided that (under a tailored approach) vaccines remain easily accessible for parents who wish to access them for their children. Thanks to an anonymous reviewer for raising this point.  36 We do not wish to give the impression that we reject paternalistic reasons for routine childhood vaccination altogether. Paternalism-the best interests of children-is probably the single most important justification for childhood vaccination. Even for rare diseases (e.g., polio), routine vaccination may be justified on the grounds that, while the disease is rare, the protection provided by herd immunity is in the best interest of children as a group, given the severity of the disease for children should they become infected (i.e., should herd immunity wane). As we have argued, however, these conditions do not hold for COVID-19 in the case of children. Thanks to an anonymous reviewer for pressing us to clarify this point. ted in adolescents as well as in adults. 42 The risk of vaccine-caused myocarditis appears to be higher in younger age groups-especially males-compared to older groups. 43 Sweden and Denmark, for instance, recently announced that they are halting use of Moderna's COVID-19 vaccine for younger age groups after reports of rare cardiovascular side-effects. 44 Sweden, in fact, has decided against recommending COVID-19 vaccines for children aged 5-11 altogether. 45 France and Germany have also announced that they will no longer offer the Moderna vaccine to people under the age of 30 due to elevated risks of heart inflammation. 46 The U.K. Joint Committee on Vaccination and Immunization (JCVI) has moreover recommended against vaccinating healthy children (i.e., children who do not have underlying health conditions that increase their risk from severe COVID-19). Upon reviewing the evidence for vaccination in children aged 12-15, the JCVI concluded that for this population, "the health benefits from vaccination are marginally greater than the potential known harms." 47 The JCVI recommendation concerns children aged 12-15. For children aged 5-11 (the group for whom the U.S. FDA has recently authorized emergency use), the balance for vaccination is presumably less favorable, given that COVID-19 morbidity and mortality rates decrease with younger age groups. 48 The difference of opinion among experts and regulators suggests, at a minimum, that it is currently uncertain whether the benefits of mRNA vaccines for children outweigh the risks. 49 Although COVID-19 might pose more serious risks for children with severe underlying comorbidities, so that some potential vaccine risks may be more justified by potential benefits in such groups, there is reason to think that a uniform approach for all such children may be problematic. Vaccines have been recalled in the past after adverse effects in children were identified when the vaccine was already in routine use. 52 In some cases, the adverse effects occurred many months after vaccine administration. 53 The lack of long-term safety data therefore warrants caution about vaccinating children against COVID-19.
Given that the combination of known vaccine risks and uncertainties available, this assessment might change. However, because of the low expected benefits for healthy children rooted in the best available evidence, justifying COVID-19 vaccination by appealing to children's own interests will most likely remain ethically questionable.
In sum, vaccination of healthy children against COVID-19 cannot presently be defended on paternalistic grounds.

| ARGUMENT FROM INDIRECT PROTECTION AND ALTRUISM
The second argument is grounded in the potential benefits that vaccinating healthy children against COVID-19 can provide to others.
According to this argument, routine vaccination of children against COVID-19 is ethically justified because healthy children should get vaccinated in order to protect vulnerable groups.

| Objection 3: Children are not a major driver of transmission
Children are both substantially less susceptible to  infection and, if infected, are significantly less likely than adults to infect others. 54 Most secondary infections directly attributable to children tend to occur within households. 55 Yet the secondary attack rate for children to household members is low compared to adults. 56 Since high community transmission in adults is the main driver of COVID-19 epidemics-and infection of children-as well as disease burden, the public health benefits of vaccinating children in terms of transmission reduction (even if current vaccines were to provide sterilizing immunity, which, as we will discuss, they do not) are likely to be small and may be negligible where a high proportion of adults are already vaccinated. 57 Moreover, if vaccination of adults and vulnerable children is maintained at a high level, as discussed in the next objection, then the public health consequences of the spread of the virus among healthy children and from them to others will be limited.

| Objection 4: Vulnerable groups can protect themselves and current vaccines do not provide sterilizing immunity
Some vaccines (e.g., influenza) are much less effective in certain vulnerable groups (e.g., the elderly). When, in addition, nonvulnerable groups are significant spreaders of a virus (e.g., children in the case of influenza), there may be a strong prima facie case for vaccinating the non-vulnerable group-even if that group does not stand to benefit as much from the vaccine as the vulnerable group, for whose sake vaccine policy could in part be ethically justified. 58 On neither count, however, does this reasoning seem to hold for COVID-19.
For COVID-19, vaccines are safe and effective in higher-risk groups, including older adults and the immunocompromised, 59 and significantly reduce the risk of severe illness even when vaccinated groups are exposed to substantial community transmission. 60 While there are some people for whom the current COVID-19 vaccines are contraindicated (e.g., those with severe allergies), this group appears to be small. 61 It is therefore not the case that vulnerable groups cannot protect themselves, which would make routine vaccination of less vulnerable groups-children, in this case-more compelling.
Moreover, as argued above, children are not major drivers of COVID-19 transmission. As such, there is no strong ethical justification for COVID-19 vaccination of healthy children for the sake of vulnerable groups.
It has been argued that people have a moral obligation to contribute to population or "herd" immunity by getting vaccinated. 62 However, in the case of COVID-19, it now appears unlikely that elimination via herd immunity is a possibility. 63 Furthermore, as previously discussed, COVID-19 vaccination is 54 Monod, M., Blenkinsop, A., Xi, X., Hebert, D., Bershan, S., Tietze, S., Baguelin, M., Bradley, highly effective in vulnerable groups. The case for routinely vaccinating children in order that they might contribute to herd immunity is therefore weak, especially since it has become clear that the current COVID-19 vaccines do not provide sterilizing immunity. 64  There are also other reasons to think that the indirect protection argument is less apt in the case of COVID-19. Unlike in the case of vaccines for some other pathogens, very few people in risk groups will be unable to get vaccinated, provided that access is unconstrained. First, because most COVID-19 vaccines are not live vaccines (meaning that they are safe for immunocompromised people); and, second, because there are multiple different vaccine platforms, meaning that in rare cases where someone has an allergy to a product in one particular vaccine, they may be offered an alternative one.
Even if COVID-19 vaccines are highly effective (say 95%-99%) against severe disease, there might be a small group (say 1%-5%) in whom protection is weaker and who may therefore be better off if everyone were vaccinated. Nevertheless, since vaccination of the majority of adults will already significantly reduce the probability that those less protected by vaccination will be infected in the first place, this reasoning is hardly sufficient to justify routine COVID-19 vaccination for all children at this point-at least not until there is a vaccine for this population with a well-confirmed, very high safety profile.
That few people will in principle be unable to get vaccinated does not imply, of course, that everyone who is eligible will get vaccinated.
That may be unwarranted optimism; vaccine uptake among adults mostly likely will not reach high levels in some places. 68 Nevertheless, if it should be the case that vaccine uptake is not sufficiently high in adult populations, the burden appears to rest on adult populations, rather than on children. 69

| Objection 5: A questionable case for altruism
While children with at least some degree of decisional autonomy (e.g., teenagers) may have an obligation to take precautions against infecting others in certain cases, 70 this obligation is significantly weakened when others are able to effectively protect themselves and when vaccines do not provide sterilizing immunity. As we have argued above, this is the case for Parents may have good reasons to vaccinate their child against an infectious disease even if they do not consider the risk of this disease to be substantial for their own child; for example, because their child frequently interacts with another child who is more vulnerable to the disease and cannot get vaccinated.
From a public health ethics perspective, treating children as a mere means to serve other people's or collective interests, if it can be justified, at the very least requires sufficiently large benefits to others and sufficiently small costs to children, which does not seem to be the case for COVID-19 vaccination. 76 Given the upshot of the discussion so far, including that vulnerable children and adults can be adequately protected by getting vaccinated and that people can still spread infection post-vaccination, the case of COVID-19 does not appear to raise sufficiently compelling reasons for parents to vaccinate their children solely or even primarily for the sake of others.
It must also be noted that healthy children who face very low risks from the virus have already been disproportionately harmed by non-pharmaceutical interventions against COVID-19, like school closures and lockdowns, all of which were primarily for the benefit of older and more vulnerable people. 77 A great deal has been demanded of and given by these children-ought we really to ask for more?
All in all, COVID-19 vaccination of healthy children is not justified on the grounds that healthy children should get vaccinated against COVID-19 in order to protect others.

| ARGUMENT FROM GLOBAL ERADICATION
The third argument is grounded in a pandemic "endgame" This argument might rely on at least three claims regarding unbridled transmission of the virus, namely that ongoing transmission will: (a) lead to the evolution of viral variants that are more harmful, perhaps also for children; (b) make the virus more likely to evolve to evade vaccine-derived immunity; and/or (c) ceteris paribus make the long-term cost-effectiveness of eradication more favorable than control. We provide objections to each of these claims in turn. 4.1 | Objection 6: Evidence against the evolution of more harmful variants Evolutionary fitness is primarily determined by transmissibility rather than virulence (i.e., propensity to cause harm), although these two terms are often confused or conflated. 80 Insofar as viruses readily infect human hosts, there is an evolutionary cost to causing (fatal) harm, even if this does not exclude the possibility of viral variants becoming somewhat more harmful than their predecessors. 81 Should variants evolve to be more harmful particularly for children, then the argument from paternalism might be strengthened (i.e., to the extent that children stand to benefit more from vaccination). However, this scenario is in our view improbable. Several seasonal coronaviruses (which also have variants) have continued to cause predominantly mild "common cold" illness in healthy children despite persistence as seasonal globally endemic viruses for decades or centuries; 82 even SARS, caused by a far more virulent coronavirus than COVID-19, is not particularly harmful to children. 83 Furthermore, the virulence of SARS was one factor that made this disease relatively easy to control and eliminate (i.e., because those infected were readily identifiable) 100,000 children every year for want of vaccine access-many more children than have died from COVID-19 to date. 89 Furthermore, the measles virus has so far demonstrated limited clinically significant immune escape in the face of vaccination, 90 while it is widely held that measles is a candidate for an eradicable vaccine preventable disease. 91 These conditions are not met, or remain uncertain, for COVID-19. Even if they were met, global health policy should, insomuch as it is directly concerned with the health of children, prioritize measles eradication and many other health goals before considering universal childhood vaccination for COVID-19.
Since low-income countries have little incentive to participate in a COVID-19 eradication campaign by universal vaccination while many other critical health needs of children are unmet, SARS-CoV-2 will inevitably become a globally endemic virus. 92 Yet this is likely to produce very little morbidity or mortality insofar as the majority of adults and are fully vaccinated. Over time, the age at first infection will continue to fall for COVID -19, such that, as for other coronaviruses, people will be universally infected in the early years of life and experience mild re-infections every few years. 93 While it is possible that vulnerable older adults will continue to face significant disease burden, as they do for other coronaviruses despite prior infection, 94 this burden can be controlled with an appropriate use and extension of existing vaccines. If we wish to minimize harms from COVID-19, it would be better to vaccinate vulnerable older adult populations around the world in low-and middleincome countries, who stand to benefit much more from getting vaccinated and for whom access is still scarce, than children in high-income countries. 95 Eradication of COVID-19 is therefore currently neither a feasible nor an ethically justifiable goal; its likely low long-term global disease burden, once most adults are vaccinated, will soon be insufficient for prioritization above other, more pressing, global health problems.
Thus, given the objections, routine vaccination of children is not justified on the grounds that it is required to globally eradicate COVID-19.

| OBJECTIONS AGAINST MANDATES
While the ethics of vaccinating healthy children against COVID-19 is still being debated around the world, mandatory vaccination of healthy children for COVID-19 has already been implemented in some places, like California and Costa Rica, and may be considered elsewhere. 96 The World Health Organization (WHO) defines a COVID-19 vaccine mandate as a way to "compel vaccination by direct or indirect threats of imposing restrictions in cases of non-compliance," which can be ethically justified under certain circumstances (e.g., to protect the health and well-being of the public), even if it interferes with individual freedom and autonomy. 97 Some have argued that selective mandates are ethically justifiable for specific populations, such as paternalistic mandates for those who are at highest risk of severe illness from COVID- 19. 98 However, if our ethical objections to routine vaccination of healthy children against COVID-19 are convincing-if one accepts that routine vaccination is at least presently unjustified-then it must follow that coercion, to the extent that this would require still further ethical justification, is also unwarranted. Even among populations for which there may be more pressing reasons to increase vaccine uptake than for children, like healthcare workers, mandatory vaccination already involves serious ethical issues and may cause collateral harms. 99 Nevertheless, given that the discussion about mandates is already underway and is likely to persist, we present two additional objections specifically against mandating vaccination of healthy children against COVID-19, which might be considered in addition to any relevant ethical problems related to vaccine mandates in general.

| Objection 9: Limiting parental autonomy
Mandates for children to be vaccinated against COVID-19 would limit and, depending on their nature, even override the autonomy of parents and guardians to make decisions about the health of their children. This requires ethical justification as such, but it demands stronger justification in proportion to the level of coercion that mandates would involve. 100 When mandates are in place, the actors who make decisions for the health and wellbeing of children de facto become governments and public health officials rather than parents, although less coercive measures (e.g., small fines) might allow some parents to opt out and thereby retain decisional autonomy. 101 To justify mandates that would limit or override parental autonomy, there needs to be at least some indication that parents and guardians might not be adequately discharging their duties to If one accepts our conclusions that vaccinating healthy children against COVID-19 is not required in order to protect others and not necessary for the public health goal of eradicating COVID-19, then it follows that other-regarding and public health considerations also do not justify making COVID-19 vaccination mandatory for children.

| Objection 10: Mandates preclude altruism for autonomous children
As previously discussed, perhaps some healthy children (e.g., teenagers) can autonomously make the altruistic choice to get vaccinated for others. Clearly, overriding the autonomy of these children through coercive measures will be as ethically problematic as for parents and legal guardians. However, there is an additional element to consider.
Encouraging children with decisional autonomy to get vaccinated for the sake of others may be a good thing, insofar as the vaccines are safe for them in the long term and insofar as children are able to adequately understand the associated risks and benefits. 104 Yet altruism crucially requires freedom; it depends on the proper kind of self-chosen motive to act for the sake of someone else. 105 Thus, even if some healthy children might choose to get vaccinated for the sake of others, mandates would preclude the possibility of freely acting on laudable altruistic motives. This argument is important for any attempt to enforce civic duties (e.g., through payments or fines), because regulating and especially enforcing other-regarding behavior arguably undermines solidarity, trust, reciprocity, and other communal values. 106 The same argument also affects potential altruistic behavior in the case of coercive vaccination policies for adults. 107 For healthy children who can make their own decisions, mandating vaccination against COVID-19 would undercut the altruistic motives that these children might otherwise heed.

| CONCLUSION
We have presented three of the most compelling arguments that might justify routine vaccination of healthy children against COVID-19: an argument from paternalism or the best interests of children, an argument from indirect protection or the best interests of vulnerable others, and an argument from global eradication or the best interests of a global COVID-19 public health endgame. Through sustained objections to each respective argument, we have shown that, given the present evidence regarding the disease and the available vaccines, none is ultimately sufficient to justify routine COVID-19 vaccination of healthy children. We also elaborated two further objections specifically against mandating COVID-19 vaccination for children: one based on ethical issues surrounding coercion and parental autonomy, and the other based on the idea that mandates would undermine potentially altruistic decisions of autonomous children to get vaccinated for the sake of others. All things considered, neither routine nor mandatory vaccination of healthy children against COVID-19 is currently ethically justified. 100 Giubilini, A. (2019). The ethics of vaccination. Palgrave Macmillan. 101 It should be noted here that one ethical worry with mandates is that it may create an unfair situation where some parents and guardians may be able to "afford" (i.e., literally when mandates take the form of a fine) to disregard mandates and to retain decisional autonomy in disregarding COVID-19 vaccination for their children, while others (e.g., less affluent parents and guardians) are significantly less able and thus less free to opt out.
