I. Introduction
As the COVID-19 vaccine rollout continues apace and hope slowly returns that we are on our way back to some sort of “normalcy”, many critical public health policy questions remain unanswered. One body of initiatives aimed at resuming normal life and raising concerns are the various vaccination certificates. These certificates would enable people to travel and access services upon presentation of a certificate showing that its bearer has been vaccinated. In some cases, an alternative would be to present a certificate of recovery (proving that the person has acquired some immunity) or a test certificate (proving that they have received a negative test result), valid only for a short period.Footnote 1 Some countries, such as Israel – the world champion of vaccination – with its digital green pass,Footnote 2 New York City with its digital vaccine passFootnote 3 and Denmark through it “coronapas”,Footnote 4 have already implemented their own vaccine certificates. The European Union (EU) is currently discussing the “Digital Green Certificate” to facilitate free movement.Footnote 5
In this context, some authors have considered vaccine certificates as “immediate policies that offer reasonable leeway for balancing protection of public health with a return to prepandemic life” and that “current circumstances” demand.Footnote 6 It is difficult to agree with this stance. If vaccination programmes are to protect the whole population, including the poor, the system of vaccination certificates itself is exclusionary, because of its difficult access for the least socioeconomically privileged people who will not be able to return to pre-pandemic life (Section II). More specifically, I argue in this paper that the system of vaccination certificates is likely to put poor people in a perpetual state of lockdown (Section III), discriminating against them (Section IV) and casting some serious doubts about its proportionality (Section V). Indeed, if by definition such a certificate system is based on privileges conferring special rights to the bearers, these privileges will in fact mainly be granted to socioeconomically privileged people who are more likely to get vaccinated, are not “essential” workers likely to see the exercise of their job conditioned by such a certificate, have a stable legal status, are likely to encounter fewer difficulties in dealing with the administrative vagaries linked to the granting of such certificates, etc., as the experience of the “Green Pass” in Israel has already shown.Footnote 7
The present contribution will mainly deal with the consequences of such certificates for the socioeconomically underprivileged within developed countries, where vaccination has generally been much faster than in most developing countries and where the introduction of such certificates is on policy agendas where they have not already been implemented. I will focus more specifically on EU countries and will also borrow some examples from Israel, the USA and the UK. Although I do not deal with it in my paper, it is important to bear in mind that such certificates also have important consequences in terms of global inequalities as they add barriers to migration and travel, especially between the poorer and richer world regions, an issue that is addressed by Martina Tazzioli and Jouni Häkli in the present special issue.Footnote 8
II. Difficult access for the poor
Socioeconomically disadvantaged people are the most affected by the COVID-19 crisis due to their higher exposure to the virus, which is in turn driven by a variety of socioeconomic factors.Footnote 9 Several studies have shown the same phenomenon in the context of previous pandemics, such as the Spanish flu of 1918, which mainly affected the working class whether that was in India, Norway or the USA.Footnote 10 It was no different with the H1N1 flu of 2009.Footnote 11
First, socioeconomically disadvantaged people are among the “at-risk” groups because of their overrepresentation among people suffering from cardiovascular disease, diabetes, cancer and chronic disease.Footnote 12 Second, their living conditions make them more vulnerable to the virus.Footnote 13 Third, when they are employed, these people are more commonly exposed to the virus because of the nature of their work.Footnote 14 Fourth, they have greater difficulty accessing the health system.Footnote 15 Fifth, measures taken by public authorities in the context of lockdownFootnote 16 have de facto hit people who live in cramped, unsanitary, overcrowded housing without green spaces more severely, including people who find themselves in social and human distress.Footnote 17 Finally, workers who are undeclared or hired in the informal sectors – overrepresented among irregular migrants – have been left without income and social protection. In addition, poor people have also been targeted by the police in terms of sanctions for non-compliance with lockdownFootnote 18 and likely particularly to be affected by financial penalties for non-respect of lockdown.Footnote 19
Making a vaccination programme widely available constitutes an international obligation for public authorities, including under Article 12(2)c) of the International Covenant for Economic, Social and Cultural Rights, which enshrines the right to prevention, treatment and control of disease, including the implementation or enhancement of immunisation programmes and other infectious disease control strategies.Footnote 20 The European Committee for Social Rights has also recalled that “States Parties must operate widely accessible immunization programmes. They must maintain high coverage rates not only to reduce the incidence of these diseases, but also to neutralize the reservoir of the virus and thus achieve the goals set by WHO to eradicate several infectious diseases”.Footnote 21 More generally, the European Court of Human Rights (ECHR) has recently recognised that “vaccination is one of the most successful and cost-effective health interventions”Footnote 22 echoing the World Health Organization’s (WHO) position on COVID-19, according to which “vaccines are one of the most effective tools for protecting people against COVID-19”.Footnote 23
Against this background, if vaccines against COVID-19 appear as an urgent and important remedy to protect the socioeconomically underprivileged people more heavily affected than the rest of the population, the vaccination certificates are likely to exclude them. The ways such certificates work and the conditions they impose differ from one country, city or region to another, and many are still blurred and uncertain. However, before these certificates become a common practice all over the world, especially in developing countries, it is urgent to highlight the danger they present for the fundamental rights of the poor, who are less likely to gain access to and then benefit from such certificates. Indeed, poor people are among the sections of the population who are the least vaccinated,Footnote 24 not only because of practical and administrative obstacles,Footnote 25 but also because of their higher vaccination hesitancy and their mistrust in the health system, which is partly explained by their experience of long-standing discrimination, as poor people usually belong to minorities and discriminated groups.Footnote 26 This is, for instance, the case for the Roma community in Hungary,Footnote 27 but also black people in the UKFootnote 28 and the USA,Footnote 29 and the Bedouin community in the South of IsraelFootnote 30 in the context of COVID-19, confirming studies carried out previously according to which low-skilled and poor people tend to be less commonly vaccinated, although they are among the “at-risk” groups.Footnote 31 In addition, many Western countries do not include irregular migrants in their vaccination plans, making a whole group of people – already in the shadows – de facto outside of any health protection.Footnote 32 Finally, the digital divide is another obstacle likely to make it difficult for the poor to access certificates.Footnote 33 Although for the present these certificates appear to be being made available digitally and in paper, in the event that only the former type becomes the norm, poor people who do not have the necessary digital resources will not be able to use them.Footnote 34 Even if these certificates continue to be accessible on paper and digitally, other parts of the administrative process will normally be conducted online, which amounts to an additional obstacle. In other words, the lack of access to technology and digital skills is likely to perpetuate poverty, restricting social mobilityFootnote 35 and, in the case of vaccination certificates, physical mobility tout court. All of the abovementioned difficulties are likely to be persistent through time since repeated vaccinations may be required as the virus evolves, as explained by the WHO.Footnote 36
III. A perpetual state of lockdown for the poor
Most certificates are public in nature and cover cross-border travel, for which poor people are less likely to be affected, especially within the EU, where tertiary graduates are generally more mobile than the rest of the population.Footnote 37 However, low-skilled people (more likely to be socioeconomically underprivileged), especially from Eastern Europe, still move across borders.Footnote 38 Therefore, when they need to travel, these socioeconomically underprivileged people are likely to encounter more difficulties overcoming the barriers of the vaccination certificates, which derails their life or work projects for the reasons I explained in the previous section: either because they are not vaccinated and/or because they were unable to get a vaccination certificates for administrative reasons.
More importantly, beyond the question of cross-border travel, the vaccination certificate is also likely to be used by public and private actors for other purposes, either because the law says so or because of gaps in the regulation regarding these certificates, as is the case in Israel regarding labour law: because there is no regulation or collective agreement dealing with the case of unvaccinated workers, some employers took advantage of this vacuum to place entry restrictions for their unvaccinated workers or even terminating their employment contracts.Footnote 39 The fact that poor people are less likely to benefit from a certificate also carries with it the risk that they will be excluded from increasingly numerous services in society. Even more critically, if such certificates concern access to certain services – such as swimming pools, museums, restaurants, events, hairdressers, cinemas, etc. – in most countries that have so far implemented this type of certificate, it is reasonable to fear that over time such certificates will become more general: certificates are likely to be even more problematic if they are required to benefit from other services, such as nurseries, schools, social services, administrative services, supermarkets, etc., with a deterrent effect on the most marginalised populations. As a matter of fact, whether it is limited to certain services or generally, the vaccination certificate system in Western societies amounts to an indirect vaccination obligation, imposing on those who are not in possession of such a certificate a perpetual state of lockdown.
Furthermore, aside from the question of how the scope of the certificates will disadvantage the poor, the certificate system itself raises the important issue of the “non-take-up” phenomenon as regards the poor population. The “non-take-up” phenomenon describes a situation where people who have rights on paper do not claim them or benefit from them in practice. Even where many private and public services remain available to people who do not possess certificates, they will still constitute an additional invisible barrier that is likely to drive people not to claim the social benefits and rights they are entitled to, exacerbating the phenomenon of “non-take-up”. In 2004, there was between 40% and 80% of non-take-up in Organisation for Economic Co-operation and Development (OECD) countries, and recent studies have shown that this remains very high.Footnote 40 This issue of “non-take-up” has been confirmed in the context of the pandemic and the measures put in place by governments to help poor people because of complex procedures and bureaucratic jargon.Footnote 41 The causes of “non-take-up” are diverse, including a lack of information, transparency, institutional barriers, the complexity of the procedures and stigma.Footnote 42 The difficulty of “receiving” a certificate even once a person has been vaccinated should not be overlooked in light of the non-take-up issue. The administrative obstacles are real, especially for poor people, and this administrative requirement might be a new barrier for them, especially when these certificates expire after a period, as they do in Israel. In addition, it has been shown that stigma plays a role in this non-take-up phenomenon,Footnote 43 and that such stigma is likely to be intensified for people who do not have a vaccination certificate – even where it is not required as such – which is likely to exacerbate the situation of “non-take-up”.
IV. A discriminatory and stereotyping tool against the poor
Against this background, vaccination certificates are likely to discriminate against poor people, especially indirectly, since while they appear to be “neutral” measures applied to the entire population, their consequences are much worse for the poor because they are overrepresented among people who will not be in possession of such a certificate, not only as regards their mobility, but more importantly regarding the access to services and rights as explained in the previous section. Moreover, where criminal and administrative sanctions can be imposed for the failure to obtain or present a certificate, as in Denmark, the fact that the rich and the poor have to pay the same fine might be regarded as indirect discrimination since it is likely to affect poor people much more than the more privileged classes, especially where custodial sentences are available in the case of non-payment, as in Germany, Switzerland or the USA.Footnote 44
Furthermore, poor people who are particularly affected by these vaccination certificates are likely to fall into situations of intersectional or additive discriminationsFootnote 45 : poor families “with a migration background”,Footnote 46 single women and mothers overexposed to poverty and overrepresented in low-paid jobs,Footnote 47 Roma, people of colour, etc. In other words, people are likely to be discriminated against by the vaccination certificate system not only on the grounds of their socioeconomic underprivileged situation, but also on the basis of other characteristics such as ethnic origin, race or gender, which intersect or add up to their situation of precariousness. Indeed, on the one hand, “status-based discrimination is frequently closely correlated with socioeconomic disadvantage”Footnote 48 since “[g]roups which suffer from discrimination on status grounds [gender, race] … are disproportionately represented among people living in poverty”.Footnote 49 On the other hand, poor people themselves are subjected to stereotyping, prejudice, stigma and discrimination because of their precarious situations.Footnote 50 In this regard, poverty is not only a consequence but also a cause of discrimination, creating a vicious cycle. As a matter of fact, an intersectional or additive approach of discrimination that includes, among others, status grounds related to the socioeconomic situation is particularly important when assessing the legality of the measures justified by public health protection in the context of the pandemic – especially the vaccination certificates – because it is a way to recognise that “privilege and disadvantage migrate across identity categories”.Footnote 51
More importantly, vaccination certificates also raise the important issue of stereotyping and stigma against the poor. Many examples show that beyond the disadvantages that the poor and undereducated face, they are also victims of stereotyping and stigma, which can be defined as “beliefs about the characteristics of groups of people” that are predominantly negative.Footnote 52 Stereotypes “serve to maintain existing power relationships; they are control mechanisms. Stereotypes uphold a symbolic and real hierarchy between ‘us’ and ‘them’”.Footnote 53 As for the COVID-19 situation more specifically, several reports have shown that the stereotyping of poor people and minorities is exacerbated in times of pandemic. Indeed, as Earnshaw explains, we tend to believe that bad things happen to people we view as “bad”, a phenomenon called the “just-world fallacy”.Footnote 54 Many new manifestations of stereotypes and discrimination have also been observed since the identification of COVID-19. Xenophobia was first directed against people regarded as having “spread” the virus around the world.Footnote 55 Then, essential workers such as health workers and populations facing stereotypes and discrimination previously to the pandemic (eg people with HIV, sexual minorities, sex workers, migrants, Roma, etc.) were subjected to further stereotypes and verbal and physical abuse.Footnote 56 These people are overrepresented among socioeconomically disadvantaged populations, and their socioeconomic situation contributes in turn to the stereotypes and prejudices of which they are victims. In this context, requirements for vaccination certificates are likely to exacerbate the stigmatisation and stereotyping of the poor, even when they have a certificate. The attitudes expressed in stereotypes and stigma towards them can also trigger and worsen their own mistrust and isolation, resulting in an even higher risk of “non-take-up”, putting in danger their health and the well-being of society in general. Indeed, stigma and stereotypes during a pandemic pose a threat to everyone. Research on HIV, Ebola, Hansen’s disease, hepatitis BFootnote 57 and other infectious disease shows that stigma undermines efforts to find and treat diseases. People who fear being socially excluded if they are sick are less likely to get tested or seek treatment if they have symptoms,Footnote 58 and a vaccination certificate, whatever the extent of the obligations it represents, will act as a catalyst for this stigma, whether it is real or “only” internalised by the most vulnerable groups of our society.
V. Doubtful proportionality as regards the poor
The obligation to possess a vaccination certificate to gain access to public and private services, especially if it becomes general at some point, would make the situation of the poor untenable, especially if they become subject to fines, as in Denmark, for non-respect of such obligations.Footnote 59 The interference in the fundamental rights of these people is real and manifold and raises many concerns, not only in terms of discrimination as previously explained, but also because it is likely to affect most of their rights – political, civil and socioeconomic.
In this context, the proportionality of vaccination certificates that condition movement, but more importantly access to public and private services and work, needs to be generally questioned.Footnote 60 Indeed, although the aim of the protection of public health pursued by this system of certificates can certainly be considered legitimate, the need for such an indirect vaccination obligation to achieve this goal and its stricto sensu proportionality are far from obvious in light of the situation of socioeconomically underprivileged people: are all the activities conditioned by vaccination certificates likely to increase the public health risk if a section of the population participating in them are not vaccinated? If so, are there not less intrusive measures than certificates to achieve the same aim, such as the combination of distancing policies and an information campaign on vaccination? Are most of these individuals reluctant to be vaccinated? When dealing with the question of the necessity of mandatory vaccination in general, the WHO stated that such an obligation should be imposed only “if … [it] would increase the prevention of significant risks of morbidity and mortality and/or promote significant and unequivocal public health benefits”, if “a substantial portion of individuals are able but unwilling to be vaccinated and this is likely to result in significant risks of harm” and after having tried to address the concerns of these persons proactively.Footnote 61 It is only in these circumstances, according to the WHO, that such an obligation “may be considered ‘necessary’ to achieve public health objectives”. As for the vaccination certificate system, as an indirect obligation of vaccination, the conditions stated by the WHO have not been demonstrated so far, which casts important doubts on the proportionality of such a system. In addition, beyond the certificate system itself, there remains some doubts about the vaccines themselves, as recalled by the WHO: “a number of scientific unknowns remain concerning the effectiveness of COVID-19 vaccines: efficacy in preventing disease and limiting transmission, including for variants of SARS-CoV-2; duration of protection offered by vaccination; timing of booster doses; whether vaccination offers protection against asymptomatic infection …”.Footnote 62 In short, the vaccination certificate system is even more questionable as the data available are incomplete in terms of showing that making COVID-19 vaccination indirectly mandatory through a system of certificates would actually achieve the goal of protecting public health. As a consequence, given the importance of the rights at stake and the potentially disastrous consequences for the poor, it is doubtful that the benefits – if any – of such a system of certificates for society outweigh the individual costs for precarious people.
A recent judgment by the ECHR has dealt with this question of proportionality – although only in light of the right to a private and family life (Article 8 ECHR) – in the context of the compulsory administration of nine different vaccines for children in the Czech Republic. Parents who did not comply were respectively fined and prohibited from benefitting from nursery services for their kids.Footnote 63 In other words, the case concerned the indirect obligations to be vaccinated (ie obligations that do not directly impose an involuntary medical treatmentFootnote 64 ), such as in the case of a vaccination certificate. The Court judged that such measures did not violate the right to private and family life, without engaging with the questions raised under the right to education and the freedom of thought, conscience and religion.Footnote 65 The ECHR appears to leave a very wide margin of appreciation to the states. As critical commentators have pointed out, as well as Judge Wojtyczek in his dissenting opinion, if it is important for the Court to take a strong stance regarding vaccination, its decision is mainly based on “strong value judgments without a sufficient factual basis”Footnote 66 and its reasoning lacks coherence,Footnote 67 especially as to the necessity of the sanctions imposed on parents in light of the aim of public health protection.
This case cannot be entirely transposed to the vaccination certificate system, however, as it mainly concerned the protection of very young children: the best interests of the child were central to this case, while it has been shown that children are barely affected by COVID-19. Moreover, this ruling was only limited to nurseries – the fact that schools were not concerned played an important role in the Court’s reasoning in light of the concept of “social solidarity” (ie not contaminating other children). In addition, the Court did not tackle the flipside of the social solidarity aspect: the parents’ poverty is likely to be significantly affected by fines or the fact that nursery care was rendered unavailable to them, but this question was unfortunately marginal in the arguments brought by the applicant.Footnote 68 As a consequence, the question of conditioning the fundamental rights of the poor through an indirect vaccination obligation remains open before the ECHR. In any case, this judgment cannot be interpreted by the Council of Europe Member States as a green light to condition work, public and private services on the possession of such certificates, especially when it comes to socioeconomically underprivileged people, since the proportionality of such measures could be seriously questioned, as I have just explained.
VI. Conclusion
As Hershkoff and Cohen rightly put, “Society tries to impose on poor people – as it does on all those whom it stigmatizes – implicit conditions on how they may relate to members of the mainstream”.Footnote 69 Vaccination certificates constitute the paradigmatic example of such “phantom normalcy”,Footnote 70 which is likely to have important consequences for poor people already weakened by the pandemic, thus further crystallising their underprivileged status. In this situation, it is essential that in their assessment of the proportionality of the certificates – especially under the necessity test – courts take into account the situation of these people who are made increasingly “invisible” and might be condemned to live in a permanent state of lockdown, parked in their shelters. As recalled by the UN Committee on Economic, Social and Cultural Rights, there is a clear link between fundamental rights in general and the right to health: “The right to health is closely related to and dependent upon the realization of other human rights, as contained in the International Bill of Rights … These and other rights and freedoms address integral components of the right to health”.Footnote 71 In other words, we cannot consider the right to health in a vacuum since all of the other fundamental rights – including the rights to food, housing, work, education, human dignity, life, non-discrimination, equality, the prohibition against torture, privacy, access to information and the freedoms of association, assembly and movement – are essential to the realisation and respect of the right to health. As a consequence, in the case of people less likely to be vaccinated and to get vaccination certificates, whether this is due to accessibility, administrative issues, hesitancy, mistrust or other reasons, it is essential for public authorities to take into account the exclusionary dimension that the lack of a vaccination certificate will have, especially for vulnerable socioeconomically disadvantaged groups who have a long history of discrimination, because it raises issues under many of their fundamental rights directly linked to their right to health. In any case, instead of putting effort, energy and money into developing exclusionary and discriminatory measures such as these vaccination certificates, it seems to me much more constructive and productive to put in place a programme of prevention and education to combat COVID-19, including through vaccination.
Arundhati Roy has powerfully written: “Historically, pandemics have forced humans to break with the past and imagine their world anew … We can choose to walk through it, dragging the carcasses of our prejudice and hatred, our avarice, our data banks and dead ideas, our dead rivers and smoky skies behind us. Or we can walk through lightly, with little luggage, ready to imagine another world. And ready to fight for it”.Footnote 72 Sadly, by adopting this vaccination certificate system, the most powerful people in this world seemed to have opted for the first option, the perpetuation of inequalities and stigma against the margins of our society.
