Introduction
Today, mixed debates exist regarding mandatory childhood immunisation (Williamson & Glaab,
2018; Giubilini, 2019). As such, vaccination creates ethical challenges as they often involve mass
immunisation, including with children where parents play an important role in decision-making. Whereas
mandatory vaccination in Australia is well intentioned, such policies and legislation can serve to
contravene bioethical principles which are often meant to promote safe and quality healthcare. When
treating children of vaccine-hesitant parents, each situation is unique and ought to have a personal and
individual approach. This paper draws on the bioethical principles attempting to examine whether
childhood vaccination should be mandatory in Australia.
Mandatory Vaccination Contravening Bioethics
Australia has a nationally mandatory vaccination program combined with school entry
requirements which have traditionally been in place and deny childcare benefits and access to family
assistance to those who refuse vaccines, unless they present proof of exemptions (Services Australia,
2021; Department of Health (DoH), 2022). Subsequently, there exist related ethical challenges within
healthcare environments (Williamson & Glaab, 2018; Giubilini et al., 2018; Giubilini, 2019; Wilkinson &
McBride, 2022). As such, when vaccinating children at the individual level, conflicts can exist between
respecting the best interests of the child, the autonomy and self-determination of the parents, and just
contribution of herd immunity (Giubilini et al., 2018; Rus & Groseli, 2021). Respect for autonomy and
patient self-determination is one of the most crucial principles of bioethics and has been well embraced in
the developed world. Autonomy in the Western world has meant that individuals can engage in
autonomous decision making about their healthcare and about the health of their children which is
reflective of their values, wishes, and needs. Mandatory immunisation infringes the upholding of this
principle.
In Australia, Australians have to either choose between accepting immunisation for their children
or forego significant family tax and childcare benefits and refusal has been associated with financial
penalties in a context where most of the families are unable to provide adequate childcare in the absence
of these benefits; through the ‘non jab no pay’ policy (Holden, 2016). Kirby (2017) reported that several
states in Australia proposed laws imposing hefty fines on kindergartens that enrol children who have not
been vaccinated without valid medical exemption. What happens then, to the voice of the parents in
shared decision making and the lives of young children who need care? Furthermore, human dignity is an
important concept of bioethics and comes into play here. Human dignity recognises that human beings
need to be treated with respect irrespective of their ethnicity, gender, status, ability, age, and so forth and
they possess a special value intrinsic to their humanity and are worthy of respect. Critics of mandatory
vaccination argue that such policies deny parents the right to conscientious objection thus failing to
observe their human dignity (Balák, 2014; Bonanni, 2018; Harmon et al., 2021).
Proponents of vaccination have argued that compulsory vaccination drives are in the best interests
of the child. The principle of justice can be examined within the context of herd immunity, according to
Rus and Groseli (2021). This principle calls for just contribution to herd immunity and contravenes the
upholding of parental autonomy and self-determination. Herd immunity is often regarded as a common
good and perhaps a right promoted by the law of the land. As such, in terms of promoting the principle of
justice, Rus and Groseli (2021) ague that ‘negative’ policies for vaccination such as vaccination mandates
for kindergarten, penalties for refusal and laws are justifiable in order to protect vulnerable subjects
especially when herd immunity is endangered and moral duty of individuals (such as parents of
unimmunised children) to contribute to the common good has not been fulfilled. This here points to the
possibility of an ethical dilemma between the principles of justice and autonomy which would be
contradicting each other.
Vaccine hesitancy can be particularly a complex issue and cannot just be addressed simply by
coercion or coercive policies. Diseases such as measles which had been dreaded in the past are no longer
feared by parents, even though this is not meant to downplay or dismiss the devastating impacts that such
diseases can have if they were to emerge. Such diseases as measles have been successfully controlled
through vaccination and it can be argued that fear by parents has shifted to the vaccines from fearing such
diseases. Vaccines are not perfect despite remarkable safety record. Moreover, many safety concerns that
parents may have still remain unaddressed or unresolved and governments have been criticised for a lack
of effective and efficient tools at the macro, messo and micro levels aimed at addressing vaccine
hesitancy, for instance among parents. Today, the hypothesised association between autism and measles,
mumps, rubella (MMR) vaccine continues to contribute to concern and fuel vaccine hesitancy, with such
myths propelled by misguided science but proving to cement anti-vaccination beliefs among the public
(Hviid et al., 2019; Davidson, 2017). Additionally, low trust placed on governments that buy, promote
and impose mandatory vaccines as well as pharmaceutical companies that manufacture these vaccines
cannot be simply overlooked. As such, on top of the failure to address such concerns, exclusively
mandatory policies and legislation which promote coercive vaccination may appear draconian and have
the potential of doing more harm than good. They may even exacerbate vaccine hesitancy amongst
parents who may be forced to become more opposed to vaccination.
Whereas times have changed, lessons can be learnt from historical events when mandatory
vaccinations have been put in place and the outcome of such, especially when aspects such as autonomy
and self-determination of people did not mean a thing. Studies by Adedeji (2021) and Weiss and Esparza
(2015) have cited the Vaccination Act of the 1840s and 1850s in the United Kingdom, for instance the
Vaccination Act of 1953 which instituted mandatory vaccination. Defaulting parents were made liable for
imprisonment or fine and mandatory vaccination was extended to the age of 14, with cumulative penalties
for non-adherence (Adedeji, 2021). What followed was the anti-vaccination resistance movements with
several occasions leading to violent demonstrations. The UK had to establish a new law and resorted to
conscientious exemption. Consistent with arguments made by Salmon et al. (2015), perhaps policy
makers and key decision-makers might consider learning from history on the impacts that mandatorily
and coercively imposing immunisation on parents and children and ignoring their voices and disregarding
their concerns. This might be helpful in ensuring that history is not repeated from counterproductive
policies.
Ethical justification for mandatory vaccination
Nonetheless, proponents of a utilitarian approach would argue in support for parental moral
responsibility to vaccinate their children in order to achieve herd immunity (Giubilini et al., 2018). Their
argument is consistent with the need to promote the principle of justice whereby this can be achieved
through compulsory and mandatory immunisation. Giubilini et al. (2018) draw on the principle of ‘group
beneficence’ that is the basis of the utilitarian ethical approach which informs their argument noting that
individuals, in this case parents, have a moral obligation to contribute to herd immunity. Parents can
demonstrate adherence to this moral obligation by allowing for their children to be vaccinated on the
foundations of mutual duty to ease rescue and of a ‘fairness’ principle in distributing the burdens that is
involved in collective duty (Giubilini et al., 2018). Utilitarianism focuses on the betterment of the society
as a whole and utilitarian ethicists are concerned with increasing the net utility (Gensler, 2017). As such,
in the case of mandatory immunisation, a utilitarian ethicist would argue that ‘the end justifies the means’
drawing on their consequentialist orientations that people only have one basic duty: to maximise long-
term good consequences (Gensler, 2017). As such, they would see the benefits of vaccination as being
sufficiently large for the society thus justifying an obligation for parents to vaccinate their children.
Special situations such as the advent of a devastating disease that is vaccine-preventable, might
justify the introduction of a mandatory immunisation program, if the disease were adequately severe and
the vaccine effective and safe (Isaacs, 2012; Jennings et al., 2016; Rus & Groselj, 2021). During such
circumstances, a public health perspective triumphs over an individual-centred approach where autonomy
and self-determination of parents, for instance, is less of a priority. A good example is the emergence of
the recent Covid-19 pandemic which has tested the limits of mandatory vaccination policies globally and
revealed the extents to which vaccine hesitancy can go, including in Australia (Attwell et al., 2021;
Edwards et al., 2021). Nonetheless, there is a likelihood that voluntary vaccination would increase and
possible render coercion needless. There is a possibility that levels of immunisation might decline given
the mistrust and that the ethical justification for compulsion might be altered by the altered risk-benefit
ratio. This is particularly evident in the case of Covid-19 vaccination drives.
It is important to consider voluntariness, understanding, adequate information disclosure, and
decision-making capacity. The voices of parents and children matter. Given that most parents who are
vaccine-hesitant are sometimes misguided or lack reliable knowledge about immunisation, engaging them
in open conversations about possible risks and their dilemmas can help them consent to vaccination, for
instance in the case of MMR vaccine (Greenberg et al., 2017; Hviid et al., 2019; Davidson, 2017). It is
also critical to acknowledge the ‘controlling impact’ of anti-vaccination movements, conspiracy theories,
and other people’s opinions which limit parental self-determination. A systemic approach to
immunisation education and better communication at all levels can help solve these dilemmas and reduce
the levels of coercion which may not be exclusively necessary. Importantly, the principle of veracity calls
for healthcare workers to be honest and engage in truth-telling in all their interactions with clients (Amer,
2019). To engage parents in shared decision-making and ensure they make informed decisions and
encourage them to engage in voluntary vaccination, healthcare workers can also adhere to this principle
when educating parents on matters concerning vaccines such as benefits, risks, their rights, and so forth.
Conclusion
This paper has examined whether childhood vaccination in Australia should be necessary. It
argues that mandatory immunisation work to contradict bioethical principles which are often meant to
promote safe and quality healthcare, including examples of self-determination and autonomy for parents.
Mandatory vaccination also creates ethical dilemmas for healthcare workers, for instance when parental
autonomy contradicts with the need to uphold the principle of justice in pursuing herd immunity and
ensuring parents exercise their moral obligation, a duty that utilitarian ethicists expects of them. Heeding
to the voice of parents and educating them can help with addressing this conundrum.
