Prime Minister Scott MorrisonĀ took many people by surpriseĀ this week when he said a COVID-19 vaccine would be āas mandatory as you could possibly make itā.

Although he laterĀ backtrackedĀ on the use of the word āmandatoryā, he made clear the government is aiming for a 95% vaccination rate in Australia.
There appears to be strong community support for the vaccine, but it is not yet clear there will be enough people willing to take it voluntarily to reach that target. Therefore, it is likely there will have to be some sort of incentive or compulsion by the government to ensure nationwide compliance.
What, then, are the legal limits to compelling people to be vaccinated? There are myriad questions that could be raised, such as:
This is an important debate we need to have about how to balance the rights of the community versus those of the individual in a public health emergency and how the law should be used to ensure the efficacy of a COVID-19 vaccine.
The right to bodily integrity is a fundamental legal principle in Australia. This means a person cannot be subject to medical treatment without consent.
However, there are exceptions to this under state and territory public health laws. For instance, sections 116 and 117 of theĀ Victorian Public Health ActĀ permit public health orders to compel people to undergo a medical examination, testing and treatmentĀ without consentĀ if it is required to address a public health issue.
There may be a legal argument here that a vaccination is not ātreatmentā. But that could be dealt with via an amendment to the legislation.
There is a strong case for requiring particular workers (for example, those in aged care facilities) to be subject to mandatory vaccinations. However, many other workplaces in Australia may also require COVID-19 vaccination certificates under Occupational Health and Safety policies.
The legal dynamics here are different to a government-mandated vaccination if it is required as a condition of employment (which is a private law matter).
There is precedent for this: some states and territories have adopted a mandatory vaccination policy for staff working in close contact with patients or infectious materials. In the ACT, for example, all ACT Health staffĀ are subject toĀ an āoccupational assessment, screening and vaccination procedureā, which requires them to be immunised against diseases including influenza, diphtheria and hepatitis B.

Similarly, businesses could require an immunisation card to be presented as a condition of entry. This could include airlines requiring proof of vaccination as evidence of āfitness to flyā.
There are more complex legal questions when it comes to requiring vaccines for students to be admitted to schools or universities.
This was hotly debated inĀ those statesĀ that introduced a āno jab, no playā mandatory vaccination regime for access to child care services, as well as the federal āno jab, no payā policy.
Despite differing rules around the country, all states and territoriesĀ have fairly consistent rates for childhood vaccinations ā with a nationwide coverage rate of 91 per cent. Whether the same rate could be reached for a COVID-19 vaccine remains to be seen.
Challenges could be made to any compulsory COVID-19 vaccination policy under the human rights charters in Victoria, Queensland and the ACT, which aim to protect rights such as freedom of expression, thought, conscience, religion and belief.
Here, much will depend on who is requiring the vaccination (a public body or private business) and whether there are punitive measures in place for non-compliance (for example, the use of fines or imprisonment).
If there are punitive measures for non-compliance, these may be deemed as disproportionate by a court ā even if it could be argued compulsory vaccines are necessary and reasonable for public health reasons.
The use of compulsory vaccination programs also has specific implications for childrenās rights. TheĀ UN Convention on the Rights of the ChildĀ provides that every child has the right to āthe enjoyment of the highest attainable standard of healthā.
However, children also have the right to an education. Therefore, punitive measures to compel parents to vaccinate their children against COVID-19, such as keeping them out of school, could violate the core principles of this convention.
There is no recognised right to conscientious objection to vaccinations under Australian law. Therefore, any person who is not willing to be vaccinated cannot merely argue an āobjectionā to it.
A religious body, however, may be able to argue a federal compulsory vaccination policy interferes with theĀ freedom of religionĀ protections under the Australian constitution, but that is a complex legal question.
One religious groupĀ did successfully claimĀ an exemption to mandatory childhood immunisations ā the Christian Scientists. This āconscientious objectionā exemption wasĀ removedĀ in 2016, but it does provide an example of how such an exemption could be dealt with under the law.

Governments clearly have an obligation to protect the publicās health and welfare and vaccinations are an important means of ensuring this.
But while punitive legal measures such as fines may be effective in compulsory mask usage, they are not necessarily going to be effective when it comes to something much more invasive like a vaccine.
Serious thought must not be given just to what the law can do to achieve a high COVID-19 vaccination rate, but also what good law is. That is, we must pursue measures that will be sufficiently accepted by the community.
