Fiji announced Covid-19 mandatory vaccination in July where public servants were told they would need to be fully vaccinated.
Prime Minister Frank Bainimarama directed this section of the workforce to vaccinate against the virus by November 1 or face losing their jobs.
He said people who received the state benefits would also need to get the jabs.
Workers rights' advocates and legal experts in Fiji had labelled the government's Covid-19 response as being "more of a fire brigade approach" and that it was not in control of the fight against the deadly virus.
Suva lawyer Jon Apted said the issue during the Covid-19 pandemic was how far and in what circumstances the requirement for a person to be vaccinated as a condition of some benefit could be imposed by a State, an employer, school or public person like a retailer or shop.
Apted highlighted this during an online annual lecture series organised by the Citizen's Constitutional Forum (CCF).
He said compulsory vaccination against smallpox began in 1853 in England, and the US Supreme Court upheld compulsory smallpox vaccination in 1905.
But following World War II and the Nuremberg experiments, a new right was introduced and that right was now reflected in Fiji's Constitution.
"The freedom from medical experimentation, scientific treatment and medical treatment without your consent, so this is the novel area."
Apted said the coronavirus was the 'first real international pandemic' since the right had come to be recognised.
He said many countries had accepted they could impose it, not as a requirement for compulsory vaccination "but as a mandatory condition for certain things".
Fiji is expected to reopen its borders to fully vaccinated international travellers in November.
