From January 17, older people in Greece that are not vaccinated face monthly fines, Euronews reports.
Those over the age of 60 and without the jab will have to pay a €50 penalty in January, rising to €100 in February.
The decision comes as the country's public health system struggles to cope with an increase in cases and the government starts to run out of patience with those who are still unvaccinated against COVID-19.
However, the lack of available vaccine appointments has left some feeling frustrated.
Medical professionals who are not vaccinated have also been suspended and face the prospect of being sacked if they fail to comply with rules which say they require vaccination.
On Sunday, Greece reported 10,783 new daily infections. Around 67% of the population is already fully vaccinated, 18,3 million vaccine doses have been distributed, and almost 22,000 people have died of COVID-19 since the beginning of the outbreak.
