ATHENS – Life will get tougher for Greece's unvaccinated on Sept. 13 – unless they have fake certificates showing they are inoculated – as measures keeping them out of  closed space go into effect to try to slow COVID-19's spread.

That's when schools open as well and the New Democracy government and its advisory panel of doctors and scientists giving advice on how to handle the spreading pandemic will be watching for outbreaks.

The number of cases and hospitalizations has started to level off even though the Delta Variant makes up all of them and is targeting the unvaccinated, but fears remain of a fourth wave in the autumn because of anti-vaxxers and people defying health measures who aren't wearing masks or staying apart.

Those who aren't vaccinated will be required to have one or two tests weekly depending on their profession or business, at a cost of 10 euros ($12) in private clinics for rapid tests up to 60 euros ($71) for molecular tests.

Unvaccinated employees, both in the private and public sectors, must be tested once a week, at their own expense while in other groups, such as teachers, university academics, employees in tourism and those taking part in TV, theater, music and dance productions it's twice.

Entry to closed workspaces, entertainment, culture and sports venues requires either a vaccination certificate, a certificate that the person has recovered from the disease or a negative test result, the paper added.

Employers also have the right to demand of workers proof of vaccination and people who aren't vaccinated will not be able to get free tests while masks are required at outdoor gatherings, which has still largely been ignored.
