Greece has made vaccinations against COVID-19 mandatory for certain workers and announced restrictions to contain the spread of the virus as infections have kept rising during the vital summer tourism season.

"The country will not shut down again because of some," Greek Prime Minister Kyriakos Mitsotakis said in a televised address announcing the measures.

Nursing home staff will need to get vaccinated immediately, while healthcare workers will have to be vaccinated starting September 1, Mitsotakis said.
