Greek Prime Minister Kyriakos Mitsotakis announces that beginning on November 22, unvaccinated people will be banned from entering all indoor venues for which they could previously present a negative test result, due to an increase in new COVID-19 cases. Mitsotakis also announces that vaccine passports will expire after seven months for people over the age of 60 years and urges people in this age group to receive a booster dose.
