ATHENS (Reuters) - Greece plans to set up more than 1,000 vaccination centres as it awaits a successful vaccine against COVID-19, its health minister said on Wednesday. Announcements over the last two weeks that two vaccines were effective in trials have raised hope that COVID-19, which has infected 54 million people worldwide and killed 1.3 million, will be largely defeated over the coming year. Greece has seen an aggressive spike in novel coronavirus cases since early October that forced it to impose a nationwide lockdown, the second since the pandemic broke out.
