ATHENS — Seventy percent of citizens over 60 will have been vaccinated by the end of May, Health Minister Vassilis Kikilias said while speaking to SKAI TV on Thursday, adding that the platforms for all vaccines to younger ages will open by the end of the month.

Kikilias said that "we will continue to wear masks for a long time, particularly indoors," and expressed his optimism that conditions are improving and Greece gradually return to at least a partial normality. He noted that May will be indicative for the reduction of the new cases and those needing respiratory support," and urged all tourists to come to Greece "but with caution".

He also estimated that a wall of immunity will be built in the summer if the deliveries of the vaccines continue normally, meaning that 60-70 percent of the population will be able to get vaccinated.
