Hi ioanniskefalas , Kali mera :-) , well i wished i was wrong , but it seems to go from bad to worse , natural immunity seems to be the best option for now against this nightmare.Data in regard to unvaccinated & virus as well as variants grows by the day , Delta spreads like chickenpox !! Avoid crowds and have a mask !! Just my Opinion !! Stay away from the jab if you can, if you want it your choice , the jabbed themselves seem to produce the variants and can transmit asymptomatic , Israel 2/3 of infected in hospitals are double jabbed , and the same trend goes for every f-ing place globally with high vax-rates , even cruise ships with all vaccinated on board fall ill , since the jab is wearing off in 4 - 6 months . I lack newest data from greece regarding vaccination level & rules you have .
