  1. Regarding lowering the 4th vaccine dose to the age of 50, does that mean it would be mandatory and we would be fined if we don’t get it? Is that what is on the table? Or is it simply going to be a recommendation?
    Also, if so, after how many months from the third vaccine should the 4th be taken, according to the Greek government?
