“…As a result, a certain amount of published research has appeared, which is understandably limited both in terms of number and content due to the recent appearance of the DCC. Although the contents of the research often intertwine and touch on diverse but related issues, in our opinion they can generally be classified into three larger groups with common characteristics, namely epidemiological concerns, attitudes to vaccination, and health outcomes [ 9 , 10 , 11 ]; public health, healthcare and social policies and measures [ 12 , 13 , 14 ], and legal aspects, democratic values, and human rights [ 15 , 16 , 17 ].
