The report of the WHO SAGE Vaccine Hesitancy Working Group defined vaccine hesitancy as “a behaviour, influenced by a number of factors including issues of confidence (e.g. low level of trust in vaccine or provider), complacency (e.g. negative perceptions of the need for, or value of, vaccines], and convenience (e.g. lack of easy access)”.
In front of low rates of immunization, many claim for compulsory vaccination, especially as far as healthcare workers are concerned. Their institutional role and ethical purpose is to take care of a subgroup of citizens particularly weak, because of their health conditions. This is always true, but even more when immunocompromised or frail patients, vulnerable to infections, are involved. All healthcare workers have therefore a moral duty not to hurt people they have to take care of, following the ancient principle “Primum non nocere”.
