The lives of millions of children from 188 countries who received different vaccines (diptero-tetanus-pertussis, measles, polio) were saved in the world along the time (WHO, 2017). In Romania, the antidifteric vaccination introduced in 1960 made disappear the disease in 1990. No case of diphtheria has been confirmed so far.Unfortunately, in 2016, the vaccine coverage has fallen below 90% (CNSCBT, 2017) because of either parents' refusal and the failure in attending a family doctor.Therefore, today, the society is facing a serious situation caused by: a) insufficient and erroneous information of parents expressing their opposition to vaccination and b) manipulation of organizations against vaccination.
