Vaccination status is more often evaluated by up-to-date vaccination coverage rather than timeliness of immunization. Delaying vaccination may be dangerous during infancy. The aim of this study was to identify the importance of potentially dangerous vaccination delay (previously defined) and determinants of these delays. We conducted a national, prospective, vaccination survey in June 2014, with primary care pediatricians. Children, 2 to 24 months of age, were included. Data about vaccination were extracted from their health books. Additional data were collected through a standardized questionnaire. Vaccine coverage rate and timeliness were calculated. Variables associated with a potentially dangerous vaccination delay as previously defined were determined by a multivariable analysis. Among the 443 included children (mean age 10.8 months, 49% males), 13% to 58% of vaccine doses according to vaccine type were done with a potentially dangerous delay. Globally, 47% of children had at least one potentially dangerous immunization delay. We identified two risk factors of potentially dangerous delayed immunization globally: an increasing age of the child (adjusted odds ratio: 1.2, 95% confidence interval [CI]: 1.1-1.3, p < 10), and a working mother (adjusted OR: 2.4, 95% CI: 1.2-4.7, p = 0.01). Despite a good vaccine coverage rate, a large number of children had a potentially dangerous vaccination delay. A high level of vigilance regarding these immunization delays, and particularly to the patients sharing the risk factors of immunization delay identified here, can increase quality and effectiveness of the vaccine protection.

“…Although vaccines have saved many lives, a growing number of people worldwide believe that they may be harmful. 1 This was reflected by a steadily decrease in vaccine coverage in Western countries (especially in the US) in the last decade, and resultant outbreaks of some vaccine-preventable diseases, such as pertussis, 2 measles, 3 , 4 and poliomyelitis. 5 The growing popularity of anti-vaccination attitudes stimulated progressive development of pro-vaccination movements (like VaccinateCalifornia 6 ), since many well-educated people realize potential harmful social consequents of decreasing vaccine coverage in children and adults.…”

Anti-vaccination movement has existed as long as the vaccines themselves, but its mode of action and social influences evolved over time. Such attitude with no doubt has negative impact on vaccination rates and eradication of infectious diseases. In this study, we used an online survey to examine vaccination attitudes of Polish university students of various degree and specialties. A total of 1,386 questionnaires were completed, among them 617 from students attending medical schools and 769 from students of non-medical schools. Up to 95.24% (N = 1320) of the study subjects, among them 98.70% and 92.46% of students of medical and non-medical specialties, respectively, declared willingness to vaccinate their children. 47.19% (N = 654) of participants have a contact with anti-vaccination propaganda at least once in a lifetimes. 42.64% (N = 591) of respondents were aware of the existence of anti-vaccination movements; 45.35% (N = 414) of participants, including 306 (51.52%) and 108 (33.86%) students of medical and non-medical disciplines, respectively, considered such movements as a negative phenomenon. Vaccination attitudes of students from medical and non-medical universities differed considerably. Vaccination knowledge and awareness among the students from non-medical universities were rather poor, markedly lower than in the students of medical disciplines. Nevertheless, irrespective of their major, Polish students have considerable knowledge gaps with regards to vaccination and need additional education in this matter.

“…For instance, a child with an NME from the measles, mumps, and rubella (MMR) vaccine is 35 times more likely to contract measles than is a vaccinated child [ 4 ]. Moreover, a child without the diphtheria, tetanus, and acellular pertussis (DTaP) vaccine is 3 times more likely to contract pertussis than is a vaccinated child [ 5 ]. NMEs weaken herd immunity that protects the population at large, particularly children who are unable to get vaccinated for medical reasons.…”
