National survey for pediatricians in Argentina: Vaccination in daily practice, perception of knowledge and barriers

Introduction. The decline in vaccination coverage has been very significant in the past decade. Pediatricians play a key role in catching-up coverage and increasing confidence in vaccination. Objectives. To describe pediatricians' perceptions of vaccine knowledge and practices and to identify barriers to access. Methods. Observational, analytical study using an online survey. Variables related to professional profile, training and barriers to vaccination were included. Results. A total of 1696 pediatricians participated (response rate: 10.7%). Their mean age was 50.4 years; 78.7% were women; 78.2% had ≥ 10 years of experience; 78.4% provided outpatient care and 56.0%, in the private subsector; and 72.5% received training in the past 2 years. Respondents described themselves as "trained" in convey the following aspects to their patients: benefits of vaccines: 97.2%; campaign objectives: 87.7%; contraindications: 82.4%; adverse effects: 78.9%; catch- up vaccination: 71.2%; reporting of events supposedly attributable to vaccination or immunization: 59.5%. The proportion was statistically higher in all aspects, among pediatricians with ≥ 10 years of experience and those who received training recently (p ≤ 0.01). The barriers identified in access to vaccination were false contraindications (62.3%), temporary vaccine shortage (46.4%), cultural reasons (41.4%), and restricted vaccination center hours (40.6%). Conclusions. The perception of the level of training varied depending on the vaccination-related aspect. Pediatricians with more years of professional experience and those who received recent updates perceived themselves as more trained. Multiple barriers associated with access to vaccination were identified.
