RESUMO
The Regional Immunization Calendar in Calabria, a region of Italy, was updated in 2022, introducing optional co-administration of three injectable vaccines, with one oral vaccine, at 3 and 5 months old, and three injectable vaccines at 13-14 months old. In this project, the opinions and expectations of healthcare professionals (HCPs) in Calabria were investigated, with respect to the updated recommended practices. An 11-question survey was developed, which addressed concepts and topics related to immunization calendar implementation. Focus group discussions were also organized to provide further insight on the survey findings. A total of 132 HCPs completed the survey (86 public health providers [PHs] and 46 family pediatricians [FPs]). Overall, ≥50% of respondents agreed that vaccine co-administration would be advantageous for public health by reducing the number of vaccination sessions required. Most PHs and FPs agreed that dissemination of available safety data on vaccine co-administration is a necessary action to facilitate effective implementation of the strategy into clinical practice. The importance of safety data related to vaccine co-administration was supported further by discussions held in PH and FP focus groups. Overall, these findings demonstrate support from HCPs in Calabria for vaccine co-administration, and highlight key activities needed for successful uptake.
