Diphtheria-tetanus-pertussis (DTP) combination vaccines are a cornerstone of infant vaccinations worldwide. DTP vaccine acceptance could be impacted by sub-optimal relationships between parents and healthcare professionals (HCPs). This survey, conducted in France and India between 14/2/2020 and 26/3/2020, aimed to understand perspectives and expectations of parents and HCPs toward DTP vaccination. Participants were parents (parents/guardians of ≤3-year-old children; France: n = 1002, India: n = 1021) and HCPs (general practitioners/pediatricians initiating DTP vaccination; France: n = 300; India: n = 300) who chose to take part. A representative sample of parents was achieved via quotas and random iterative weighting to match key demographics of the target population. In India, only parents from socio-economic classes A/B/C and private HCPs were included. Whilst DTP vaccine acceptance was high among parents in France (85%) and India (98%), French HCPs overestimated parental acceptance (99% thought parents were very/fairly accepting). The proportions of parents reporting that the HCP is someone they trust versus the proportions of HCPs wanting to be seen as trusted were discrepant in France (76% versus 90%) but not India (83% versus 85%). Some surveyed parents indicated that, ideally, they would like some input in vaccine brand decisions alongside HCPs, an opinion shared by some HCPs. In France, short-term experience post-vaccination was more important to parents than HCPs, for whom long-term protection was more important. In India, these aspects were equally important to both. Increased awareness of parents' priorities and concerns regarding DTP vaccination can support HCPs in their discussions with parents and help build trust, which may impact vaccine acceptance.
