UK paediatricians' attitudes towards the chicken pox vaccine: the SPOTTY study

Objectives An effective vaccine for chicken pox has been included in immunisation schedules since the 1990s. In the UK the recommendation for routine inclusion came in November 2023; it has not yet been implemented. We explored paediatricians' attitudes towards the vaccine and their personal and professional use; as this has been shown to be an influential factor in parents' vaccine decision making.

Methods We conducted a cross-sectional online survey using a structured questionnaire exploring attitudes and knowledge towards the chicken pox vaccine of UK based paediatricians between June and September 2023.

Results We received 272 responses, 211 female (78%), 228 based in England (85%) with remainder in Wales (23), Scotland (8) and Northern Ireland (9); 150 (56%) reporting practicing paediatrics <10 years. The majority (n = 207; 78%) agreed that the chicken pox vaccine should be included in the UK routine schedule. Half the cohort, 52% (n = 135), reported having their own children vaccinated against chicken pox, 73% of those with appropriately aged children. Most, 86% (n = 225), recommended the vaccine to family and friends routinely or when asked; however, 42% (n = 108) did not feel able to advise patients' parents due to insufficient information. Of those who do not recommend the vaccine to family and friends, 22 (59%) reported insufficient information to discuss in a professional setting. Of those who did not think it should be included, or were unsure, 38/55 (69%) also felt they had insufficient information to advise parents regarding the vaccine.

Conclusions Whilst many paediatricians choose to vaccinate their children and agreed the chicken pox vaccine should be added to the routine schedule, the proportion disagreeing is not insignificant. Targeted education to improve paediatricians' knowledge of the chicken pox vaccine and their confidence discussing it should be implemented prior to the national roll out.
