g. whether they had vaccinated their own child) – though professional experience, particularly

from a practitioner with a long career and a history of providing useful advice, moved some parents. If I’d have been against it, [GP saying he’d vaccinated his own child] would not have swayed me at all. I’d say, thank you very much but that might be for you. I’m not sure it’s for me. I’m not ready to make that decision yet. (P4, MMR1 on-time) MMR1-accepting parents used trust in their health professionals both to minimise the complexity of influences Epigenetics inhibitor on their decision by reducing the need to seek and evaluate alternative sources of advice, and to minimise anticipated regret by ‘sharing’ the decision (therefore the blame for any negative outcomes) with an expert. If something went wrong with the vaccine at least I Modulators listened to, I read all the information, listened to someone that knows a lot more than I do and if that was meant to be then I feel that that was meant to be but I wouldn’t want to take all the responsibility Gemcitabine mouse on myself by choosing not to vaccinate my children

(P12, MMR1 late) Most parents rejecting MMR1, and some opting for single vaccines, spoke of their health professional questioning their decision at most appointments, or their practice sending repeated MMR reminders. For some parents these interventions created trepidation around interaction with their clinician, whilst for others they were little

more than an irritation; parents in the latter group linked their ability to deflect these approaches to their confidence in their decision. I always get the speech no matter what I’ve gone in for so even if we’ve gone in for an ingrown toenail I get the speech… ‘Have we talked about his immunisations yet?’ (P19, no MMR1) Some parents identified a distinction between health professionals’ advice supported by provision of facts/information, and advice with no supporting evidence or rationale: isothipendyl the latter was of no use to them during decision-making and in some cases damaged their relationship with their clinician. I did go to the doctor and ask them [for advice about egg allergy] and they just said yeah, you should definitely give them the MMR… that was their information they gave me… it was more ‘don’t be so stupid’ actually I would say (P18, no MMR1) Parents’ views on disease severity often appeared rooted in personal experience rather than population-level statistics. MMR rejectors talked about how these diseases can be treated and prevented through lifestyle measures, whilst these factors did not enter the narrative for most MMR acceptors. The benefits of natural immunity were felt more keenly by MMR rejectors than MMR acceptors, though parents across decision groups were aware of the natural immunity debate. Many parents across decision groups had experienced measles, mumps and rubella in themselves or their siblings as children.
