Aim: To explore child health professionals' experiences of the early implementation of the rotavirus vaccination in the two regions that first introduced this vaccination in Sweden.

Methods: A descriptive and repeated cross-sectional study based on a digital study-specific questionnaire with a baseline in 2014 and with a 2-year follow-up in 2016. The study population consisted of nurses and doctors working in child health centres in the health care regions of Stockholm and Jönköping.

Results: In Stockholm, a larger proportion of the respondents (n = 355) had concerns in 2014, in comparison with the respondents in Jönköping (n = 101), mostly about the vaccination being a new and time-consuming task (60% versus 23%). In 2016, the overall attitude to vaccination was more positive in both regions and the levels of concern about increased workload were reduced (Stockholm, n = 519, 39%, versus Jönköping, n = 96, 10%). Challenges before and after the introduction in both regions were particularly related to how to give information about the vaccine's potential increased risk of intussusception.

Conclusion: The gap between respondents' knowledge, attitudes and concerns pre- and post-vaccination introduction was larger in Stockholm compared to Jönköping. In both regions, overall, the implementation of the rotavirus vaccination was perceived as being easier than expected.
