Background Infants born preterm (prematurely) are at risk of infection, making timely vaccination vital. However, global literature suggests that preterm infants experience vaccination delays and there is a lack of evidence from the UK exploring this issue at population level.

Aim To investigate potential vaccination delays in preterm infants in one region of England and to identify characteristics related to timeliness.

Method Existing trust data sets were analysed for infants born across a six-month period in 2018. The vaccines studied were for the primary schedule (vaccines given to children at eight, 12 and 16 weeks of age).

Results The results did not fully concur with the global evidence. In this study only infants in the moderate-to-late category of prematurity received some vaccines later than full-term infants.

Conclusion Primary healthcare professionals, such as health visitors, should maximise opportunities to support parents with their decision-making around vaccination and ensure that they keep themselves fully informed about the latest vaccination guidance.
