Uptake and timing of immunisations in preterm and term infants

Insights
Premature infants require timely immunisations due to higher infection risks. This study found that while overall vaccine uptake was high, preterm infants experienced significant delays in their initial vaccinations compared to term infants.
Area of Science:
- Neonatal Medicine
- Pediatric Infectious Diseases
- Public Health Policy
Background:
- Preterm infants face elevated risks of severe complications from infectious diseases.
- Prioritizing immunisation for vulnerable infant populations is crucial for disease prevention.
- Neonatal units serve as critical points for monitoring and administering infant vaccinations.
Purpose of the Study:
- To evaluate the immunisation uptake and timeliness in preterm infants compared to term infants.
- To identify potential disparities in vaccination schedules for infants admitted to a neonatal unit.
- To assess the impact of gestational age on adherence to recommended infant immunisation timelines.
Main Methods:
- Retrospective analysis of vaccination records for 110 preterm and 220 term infants over a 12-month period.
- Comparison of immunisation uptake rates and the age at which specific vaccines were administered.
- Statistical analysis to determine the significance of differences in vaccination timing between preterm and term infants.
Main Results:
- Overall immunisation uptake in the neonatal unit cohort was exceptionally high (99.93%).
- Significant delays were observed in the administration of the first three immunisations for preterm infants compared to term infants.
- Vaccination timeliness was positively correlated with gestational age, with earlier vaccines administered more consistently on schedule.
Conclusions:
- Despite high overall uptake, preterm infants experience statistically significant delays in timely immunisation, necessitating targeted interventions.
- Adherence to recommended infant vaccination schedules is critical, especially for premature and vulnerable newborns.
- Healthcare providers and parents must be educated on the importance of adhering to immunisation schedules for preterm infants to mitigate infection risks.
Abstract:
Preterm infants are more at risk of complications from infectious disease and should be immunised as a matter of priority. This retrospective study followed the immunisations given to 110 premature infants and 220 control term infants admitted to the Neonatal Unit at the Royal United Hospital, Bath over a 12-month period. The overall immunisation uptake for infants admitted to the neonatal unit was 99.93, better than for the general population of the area. However, in both preterm and term infants there were considerable variations in the age at which each immunisation was given. Fewer of the preterm infants had their first three immunisations on time. The difference in timings between the two groups was statistically significant. Earlier immunisations were more often given on time than later ones. The greater the gestational age, the more likely that the infant would be immunised at the correct times. It is important to stress to parents the importance of immunisation for babies who are born prematurely or who have been unwell.
