Abstract

Introduction: The COVID-19 pandemic has severely impacted routine immunization activities and a decline in vaccination coverage has been documented around the world. The aim of this study was to assess the impact of the direct and indirect effects of the COVID-19 pandemic on routine childhood vaccination coverage in the Province of Siracusa, Italy.

Methods: We compared 2020 and 2019 vaccination coverage by age group and vaccine type. Results were considered statistically significant at a two-tailed p-value ≤ 0.05.

Results: Our findings show that vaccination coverage rates for mandatory and recommended vaccinations decreased in 2020 compared with the previous year (range from -1.4% to -7.8%). Anti-rotavirus vaccination increased (+4.8%, as compared to 2019), while the reductions observed for polio vaccination (hexavalent) and human papillomavirus vaccination in males were not statistically significant. The reduction did not hit the population in the same manner, with the greater decreases observed for children aged > 24 months compared to the younger (-5.7% vs -2.2%) and for booster doses compared to the primary vaccinations (-6.4% vs -2.6%).

Conclusions: This study found that vaccination coverage of routine childhood immunisations was negatively affected during the COVID-19 pandemic in the Province of Siracusa. It is of huge importance to put in place some catch-up programs to ensure vaccinations at the earliest of individuals who missed immunization during the pandemic.
