BACKGROUND
Influenza is a major cause of morbidity, mortality and exacerbation of extant chronic disease worldwide. Influenza vaccination is thus fundamental to reduce the burden of disease. In this study, we describe the trend of influenza vaccination coverage in the seasons 2010/11-2020/21 among children aged < 2, 2-4 and 5-8 in Italy.
METHODS
We analyzed the trend of influenza vaccination coverage in the pediatric population in Italy from the 2010/11 to the 2020/21 season at national and regional level and observed the incidence of influenza-like illness (ILI) in the pediatric population between 2010/11 and 2020/21.
RESULTS
In the period 2010/11-2019/20 the highest value of coverage (4.5%) was reached in the age group 2-4 and 5-8 (season 2010/11 and 2011/12, respectively), while the lowest belonged to the < 2 group (1.1% in the season 2015/16). In the season 2020/2021 all the age groups reported a substantial increase of coverage compared with the previous season. The highest value (19.0%) was reported in the age group 2-4, followed by the group 5-8 and < 2 (13.1 and 9.2%, respectively). Considering the rates of annual ILI cases, the highest value for the 0-4 age group was 18.5% in the 2011/12 season; for the 5-14 age group, the highest value was 27.7% in the 2010/11 season.
CONCLUSIONS
Over the past 11 years pediatric influenza vaccination coverage in Italy has been low, with relevant differences across regions and seasons, albeit a general increase in coverage has been observed in the 2020/21 season. Universal influenza vaccination for children should be considered as a priority for the high incidence in this age group. Further research is needed to improve knowledge and comparability of coverage rates, and to identify the best practices for organizational models of delivery which can support the improvement of trends, the acceptability and accessibility by parents and awareness in stakeholders and decision makers.
背景
流感是导致全球发病率、死亡率和现有慢性病恶化的主要原因。因此，接种流感疫苗对于减轻疾病负担至关重要。本研究描述了 2010/11 年至 2020/21 年期间意大利<2 岁、2-4 岁和 5-8 岁儿童流感疫苗接种覆盖率的趋势。
方法
我们分析了 2010/11 年至 2020/21 年期间意大利全国和地区的儿科人群流感疫苗接种覆盖率趋势，并观察了 2010/11 年至 2020/21 年期间儿科人群流感样疾病（ILI）的发病率。
结果
2010/11 年至 2019/20 年期间，2-4 岁和 5-8 岁年龄组（2010/11 年和 2011/12 年）的覆盖率最高（4.5%），而<2 岁年龄组的覆盖率最低（2015/16 年为 1.1%）。2020/21 年，所有年龄组的覆盖率与前一季节相比均有大幅增加。2-4 岁年龄组的覆盖率最高（19.0%），其次是 5-8 岁年龄组和<2 岁年龄组（分别为 13.1%和 9.2%）。考虑到每年 ILI 病例率，0-4 岁年龄组的最高值为 2011/12 年的 18.5%；5-14 岁年龄组的最高值为 2010/11 年的 27.7%。
结论
在过去的 11 年中，意大利儿科流感疫苗接种覆盖率较低，各地区和各季节之间存在显著差异，但在 2020/21 年，覆盖率普遍有所增加。应将儿童普遍接种流感疫苗作为该年龄段高发率的优先事项。需要进一步研究以提高覆盖率的知识和可比性，并确定最佳的实施模式，以支持改善趋势、提高家长的可接受性和可及性以及利益相关者和决策者的意识。
