During the COVID-19 pandemic, recommendations for maintaining physical distance, restricted mobility measures, as well as fear of mass transmission by going to health centers have significantly contributed to the general vaccination coverage, which by and large is decreasing worldwide; thus, favoring the potential re-emergence of vaccine-preventable diseases. In this study, we have used the existing data on vaccination coverage during the pre-pandemic (2019) as well as the pandemic (2020) period to evaluate the impact of coronavirus outbreaks during the vaccination drive in Brazil. Furthermore, we have accumulated data since 2015 among the different regions of the country to acquire more consistent information. The various vaccines analyzed in our study were meningococcal C conjugate, Triple antigen vaccine, 10-valent pneumococcal conjugate, and BCG; subsequently, the data were obtained from the National Disease Notification System. This study revealed that the ongoing immunization drive saw a steep decline of around 10 to 20% during the (2019-2020) pandemic period in Brazil. These results provide strong evidence towards the decreasing trends following the vaccination programs during the COVID-19 pandemic period in Brazil. Furthermore, our results also highlight the importance of adopting widespread multi-component interventions to improve vaccination uptake rates.
在 COVID-19 大流行期间，保持身体距离、限制流动性措施以及担心前往卫生中心会大规模传播的建议，极大地促进了全球范围内普遍接种疫苗的覆盖率，而这一覆盖率在全球范围内正在下降；因此，有利于疫苗可预防疾病的潜在再次出现。在这项研究中，我们使用了大流行前（2019 年）和大流行期间（2020 年）的现有疫苗接种覆盖率数据，来评估 COVID-19 爆发对巴西疫苗接种运动的影响。此外，我们自 2015 年以来在该国的不同地区积累了数据，以获取更一致的信息。我们研究中分析的各种疫苗包括脑膜炎球菌 C 结合疫苗、三联抗原疫苗、10 价肺炎球菌结合疫苗和卡介苗；随后，数据来自国家疾病通报系统。这项研究表明，在巴西（2019-2020 年）大流行期间，正在进行的免疫接种运动急剧下降了约 10%至 20%。这些结果为巴西 COVID-19 大流行期间疫苗接种计划后呈下降趋势提供了有力证据。此外，我们的结果还强调了采取广泛的多组分干预措施来提高疫苗接种率的重要性。
