BACKGROUND
A large percentage of the population has not yet started vaccination, for which the increase in coverage is almost null.
METHODS
We used segmented regression analysis to estimate trends in the first dose coverage curve.
RESULTS
There has been a slowdown in the application of the first doses in Brazil since epidemiological week 36 (average percent change [APC] 0.83%, 95% confidence interval [CI] 0.75-0.91%), with a trend close to stagnation.
CONCLUSIONS
It is important to develop strategies to increase access to vaccination posts. Furthermore, it is recommended to expand vaccination to children, thereby increasing the eligible population.
背景
很大一部分人群尚未开始接种疫苗，因此覆盖率的增加几乎为零。
方法
我们使用分段回归分析来估计首剂疫苗覆盖率曲线的趋势。
结果
自第 36 周（平均百分比变化 [APC] 0.83%，95%置信区间 [CI] 0.75-0.91%）以来，巴西的首剂疫苗接种速度放缓，趋势接近停滞。
结论
开发增加疫苗接种点可及性的策略非常重要。此外，建议扩大儿童疫苗接种范围，从而增加目标人群。
