ABSTRACT
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.
