The country is big, with a big enough population, highly movable/mobile, slow vaccination and at least 3 native variants that are more dangerous than the original one. Very good conditions for the emergence of new resistant variants. What is scaring the world the most now is the possibility of a new brazilian variant that can escape current vaccines. That would move the whole world to the beginning of the pandemic again.
