Concerns are growing about the delta variant of the coranavirus, 
the indication is that some vaccines may not be fighting this variant, the growing number of infections, even in countries with advanced vaccination, is worrying.
WHO Director Tedros Ghebreyesus said two days ago to various media outlets at a press conference: “New cases of contamination and deaths continue to rise. There were 4 million new cases in one week. At this rate, we will surpass the mark of 200 million of infected in two weeks, although we know that this is an underestimated number”, he pointed out.
Since the third week of July, Europe and the United States have again registered an increase in infections due to the delta variant.
Even in China, which had controlled the pandemic, this number grew again, still small (200 cases), but it is already spread over several regions. peoples in dangerous cities will be tested.
In Brazil the moving average is below a thousand daily deaths, it slowly drops as vaccination progresses, but cases of the delta variant already appear in the country, and the real effectiveness of the vaccine in relation to this variant is concerned, there is poor monitoring in some states, testing should begin immediately and en masse, there is no evidence.
The idea of making the measures more flexible continues and will probably not go back until another outbreak, only one state (Rio de Janeiro) registers an increase, 8 states in stability and 15 in decline (São Paulo is one of these).
The WHO and the World Bank call for the urgent application of vaccines in poor countries, the average in high-income countries is the application of 98.2 doses per 100 inhabitants; while in low-income groups, the number is 1.6 doses per 100 people.
Regardless of the effectiveness of vaccines, vaccination must continue and so must restriction.
