Covid-19 vaccines remain highly effective against hospitalizations and death,
even as the
more contagious
delta variant
is spreading rapidly in the United States, according to studies released Friday.
A study tracked
more than 600,000 Covid-19 cases
in 13 states from April to mid-July.
As the delta variant spread in early summer, those who weren't vaccinated were 4.5 times more likely to become infected than those fully vaccinated, 10 times more likely to be hospitalized and
11 times more likely to die
, according to the
Centers. for Disease Control and Prevention (CDC).
In the United States, the vaccination campaign continues: there are 25% who resist receiving the inoculation.

“
Vaccination works, '
' Dr. Rochelle Walensky, CDC director, said at a briefing at the White House on Friday 10th.“ The bottom line is this: we have the scientific tools we need to turn this pandemic around. ''
But as previous data have shown,
protection is declining
: It was 91% in the spring and 78% in June and July, the study found.
Cases of infections in fully vaccinated people accounted for 14% of hospitalizations and 16% of deaths in June and July, almost double than a few months ago.
This increase is not surprising: No one said vaccines were perfect, and health experts warned that as more Americans get vaccinated, they would account for a larger fraction of cases.
Walensky said on Friday that
more than 90% of people hospitalized for Covid-19
in the country are not vaccinated.
The CDC published two other studies indicating decreased protection for older adults.

It is not clear if the changes observed over time are due to the fact that
immunity is declining
in people who were vaccinated for the first time many months ago, because
the vaccine is not as effective against delta,
or because much of the country has
left. face masks
and other precautions just as the most contagious variant was beginning to spread.
But health authorities will take this into account when deciding whether Americans need a booster shot and how soon after their last dose.

Biden's outrage
The president of the United States, Joe Biden, announced on Thursday the 9th a regulation that has yet to be published and that will affect
all companies that have 100 or more employees
, in which at least 80 million people work, to be vaccinated yes or yes against covid-19.
These companies must ensure that their workers are vaccinated with the full schedule or, otherwise, force them to show a negative test result at least once a week.

The drop of the president's patience ran out due to the increase in infections, which now reach 40.7 million with 659,139 deaths, the most affected country in the world, due to the rejection of a large part of the population to be immunized.
Biden defended his new vaccine mandate on Friday against threats from several Republican governors to sue him to stop it.
"Go ahead and give it a try," Biden said during a visit to a public school in the Brookland neighborhood of Washington.
