In the United States, citizens were given more than 250 million vaccines against the coronavirus two weeks after the country passed the 200 filing milestone, a promise made by President Joe Biden.
This means that around 57 percent of American adults have received at least one dose of the immunizer, while 42 percent of those over 18 are already fully vaccinated.
For those over 65, the number of people vaccinated is up to 70 percent, while 83 percent of this group received the first injection.
According to the Centers for Disease Control and Prevention (CDC, acronym for English), nearly 252 million doses have been administered and, in particular, nearly 109 million have already received the full schedule in the US, which has a population of 330 million.
The North American country uses vaccines from pharmaceutical companies Moderna and Pfizer, as well as those from Johnson Johnson, although the latter is on hold for the time being to investigate possible side effects.
