95.8 million vaccinated
A person is considered fully vaccinated two weeks after the vaccine was injected (second dose for those who received two vaccines).
This applies to at least 95.8 million people in the United States, or nearly 30% of the population, who have received the required dose of one of three nationally approved vaccines (Pfizer / BioNtech, Moderna, or Johnson & Johnson).
Health authorities have updated their recommendations based on the new announcements.
In the United States, restrictions vary by state, and some have strict regulations requiring masks to be worn anywhere outside the home, even without anyone nearby. Now, these states must change these commitments, even if they are not absolutely binding to do so.
This is, for example, the case of Massachusetts, where the governor announced on Tuesday that he would lift the obligation to wear a mask outdoors when physical distancing is possible.
Health authorities began recommending that all Americans, that is, including those who were not sick, wear masks since the beginning of April 2020, that is, a little over a year ago.
Wearing a mask quickly became a highly politicized issue in the United States, where conservatives under the leadership of Donald Trump viewed it as an affront to their personal freedom. Progressive people generally believe that the mask is also a way to show that they are serious about the virus and their solidarity during a crisis.
It is now widely believed that transmission of COVID-19 occurs primarily through the air, not only through droplets released when coughing or sneezing, but also through small particles that remain suspended in the air. Air that can be released simply by talking or even breathing. …
For this reason, it is more risky to be in a room inside than outside, because in this case the air remains trapped, especially when it is not ventilated.
Several studies have supported this idea, showing that the vast majority of infection occurs through indoor contact with an infected person.
