Unvaccinated Americans were 4.5 times more likely than vaccinated people to become infected with the coronavirus, and were 10 times more likely to be hospitalized and 11 times more likely to die from it, according to one of the few studies that highlight the effectiveness of vaccines.
The study looked at more than 600,000 viruses in 13 states, representing about a quarter of the U.S. population, between April and July, and concluded that people who were not fully vaccinated were much more susceptible to infection and death from the virus.
A day after President Biden issued sweeping vaccine mandates, intended to push American workers to get vaccinated, federal health officials released the three studies that drew data from different regions of the U.S. to assess the protective power of vaccines.
The vaccine’s protection against hospitalization and death remained strong even when the Delta variant was the dominant form of infection. But the effectiveness of vaccines in preventing infection dropped from 91 percent to 78 percent, the study found.
Studies underscore a series of similar findings in recent weeks.
“As we’ve shown in study after study, vaccination works,” Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, said at a Covid briefing at the White House on Friday.
Here are some other highlights of the week:
A state judge in Washington granted a court order on Wednesday banning disruptive protests near school campuses after protests against masks at a high school in Washington’s Vancouver city resulted in a shutdown. The court order is effective as long as there are state-issued mask mandates.
Los Angeles is the first major school district in the United States to require coronavirus vaccinations for students 12 and older who attend classes in person. New York Mayor Bill de Blasio said the city, which is home to the nation’s largest school district, will not follow Los Angeles’ lead in mandating student vaccines.
Sweden prohibits all non-essential visitors from the United States. The Netherlands says vaccinated travelers must isolate themselves after arriving from the US, and unvaccinated ones aren’t welcome. These restrictions come after the European Union removed the US from a list of safe countries whose residents can travel without coronavirus testing or quarantine.
The unemployment benefits that have kept millions of Americans afloat during the pandemic expired on Monday, setting off an abrupt cut in assistance to 7.5 million people as the Delta variant shakes the recovery from the pandemic. The Biden administration is in a political fight for benefits and is now relying on other federal aid and an increase in hiring in the fall to keep vulnerable families away from foreclosures and food lines.
There have been more than 40 million cases of the coronavirus in the United States, according to a New York Times database. The total number of known infections, larger than the population of California, the nation’s most populous state, is a testament to the spread of the coronavirus, especially lately with the highly contagious Delta variant, and the United States’ efforts to control it. .
