The United States Centers for Disease Control and Prevention (CDC) has shown more evidence that people who have not been vaccinated are more likely to be infected with COVID-19 and 11 times more likely than those who have been vaccinated.
At the White House COVID-19 meeting on Friday, CDC President Dr Rochelle Walensky said this shows that “the vaccine works and will protect us from the serious problems of COVID-19”.
The study also covered more than 600,000 cases of COVID-19, hospital admissions and deaths in 13 countries, and major cities from April to mid-July.
“Looking at the cases in the past two months when the difference between the Delta was very common in the country, those who did not receive the vaccine had four and a half times more likely to take COVID-19, three times as likely to be hospitalized, and died of the disease 11 times. “Walensky said.
While the defense remains strong against it Delta, the study also confirmed the increase in COVID-19 infections among people with complete immunization, whose authors indicated a “rapid decline in adequate immunodeficiency vaccine”.
A second U.S. study also found that the COVID-19 vaccine provides strong protection against hospitalization and death, even in the face of a variety of Delta strains, but vaccine safety appears to be declining among older adults, especially those over 75 or older.
The U.S. medical data from nine countries at a time when the Delta gap was large also states that the Moderna vaccine was more effective in preventing exposure to people of all ages than the Pfizer or Johnson & Johnson vaccine.
In a study of more than 32,000 visits to emergency care hospitals, emergency rooms and hospitals, the Moderna vaccine was 95% effective in preventing hospitalization compared to 80% of Pfizer and 60% of J&J.
One study looked specifically at how mRNA vaccines work – such as shooting from Pfizer and Moderna – in patients at five Veterans Affairs clinics, a multidisciplinary group made up mainly of older men with advanced disease.
Of the more than 1,000 COVID-19 hospitals in the study, researchers found that both vaccines had an 86.8 percent effective anti-hospital vaccine – even against another type of Delta. But the effective vaccine dropped to 79.8 percent among those 65 years of age or older.
In the third study, which looks at clinical trials in nine countries, the total effectiveness of the vaccine remained 86% against the hospital and 82% against going to the emergency room or emergency room. However, clinical vaccination was “very low” in adults 75 years of age or older, falling by 76 percent – the first time a drop had been shown in these cases.
More comes a day after US President Joe Biden revealed a six-part plan Fighting the epidemic, which includes practices such as asking employers to force vaccinations or forced labor, in order to get home-based reading exams and to develop a free trial program for the government.
“I don’t know of any scientist out here who doesn’t think it makes sense to do the six things I’ve said,” Biden said Friday on his way to a local school in Washington, DC.
“We have to come together. And I think most people – look at elections – most Americans know we should do these things. It’s hard, but important. We will do this, ”he said.
According to CDC figures, Americans are about 177.4 million, or 53.4 percent of all U.S. citizens, they have been fully vaccinated so far.
On average, more than 136,000 are present every day, according to CDC, inside a significant increase from early summer when disease had declined sharply across the country. More than 1,000 people die every day from the disease.
