The day after President Biden issued an extensive vaccine order aimed at promoting coronavirus vaccination to American workers, federal health officials said shots were effective in preventing infection, hospitalization, and death. We have published several studies that emphasize this. Delta variant was dominant..
Three studies, drawing data from different parts of the United States, evaluated the defenses of vaccines. Between April and July, we examined more than 600,000 viral cases in 13 states, about a quarter of the U.S. population, and unvaccinated individuals were far more affected by viral infections and deaths. I concluded that it was easy to receive.
they There was a 4.5 times chance Studies have shown that they are 10 times more likely to be infected, 10 times more likely to be hospitalized, and 11 times more likely to die of the coronavirus than vaccinated individuals.
Vaccine protection against hospitalization and death remained strong, even when the delta mutant was the predominant form of infection. However, studies have shown that the effectiveness of vaccines in infection prevention has declined from 91 percent to 78 percent.
These studies highlight a series of similar findings over the last few weeks.
At the White House Covid Briefing on Friday, Dr. Rochelle Warrensky, director of the US Centers for Disease Control and Prevention, said:
As more and more Americans were vaccinated, experts always predicted that immunized people would make up a larger proportion of inpatients. “I would like to reiterate here that unvaccinated far more than 90 percent of the people in the hospital,” said Dr. Walensky.
“There are still more than 10 times more people who are not vaccinated than those who are vaccinated,” she added.
Two other studies published on Friday found weakened vaccine protection among older people.
In one study conducted at five veterans’ medical centers, Protection against hospitalization declines with age, It decreased to 80% of people over 66 years old and 95% of adults aged 18 to 64 years. The second study found that the effectiveness of the vaccine diminished at age 75 years.
The findings may help identify populations that may require additional doses or booster shots. In August, the Food and Drug Administration approved Pfizer-BioNTech and Moderna coronavirus vaccines give some people a third dose Immune system, including organ transplant patients, is weakened.
However, authorities say there is insufficient data on whether the effectiveness of the vaccine declines over time to recommend booster immunity in healthy adults.
The data also suggest that the Moderna vaccine may be slightly more effective in preventing infection and hospitalization with the Delta variant compared to the Pfizer-BioNTech vaccine. Although both mRNA vaccines showed higher efficacy rates than Johnson & Johnson Shot, these studies were not originally designed to evaluate the efficacy comparison of different vaccinations.
With 33,000 studies Medical encounters in 9 states Between June and August, the Moderna vaccine was 92% effective against infection, while the Pfizer-BioNTech shot was 77% effective.
