(CNN) – Pfizer / BioNTech and Moderna vaccines were found to be 94% effective against hospitalization for COVID-19 among adults 65 years of age or older. Fully vaccinate it, according to A new study from the Centers for Disease Control and Prevention (CDC) de EE.UU.The study also found that the vaccines were 64% effective among partially vaccinated older adults, meaning that they had only received one dose of the vaccine so far.
the findings Match the results From clinical trials of vaccines. These results showed an efficacy of between 94% and 95%, noted researchers from the Centers for Disease Control and Prevention and other institutions.
“This data indicates that continuing to rapidly vaccinate American adults against COVID-19 will likely have a significant impact on hospitalization with COVID-19 and could lead to a commensurate reduction in COVID-19 disease and deaths,” the researchers wrote in your study.
The study included data from 417 adults aged 65 or over with symptoms similar to COVID-19 who were admitted to 24 hospitals in 14 states. Admission took place between January 1 and March 26. Of these patients, 187 patients tested positive for coronavirus and 230 had tested negative.
The researchers found that among those who tested positive, most had not been vaccinated. Only 18 of the patients were vaccinated, or 10%, partially with the first dose of the Pfizer or Moderna vaccine. Only one person was vaccinated with 0.5%.
Of the 230 adults who tested negative, 44 were partially vaccinated, or 19%. On the other hand, 18 adults, or 8%, were fully vaccinated, according to the data.
Overall, “these results are encouraging and good news for the two-thirds of people over the age of 65 who have already been fully vaccinated,” Dr. Rochelle Wallinski said, The director of the CDC in a press release Wednesday.
“Covid-19 vaccines are very effective, and these realistic results confirm the benefits seen in clinical trials, preventing hospitalizations among the most vulnerable,” Wallinski said. “The results are promising for our communities and our hospitals. As our vaccination efforts continue to expand, COVID-19 patients will not overwhelm healthcare systems, leaving hospital staff, family, and services available for people in need of other medical conditions.
The new study included data from California, Colorado, Maryland, Massachusetts, Michigan, Minnesota, New York, North Carolina, Ohio, Oregon, Pennsylvania, Tennessee, Texas, and Utah. More research is needed to determine whether similar results are obtained in more states to fully represent the American population.
Similar results have been found previously.
In another study Posted last week on New England Journal of Medicine Of 417 NYU Rockefeller employees who were fully vaccinated with Pfizer or Moderna vaccines, only two were found, also about 0.5%, after testing positive for COVID-19.
In March, drug companies Pfizer and BioNTech announced a real-world test by the Israeli Ministry of Health Turns out That the number of COVID-19 cases and deaths among fully vaccinated people has decreased “dramatically”.
This analysis determined that the vaccine was 94% effective in preventing asymptomatic COVID-19. This means an infection that has no symptoms.
