"The study found that the vaccine reduced the risk of emergency department visits and hospitalizations among healthy adults by about half last winter."
"A covid vaccine study that the CDC’s chief halted this spring over methodological concerns was published Tuesday in JAMA Network Open, a leading peer-reviewed medical journal.
The analysis used the same methodology that CDC’s interim director had criticized when the paper was not allowed to be published in the weekly scientific report of the Centers for Disease Control and Prevention.
The study, which had been slated for publication in March in the CDC’s Morbidity and Mortality Weekly Report, found that the covid-19 vaccine reduced the risk of emergency department visits and hospitalizations among healthy adults by about half last winter. The findings were consistent with what researchers have found in past years, that the vaccine can help reduce the risk of severe illness in adults even after accounting for immunity from prior vaccination or infection."
