ALBANY, N.Y. (NEWS10)- COVID vaccines remain highly effective at keeping people out of the hospital despite breakthrough infections, according to an analysis from the New York State Department of Health (DOH).
The analysis, published by the Centers for Disease Control and Prevention (CDC), determined overall effectiveness of the vaccines dropped from about 92% to 80%. However, 95% of people with breakthrough cases did not have to be hospitalized.
“The findings of our research are clear: Vaccines provide the strongest protection for New Yorkers against getting infected or becoming hospitalized due to COVID-19,” said State Health Commissioner, Dr. Howard Zucker, a senior author of the analysis.
The DOH tracked breakthrough cases after the Delta variant surfaced from May 3 to July 25. They looked at the rate of cases as well as hospitalization among vaccinated New Yorkers who were 18 years or older.
The analysis also determined that unvaccinated New Yorkers were eight times more likely to be diagnosed with COVID and 11 times more likely to be hospitalized, compared to vaccinated New Yorkers.
“At this important time in the epidemic, we’ve observed a clear increase in cases for unvaccinated and even vaccinated people. Yet these results demonstrate that compared to unvaccinated people, those who are vaccinated remain consistently far more protected against infection and hospitalization,” DOH’s Dr. Eli Rosenberg and lead author of the analysis said.
The analysis will be published Wednesday in the CDC’s Morbidity and Mortality Weekly Report series. The full analysis is also available below.
