The Centers for Disease Control and Prevention (CDC) announced on Monday that Covid vaccines are less effective at preventing hospitalizations, especially in people over 75.
The Delta variant is being blamed for the vaccine’s decreased effectiveness.
The COVID-19 vaccines’ ability to keep people out of the hospital appears to be dropping slightly, particularly for those 75 and older, the Centers for Disease Control and Prevention announced Monday during an advisory panel.
The CDC has previously estimated that 97% of people in the hospital being treated for COVID-19 are unvaccinated, but that data was collected before the spread of delta, a hyper-transmissible variant that many doctors have warned appears to be making people sicker.
The latest CDC analysis estimates that the ability of the COVID vaccines to keep a person out of the hospital is now between 75% to 95%.
For people older than 75 in particular, vaccine effectiveness against hospitalization experienced the steepest decline, from more than 90% to 80% between June and July.
The CDC made this announcement 11 days after its director stated that people who received the Covid vaccine early in their lives are at a higher risk of developing severe disease.
“We are seeing concerning evidence of waning vaccine effectiveness over time and against the Delta variant,” Walensky said a couple weeks ago.
Walensky continued, “Reports from our international colleagues, including Israel, suggest increased risk of SEVERE disease amongst those vaccinated early.”
Joe Biden is in discussions with Fauci for a Covid booster every 5 months.
COVID-19 vaccines 66% effective against Delta variant
Vaccine effectiveness against COVID-19 infection dropped from about 91% to 66% once the Delta variant became the dominant strain in the U.S., according to a new study published Tuesday by the CDC.

During December 14, 2020–August 14, 2021, full vaccination with COVID-19 vaccines was 80% effective in preventing RT-PCR–confirmed SARS-CoV-2 infection among frontline workers, further affirming the highly protective benefit of full vaccination up to and through the most recent summer U.S. COVID-19 pandemic waves. The VE point estimates declined from 91% before predominance of the SARS-CoV-2 Delta variant to 66% since the SARS-CoV-2 Delta variant became predominant at the HEROES-RECOVER cohort study sites
