The study published on the cdc.gov website:
Risk Factors for Severe COVID-19 Outcomes Among Persons Aged ≥18 Years Who Completed a Primary COVID-19 Vaccination Series — 465 Health Care Facilities, United States, December 2020–October 2021
says the following:
Among 1,228,664 persons who completed primary vaccination during December 2020–October 2021, severe COVID-19–associated outcomes (0.015%) or death (0.0033%) were rare. Risk factors for severe outcomes included age ≥65 years, immunosuppressed, and six other underlying conditions. All persons with severe outcomes had at least one risk factor; 78% of persons who died had at least four.MMWR Morb Mortal Wkly Rep 2022;71:19–25. DOI:
So, if I’m reading this correctly, there were ZERO severe COVID-19 associated outcomes for fully vaccinated people with no risk factors (mostly before delta, mostly before boosters). Zero! Isn’t this a huge deal? Shouldn’t this be headlining newspapers? I don’t understand why it’s not in the news. And now with Omicron (milder infection) and boosters (better protection), current protection should be even better.
In this study, a severe COVID-19 outcomes is defined as:
– Diagnosis of acute respiratory failure
– Need for non-invasive ventilation (a tight fitting oxygen mask)
– ICU admission
Interestingly, tracheal intubation isn’t listed here, but I guess that’s associated with the ICU.
