These so-called breakthrough infections occurred among people of all ages. Just over 40% were in people age 60 or older, and 65% occurred in women. Twenty-nine percent of infected people reported no symptoms, but 7% were hospitalized and just over 1%, 74 people, died, according to the CDC.
Public health officials have said breakthrough infections were expected, since manufacturers have warned loudly and often that the vaccines are not 100% protective. The Pfizer and Moderna versions have consistently been shown to be above 90% effective, most recently for at least six months. Studies have also shown they are nearly 100% effective at ensuring that the small fraction of vaccinated patients who do contract the virus will not get severe cases or require hospitalization.
