The Centers for Disease Control and Prevention (CDC) finally admitted their “number of reported COVID-19 vaccine breakthrough cases is likely a substantial undercount.”
On May 27, 2021 the CDC acknowledges the 10,562 infections among people who are fully vaccinated against the disease have been underreported.
This is due to the data coming from VAERS, the national surveillance system that relies on passive and voluntary reporting. A large percentage of cases with “breakthrough infections” do not seek testing including those who show no symptoms.
Through April 30th, 10,262 breakthrough infections were reported from 46 U.S. states and territories to the CDC. These high rates of known cases prompted the CDC to stop counting breakthrough infections as of May 1, except for those that cause hospitalization or death.
Breakthrough cases are those appearing two or more weeks after a person’s vaccine final shot. That’s primarily the second Pfizer or Moderna dose, but can be the single-shot Johnson & Johnson.
Of the cases released by CDC, more than six in 10 occurred in females. The median patient age is 58.
Approximately 10 percent of the patients required hospital care two weeks or more after their last jab, and 160, or about 1.5 percent of them died. This does not include those who died within two weeks.
Sequencing data were available for only 555 of the breakthrough cases. The CDC admitted sequence data are only available for a small proportion of the cases that were reported–and those are acknowledged are drastically underreported.
Dr. Ashish Jha, dean of the Brown University School of Public Health, said the report indicates that the three vaccines authorized for emergency use in the United States are “not 100 percent. Nothing in life is 100 percent. So, yeah, we’re going to see some breakthrough infections…” he told ABC News.
