The Centers for Disease Control and Prevention (CDC) reported more than 10,000 post-vaccination COVID-19 cases. These so-called breakthrough cases came from 46 U.S. states and territories that sent figures to the public health agency. The CDC’s report came as about 101 million Americans became fully vaccinated as of April 30.

According to CDC data as of April 30, there were 10,262 breakthrough infections reported in fully vaccinated people. Breakthrough cases are defined as Wuhan coronavirus infections that occur two or more weeks after someone gets their final COVID-19 vaccine dose. This can refer to the second dose of the Pfizer/BioNTech or Moderna mRNA vaccine or the single-dose Johnson & Johnson vaccine.

Approximately 10 percent of the 10,262 patients required hospital care. About 1.5 percent – equal to 160 persons – died of COVID-19. Meanwhile, about three in 10 hospitalized patients did not show symptoms or were admitted for a reason unrelated to COVID-19.
