The U.S. Centers for Disease Control and Prevention (CDC) recently announced approximately 75% of children had serologic evidence of previous infection with the SARS-CoV-2 coronavirus as of February 2022.

Furthermore, approximately one-third of these children became newly seropositive for the virus since December 2021.

And during December 2021–February 2022, the overall U.S. population seroprevalence increased from 33.5% (95% CI = 33.1–34.0) to 57.7% (95% CI = 57.1–58.3), as of April 26, 2022.

The national commercial laboratory seroprevalence study is a repeated, cross-sectional, nationwide survey that estimates the proportion of the population in 50 U.S. states, the District of Columbia, and Puerto Rico with infection-induced antibodies to SARS-CoV-2.

Additionally, the CDC says 'COVID-19 vaccination following a SARS-CoV-2 infection provides additional protection against severe disease and hospitalization.'

The estimated mRNA COVID-19 vaccine effectiveness against reinfection leading to hospitalization during the Omicron-predominant period was approximately 35% after dose 2 and 68% after a booster 3rd dose.
