She is experiencing mild symptoms and is up to date with her vaccines.

In a September statement, Walensky said that boosters would provide broad protection against sublineages.
"The updated COVID-19 boosters are formulated to better protect against the most recently circulating COVID-19 variant. They can help restore protection that has waned since previous vaccination and were designed to provide broader protection against newer variants," she said.
