Advisers to the U.S. Centers for Disease Control and Prevention on Thursday will consider evidence suggesting that a booster dose of COVID-19 vaccines could increase protection among people with compromised immune systems.
Data presented ahead of the meeting noted that such people have a reduced antibody response following the recommended primary vaccination series compared with healthy individuals.
"Emerging data suggest that an additional COVID-19 vaccine dose in immunocompromised people enhances antibody response and increases the proportion who respond," slides released ahead of the meeting showed.
The committee is not scheduled to vote on a recommendation for whether to administer additional doses. That could be decided at a later meeting.
