Aug 12 (Reuters) - The U.S. Food and Drug Administration is
working with vaccine makers Pfizer Inc and Moderna Inc
to allow certain vulnerable people to receive a third
booster shot of their COVID-19 vaccines to improve their immune
response, the director of the U.S. Centers for Disease Control
and Prevention said on Thurdsay.
CDC Director Rochelle Walensky said that the shots would be
available to certain people who are moderately and severely
immunocompromised, such as people who have had organ transplants
and some cancer patients. She estimated the group of vulnerable
people was less than 3 percent of adults.
Walensky said the CDC's Advisory Committee on Immunization
Practices will meet on Friday to discuss this issue and offer
recommendations.
