The U.S. Food and Drug Administration (FDA), Centers for Disease Control and Prevention (CDC) and Western States Scientific Safety Review Workgroup have all recommended an additional dose of mRNA COVID-19 vaccine be administered to people with moderately to severely compromised immune systems. “This official CDC recommendation — which follows FDA’s decision to amend the emergency use authorizations of the vaccines — is an important step in ensuring everyone, including those most vulnerable to COVID-19, can get as much protection as possible from COVID-19 vaccination,” said CDC Director Rochelle P. Walensky, MD, MPH in an Aug. 13 media statement. You can read more about the recommendation on the Oregon Vaccine News blog.
