The Centers for Disease Control and Prevention (CDC) vaccine advisory group has long had a work group in place to review the latest COVID-19 vaccine science, including weighing the risks and benefits, but a newly constituted group will launch a sweeping new review of the vaccines led by a member who has opposed COVID vaccines.

The Brownstone Institute on August 22 reported that Retsef Levi, PhD, one of seven members appointed to the Advisory Committee on Immunization Practices (ACIP) by US Health and Human Services (HHS) Secretary Robert F. Kennedy Jr., has been appointed to lead the COVID vaccine review. On August 20, the CDC posted updated terms of reference for the COVID vaccine work group, which is lengthy. Some of the topics include impacts from repeated boosting and mapping policies in other countries.

Levi does not have a biomedical degree or clinical medicine experience. He has a doctorate in operations research and is a professor of operations management at MIT Sloan School of Management. On social media, Levi has called mRNA vaccines dangerous and said they should be removed from the market.
