In the last few weeks, the FDA has started to limit COVID vaccine approvals, limiting their use in healthy people under 65 years of age, and HHS Secretary Robert F. Kennedy Jr. appeared to unilaterally take down CDC guidance that recommended their use in pregnant women and healthy children.

A medical officer at the US Centers for Disease Control and Prevention who was working on the committee that was weighing changes to the agency’s Covid-19 vaccine recommendations resigned on Friday, the same day officials the US Department of Health and Human Services announced they had removed the CDC recommendation for pregnant women and healthy children to get Covid-19 vaccines.

Lakshmi Panagiotakopoulos said she could no longer help vulnerable people after officials removed recommendations to immunize children and pregnant women.
