The health and human services secretary and noted vaccine skeptic named a new panel to provide the guidance often used by states in setting school immunization requirements.

All 17 experts from the Advisory Committee for Immunization Practices who were replaced last month by Robert F. Kennedy Jr. called the health secretary's new picks "inexperienced and biased."

The members of the CDC vaccine advisory committee HHS Secretary Robert F. Kennedy Jr. removed say the panel has “lost credibility.”
