WASHINGTON — The U.S. Senate voted to confirm Susan Monarez as director of the Centers for Disease Control and Prevention

on Tuesday.

Monarez — whom the Senate confirmed on a party-line vote, 51-47 — will now be responsible for the national public health agency within the Department of Health and Human Services. The Atlanta-based agency has faced backlash as HHS Secretary Robert F. Kennedy Jr. pursues a vaccine-skeptical agenda.

GOP Sens. Bill Hagerty of Tennessee and Dan Sullivan of Alaska did not vote.

Monarez was the acting director of the CDC between January and March. She previously served as the deputy director of the Advanced Research Projects Agency for Health, which is part of HHS.

Monarez, who has a Ph.D. in microbiology and immunology, will be the first person without a medical degree to hold the title since 1953.

The White House originally selected former Florida U.S. Rep. Dave Weldon to lead the CDC but withdrew the nomination in March.

Monarez’s confirmation followed a procedural vote earlier Tuesday that saw her advance, 52-47, along party lines.

Kennedy continues to face scrutiny after he fired all 17 members of the Advisory Committee on Immunization Practices, or ACIP, in June and named eight new members — a number of whom are viewed as skeptical of vaccines.

Vermont independent Sen. Bernie Sanders, ranking member of the Senate Committee on Health, Education, Labor and Pensions, launched an investigation alongside seven Democratic members of the committee Tuesday regarding Kennedy’s firings and replacements within the critical vaccine panel.

“By removing all 17 of ACIP’s members and replacing them with eight individuals handpicked to advance your anti-vaccine agenda, you have put decades of non-partisan, science-backed work — and, as a result, Americans’ lives — at risk,” the senators wrote in a letter to Kennedy.

Those seven Democratic committee members include Sens. John Hickenlooper of Colorado, Lisa Blunt Rochester of Delaware, Angela Alsobrooks of Maryland, Ed Markey of Massachusetts, Maggie Hassan of New Hampshire, Andy Kim of New Jersey and Tim Kaine of Virginia.
