During a portion of an interview with CBS News on Wednesday aired on Thursday's "CBS This Morning," CDC Director Dr. Rochelle Walensky responded to criticisms of the agency's monkeypox response by saying CDC officials "still have not seen all the immunization data that we need to be able to see in order to mobilize vaccinations" and this is "similar to some of the challenges that we had with COVID-19," where officials didn't have all the data they needed.
