1Sanofi Pasteur has decided to discontinue production and distribution of Diphtheria and Tetanus Toxoids Adsorbed® (DT) and is withdrawing its licenses in all countries. The last lot was manufactured in October 2020 with an expiry date of April 2023. Sanofi expects to exhaust available supply by the end of 2022.2Supply of Sanofi’s Flublok vaccine for the 2023-24 season is reduced from the original supply plan. Impacted customers have been or are being contacted by the manufacturer and offered doses of Fluzone QIV influenza vaccine or Fluzone High Dose influenza vaccine.  The manufacturer has reported that there are sufficient supplies of both of these vaccines available to address the reduction in the supply of Flublok for the 2023-24 season.3In the context of a limited supply of nirsevimab during the 2023-2024 RSV season, CDC initially recommended prioritizing available 100mg doses. Given the recent increase in supply of nirsevimab, CDC advises providers to immunize infants as quickly as possible in accordance with ACIP recommendations rather than reserving doses for infants born later in the RSV season. Although the supply of nirsevimab has increased, available supply may continue to vary locally and by healthcare facility. Providers who continue to have limited supply should prioritize nirsevimab to protect infants at the highest risk for severe RSV disease
Why are there vaccine shortages?
In the United States shortages of many vaccines in the recommended childhood immunization schedule occurred in the past. Some of these shortages were widespread while others were localized. Reasons for these shortages were multi-factorial and included companies leaving the vaccine market, manufacturing or production problems, and insufficient stockpiles. Consequently, some shortages were only specific to one manufacturer.
Shortages of several of these vaccines necessitated temporary changes in recommendations for their use. During that period, summary information about the shortages including projected duration and recommendations for temporary changes in the childhood immunization schedule were provided.
Who can I contact to answer my questions?
Questions including those dealing with changes in child care and school requirements necessitated by vaccine supply problems when they occur can be answered by State Health Department immunization programs.
General immunization questions can be answered by**The CDC Contact Center at 1-800-CDC-INFO
