This web page contains the latest national information about vaccine supplies and provides guidance to healthcare providers who are facing vaccine shortages or delays.

Note1: During 2017, large outbreaks of Hepatitis A among adults in several US cities resulted in increased demand for vaccine, resulting in constrained supplies of vaccine. In response, CDC has (1) worked directly with public health officials in affected jurisdictions to provide guidance about targeting vaccine in response to local epidemiology; (2) collaborated with manufacturers to understand options for managing supplies in the private sector and increasing national supply; (3) implemented ordering controls in the public sector; and (4) increased vaccine availability on CDC’s adult vaccine contracts.  As available vaccine supplies have increased and progress has been made  regarding ongoing outbreaks, the public sector vaccine supply strategy has evolved.  In addition, to supporting affected jurisdictions with technical assistance and vaccine supplies, additional vaccine has been made available for unaffected jurisdictions to facilitate routine vaccination activities.  Finally, while manufacturers have supply to meet current demand, CDC and vaccine manufacturers continue to monitor ongoing demand for and usage of adult Hepatitis A vaccine closely.  Of note, the constraints described in this footnote do not apply to the pediatric Hepatitis A vaccine supply in the US.  Updated Mar 2018

Pediatric hepatitis B vaccine: Merck anticipates having a limited supply of pediatric monovalent hepatitis B vaccine through mid 2020. GSK has confirmed its ability to continue to address supply gaps for pediatric hepatitis b vaccine during this period, using a combination of monovalent pediatric hepatitis B vaccine and its DTaP-HepB-IPV pediatric combination vaccine (Pediarix). The expected monovalent supply continues to provide sufficient vaccine to cover the hepatitis B birth dose for all children as well as additional pediatric hepatitis B vaccine for second and third doses. However, some adjustments will be needed from providers because of the decrease in monovalent vaccine (see attached guidance in the table above). To ensure an equitable distribution of monovalent hepatitis B vaccine and direct vaccine doses according to CDC’s clinical guidance, CDC continues to implement controlled vaccine ordering in the public sector using both Merck’s and GSK’s monovalent pediatric hepatitis B vaccines. In addition, GSK is providing monovalent doses to the private sector market directly and through their channels consistent with CDC’s clinical guidance. GSK’s DTaP-HepB-IPV pediatric combination vaccine (Pediarix) continues to be available in both the public and private sectors. Updated Sep 2019

Adult hepatitis B vaccine: With the exception of a limited release of vaccine available in the fall of 2019, Merck does not expect to be distributing adult hepatitis B vaccine or dialysis formulation during the remainder of 2019 or during 2020. Dynavax and GSK have sufficient supplies of adult hepatitis B vaccines to address the anticipated gap in Merck’s supply of adult hepatitis B vaccine during this period; however, preference for a specific presentation (i.e., vial versus syringe) may not be met uniformly during this time. Updated Sep 2019

Note3: GSK is continuing to steadily increase supply of Shingrix for the US market and anticipates producing and distributing more doses in 2020 than in 2019. Due to high levels of demand for Shingrix, GSK will continue to actively manage volume and timing of shipments to ensure distribution on a consistent and predictable schedule across customer channels. While order limits will remain in effect for the near-term, most providers can expect to see the same number or an increase in the number of doses available in 2020 and shorter wait times for delivery.

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
