Note1: In February 2009, both Merck and GSK experienced an inability to fill orders for pediatric Hepatitis B vaccine, resulting in backorders. CDC has released doses from its monovalent pediatric Hepatitis B vaccine stockpiles to each manufacturer to support private and public sector vaccine usage through March. Merck expects supplies of pediatric Recombivax HB® to be limited during the remainder of 2009 and does not expect to return to a full supply until some time in 2010. GSK expects to be able to meet the US market demand for monovalent Hepatitis B vaccine through the end of May with its pediatric Hepatitis B vaccine (Pediatric Engerix-B®), and is working closely with CDC to determine how much additional monovalent Hepatitis B product can be supplied to the US market during the second half of 2009. March 2, 2009
Note2: In December 2008, Merck communicated with CDC that it expected to deplete available adult and dialysis formulations of their hepatitis B vaccine, Recombivax HB® in the first quarter of 2009. Once depleted, these formulations will be unavailable for the remainder of 2009. Supply of GSK's Adult hepatitis B vaccine (Adult Engerix-B®) and Adult hepatitis A/hepatitis B combination vaccine (Twinrix®) is sufficient to meet demand for routine adult usage of this vaccine as well as CDC's ongoing High Risk Adult Hepatitis B Initiative. Updated March 2, 2009
Note3: Merck is working to restore market availability of Hib-containing vaccines, PedvaxHIB® and Comvax®, but the availability of these vaccines may be subject to a further delay, with Merck's current estimate of availability being mid to late 2009. In response to the shortage, CDC and AAP recommend deferral of the booster dose at 12 through 15 months of age except in high risk groups. Sanofi pasteur currently is providing sufficient Hib vaccine ActHIB® and Pentacel) to cover the 3 dose series through mid 2009, and has developed a supply plan to support reinstatement of the booster dose some time in mid 2009, using a combination of their Hib-containing products. CDC will work closely with sanofi pasteur to determine available supply and options for catch up. Updated March 2, 2009
Note4: In December 2008, Merck communicated with CDC that it was not producing or taking orders for the monovalent vaccines ATTENUVAX® (measles vaccine), MUMPSVAX® (mumps vaccine) and MERUVAX® (rubella vaccine). Merck has not yet made a decision about the future availability of these three monovalent vaccines. Updated March 2, 2009
Note5: There is adequate supply of Varivax® (varicella vaccine) to fully implement the recommended 2-dose immunization schedule, including catch-up, for all age groups. ProQuad® (MMRV) will not be available in 2009. Zostavax® (zoster vaccine) is available for ordering; however, the manufacturer is experiencing shipping delays. Merck anticipates a return to normal shipping times for Zostavax® in mid-2009. Merck vaccine supply status including specific shipping status information for zoster vaccine is updated weekly and may be found at www.merckvaccines.com . Updated March 2, 2009
Note6: Merck & Co previously had experienced production delays that resulted in temporarily not accepting orders for Pediatric and Adult hepatitis A vaccines (Pediatric & Adult VAQTA®). As of December 1, 2008, Merck's Pediatric/Adolescent formulation of hepatitis A vaccine, VAQTA®, is available for ordering. Merck estimates that the Adult formulation of VAQTA® may be available in the second quarter 2009. GSK production and supply of their Pediatric and Adult hepatitis A vaccine (Pediatric & Adult Havrix®) and their Adult hepatitis A/hepatitis B combination vaccine (Twinrix®) are in adequate supply to meet demand. Updated March 2, 2009
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.
