Note1: Sanofi Pasteur resumed shipping of their pertussis-containing vaccines, Daptacel (DTaP), Pentacel (DTaP-IPV-Hib) and Adacel (Tdap), in mid-October of 2013. While product availability continues to increase, supply will remain constrained over the next several months as inventories rebuild. GlaxoSmithKline has taken steps to meet increased demand for pertussis-containing vaccines and anticipates being able to address gaps related to these supply limitations, using a combination of products and presentations. Of note, during this time period, due to significant increases in demand for Boostrix (Tdap), GSK has put in place controls to help manage inventory to maintain continued supply to the marketplace. Therefore, backorder and delays in deliveries may occur, but are expected to be short in duration. Also, provider preference for vaccine presentation (syringes/vials) may not be able to be accommodated at times during this period. Updated Mar 17, 2014
Note2: Based on input from the ACIP, professional societies, scientific leaders, and customers on October 26, 2009 Merck announced the company has decided not to resume production of ATTENUVAX® (Measles Virus Vaccine Live), MUMPSVAX® (Mumps Virus Vaccine Live), and MERUVAX®II (Rubella Virus Vaccine Live). This science-based decision will support vaccination of the largest group of appropriate individuals. Updated January 27, 2010
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.
