Hib vaccine currently is not available from Wyeth. Updates on their supply of this product are not available.


Production of Varicella Zoster Virus (VZV) bulk has been temporarily suspended due to low yields. VZV bulk is used to manufacture varicella vaccine, MMR-V vaccine, and zoster vaccine. It is projected that stocks of ProQuad® (MMR-V) will be depleted in the July 2007 timeframe. Current projections are for adequate supply to fully implement the recommended immunization schedule for varicella vaccine for all age groups and for the recommended use of zoster vaccine. Updates will be provided when available. ADDED May 10

Why were 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.
