CDC reports shortages of H1N1, seasonal influenza vaccine

Agency is hopeful that both vaccines will be widely available by late 2009.

At a recent CDC Advisory Committee on Immunization Practices (ACIP) meeting, the agency expressed dissatisfaction with the current available supply of H1N1 and seasonal influenza vaccine but expects increased supplies by early November and widespread availability of both vaccines by late 2009. About 28 million doses of H1N1 vaccine are expected to be available by the end of October—12 million less than the projected total of 40 million doses. CDC remains hopeful that 43 million doses of H1N1 vaccine will be available by early November. Current H1N1 vaccine supply totals are available at the CDC website, 2009 H1N1 influenza vaccine supply status

CDC noted that the delay in widespread availability of H1N1 vaccine is a worldwide problem and that production of H1N1 vaccine supply is pushing the limits of current influenza vaccine manufacturing capabilities.

In addition to the slower-than-expected release of H1N1 influenza vaccine, a shortage of seasonal influenza vaccine exists. As of October 16, 85 million doses of seasonal influenza vaccine had been distributed (~74% of doses expected this season). Between 114 and 115 million doses of seasonal influenza vaccine are expected. The limited supply coupled with an increased public demand has made the situation more acute.

The agency has contracted for 251 million doses of H1N1 bulk vaccine. A total of 117 million doses have been contracted to fill into vials, syringes, and sprayers, while additional doses may be filled for delivery by the end of 2009 as needed.

CDC is using a centralized distribution process for H1N1 influenza vaccine; all H1N1 vaccine is allocated among states pro rata as it becomes available. States are receiving daily updates and placing orders against their allocation, then CDC is verifying the orders, transmitting them to the distributor (McKesson Specialty Pharmaceuticals), and the distributor is filling and shipping the orders. The number of distribution points now total 150,000 (versus the original 90,000), and H1N1 vaccine orders placed on Monday, for example, are being shipped on Tuesday and arriving on Wednesday.

Questions about your H1N1 vaccine order?

State health departments are coordinating all vaccine orders; therefore, any questions about order entry, shipping timelines, or delivery status should be directed to your local/state health department contact for the H1N1 immunization program. (Health department information can be found here.) State health departments are placing orders on providers’ behalf and managing product allocations. Provider questions or concerns about temperature monitors in packages received can be directed to McKesson’s Specialty Vaccine Program customer service line (877-836-7123).
