Oklahoma Immunization Update May 2012 PREVENTION and PREPAREDNESS SERVICES IMMUNIZATION SERVICE PLEASE POST & DISTRIBUTE TO ALL NURSING AND MEDICAL STAFF Reduced Supply of Pentacel Sanofi Pasteur announced that effective April 20 it will temporarily implement order limitations for its DTaP-IPV/ Hib vaccine (Pentacel®) for Vaccines for Children (VFC) and private orders. Orders for Sanofi Pasteur’s DTaP vaccine (Daptacel®) will be limited for private orders, but not for VFC orders. As a result, beginning Monday April 23, 2012, the supply of Pentacel for the VFC program and for private purchase will be allocated among all states and private providers. Allocations of Pentacel are necessary because of a manufacturing delay that will temporarily reduce supply below the level needed to fully satisfy market demand. This reduction in supply is anticipated to last throughout the summer. Sanofi Pasteur reports this is solely a manufacturing delay issue and it is not a safety or quality issue. IMPORTANT: No child should go unvaccinated because of this supply issue. Ample vaccines in other presentations are available and must be used to avoid missed opportunities to vaccinate. The Immunization Service will review all VFC orders for Pentacel and will ensure that all providers have an adequate supply of DTaP, IPV, and Hib vaccines to immunize all children on time. Hiberix No Longer Available Hiberix®, manufactured by GlaxoSmithKline will not be produced for the foreseeable future. It was introduced to the U.S. market to fulfill a need for Hib vaccine due to the Hib vaccine shortage of 2008 and 2009 which has been resolved. Vaccine Safety Datalink Project & Rapid Cycle Analysis The Vaccine Safety Datalink (VSD) project is a collaborative effort between the Centers for Disease Control and Prevention (CDC) and ten large managed care organizations. The project was established in 1990 to monitor immunization safety. The VSD project includes a large linked database that uses administrative data sources at each managed care organization. Each participating site gathers data on vaccination (vaccine type, date of vaccination, concurrent vaccinations), medical outcomes (outpatient visits, inpatient visits, urgent care visits), birth data, and census data. In 2005, the VSD project team launched an active surveillance system called Rapid Cycle Analysis (RCA). Rapid Cycle Analysis monitors adverse events following vaccination (possible side effects) in near real time, so the public can be informed quickly of possible risks. RCA data come from the participating managed care organizations that include more than 8.8 million people annually, representing nearly 3% of the U.S. population. The RCA data contain no personal identifiers and the data is updated every week. Each week, the rates of adverse events that occur in people who have received a particular vaccine are compared to the rates of adverse events that occur in a similar group of people who have not received that vaccine. If the rate of adverse events among vaccinated people is significantly higher than among the comparison group, the vaccine may be associated with an adverse event. VSD project scientists then conduct a formal epidemiological study to determine if there is a true association of an increased risk of the observed adverse event with the receipt of a particular vaccine. Rapid Cycle Analysis is used to monitor the safety of all newly licensed vaccines, including meningococcal conjugate vaccine, rotavirus vaccine, MMRV vaccine, Tdap vaccine, and HPV vaccine. The obtained data is then incorporated into the recommendations for use of new vaccines. Rapid Cycle Analysis should provide reassurance to parents that vaccine safety is being monitored on a continual basis. New Oklahoma State Immunization Information System (OSIIS) Coming in 2013 A new and significantly improved version of Oklahoma’s State Immunization Information System (OSIIS) is scheduled to begin operating on February 1, 2013. Missed Opportunities Contribute to Measles Cases In a presentation on the epidemiology of measles for the Advisory Committee on Immunization Practices (ACIP) on October 26, 2011, Huong McLean, PhD, MPH, reported that of the 241 people who had measles from 2008 through 2011 in the United States, 195 (81%) were 19 years of age or younger and 34 (17%) of those children had not received measles vaccine due to a missed opportunity. A missed opportunity for vaccination is defined as a healthcare encounter in which a person is eligible to receive a vaccination but is not vaccinated completely.
