Current Suspected Overdose Deaths in Delaware for 2017: 227
The Delaware Division of Public Health (DPH) is forwarding this Health Alert from the Centers for Disease Control and Prevention (CDC).
FDA is updating its recommendations on both Rotarix and RotaTeq, vaccines for the prevention of rotavirus disease in infants. Based on careful evaluation of a variety of scientific information, FDA has determined it is appropriate for clinicians and health care professionals to resume the use of Rotarix and to continue the use of RotaTeq.
On March 22, 2010, FDA provided an early communication regarding Rotarix, manufactured by GlaxoSmithKline Biologicals (GSK). At that time, FDA recommended that clinicians and public health professionals in the United States temporarily suspend the use of Rotarix while the agency and manufacturer investigated the finding of DNA from porcine circovirus type 1 (PCV1) in the vaccine. Since that time, both FDA and GSK have confirmed the presence of PCV1 in the vaccine. On May 6, 2010, FDA provided information about RotaTeq, manufactured by Merck & Co, Inc. FDA indicated that preliminary studies conducted by Merck identified fragments of DNA from PCV1 and from a related porcine circovirus type 2 (PCV2) in RotaTeq. FDA noted that it would seek input from its Vaccines and Related Biological Products Advisory Committee (VRBPAC) and provide updates in the near future.
FDA has evaluated laboratory results from the manufacturers and its own laboratories. In addition, FDA’s VRBPAC convened on May 7, 2010 to discuss the findings of PCV and PCV DNA in rotavirus vaccines. Based on a careful evaluation of this information, a thorough review of the scientific literature, and input from scientific and public health experts, the Agency is revising its recommendation to temporarily suspend use of the Rotarix vaccine. FDA has determined it is appropriate for clinicians and health care professionals to resume the use of Rotarix and to continue the use of RotaTeq.
FDA considered the following information in its decision:
FDA is working with each of the manufacturers (GSK and Merck) to update the labeling for both Rotarix and RotaTeq vaccines to include information about the presence of PCV1 (Rotarix) and DNA from PCV1 and PCV2 (RotaTeq) in the vaccines.
FDA is working with each of the manufacturers to plan the appropriate follow up studies, taking into account the input received from members of the VRBPAC on May 7, 2010.
FDA and the manufacturers will continue to investigate the findings of PCV in rotavirus vaccines, and will evaluate information from ongoing testing by FDA and the manufacturers. As noted by the firm during the May 7, 2010, VRBPAC meeting, GSK plans to re-derive its vaccine, in consultation with FDA. Merck is in the early stages of its investigation, and has not yet determined next steps in this regard.
FDA has determined it is appropriate for clinicians and health care professionals to resume the use of Rotarix and to continue the use of RotaTeq. FDA also recommends that clinicians and public health professionals inform parents of the findings of PCV DNA or PCV in rotavirus vaccines, and that there is no evidence that these findings pose a safety risk in humans. Both the prescribing information and patient labeling will be revised to include this information.
The benefits of vaccination against rotavirus disease are substantial, both in the United States and the developing world and far outweigh any theoretical risk posed by PCV types 1 and 2. The safety record of both rotavirus vaccines is excellent.
FDA will keep the public and clinical community updated through www.fda.gov. For questions, please contact the GSK response center at 1-888-825-5249 or call the Delaware Division of Public Health Immunization Program at 1-800-282-8672.
