CDC publishes report on Tdap vaccination of pregnant women enrolled in Medicaid
CDC published Vaccination with Tetanus, Diphtheria, and Acellular Pertussis Vaccine of Pregnant Women Enrolled in Medicaid—Michigan, 2011–2013 in the September 26 issue of MMWR (pages 839–842). A summary made available to the press is reprinted below.
Vaccinating pregnant women with tetanus, diphtheria and acellular pertussis (Tdap) vaccines is an important strategy for providing passive immunity to infants, who are at highest risk of mortality and morbidity from pertussis. In 2011, the Advisory Committee on Immunization Practices (ACIP) first recommended the routine administration of Tdap during pregnancy. Using Michigan Medicaid administrative claims data and statewide immunization information system data, this is the first study to examine Tdap vaccination among a publicly insured cohort of pregnant women. Results indicated that only 14.3% of women received Tdap during pregnancy, with rates highest among whites and lowest among Arab women. Ensuring that all infants receive the protection against pertussis afforded by maternal vaccination will require enhanced efforts, including increased education of health care providers, parents, and families.
Wall Street Journal features editorial by Dr. Paul Offit about the epidemic of misguided vaccine distrust
On September 24, the Wall Street Journal published an editorial by Paul Offit, MD, director, Vaccine Education Center at the Children's Hospital of Philadelphia, titled The Anti-Vaccination Epidemic. In this column, Dr. Offit describes how well-educated, affluent, but misguided parents who refuse to vaccinate their children are contributing to an increase of vaccine-preventable diseases. The concluding paragraph is reprinted below.
Because we're unwilling to learn from history, we are starting to relive it. And children are the victims of our ignorance. An ignorance that, ironically, is cloaked in education, wealth and privilege.

CDC publishes updated preparedness and response framework for influenza pandemics
CDC published Updated Preparedness and Response Framework for Influenza Pandemics in the September 26 issue of MMWR Recommendations and Reports. Two sentences from each of the first two paragraphs are reprinted below.
On the basis of experience from recent influenza responses, CDC has updated its framework to describe influenza pandemic progression using six intervals (two prepandemic and four pandemic intervals) and eight domains. This updated framework can be used for influenza pandemic planning and serves as recommendations for risk assessment, decision-making, and action in the United States.
Compared with the previous U.S. government stages, this updated framework provides greater detail and clarity regarding the potential timing of key decisions and actions aimed at slowing the spread and mitigating the impact of an emerging pandemic. Use of this updated framework is anticipated to improve pandemic preparedness and response in the United States.
CDC's Health Alert Network publishes an advisory to provide awareness of an acute neurologic syndrome with focal limb weakness in children; CDC is seeking information about other similar neurologic illnesses in all states
On September 26, the CDC Health Alert Network (HAN) issued a CDC Health Advisory titled: Acute Neurologic Illness with Focal Limb Weakness of Unknown Etiology in Children. The "Summary" and "Background" sections are reprinted below. Other advisory sections that you may wish to consult are titled "Recommendations" and “For More Information.”
The Centers for Disease Control and Prevention (CDC) is working closely with the Colorado Department of Public Health and Environment (CDPHE) and Children’s Hospital Colorado to investigate a cluster of nine pediatric patients hospitalized with acute neurologic illness of undetermined etiology. The illness is characterized by focal limb weakness and abnormalities of the spinal cord gray matter on MRI. These illnesses have occurred since August 1, 2014 coincident with an increase of respiratory illnesses among children in Colorado. The purpose of this HAN Advisory is to provide awareness of this neurologic syndrome under investigation with the aim of determining if children with similar clinical and radiographic findings are being cared for in other geographic areas. Guidance about reporting cases to state and local health departments and CDC is provided. Please disseminate this information to infectious disease specialists, intensive care physicians, pediatricians, neurologists, radiologists/neuroradiologists, infection preventionists, and primary care providers, as well as to emergency departments and microbiology laboratories.
The CDPHE, Children’s Hospital Colorado, and CDC are investigating nine cases of acute neurologic illness among pediatric patients. The cases were identified during August 9–September 17, 2014, among children aged 1–18 years (median age 10 years). Most of the children were from the Denver metropolitan area. All were hospitalized. Common features included acute focal limb weakness and specific findings on magnetic resonance imaging (MRI) of the spinal cord consisting of non-enhancing lesions largely restricted to the gray matter. In most cases, these lesions spanned more than one level of the spinal cord. Some also had acute cranial nerve dysfunction with correlating non-enhancing brainstem lesions on MRI. None of the children experienced altered mental status or seizures. None had any cortical, subcortical, basal ganglia, or thalamic lesions on MRI. Most children reported a febrile respiratory illness in the two weeks preceding development of neurologic symptoms. In most cases, cerebrospinal fluid (CSF) analyses demonstrated mild-moderate pleocytosis (increased cell count in the CSF) consistent with an inflammatory or infectious process. CSF testing to date has been negative for West Nile virus and enteroviruses, including poliovirus. Nasopharyngeal specimens were positive for rhinovirus/enterovirus in six out of eight patients that were tested. Of the six positive specimens, four were typed as EV-D68, and the other two are pending typing results. Testing of other specimens is still in process. Eight out of nine children have been confirmed to be up to date on polio vaccinations. Epidemiologic and laboratory investigations of these cases are ongoing.
The United States is currently experiencing a nationwide outbreak of EV-D68 associated with severe respiratory disease. The possible linkage of this cluster of neurologic disease to this large EV-D68 outbreak is part of the current investigation. CDC is seeking information about other similar neurologic illnesses in all states, especially cases clustered in time and place. CDC has particular interest in characterizing the epidemiology and etiology of such cases.

CDC announces September 28 as World Rabies Day
CDC published Announcements: World Rabies Day—September 28, 2014 in the September 26 issue of MMWR (page 843). The complete announcement is reprinted below.
September 28, 2014, is the 8th annual World Rabies Day. Rabies is a fatal acute encephalitis caused by lyssaviruses. The number of human rabies deaths worldwide is estimated to exceed 55,000 each year. In the United States, wild animal reservoirs serve as the most important source of infection. However, over 90% of human deaths globally are caused by bites by rabid dogs.
Rabies control and prevention efforts focus on elimination of canine rabies through mass vaccination campaigns and treatment of exposed persons with prompt wound care and administration of human rabies immune globulin and vaccine. Although rabies is preventable, a lack of accurate data on the burden of disease, inadequate rabies diagnostic laboratory capacity, and poor access to rabies vaccine for postexposure prophylaxis has delayed progress towards regional goals for human rabies elimination.
Blueprints developed by international rabies experts can be used for the development of country-specific rabies elimination plans. These blueprints focus on describing the epidemiology of rabies, improving surveillance, raising awareness among clinicians and the public, achieving high canine vaccination coverage, and ensuring reliable diagnostic, cold chain, and vaccine procurement capacity.
Despite many challenges, considerable progress has been made in the Western Hemisphere; human rabies mortality has been reduced by more than 90% over the past century. Communicable disease programs proven to be successful in settings similar to those where canine rabies is endemic can be emulated for rabies control and prevention efforts in the future. Also, lessons learned during rabies control efforts can prove valuable for responding to emerging zoonotic diseases.

ACOG releases updated committee opinion on influenza vaccination in pregnancy
In September, the American College of Obstetricians and Gynecologists (ACOG) released an updated committee opinion online titled Influenza Vaccination During Pregnancy. The abstract is reprinted below.
The Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices and the American College of Obstetricians and Gynecologists recommend that all adults receive an annual influenza vaccine. Influenza vaccination is an essential element of preconception, prenatal, and postpartum care because pregnant women are at an increased risk of serious illness due to seasonal and pandemic influenza. Since 2010, influenza vaccination rates among pregnant women have increased but still need significant improvement. It is particularly important that women who are or will be pregnant during influenza season receive an inactivated influenza vaccine as soon as it is available. It is critically important that all obstetrician–gynecologists and all providers of obstetric care advocate for influenza vaccination, provide the influenza vaccine to their pregnant patients, and receive the influenza vaccine themselves every season. It is imperative that obstetrician–gynecologists, other health care providers, health care organizations, and public health officials continue efforts to improve the rate of influenza vaccination among pregnant women.
CDC develops new resources to help healthcare professionals and the public understand the new pneumococcal vaccination recommendations for adults
On September 19, CDC published Use of 13-Valent Pneumococcal Conjugate Vaccine and 23-Valent Pneumococcal Polysaccharide Vaccine Among Adults Aged ≥65 Years: Recommendations of the Advisory Committee on Immunization Practices (ACIP) in MMWR. CDC has developed new resources to help both healthcare professionals and members of the public understand these somewhat complicated new recommendations, and suggests the following activities to help raise awareness.
To help increase awareness of the new recommendations among healthcare professionals
Influenza is serious; many resources are available to aid healthcare professionals in vaccinating
Vaccination remains the single most effective means of preventing influenza, and is recommended for everyone age six months and older. If you don't provide influenza vaccination in your clinic, please recommend vaccination to your patients and refer them to a clinic or pharmacy that provides vaccines or to the HealthMap Vaccine Finder to locate sites near their workplaces or homes that offer influenza vaccination services.
Following is a list of resources related to influenza disease and vaccination for healthcare professionals and the public:

CDC publishes an MMWR Supplement about estimating the future number of Ebola cases
CDC published Estimating the Future Number of Cases in the Ebola Epidemic—Liberia and Sierra Leone, 2014–2015 in a September 26 MMWR Supplement. The first portion of the "Abstract" section is reprinted below.
The first cases of the current West African epidemic of Ebola virus disease (hereafter referred to as Ebola) were reported on March 22, 2014, with a report of 49 cases in Guinea. By August 31, 2014, a total of 3,685 probable, confirmed, and suspected cases in West Africa had been reported. To aid in planning for additional disease-control efforts, CDC constructed a modeling tool called EbolaResponse to provide estimates of the potential number of future cases. If trends continue without scale-up of effective interventions, by September 30, 2014, Sierra Leone and Liberia will have a total of approximately 8,000 Ebola cases. A potential underreporting correction factor of 2.5 also was calculated. Using this correction factor, the model estimates that approximately 21,000 total cases will have occurred in Liberia and Sierra Leone by September 30, 2014. Reported cases in Liberia are doubling every 15–20 days, and those in Sierra Leone are doubling every 30–40 days.
