  • Vaccines and Autism: What You Should Know | Vaccine Education
    Q A Vaccines and Autism: What you should know Volume& 1 Summer 2008 Some parents of children with autism are concerned that vaccines are the cause. Their concerns center on three areas: the combination measles-mumps-rubella (MMR) vaccine; thimerosal, a mercury-containing preservative previously contained in several vaccines; and the notion that babies receive too many vaccines too soon.

  • Electronic Support for Public Health–Vaccine Adverse Event Reporting System (ESP:VAERS)
    Grant Final Report Grant ID: R18 HS 017045 Electronic Support for Public Health–Vaccine Adverse Event Reporting System (ESP:VAERS) Inclusive dates: 12/01/07 - 09/30/10 Principal Investigator: Lazarus, Ross, MBBS, MPH, MMed, GDCompSci Team members: Michael Klompas, MD, MPH Performing Organization: Harvard Pilgrim Health Care, Inc. Project Officer: Steve Bernstein Submitted to: The Agency for Healthcare Research and Quality (AHRQ) U.S. Department of Health and Human Services 540 Gaither Road Rockville, MD 20850 www.ahrq.gov Abstract Purpose: To develop and disseminate HIT evidence and evidence-based tools to improve healthcare decision making through the use of integrated data and knowledge management. Scope: To create a generalizable system to facilitate detection and clinician reporting of vaccine adverse events, in order to improve the safety of national vaccination programs. Methods: Electronic medical records available from all ambulatory care encounters in a large multi-specialty practice were used. Every patient receiving a vaccine was automatically identified, and for the next 30 days, their health care diagnostic codes, laboratory tests, and medication prescriptions were evaluated for values suggestive of an adverse event. Results: Restructuring at CDC and consequent delays in terms of decision making have made it challenging despite best efforts to move forward with discussions regarding the evaluation of ESP:VAERS performance in a randomized trial and comparison of ESP:VAERS performance to existing VAERS and Vaccine Safety Datalink data. However, Preliminary data were collected and analyzed and this initiative has been presented at a number of national symposia. Key Words: electronic health records, vaccinations, adverse event reporting The authors of this report are responsible for its content.

  • AAP Immunizations Frequently Asked Questions: Vaccine Safety
    AAP Immunizations Frequently Asked Questions: Vaccine Safety As a parent, you might have questions and concerns about vaccine safety. With so much incorrect information on the Internet and in the media, it is often hard to find trustworthy, clear, and up-to-date information. The truth is that today’s vaccines are the most effective and safest in history and have protected and saved millions of lives from vaccine-preventable diseases. However, some children are too young or too sick to receive vaccines. And some children do have side effects. Listed below are common questions about vaccine safety and the AAP’s response. How are vaccines licensed and monitored to ensure their safety? The Food and Drug Administration (FDA) tests new vaccines for up to 10 years before issuing the vaccine a license. All vaccines must be safe and proven to work well in children. Once the vaccine is being used, the FDA and the Centers for Disease Control and Prevention (CDC) monitor it through the Vaccine Adverse Event Reporting System (VAERS). Researchers look for any problem with a vaccine, inspect the problem, and decide what to do. When VAERS found a problem in the past, changes included: • Using different labels or packaging, • Sending safety alerts, • Inspecting manufacturers' records, and • Taking away the vaccine's license. For more information about VAERS, visit http://vaers.hhs.gov/index or call the toll-free VAERS information line at 1-800-822-7967. For more information about licensing vaccines, visit http://www.aap.org/immunization/families/VaccineSafety_parenthandout.pdf The Vaccine Safety Datalink (VSD) is a collaborative effort between the Centers for Disease Control and Prevention and 9 managed care organizations (MCOs) in the United States.

  • Vaccine Safety Monitoring
    Vaccine Safety Monitoring Vaccine Safety Vaccines are the best way to prevent serious illnesses and death from many infectious diseases. (Get Quick Facts and Resources for Kentucky Residents.) The Food and Drug Administration (FDA) adheres to rigorous testing standards before licensing vaccines. Vaccines are developed through the same general process used to develop drugs and medicines. Vaccine Development 101 A sponsor who wishes to begin clinical trials with a vaccine must apply to the FDA. In their application, they must describe the vaccine, how it is manufactured, and the quality control tests that are done. The applications must also include information about the vaccine’s safety and the results of testing in animals. If the application is approved the vaccine can be tested on people during clinical trials. These trials are typically done in three phases. Phase 1 studies are performed in a small number of closely monitored subjects. Phase 2 studies may enroll hundreds of subjects. Phase 3 trials typically enroll thousands of people. These trials are used to document vaccine effectiveness. They also provide important additional safety data required for licensing. At any stage of the studies in animals or humans, if data raise significant concerns about either safety or effectiveness, the FDA may request additional information or studies, or may halt ongoing clinical studies. After reviewing clinical trial results and the proposed vaccine label, inspecting the facility where the vaccine will be made, and reviewing the vaccine production process, the FDA may decide to license the vaccine. The FDA also authorizes Emergency Use when justified. Find out more about Emergency Use Authorizations.

  • Immunizations and Exemptions
    IMMUNIZATIONS AND EXEMPTIONS Policy Position | 2020-2021 Policy Council In order to protect the health of the public effectively, Texas Nurses Association (TNA) supports policies that mandate “all individuals receive immunizations against-preventable diseases according to the best and most current evidence outlined by the Centers for Disease Control and Prevention (CDC) and the Advisory Committee on Immunization Practices (ACIP),” in line with the American Nurses Association (ANA) revised position statement on immunizations. Registered nurses (RNs) along with all health care workers should be vaccinated based on the guidance for health care workers put forth by the CDC and ACIP. TNA does not support exemptions from immunization, except for annually documented and recertified medical contradictions. Furthermore, TNA does not support philosophical or religious exemptions to immunizations. People with documented medical exemptions may be required to reduce the chance of infectious disease transmission through workplace protective measures or practices, and employers should support and offer these reasonable accommodations. Development of safe vaccinations readily available to everyone is essential to protecting public health. TNA supports ongoing research into prevention and control of novel infectious diseases, such as COVID-19. TNA further collaborates with the Texas Department of State Health Services Immunization Unit, the Immunization Partnership, and the Texas Public Health Coalition.

  • 01-05 STATEMENT of POLICY Vaccine Safety
    01-05 STATEMENT OF POLICY Vaccine Safety Policy Confidence in the safety of vaccines is critical to assuring that they are used as widely, effectively, and appropriately as possible to protect the residents and visitors of our nation. Assuring this safety, from the manufacturing to the administration stages, is a shared responsibility of all levels of public health, the medical community, and the private sector. In order to attain and sustain the necessary level of assurance, the National Association of County and City Health Officials (NACCHO) urges the following: • Vigorous post-licensure safety monitoring and sharing of safety-related data with local health departments for all vaccines on the market. • Increased federal funding and support to help local health departments utilize vaccine use and disease incidence data to identify gaps in vaccine use patterns. • Increased federal funding and support to local health departments to improve their ability to identify and understand vaccine safety and hesitancy concerns among populations within their jurisdictions. • Increased federal funding and support to help local health departments translate research on vaccine hesitancy, develop effective messaging, and institute evidence-based interventions to counter vaccine hesitancy due to safety concerns. • Increased federal funding and support for locally-driven educational efforts geared towards physicians and other health care personnel regarding the safety of vaccines, true contraindications, the risks of delayed vaccine schedules, and the process for and importance of reporting adverse events. • Increased federal funding and support for local health departments to educate medical care providers as well as the public about safety monitoring systems, including how data is analyzed and disseminated.

The project began in 1990 with the primary purpose of rigorously evaluating concerns about the safety of vaccines. Computerized data on vaccination, medical outcome (e.g. outpatient visits, emergency room visits, hospitalizations, and deaths) and covariates (e.g. birth certificates, census data) are prospectively collected and linked under joint protocol at multiple health maintenance organizations for analysis. Approximately 6 million persons (2% of the population of the USA) are now members of health maintenance organizations participating in the Vaccine Safety Datalink, which has proved to be a valuable resource providing important information on a number of vaccine safety issues. The databases and infrastructure created for the Vaccine Safety Datalink have also provided opportunities to address vaccination coverage, cost-effectiveness and other matters connected with immunization as well as matters outside this field.

Preliminary results from the VSD Thimerosal Screening Study published in control Study 2003 did not find an association between thimerosal exposure and autism risk and recent ecological studies have not found a correlation between thimerosal content of vaccines and autism rates. Autism, however, can be difficult to diagnose and the studies to date have relied on computerized clinical or administrative databases in which the validity of the autism diagnoses have not been fully validated. The Thimerosal and Autism Study is a case-control study conducted in three U.S. MCOs. Data collection began in 2005 and took three years to complete. In this study, children who were diagnosed with autism were matched with control children. The autism diagnosis of the case samples was confirmed by a standardized clinical assessment protocol. Vaccination histories and information on other potential confounding factors were confirmed by reviewing the medical records for all children. In addition, the mothers of both cases and matched controls were interviewed. The IOM Immunization Safety Review Committee recommended such a study in 2001. 2001 IOM Recommendations: Thimerosal 1 & 4 Autism and This study was prompted by findings reported to the Institute of Medicine by Blaxill in Ecological Published in Autism Thimerosal- July 2001, which showed increases in autism incidence in California in association Cohort American Containing Vaccines: with increases in the use of thimerosal-containing vaccines during the 1990s.
