Vaccine Adverse Event Reporting System
The Vaccine Adverse Event Reporting System (VAERS) is a United States program for vaccine safety, co-managed by the U.S. Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA). VAERS is a postmarketing surveillance program, collecting information about adverse events (possible harmful side effects) that occur after administration of vaccines to ascertain whether the risk–benefit ratio is high enough to justify continued use of any particular vaccine. VAERS, the Vaccine Safety Datalink, and the Clinical Immunization Safety Assessment (CISA) Network are tools by which the CDC and FDA monitor vaccine safety to fulfill their duty as regulatory agencies charged with protecting the public. As it is based on submissions by the public, VAERS is susceptible to unverified reports, misattribution, underreporting, and inconsistent data quality. Raw, unverified data from VAERS has often been used by the anti-vaccine community to justify misinformation ...

Adverse Event Reporting System
The FDA Adverse Event Reporting System (FAERS or AERS) is a computerized information database designed to support the U.S. Food and Drug Administration's (FDA) postmarketing safety surveillance program for all approved drug and therapeutic biologic products. The FDA uses FAERS to monitor for new adverse events and medication errors that might occur with these products. It is a system that measures occasional harms from medications to ascertain whether the risk–benefit ratio is high enough to justify continued use of any particular drug and to identify correctable and preventable problems in health care delivery (such as need for retraining to prevent prescribing errors). The system interacts with several related systems including MedWatch and the Vaccine Adverse Event Reporting System. FAERS replaced legacy AERS system in Sep 2012. Background Reporting of adverse events from the point of care is voluntary in the United States. The FDA receives some adverse event and medicati ...

Empirical Bayes
Empirical Bayes methods are procedures for statistical inference in which the prior probability distribution is estimated from the data. This approach stands in contrast to standard Bayesian methods, for which the prior distribution is fixed before any data are observed. Despite this difference in perspective, empirical Bayes may be viewed as an approximation to a fully Bayesian treatment of a hierarchical model wherein the parameters at the highest level of the hierarchy are set to their most likely values, instead of being integrated out. Empirical Bayes, also known as maximum marginal likelihood, represents a convenient approach for setting hyperparameters, but has been mostly supplanted by fully Bayesian hierarchical analyses since the 2000s with the increasing availability of well-performing computation techniques. Introduction Empirical Bayes methods can be seen as an approximation to a fully Bayesian treatment of a hierarchical Bayes model. In, for example, a two-sta ...

COVID-19 Vaccine Misinformation And Hesitancy
Anti-vaccination activists and other people in many countries have spread a variety of unfounded conspiracy theories and other misinformation about COVID-19 vaccines based on misunderstood or misrepresented science, religion, exaggerated claims about side effects, a story about COVID-19 being spread by 5G, misrepresentations about how the immune system works and when and how COVID-19 vaccines are made, and other false or distorted information. This misinformation has proliferated and may have made many people averse to vaccination. This has led to governments and private organizations around the world introducing measures to incentivize/coerce vaccination, such as lotteries, mandates and free entry to events, which has in turn led to further misinformation about the legality and effect of these measures themselves. Misinformation Various false theories have spread in different parts of the world regarding the COVID-19 vaccines. COVID-19 and variant related claims Pr ...

Anti-vaccine
Vaccine hesitancy is a delay in acceptance, or refusal, of vaccines despite the availability of vaccine services and supporting evidence. The term covers refusals to vaccinate, delaying vaccines, accepting vaccines but remaining uncertain about their use, or using certain vaccines but not others. The scientific consensus that vaccines are generally safe and effective is overwhelming. Vaccine hesitancy often results in disease outbreaks and deaths from vaccine-preventable diseases. Therefore, the World Health Organization characterizes vaccine hesitancy as one of the top ten global health threats. "Anti-vaccinationism" refers to total opposition to vaccination; in more recent years, anti-vaccinationists have been known as "anti-vaxxers" or "anti-vax". Vaccine hesitancy is complex and context-specific, varying across time, place and vaccines. It can be influenced by factors such as lack of proper scientifically based knowledge and understanding about how vaccines are made or wor ...

COVID-19 Pandemic
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of , the pandemic had caused more than cases and confirmed deaths, making it one of the deadliest in history. COVID-19 symptoms range from undetectable to deadly, but most commonly include fever, dry cough, and fatigue. Severe illness is more likely in elderly patients and those with certain underlying medical conditions. COVID-19 transmits when people breathe in air contaminated by droplets and ...

The Incredible Hulk
The Hulk is a superhero appearing in American comic books published by Marvel Comics.

However, he had a change of heart after his son, who was on a gluten-free diet for his autism, ate a waffle at a buffet while his parents were distracted. Laidler says his son's doctors had told him that his son w ...

Autism
The autism spectrum, often referred to as just autism or in the context of a professional diagnosis autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental condition (or conditions) characterized by difficulties in social interaction, verbal and nonverbal communication, and the presence of repetitive behavior and restricted interests. Other common signs include unusual responses to sensory stimuli. Autism is generally understood as a ''spectrum disorder'', which means that it can manifest differently in each person: any given autistic individual is likely to show some, but not all, of the characteristics associated with it, and the person may exhibit them to varying degrees. Some autistic people remain nonspeaking over the course of their lifespan, while others have relatively unimpaired spoken language. There is large variation in the level of support people require, and the same person may present differently at varying times. Historically ...

Thimerosal
Thiomersal (INN), or thimerosal (USAN, JAN), is an organomercury compound. It is a well-established antiseptic and antifungal agent. The pharmaceutical corporation Eli Lilly and Company gave thiomersal the trade name Merthiolate. It has been used as a preservative in vaccines, immunoglobulin preparations, skin test antigens, antivenins, ophthalmic and nasal products, and tattoo inks. In spite of the scientific consensus that fears about its safety are unsubstantiated, its use as a vaccine preservative has been called into question by anti-vaccination groups. Due to this public pressure the substance was phased out of routine childhood vaccines in the United States, the European Union, and a few other countries in response to popular fears. It remains in use as a preservative for annual flu vaccines. History Morris Kharasch, a chemist then at the University of Maryland filed a patent application for thiomersal in 1927; Eli Lilly later marketed the compound under the trade ...
