Adverse Events
An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An adverse event can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. AEs in patients participating in clinical trials must be reported to the study sponsor and if required could be reported to the local ethics committee. Adverse events categorized as "serious" (results in death, illness requiring hospitalization, events deemed life-threatening, results in persistent or significant incapacity, a congenital anomaly, birth defect or medically important condition) must be reported to the regulatory authorities immediately, whereas non-serious adverse events are ...

Institutional Review Board
An institutional review board (IRB), also known as an independent ethics committee (IEC), ethical review board (ERB), or research ethics board (REB), is a committee that applies research ethics by reviewing the methods proposed for research to ensure that they are ethical. Such boards are formally designated to approve (or reject), monitor, and review biomedical and behavioral research involving humans. They often conduct some form of risk-benefit analysis in an attempt to determine whether or not research should be conducted. The purpose of the IRB is to assure that appropriate steps are taken to protect the rights and welfare of humans participating as subjects in a research study. Along with developed countries, many developing countries have established national, regional or local Institutional Review Boards in order to safeguard ethical conduct of research concerning both national and international norms, regulations or codes. A key goal of IRBs is to protect human subjects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adverse Outcome Pathway
An adverse outcome pathway (AOP) is structured representation of biological events leading to adverse effects and is considered relevant to risk assessment. The AOP links in a linear way existing knowledge along one or more series of causally connected key events (KE) between two points — a molecular initiating event (MIE) and an adverse outcome (AO) that occur at a level of biological organization relevant to risk assessment. The linkage between the events is described by key event relationships (KER) that describe the causal relationships between the key events. AOPs are important for expanding the use of mechanistic toxicological data for risk assessment and regulatory applications with recent applications in further disciplines such as climate science. Background In 2012, the Organisation for Economic Co-operation and Development (OECD) launched a new programme on the development of adverse outcome pathways. A guidance document describes in detail how AOPs are to be d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yellow Card Scheme
The Yellow Card Scheme is the United Kingdom's system for collecting information on suspected adverse drug reactions (ADRs) to medicines. The scheme allows the safety of the medicines and vaccines that are on the market to be monitored. History The scheme was founded in 1964 after the thalidomide disaster, and was developed by Bill Inman. It is run by the Medicines and Healthcare products Regulatory Agency (MHRA) and the Commission on Human Medicines. It was extended to hospital pharmacists in 1997, and to community pharmacists in 1999. The Yellow Card Centre Scotland is a joint venture between MHRA and the Scottish Government. Scope Suspected adverse reactions are collected on all licensed medicines and vaccines, whether issued on prescription or bought over the counter from a pharmacist or supermarket. The scheme also includes all herbal preparations and unlicensed medicines. Adverse reactions can be reported by anyone; this is usually done by healthcare professionals ...

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 ...

Vaccine-associated Enhanced Respiratory Disease
Vaccine-associated enhanced respiratory disease (VAERD), or simply enhanced respiratory disease (ERD), refers to an adverse event where an exacerbated course of respiratory disease occurs with higher incidence in the vaccinated population in comparison with the control group. It is one of the barriers against vaccine development and can lead to its failure. Immunologically, VAERD is characterized with an exaggerated Th2 response and eosinophilic pulmonary infiltrations. It is thought to arise as a result of antibody-mediated complement activation followed by weak neutralization. Historical instances of the phenomenon were seen in vaccine candidates for respiratory syncytial virus, SARS-CoV, Middle East Respiratory Syndrome (MERS), as well as some Influenza strains. During the efforts to develop COVID-19 vaccines, whose target, SARS-CoV2, belongs to the same viral subfamily as SARS-CoV and MERS, concerns were raised about the possibility of exhibiting VAERD. Despite being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clinical Trials Directive
The Clinical Trials Directive (Officially Directive 2001/20/EC of 4 April 2001, of the European Parliament and of the Council on the approximation of the laws, regulations and administrative provisions of the Member States relating to implementation of good clinical practice in the conduct of clinical trials on medicinal products for human use) is a European Union directive that aimed at facilitating the internal market in medicinal products within the European Union, while at the same time maintaining an appropriate level of protection for public health. It seeks to simplify and harmonise the administrative provisions governing clinical trials in the European Community, by establishing a clear, transparent procedure. The Member States of the European Union had to adopt and publish before 1 May 2003 the laws, regulations and administrative provisions necessary to comply with this Directive. The Member States had to apply these provisions at the latest with effect from 1 May 2004. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EudraVigilance
EudraVigilance (European Union Drug Regulating Authorities Pharmacovigilance) is the European data processing network and management system for reporting and evaluation of suspected adverse reactions to medicines which have been authorised or being studied in clinical trials in the European Economic Area (EEA). The European Medicines Agency (EMA) operates the system on behalf of the European Union (EU) medicines regulatory network. The European EudraVigilance system deals with the: * Electronic exchange of Individual Case Safety Reports (ICSR, based on the ICH E2B specifications): ** EudraVigilance Clinical Trial Module (EVCTM) for reporting Suspected Unexpected Serious Adverse Reactions ( SUSARs). ** EudraVigilance Post-Authorisation Module (EVPM) for post-authorisation ICSRs. * Early detection of possible safety signals from marketed drugs for human use.CIOMS Working Group VIII.

Pharmacovigilance
Term Given By Tushar Sharma (UPES Batch 2025) Pharmacovigilance (PV, or PhV), also known as drug safety, is the pharmaceutical science relating to the "collection, detection, assessment, monitoring, and prevention" of adverse effects with pharmaceutical products. The etymological roots for the word "pharmacovigilance" are: (Greek for drug) and (Latin for to keep watch). As such, pharmacovigilance heavily focuses on adverse drug reactions (ADR), which are defined as any response to a drug which is noxious and unintended, including lack of efficacy (the condition that this definition only applies with the doses normally used for the prophylaxis, diagnosis or therapy of disease, or for the modification of physiological disorder function was excluded with the latest amendment of the applicable legislation). Medication errors such as overdose, and misuse and abuse of a drug as well as drug exposure during pregnancy and breastfeeding, are also of interest, even without an adverse ev ...

Antibody-dependent Enhancement
Antibody-dependent enhancement (ADE), sometimes less precisely called immune enhancement or disease enhancement, is a phenomenon in which binding of a virus to suboptimal antibodies enhances its entry into host cells, followed by its replication. The suboptimal antibodies can result from natural infection or from vaccination. ADE may cause enhanced respiratory disease, but is not limited to respiratory disease. It has been observed in HIV, RSV virus and Dengue virus and is monitored for in vaccine development. Technical description In ADE, antiviral antibodies promote viral infection of target immune cells by exploiting the phagocytic FcγR or complement pathway. After interaction with a virus, the antibodies bind Fc receptors (FcR) expressed on certain immune cells or complement proteins. FcγRs bind antibodies via their fragment crystallizable region (Fc). The process of phagocytosis is accompanied by virus degradation, but if the virus is not neutralized (either due t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adverse Vaccine Event
A vaccine adverse event (VAE), sometimes referred to as a vaccine injury, is an adverse event caused by vaccination. The World Health Organization (WHO) knows VAEs as Adverse Events Following Immunization (AEFI). AEFIs can be related to the vaccine itself (product or quality defects), to the vaccination process (administration error or stress related reactions) or can occur independently from vaccination (coincidental). Most vaccine adverse events are mild. Serious injuries and deaths caused by vaccines are very rare, and the idea that severe events are common has been classed as a "common misconception about immunization" by the WHO. Some claimed vaccine injuries are not, in fact, caused by vaccines; for example, there is a subculture of advocates who attribute their children's autism to vaccine injury, despite the fact that vaccines do not cause autism. Claims of vaccine injuries appeared in litigation in the United States in the latter part of the 20th century. Some families ...
