RNA Vaccine
An mRNA vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. The vaccine delivers molecules of antigen-encoding mRNA into cells, which use the designed mRNA as a blueprint to build foreign protein that would normally be produced by a pathogen (such as a virus) or by a cancer cell. These protein molecules stimulate an adaptive immune response that teaches the body to identify and destroy the corresponding pathogen or cancer cells. The mRNA is delivered by a co-formulation of the RNA encapsulated in lipid nanoparticles that protect the RNA strands and help their absorption into the cells. Reactogenicity, the tendency of a vaccine to produce adverse reactions, is similar to that of conventional non-RNA vaccines. People susceptible to an autoimmune response may have an adverse reaction to messenger RNA vaccines. The advantages of mRNA vaccines over traditional vaccines are ease of design, speed and lower cost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humoral Immunity
Humoral immunity is the aspect of immunity (medical), immunity that is mediated by macromolecules – including secreted antibodies, complement proteins, and certain antimicrobial peptides – located in extracellular fluids. Humoral immunity is named so because it involves substances found in the humorism, humors, or body fluids. It contrasts with cell-mediated immunity. Humoral immunity is also referred to as antibody-mediated immunity. The study of the molecular and cellular immunity, cellular components that form the immune system, including their function and interaction, is the central science of immunology. The immune system is divided into a more primitive innate immune system and an acquired or adaptive immune system of vertebrates, each of which contain both humoral and cell (biology), cellular immune elements. Humoral immunity refers to antibody production and the coinciding processes that accompany it, including: Th2 activation and cytokine production, germinal center ...

Regulation Of Therapeutic Goods
The regulation of therapeutic goods, defined as drugs and therapeutic devices, varies by jurisdiction. In some countries, such as the United States, they are regulated at the national level by a single agency. In other jurisdictions they are regulated at the state level, or at both state and national levels by various bodies, as in Australia. The role of therapeutic goods regulation is designed mainly to protect the health and safety of the population. Regulation is aimed at ensuring the safety, quality, and efficacy of the therapeutic goods which are covered under the scope of the regulation. In most jurisdictions, therapeutic goods must be registered before they are allowed to be sold. There is usually some degree of restriction on the availability of certain therapeutic goods, depending on their risk to consumers. History Modern drug regulation has historical roots in the response to the proliferation of universal antidotes which appeared in the wake of Mithridates' death. ...

Medicines And Healthcare Products Regulatory Agency
The Medicines and Healthcare products Regulatory Agency (MHRA) is an executive agency of the Department of Health and Social Care in the United Kingdom which is responsible for ensuring that medicines and medical devices work and are acceptably safe. The MHRA was formed in 2003 with the merger of the Medicines Control Agency (MCA) and the Medical Devices Agency (MDA). In April 2013, it merged with the National Institute for Biological Standards and Control (NIBSC) and was rebranded, with the MHRA identity being used solely for the regulatory centre within the group. The agency employs more than 1,200 people in London, York and South Mimms, Hertfordshire. Structure The MHRA is divided into three main centres: * MHRA Regulatory – the regulator for the pharmaceutical and medical devices industries * Clinical Practice Research Datalink – licences anonymised health care data to pharmaceutical companies, academics and other regulators for research * National Institute for ...

COVID-19 Vaccine
A COVID19 vaccine is a vaccine intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 ( COVID19). Knowledge about the structure and function of previous coronaviruses causing diseases like severe acute respiratory syndrome ( SARS) and Middle East respiratory syndrome ( MERS) accelerated the development of various vaccine platforms in early 2020. In 2020, the first COVID19 vaccines were developed and made available to the public through emergency authorizations and conditional approvals. However, immunity from the vaccines wanes over time, requiring people to get booster doses of the vaccine to maintain protection against COVID19. The COVID19 vaccines are widely credited for their role in reducing the spread of COVID19 and reducing the severity and death caused by COVID19. Many countries implemented phased distribution plans that prioritized those at highest risk of comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RNA Therapeutics
RNA therapeutics are a new class of medications based on RNA, ribonucleic acid (RNA). Research has been working on clinical use since the 1990s, with significant success in cancer therapy in the early 2010s. In 2020 and 2021, mRNA vaccines have been developed globally for use in combating the coronavirus disease 2019, coronavirus disease (COVID-19 pandemic). The Pfizer–BioNTech COVID-19 vaccine was the first mRNA vaccine approved by a Regulation of therapeutic goods, medicines regulator, followed by the Moderna COVID-19 vaccine, and others. The main types of RNA therapeutics are those based on messenger RNA (mRNA), antisense RNA (asRNA), RNA interference (RNAi), RNA activation (RNAa) and RNA aptamers. Of the four types, mRNA-based therapy is the only type which is based on triggering Protein biosynthesis, synthesis of proteins within cells, making it particularly useful in vaccine development. Antisense RNA is complementary to coding mRNA and is used to trigger mRNA inactivation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
