Janssen COVID-19 Vaccine
The Janssen COVID19 vaccine, (Ad26.COV2.S) sold under the brand name Jcovden, is a COVID19 vaccine that was developed by Janssen Vaccines in Leiden, Netherlands, and its Belgium, Belgian parent company Janssen Pharmaceuticals, a subsidiary of American company Johnson & Johnson. It is a viral vector vaccine based on a human adenovirus that has been modified to contain the gene for making the coronavirus spike protein, spike protein of the SARS-CoV-2 virus that causes COVID19. The body's immune system responds to this spike protein to produce Antibody, antibodies. The vaccine requires only one dose and does not need to be stored frozen. Clinical trials for the vaccine were started in June 2020, with Phase III trials, phaseIII involving around 43,000 people. In January 2021, Janssen announced that 28 days after a completed vaccination, the vaccine was 66% effective in a one-dose regimen in preventing symptomatic COVID19, with an 85% efficacy in preventing severe COVID19 and 100 ...

Severe Acute Respiratory Syndrome Coronavirus 2
Severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) is a strain of coronavirus that causes COVID-19, the respiratory illness responsible for the COVID-19 pandemic. The virus previously had the Novel coronavirus, provisional name 2019 novel coronavirus (2019-nCoV), and has also been called human coronavirus 2019 (HCoV-19 or hCoV-19). First identified in the city of Wuhan, Hubei, China, the World Health Organization designated the outbreak a public health emergency of international concern from January 30, 2020, to May 5, 2023. SARS‑CoV‑2 is a positive-sense single-stranded RNA virus that is Contagious disease, contagious in humans. SARS‑CoV‑2 is a strain of the species ''Betacoronavirus pandemicum'' (SARSr-CoV), as is SARS-CoV-1, the virus that caused the 2002–2004 SARS outbreak. There are animal-borne coronavirus strains more closely related to SARS-CoV-2, the most closely known relative being the BANAL-52 bat coronavirus. SARS-CoV-2 is of Zoonosis, z ...

Adenovirus
Adenoviruses (members of the family ''Adenoviridae'') are medium-sized (90–100 nm), nonenveloped (without an outer lipid bilayer) viruses with an icosahedral nucleocapsid containing a double-stranded DNA genome. Their name derives from their initial isolation from human adenoids in 1953. They have a broad range of vertebrate hosts; in humans, more than 50 distinct adenoviral serotypes have been found to cause a wide range of illnesses, from mild respiratory infections in young children (the common cold) to life-threatening multi-organ disease in people with a weakened immune system. Virology Classification This family contains the following genera: * '' Aviadenovirus'' * '' Barthadenovirus'' * '' Ichtadenovirus'' * ''Mastadenovirus'' (including all human adenoviruses) * '' Siadenovirus'' * '' Testadenovirus'' Diversity In humans, currently there are 88 human adenoviruses (HAdVs) in seven species (Human adenovirus A to G): * A: 12, 18, 31 * B: 3, 7, 11, 14, ...

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] |
Thrombosis With Thrombocytopenia Syndrome
Post-vaccination embolic and thrombotic events, termed vaccine-induced immune thrombotic thrombocytopenia (VITT), vaccine-induced prothrombotic immune thrombocytopenia (VIPIT), thrombosis with thrombocytopenia syndrome (TTS), vaccine-induced immune thrombocytopenia and thrombosis (VITT), or vaccine-associated thrombotic thrombocytopenia (VATT), are rare types of blood clotting syndromes that were initially observed in a number of people who had previously received the Oxford–AstraZeneca COVID‑19 vaccine (AZD1222) during the COVID‑19 pandemic. It was subsequently also described in the Janssen COVID‑19 vaccine (Johnson & Johnson), leading to the suspension of its use until its safety had been reassessed. On 5 May 2022 the FDA posted a bulletin limiting the use of the Janssen Vaccine to very specific cases due to further reassessment of the risks of TTS, although the FDA also stated in the same bulletin that the benefits of the vaccine outweigh the risks. In April 2021, A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marketing Authorisation
Marketing authorisation is the process of reviewing and assessing the evidence to support a medicinal product, such as a drug, in relation to its marketing, finalised by granting of a licence to be sold. This process is performed within a legal framework defining the requirements necessary for successful application to the regulatory authority, details on the assessment procedure (based on quality, efficacy and safety criteria), and also the circumstances where a marketing authorisation already granted may be withdrawn, suspended or revoked. The application dossier for marketing authorisation is called a New Drug Application (NDA) in the USA or Marketing Authorisation Application (MAA) in the European Union and other countries, or simply registration dossier. This contains data proving that the drug has quality, efficacy and safety properties suitable for the intended use, additional administrative documents, samples of finished product or related substances and reagents necessar ...

Phase III Trials
The phases of clinical research are the stages in which scientists conduct experiments with a health intervention to obtain sufficient evidence for a process considered effective as a medical treatment. For drug development, the clinical phases start with testing for drug safety in a few human subjects, then expand to many study participants (potentially tens of thousands) to determine if the treatment is effective. Clinical research is conducted on drug candidates, vaccine candidates, new medical devices, and new diagnostic assays. Description Clinical trials testing potential medical products are commonly classified into four phases. The drug development process will normally proceed through all four phases over many years. When expressed specifically, a clinical trial phase is capitalized both in name and Roman numeral, such as "Phase I" clinical trial. If the drug successfully passes through Phases I, II, and III, it will usually be approved by the national regulatory au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clinical Trial
Clinical trials are prospective biomedical or behavioral research studies on human subject research, human participants designed to answer specific questions about biomedical or behavioral interventions, including new treatments (such as novel vaccines, pharmaceutical drug, drugs, medical nutrition therapy, dietary choices, dietary supplements, and medical devices) and known interventions that warrant further study and comparison. Clinical trials generate data on dosage, safety and efficacy. They are conducted only after they have received institutional review board, health authority/ethics committee approval in the country where approval of the therapy is sought. These authorities are responsible for vetting the risk/benefit ratio of the trial—their approval does not mean the therapy is 'safe' or effective, only that the trial may be conducted. Depending on product type and development stage, investigators initially enroll volunteers or patients into small Pilot experiment, pi ...

Michigan Medicine
The University of Michigan Medicine (branded as Michigan Medicine) is the academic medical center of the University of Michigan, a public research university in Ann Arbor, Michigan. It consists of the university's Medical School, affiliated hospitals, and affiliated healthcare centers. History In 1869 the University of Michigan opened the first hospital in the country owned and operated by a university, in a house in Ann Arbor originally built as a professor's residence. In 1876 a new hospital building was opened adjacent to the old one. At the insistence of the Michigan Legislature, the new building had two separate departments, one for medicine and the other for homeopathy. In 1891 the hospital moved to a set of new buildings away from the university campus, on Catherine Street. The homeopathy department closed in 1921. In 1925 the university opened a hospital building at a cost of $3.85 million. It was designed by Albert Kahn and built by Thompson-Starrett Compan ...

Antibody
An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as pathogenic bacteria, bacteria and viruses, including those that cause disease. Each individual antibody recognizes one or more specific antigens, and antigens of virtually any size and chemical composition can be recognized. Antigen literally means "antibody generator", as it is the presence of an antigen that drives the formation of an antigen-specific antibody. Each of the branching chains comprising the "Y" of an antibody contains a paratope that specifically binds to one particular epitope on an antigen, allowing the two molecules to bind together with precision. Using this mechanism, antibodies can effectively "tag" the antigen (or a microbe or an infected cell bearing such an antigen) for attack by cells of the immune system, or can neutralize it directly (for example, by blocking a p ...
