List Of COVID-19 Vaccine Authorizations
National regulatory authorities have granted full or emergency use authorizations for 40 COVID-19 vaccines. Ten vaccines have been approved for emergency or full use by at least one stringent regulatory authority recognized by the World Health Organization (WHO): Pfizer–BioNTech, Oxford–AstraZeneca, Sinopharm BIBP, Moderna, Janssen, CoronaVac, Covaxin, Novavax, Convidecia, and Sanofi–GSK. Seven others are under assessment by the WHO: Sputnik V, Sinopharm WIBP, Abdala, Zifivax, Corbevax, COVIran Barekat, and SCB-2019. Of the 40 vaccines, 16 have a full or emergency authorization in only one country, 12 in ten or fewer countries, and 12 in more than ten countries. Note that in some countries, vaccines may be authorized solely for travel purposes. They may not be approved for the general population. For example, the CoronaVac, Covishield, BBIBP-CorV and Covaxin vaccines are not part of Australia's national vaccination program; however, they are recognized for the p ...

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. ...

Inactivated Vaccine
An inactivated vaccine (or killed vaccine) is a vaccine consisting of virus particles, bacteria, or other pathogens that have been grown in culture and then killed to destroy disease-producing capacity. In contrast, live vaccines use pathogens that are still alive (but are almost always attenuated, that is, weakened). Pathogens for inactivated vaccines are grown under controlled conditions and are killed as a means to reduce infectivity and thus prevent infection from the vaccine. Inactivated vaccines were first developed in the late 1800s and early 1900s for cholera, plague, and typhoid. Today, inactivated vaccines exist for many pathogens, including influenza, polio (IPV), rabies, hepatitis A and pertussis. Because inactivated pathogens tend to produce a weaker response by the immune system than live pathogens, immunologic adjuvants and multiple "booster" injections may be required in some vaccines to provide an effective immune response against the pathogen. Attenuated vacci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sputnik Light
Sputnik Light (russian: Спутник Лайт, Sputnik Layt or Lajt) is a single dose COVID-19 vaccine developed by the Gamaleya Research Institute of Epidemiology and Microbiology. It consists of the first dose of the Sputnik V vaccine, which is based on the Ad26 vector, and it can be stored at a normal refrigerator temperature of . The institute says this version would be ideally suited for areas with acute outbreaks, allowing more people to be vaccinated quickly. It will also be used as a third (booster) dose for those who received Sputnik V at least 6 months earlier. Effectiveness A vaccine is generally considered effective if the estimate is ≥50% with a >30% lower limit of the 95% confidence interval. As of September 2021, no study on Sputnik Light reported confidence intervals, so it is not possible to know the accuracy of the estimates. Effectiveness is generally expected to slowly decrease over time. A real-world study with participants aged 60–79 years in Ar ...

Viral Vector Vaccine
A viral vector vaccine is a vaccine that uses a viral vector to deliver genetic material ( DNA), which can be transcribed by the recipient's host cells as mRNA coding for a desired protein (or: antigen) to elicit an immune response. , six viral vector vaccines have been authorized for use in humans in at least one country: four COVID-19 vaccines and two Ebola vaccines. Technology Viral vector vaccines use a modified version of one virus as a vector to deliver to a cell a nucleic acid coding for an antigen for another infectious agent. Viral vector vaccines do not cause infection with either the virus used as the vector, or the source of the antigen. The genetic material it delivers does not integrate into a person's genome. Viral vector vaccines enable antigen expression within cells and induce a robust cytotoxic T cell response, unlike subunit vaccines which only confer humoral immunity. Most viral vectors are designed to be incapable of replication because the necessary gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNA Vaccine
A DNA vaccine is a type of vaccine that transfects a specific antigen-coding DNA sequence into the cells of an organism as a mechanism to induce an immune response. DNA vaccines work by injecting genetically engineered plasmid containing the DNA sequence encoding the antigen(s) against which an immune response is sought, so the cells directly produce the antigen, thus causing a protective immunological response. DNA vaccines have theoretical advantages over conventional vaccines, including the "ability to induce a wider range of types of immune response". Several DNA vaccines have been tested for veterinary use. In some cases, protection from disease in animals has been obtained, in others not. Research is ongoing over the approach for viral, bacterial and parasitic diseases in humans, as well as for cancers. In August 2021, Indian authorities gave emergency approval to ZyCoV-D. Developed by Cadila Healthcare, it is the first DNA vaccine approved for humans. History Con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 immune 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] |
COVID-19 Vaccination In Australia
The general COVID-19 vaccination in Australia program began on 22 February 2021 in response to the COVID-19 pandemic, with the goal of vaccinating all willing people in Australia before 2022. Front-line workers and aged care staff and residents had priority for being inoculated, before a gradual phased release to less-vulnerable and lower-risk population groups throughout 2021. The Therapeutic Goods Administration (TGA) approved four vaccines for Australian use in 2021: the Pfizer–BioNTech vaccine on 25 January, the Oxford–AstraZeneca vaccine on 16 February, Janssen vaccine on 25 June and the Moderna vaccine on 9 August. Although approved for use, the Janssen vaccine was not included in the Australian vaccination program . As of 3 August 2022, Australia had administered 62,492,656 vaccine doses across the country.(The data on this site changes daily)( The data on this site changes daily.)( The data on this site changes daily) The country's vaccination rollout initia ...
