Flu Shot
Influenza vaccines, colloquially known as flu shots or the flu jab, are vaccines that protect against infection by influenza viruses. New versions of the vaccines are developed twice a year, as the influenza virus rapidly changes. While their effectiveness varies from year to year, most provide modest to high protection against influenza. Vaccination against influenza began in the 1930s, with large-scale availability in the United States beginning in 1945. Both the World Health Organization and the US Centers for Disease Control and Prevention (CDC) recommend yearly vaccination for nearly all people over the age of six months, especially those at high risk, and the influenza vaccine is on the World Health Organization's List of Essential Medicines. The European Centre for Disease Prevention and Control (ECDC) also recommends yearly vaccination of high-risk groups, particularly pregnant women, the elderly, children between six months and five years, and those with certain hea ...

Inactivated Vaccine
An inactivated vaccine (or killed vaccine) is a type of vaccine that contains pathogens (such as virus or bacteria) that have been killed or rendered inactive, so they cannot replicate or cause disease. 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. In 1897, Japanese scientists developed an inactivated vaccine for the bubonic plague. In the 1950s, Jonas Salk created an inactivated vaccine for the poliovirus, creating the first vaccine that was both safe and effective against polio. Today, inactivated vaccines exist for many pathogens, including influenza, polio (IPV), rabies, hepatitis A, CoronaVac, Covaxin and pertussis. Because ...

Macfarlane Burnet
Sir Frank Macfarlane Burnet (3 September 1899 – 31 August 1985), usually known as Macfarlane or Mac Burnet, was an Australian virologist known for his contributions to immunology. He won a Nobel Prize in 1960 for predicting acquired immune tolerance. He also developed the theory of clonal selection. Burnet received his Doctor of Medicine degree from the University of Melbourne in 1924, and his PhD from the University of London in 1928. He went on to conduct pioneering research in microbiology and immunology at the Walter and Eliza Hall Institute of Medical Research, Melbourne, and served as director of the Institute from 1944 to 1965. From 1965 until his retirement in 1978, Burnet worked at the University of Melbourne. Throughout his career he played an active role in the development of public policy for the medical sciences in Australia and was a founding member of the Australian Academy of Science (AAS), and served as its president from 1965 to 1969. Burnet's major achie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jonas Salk
Jonas Edward Salk (; born Jonas Salk; October 28, 1914June 23, 1995) was an American virologist and medical researcher who developed one of the first successful polio vaccines. He was born in New York City and attended the City College of New York and New York University School of Medicine. In 1947, Salk accepted a professorship at the University of Pittsburgh School of Medicine, where he undertook a project beginning in 1948 to determine the number of different types of poliovirus. For the next seven years, Salk devoted himself to developing a vaccine against polio. Salk was immediately hailed as a "miracle worker" when the vaccine's success was first made public in April 1955, and chose to not patent the vaccine or seek any profit from it in order to maximize its global distribution. The National Foundation for Infantile Paralysis and the University of Pittsburgh looked into patenting the vaccine, but since Salk's techniques were not novel, their patent attorney said, ...

Ernest William Goodpasture
Ernest William Goodpasture (October 17, 1886 – September 20, 1960) was an American pathologist and physician. Goodpasture advanced the scientific understanding of the pathogenesis of infectious diseases, parasitism, and a variety of rickettsial and viral infections. Together with colleagues at Vanderbilt University, he invented methods for growing viruses and rickettsiae in chicken embryos and fertilized chicken eggs. This enabled the development of vaccines against influenza, chicken pox, smallpox, yellow fever, typhus, Rocky mountain spotted fever, and other diseases. He also identified and described what would become known as Goodpasture syndrome.Valentini, Rudolph PPediatric Anti-GBM Disease (Goodpasture Syndrome). Accessed 8-28-2009. Education and professional career Goodpasture was born in Clarksville, Tennessee, in 1886. He received his B.A. from Vanderbilt University in 1908.

Antiserum
In immunology, antiserum is a blood serum containing antibodies (either monoclonal or polyclonal) that is used to spread passive immunity to many diseases via blood donation ( plasmapheresis). For example, convalescent serum, or passive antibody transfusion from a previous human survivor, was the only known effective treatment for Ebola infection with a high success rate of 7 out of 8 patients surviving. Antisera are widely used in diagnostic virology laboratories. The most common use of antiserum in humans is as antitoxin or antivenom to treat envenomation. Serum therapy, also known as serotherapy, describes the treatment of infectious diseases using the serum of animals that have been immunized against the specific organism or components of that organism that is causing the infection. History In 1890, Emil von Behring and Kitasato Shibasaburō published their first paper on serum therapy. Behring pioneered the technique, using guinea pigs to produce serum. Based ...

Hemophilus Influenzae
''Haemophilus influenzae'' (formerly called Pfeiffer's bacillus or ''Bacillus influenzae'') is a Gram-negative, Motility, non-motile, Coccobacillus, coccobacillary, facultative anaerobic organism, facultatively anaerobic, Capnophile, capnophilic pathogenic bacterium of the family Pasteurellaceae. The bacteria are Mesophile, mesophilic and grow best at temperatures between 35 and 37 °C. ''H. influenzae'' was first described in 1893 by Richard Friedrich Johannes Pfeiffer, Richard Pfeiffer during an influenza pandemic when he incorrectly identified it as the causative microbe, which is why the bacteria was given the name "influenzae". ''H. influenzae'' is responsible for a wide range of localized and invasive infections, typically in infants and children, including pneumonia, meningitis, or bloodstream infections. Treatment consists of antibiotics; however, ''H. influenzae'' is often resistant to the penicillin family, but amoxicillin/clavulanic acid can be used in mild cases ...

Oxygenotherapy
Oxygen therapy, also referred to as supplemental oxygen, is the use of oxygen as medical treatment. Supplemental oxygen can also refer to the use of oxygen enriched air at altitude. Acute indications for therapy include hypoxemia (low blood oxygen levels), carbon monoxide toxicity and cluster headache. It may also be prophylactically given to maintain blood oxygen levels during the induction of anesthesia. Oxygen therapy is often useful in chronic hypoxemia caused by conditions such as severe COPD or cystic fibrosis. Oxygen can be delivered via nasal cannula, face mask, or endotracheal intubation at normal atmospheric pressure, or in a hyperbaric chamber. It can also be given through bypassing the airway, such as in ECMO therapy. Oxygen is required for normal cellular metabolism. However, excessively high concentrations can result in oxygen toxicity, leading to lung damage and respiratory failure. Higher oxygen concentrations can also increase the risk of airway fires, part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bleeding
Bleeding, hemorrhage, haemorrhage or blood loss, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina, or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume). The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery. Types * Upper head ** Intracranial hemorrhage — bleeding in the skull. ** Cerebral hemorrhage — a type of intracranial hemorrhage, bleeding within the brain tissue itself. ** Intracerebral hemorrhage — bleeding in the brain caused by ...

Spanish Flu
The 1918–1920 flu pandemic, also known as the Great Influenza epidemic or by the common misnomer Spanish flu, was an exceptionally deadly global influenza pandemic caused by the H1N1 subtype of the influenza A virus. The earliest documented case was March 1918 in Kansas, United States, with further cases recorded in France, Germany and the United Kingdom in April. Two years later, nearly a third of the global population, or an estimated 500 million people, had been infected. Estimates of deaths range from 17 million to 50 million, and possibly as high as 100 million, making it the deadliest pandemic in history. The pandemic broke out near the end of World War I, when wartime censors in the belligerent countries suppressed bad news to maintain morale, but newspapers freely reported the outbreak in neutral Spain, creating a false impression of Spain as the epicenter and leading to the "Spanish flu" misnomer. Limited historical epidemiological data make the pandemic' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
