Injectable vaccines also require trained healthcare professionals to disseminate. Currently, three different influenza strains circulate worldwide: One should, therefore, make sure that such areas are sanitized using disinfectants. Most people who get the flu recover completely in 1 to 2 weeks, but some people develop serious and potentially lifethreatening medical complications, such as pneumonia.
The nasal spray should never be administered to women who are pregnant. Influenza Vaccine Much of the illness and death caused by influenza can be prevented by annual influenza vaccination.
Statistics reveal that approximately 3, to 50, people die each year from flu Flu. Vaccine efficacy also varies from one person to another.
This vaccine is made with viruses that can confer immunity but do not cause classic influenza symptoms. The term "stomach flu" is a misnomer that is sometimes used to describe gastrointestinal illnesses caused by other microorganisms. The virus that reappeared in was virtually identical to an A H1N1 virus that circulated in The fact that influenza viruses continually change is one of the reasons vaccine must be taken every year.
These highrisk groups include all people aged 65 years or older and people of any age with chronic diseases of the heart, lung or kidneys, diabetes, immunosuppression, or severe forms of anemia.
Expression of Hepatitis B surface antigen in transgenic banana plants and NT- I cell line of tobacco. The free Biology research paper Influenza essay presented on this page should not be viewed as a sample of our on-line writing service.
Typical clinical features of influenza include fever usually oF to oF in adults and often even higher in children and respiratory symptoms, such as cough, sore throat, runny or stuffy nose, as well as headache, muscle aches, and often extreme fatigue. The fact that the elderly appear to have natural protection against current A H1N1 viruses probably explains the low mortality associated with recent epidemics in which this subtype was the predominant strain.
These side effects are most likely to occur in children who have not been exposed to influenza virus in the past. I offer to provide assistance to ensure that my recommendations are implemented successfully in case they are adopted. Nevertheless, some older people remember earlier influenza vaccines that did, in fact, produce more unpleasant side effects.
In the elderly and those with certain chronic medical conditions, the vaccine is often less effective in preventing illness than in reducing the severity of illness and the risk of serious complications and death. How to do a research paper on Prevention of flu Published under category: The older antibody can, however, provide partial protection against reinfection.
It takes about 1 to 2 weeks after vaccination for antibody against influenza to develop and provide protection. In that case, assignment writing service will do a paper on flu for you. One is a series of mutations that occur over time and cause a gradual evolution of the virus.
However, it can get serious when one has health conditions like heart disease, diabetes, asthma or a weakened immune system. This results in a worldwide epidemic, called a pandemic. The health experts note that the flu vaccine is not percent effective hence people should also take measures that help in reducing the spread of the virus WebMD, n.
Type A viruses are divided into subtypes based on differences in two viral proteins called the hemagglutinin H and the neuraminidase N. Efforts to control the impact of influenza are aimed at types A and B, and the remainder of this discussion will be devoted only to these two types.
The Flu problem Seasonal flu is an illness that is caused by three types of viruses that include influenza A, B and C. It periodically caused large epidemics, but never on the scale of the pandemic. Influenza types A and B are responsible for epidemics of respiratory illness that occur almost every winter and are often associated with increased rates for hospitalization and death.
Each year the vaccine is updated to include the most current influenza virus strains. Type A viruses undergo both kinds of changes; influenza type B viruses change only by the more gradual process of antigenic drift.
It is administered annually before the start of the winter season. Of the influenza viruses currently in worldwide circulation, A H3N2 still has the most severe overall impact. When antigenic drift results in the circulating virus becoming different from the vaccine strain, overall efficacy may be reduced, especially in preventing illness, but the vaccine is still likely to lessen the severity of the illness and to prevent complications and death.
During this century, pandemics occurred in, andeach of which resulted in large numbers of deaths, as noted below.My co-bloggers and I over at Science-Based Medicine have written at length about vaccines in general, influenza, the influenza vaccine, and the antivaccination movement.
Here are links to some of my extensively referenced essays on influenza and vaccines. What is the Influenza Vaccine? There are many different kinds of vaccinations for the flu such as the egg-based flu vaccine, the cell-based flu vaccine, and the recombinant flu vaccine. The one that people receive from doctors and physicians is the egg-based flu vaccine, this vaccine is actually the most common way that the flu vaccine are made.
Influenza Vaccines - Influenza is a major cause of worldwide morbidity and mortality every year, although Influenza Vaccines (i.e., flu shots) is a effective way to decrease the chance of morbidity and mortality caused by influenza.
Nov 28, · This meant that full vaccination is necessary to optimally protect children of this age group from Influenza (Shueler et al.). The results are consistent with those of other evaluative studies on children through randomized, controlled trials for efficacy and observational studies for effectiveness (Shueler et al., ).
Flu vaccines are available as Flu shot of trivalent inactivated or killed virus (TIV) or Live Attenuated Influenza Vaccine (LAIV) as nasal spray. However, it is impossible to prevent influenza by one time vaccination because Influenza viruses undergo changes from year to year and develop resistance making previously available vaccines ineffective.
