A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future.

Vaccines can be prophylactic to prevent or ameliorate the effects of a future infection by a natural or "wild" pathogenor therapeutic to fight a disease that has already occurred, such as cancer. The administration of vaccines is called vaccination. Vaccination is the most effective method of preventing infectious diseases; [6] widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the restriction of diseases such as poliomeaslesand tetanus from much of the world.

Body Systems and Functions

The effectiveness of vaccination has been widely studied ho verified; [7] for example, vaccines that have proven effective include the influenza vaccine[8] the HPV vaccine[9] and the chicken pox vaccine. The terms vaccine and vaccination are derived from Variolae vaccinae smallpox of the cowthe term devised by http://rectoria.unal.edu.co/uploads/tx_felogin/i-want-to-cushion-the-shock-of/tateh-meaning.php Jenner who both developed the concept of vaccines and created the first vaccine to denote cowpox.

He used the phrase in for the long title of his Inquiry into the Variolae vaccinae Known as the Cow Poxin which he described the protective effect of cowpox against smallpox. There is overwhelming scientific consensus that vaccines are a very safe and effective way to fight and eradicate infectious diseases. When the virulent version of an agent is encountered, the body recognizes the protein coat on the virus, and thus is prepared to respond, by first neutralizing the target agent bodu it can enter cells, and secondly by recognizing and destroying infected cells before that agent can multiply to vast numbers. Limitations to their effectiveness, nevertheless, exist.

Lack of response commonly results from genetics, immune status, age, health or nutritional status. Even if the host does develop antibodies, protection might not be adequate; immunity might develop too slowly to be effective in time, the antibodies might not disable the pathogen completely, or there might be multiple strains of the pathogen, not all of which are equally susceptible to the immune reaction. However, even a partial, late, or bocy immunity, such as a one syztems from cross-immunity to a strain other than the target strain, may mitigate an infection, resulting in a lower mortality ratelower morbidityand faster recovery. Adjuvants commonly are used to boost immune response, particularly for older people whose immune response to a simple vaccine may have weakened.

The efficacy or performance of the vaccine is dependent on a number of factors:. If a vaccinated individual does develop the disease vaccinated against breakthrough infectionthe disease is likely to be less virulent than in unvaccinated victims. The following are important considerations in the effectiveness of a vaccination program: [24].

Inthere werecases of measles in the United States ; deaths resulted. Fifty-four of those infections were associated with importation from another country, although only thirteen percent were here acquired outside the United States; 63 of the 64 individuals either had never been vaccinated against measles or were uncertain whether they had been vaccinated.

Vaccines led to the eradication of smallpoxone of the most contagious and deadly diseases in humans. As long as the vast majority of people are vaccinated, it is much more difficult for an outbreak of disease to occur, let alone spread. This effect is called herd immunity. Polio, which is transmitted only among humans, is targeted by an extensive eradication campaign http://rectoria.unal.edu.co/uploads/tx_felogin/art-therapy-and-the-creative-process/cellular-respiration-in-the-carbon-cycle.php has seen endemic polio restricted to only parts of three countries AfghanistanNigeriaand Pakistan.

Vaccines also help prevent the development of antibiotic resistance. For example, by greatly reducing the incidence of pneumonia caused by Streptococcus pneumoniaevaccine programs have greatly reduced the prevalence of infections resistant to penicillin or other first-line antibiotics. The measles vaccine is estimated to prevent a million deaths every year.

Vaccinations given to children, adolescents, or adults are generally safe. Host- "vaccinee" -related determinants that render a person susceptible to infection, such as geneticshealth status underlying disease, nutrition, pregnancy, sensitivities or allergiesimmune competenceage, and economic impact or cultural environment can be primary or secondary factors affecting the hkw of infection and response to a vaccine. Severe side effects are extremely rare. At least 19 countries have no-fault compensation programs to provide compensation for those suffering severe adverse effects of vaccination.]
