A vaccination is the administration of a vaccine to stimulate the immune system and allow it to develop an immunity to certain infectious agents. Vaccines can prevent or ameliorate an infection or illness and are the most efficient method of preventing infectious disease. Some vaccinations are administered after a patient has contracted a disease, or as a cautionary measure for future prevention. Most vaccinations are administered by way of a hypodermic injection that present a foreign antigen into the patient’s immune system to evoke a response from the immune system. This will, hopefully, allow it to build up an immunity to the disease. Every vaccination is created individually for certain illnesses, so each disease, which is treatable by vaccination, will have a different vaccine specific to that disease.
Each vaccination has been specifically engineered to treat individual infectious pathogens. For example, the influenza vaccine will treat the influenza virus, but not the measles. In that case, a specific measles vaccination would need to be administered. The vaccinations themselves are comprised in some part of a form of the infectious agent itself, usually weakened or killed microbes of the disease itself, or it’s toxins or surface proteins, This is to say that the influenza vaccine contains in some part, the influenza virus itself, but only an amount that has been deemed helpful by medical experts. Some of the common vaccinations include:
Vaccinations are used for the treatment and prevention of certain infectious agents in the body. They can be taken after contracting a disease or before this occurs, as a precautionary measure. Vaccinations are available for such diseases as the chickenpox, hepatitis, the influenza virus, measles, mumps, polio, tetanus, and many more. The vaccine is usually comprised of individual elements of the disease itself that have been altered so that they can be used to prevent that very illness in the immune system of the patient to which it was administered. While there are many diseases that can be treated with vaccines, there are others such as cancer or HIV, which still do not have a vaccine.
Vaccinations Side Effects
Side effects for vaccinations are usually mild and disappear after several days. Allergic reactions to vaccinations are rare, but doctors and their staff are trained to deal with these situations. Most of the time the vaccine will be administered in a doctor’s office by trained medical experts. Because there are so many different vaccines, every individual vaccine has its own list of side effects specific to that individual vaccination. The Center For Disease Control has a list of every side effect associated with every type of vaccine that has been administered for more individualized side effects. Common side effects include:
- Redness/swelling at the injection site
- Low-grade fever
These drugs are associated with patients suffering from a certain illness which can be alleviated by the vaccine that has been specially developed for that disease. Sick people can get vaccinations, but they can also be administered to healthy individuals who are traveling to a certain area where an infectious agent is prominent or those who wish to take a cautionary measure. They are most commonly seen during flu season with the influenza virus vaccine. Vaccinations are not recommended for certain patients who have a severe allergy to any of components of the vaccine being administered. Women who are pregnant or nursing should be cautious about receiving vacations and take every precaution and consult with a doctor before having a vaccination administered. Vaccinations can be used in conjunction with certain antibiotics or instead of them, depending on the particular illness needing treatment.
