WHAT ARE VACCINES
Vaccines are biologically prepared products that protects people from particular disease. What are vaccines? Vaccines are actually protein based viruses or antibodies that are injected into the body. Antigens are contained within these proteins, which helps them to be able to affect the immune system.
What are vaccines made of
Thay are made from weakened or killed microorganisms, its toxins, surface proteins or any other microbe products.
When vaccines are injected into a body, then body recognises it as foreign particle and develop antibodies against that particular microbe as vaccines are prepared from weakened or killed microbes.
Some vaccines are made of synthetic components, and other are composed of live microorganisms. Live vaccines are more effective because they contain the exact proteins and antibodies that your body requires for successful treatment. There are two main types of mrna vaccines: live and non-live. Both have proven to be extremely efficient in fighting infectious agents.
Immune system develops memory against that particular microbe, so that it can easily recognized when this microbe again encounter the body.
Vaccines are tested and safe to use. They are used to act as an antigen and do not induce disease.
Sometimes booster dose is also given which means re-exposure of the antigen. It is used to enhance immunity level as memory against that particular antigen may be declined through time.
Vaccine and Immunization
You may have heard the words “vaccine” and “immunization” used in the same sentence but you really have no idea what the differences are. The terms vaccine and immunization are often used interchangeably though they are not always used in the same way. The difference between these two terms is basically that a vaccine offers an individual with temporary protection against an infection while an immunization offers a person with a longer term protection against the infection. This is the difference between having the flu and having the shot. Basically, a vaccination prevents illness while an immunization helps you fight off illness.
A vaccine is actually a purified form of bacteria or virus that provides temporary protection to an individual against a specific infectious agent. Generally, a vaccine contains one or more components which are designed to stimulate the immune system to produce antibodies (also known as antibody titers). The antibodies are then directed against a specific strain of bacteria or virus so as to produce antigens – small globular structures that bind together with the antigens – that are then bound to the surface of a cell.
What are vaccines with examples
1. Mhra vaccines
Mhra vaccines are made to prevent a new kind of herpes virus from spreading among the community. Although it is relatively new compared to other varieties of herpes like Herpes Simplex Virus and Varicella-Zoster Virus, mhra is spreading at a fast rate and needs a vaccine in order to control its spread. Mhra is a highly contagious form of herpes and it can cause serious complications in individuals who are not immune to this type of illness. Mhra can be sexually transmitted, passed on from one person to another during sex, and it can also be contracted through a blood transfusion.
2. Pox vaccine
pox is another type of vaccines that are used. Like measles, it too is caused by a virus but it too is easily spread among communities by those who have a working knowledge of how to deal with the problem. Unlike measles, however, a single dose of the pustularia vaccine is usually sufficient to protect a person. An individual who has never had this disease before is allowed to be vaccinated if they show symptoms of the illness within three days of being administered the shot. However, no person, including children, can be vaccinated if they have already received a varicella-zoster vaccine within the last five years.
3. Mumps vaccine
Mumps is an extremely common disease that is believed to affect as many as one million Americans each year. The mumps part of the name comes from the fact that the disease seems to affect mostly children. An outbreak of mumps is usually linked to the spread of what are called “kissing disease” which often is spread this way. Those who have received one or more doses of mumps vaccines and who believe they may have been infected with mumps should contact their local health department for further information about the disease.
Types of vaccines
Some vaccines also contain germs or microorganisms that are designed to induce the immune system to fight off other harmful bacteria and viruses. These types of vaccines help to protect against diseases like measles, shingles, and even influenza. Some types of these vaccines require multiple shots over time. For example, a series of injections is necessary after receiving a single dose of a Zoster vaccine. Another example would be the development of vaccines that stimulate the immune system to fight off the Lassa fever virus.
There are many different types of vaccines available today. Some have been licensed for use for specific diseases and/or circumstances. For example, there is a vaccine that is used for what are known as varicella-zoster viruses. This vaccine has been shown to be effective in preventing what are known as herpes outbreaks. However, the vaccine has not been proven to be effective in what are called vaccine-preventable diseases. These diseases include diphtheria, pertussis, tetanus, hepatitis B, poliovirus, and rotavirus.
