What is an oral vaccine?

Vaccine is a type of medical treatment that is made of inactivated or dead microbes causing diseases such as viruses. The vaccine can be introduced in two ways: injection or as an oral vaccine. The oral vaccine is one that is used by mouth instead of being injected directly into the blood. The aim of all vaccines, whether injecting or as an oral vaccine, is to trigger the body's immune system without actually having a disease. It is a way of immunization or protection of the body from acquiring the disease. Every day we come into contact with the diseases causing the disease, but we do not end up with the disease itself. This may be due to a number of reasons, including physical, chemical and cellular defense of the body that either prevents microorganisms from entering the body, or spread if they can get.

Any molecule that is recognized by the bodyIt is referred to as antigen . White blood cells called lymphocytes are one type of cell found in the immune system. These cells create a type of protein molecule called antibody that counteracts a particular antigen. Antigens and antibodies are highly specific to themselves, so the antibody is only excreted if it encounters the appropriate antigen in the body.

When he first meets the antigen, it takes some time to produce antibodies. Sometimes it can take up to several weeks to get enough antibodies to destroy all antigens. As soon as the antigen meets, it is in each other time in the body, the reaction is much faster, with antibodies to produce the larger numbers and much faster.

This is the basis of vaccines; They represent an antigen into the body without endangering a person. As an antigen occurs in the body, the immune system creates the appropriate antibodies. This means that if the vaccinated individual meetsWith antigens of the disease, the immune response will be immediate, which does not allow individuals to infect the disease.

One of the most common examples of oral vaccine is the palsy vaccine. This vaccine is an example of a lively attenuated vaccine, which means that the virus that causes that palsy actually live, but has been changed so that it is less virulent or capable of causing disease. This oral vaccine was created to produce immunity for all three viruses that cause palsy. Because it is a living vaccine, it is assumed that immunity is throughout life.
