Vaccines 101...
Almost everyone has had a vaccine. Since the day you were born, doctors inject you with vaccines to protect you from said, "infections" and "diseases". The misconceptions regular people have about vaccines is that they are a said, "cure" for a certain infection or disease, and when in the body, helps prevent you from getting it. This theory is incorrect. In this article, we will be going over what vaccines are, and how they work.
What Are Vaccines?
Let's start simple...
Vaccines or vaccinations are simply an injection that is used to stimulate your body's immune response against diseases or infections. In simpler terms, a vaccine prepares or trains your body to fight an infection or disease.
Vaccines usually contain antigens, weak and/or inactive parts of an organism which trigger an immune response in your system. These antigens aren't the infectious, contagious part of the virus. So don't believe that for a flu-shot you are getting injected with the contagious and dangerous flu, this is absolutely incorrect.
Vaccines are usually administered in needle injections, but can be done in other fashions.
2 Other Main Vaccine-Types:
1
Messenger-RNA Vaccines (mRNA)
Messenger RNA Vaccines are completely different than a regular vaccine. In a regular vaccine the body is injected with an antigen, where the body will create antibodies so that it can fight the real infection or disease. However with a mRNA vaccine, the cells are instructed to create it's
own protein to trigger an immune response in case of an infection. This is another safe vaccination form.
2
Live-Attenuated Vaccines
Live-Attenuated Vaccines are quite similar to regular vaccines, in the way that they both use a weakened form of the virus, however this virus can still grow and replicate, but not infect cells, while regular vaccines viruses have been genetically destroyed and also cannot infect other cells.
This is also a safe vaccination form.
