COVID-19 Vaccines and Types
The COVID-19 vaccine is a biotech product that aims to provide acquired immunity against the disease known as COVID-19.
Vaccine Types Under Development for COVID-19
Considered one of the easiest vectors to design, human adenoviruses have therefore become very popular in the industry. The purpose of these vectors is to carry genetic material from another virus to a cell. The gene that causes infection is removed from adenoviruses, and then the genetic material (a gene encoding the spike protein) obtained from the COVID-19 virus is added. The function of the viral vector is to serve as a distribution system. The added gene is safe for the body, but still trigger the immune system enough where it produces antibodies that protect us from infection. Encountering S proteins on the surfaces of your cells, your immune system will create antibodies and respond with defensive white blood cells. If you have been infected with the COVID-19 virus, you gained antibodies that will fight the virus. Viral vector vaccines cannot cause you to become infected with the COVID-19 virus or viral vector virus. Additionally, the genetic material taken will not be part of your DNA.

Vaccines containing inactivated viruses that do not cause disease but instead cause a sufficient immune response.
Vaccines that contain attenuated virus that do not cause disease but produce a sufficient immune response.
By using protein fragments that mimic the structure of the COVID-19 virus, it generates a sufficient immune response.
m-RNA and DNA vaccines: An approach that uses genetically engineered RNA and DNA fragments to produce proteins that induce a safe immune response on their own.
The m-RNA Vaccine uses genetically engineered m-RNA to instruct your cells on how to make a harmless piece of S protein that is also found on the surface of the COVID-19 virus. After vaccination, your immune cells begin to make S protein fragments and display them on cell surfaces. This causes your body to create antibodies. If you become infected with the COVID-19 virus, these antibodies will know how to fight the virus.
