- How Covid-19 vaccine work?. This is for information only. 1 – Vaccine prompt the body to develop immunity to a virus without developing an infection.
2 – A vaccine uses an inactive form of the virus whole parts of the virus or just the genetic material of the virus. There are three methods to develop a vaccine:
- Vector vaccine: —- A weakened or inactive virus is used
in this method. Since the virus is not fully functional, it can not be cause of infection. Exposure to it, the immune system has to develop the ability to combat infection, The immune system remembers this method
and uses it in the future. Oxford-AstraZeneca vaccine is
a vector vaccine.
- Protein Subunit vaccine.—- This type of method uses parts, or subunits of the virus. The parts are harmless but they teach the immune system to recognize the proteins of virus and block further infection. The Novavax vaccine is a subunit vaccine.
- mRNA vaccine —– This type of method uses virus genetic material . This type instructs our cells to produce a harmless protein . This protein is similar as virus surface protein. The immune system then recognize the protein and develop a response that protect against further infection. Both the Pfizer-BioNTech and Moderna are mRNA vaccines.
DNA and RNA vaccines carry only the information needed to produce one or more bacterial or viral proteins and can not generate the entire pathogen as other vaccine do , using weakened pathogens. Beside that, generic vaccines activate all components of the immune system to offer better protection than inactivated pathogens and subunit vaccine.
