 ===== Genetic Vaccines ===== ===== Genetic Vaccines =====
 [[Genetic vaccine]]s, including [[mRNA vaccine]]s, contain material from the virus that causes COVID-19 that gives our cells instructions for how to make a harmless protein that is unique to the virus. After our cells make copies of the protein, they destroy the genetic material from the vaccine. Our bodies recognize that the protein should not be there and build T-lymphocytes and B-lymphocytes that will remember how to fight the virus that causes COVID-19 if we are infected in the future. [[Genetic vaccine]]s, including [[mRNA vaccine]]s, contain material from the virus that causes COVID-19 that gives our cells instructions for how to make a harmless protein that is unique to the virus.

 [[:Protein subunit vaccine]] include pieces (proteins) of the virus that causes COVID-19 instead of the entire germ. Once vaccinated, our bodies recognize that the protein should not be there and build T-lymphocytes and antibodies that will remember how to fight the virus that causes COVID-19 if we are infected in the future. [[:Protein subunit vaccine]] include pieces (proteins) of the virus that causes COVID-19 instead of the entire germ.

 ===== Vector Vaccines ===== ===== Vector Vaccines =====
 [[:Vector vaccines]] contain a modified version of a different virus than the one that causes COVID-19. Inside the shell of the modified virus, there is material from the virus that causes COVID-19. This is called a “viral vector.” Once the viral vector is inside our cells, the genetic material gives cells instructions to make a protein that is unique to the virus that causes COVID-19. Using these instructions, our cells make copies of the protein. This prompts our bodies to build T-lymphocytes and B-lymphocytes that will remember how to fight that virus if we are infected in the future. [[:Vector vaccines]] contain a modified version of a different virus than the one that causes COVID-19.

 [[:Live attenuated virus vaccine]]s use an weakened, typically with chemicals, heat or radiation, version of the virus that cause a disease. This is a proven technology used for previous vaccines.  [[:Live attenuated virus vaccine]]s use an weakened, typically with chemicals, heat or radiation, version of the virus that cause a disease.
