RNA vaccines 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.
Protein subunit vaccines include harmless 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.
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.
