What is a vaccine and how does it work?
Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself.
How does the immune system respond to vaccines?
Your immune system reacts to the vaccine in a similar way that it would if it were being invaded by the disease — by making antibodies. The antibodies destroy the vaccine germs just as they would the disease germs — like a training exercise. Then they stay in your body, giving you immunity.
What does the Covid vaccine contain?
mRNA – Also known as messenger ribonucleic acid, mRNA is the only active ingredient in the vaccine. The mRNA molecules contain the genetic material that provide instructions for our body on how to make a viral protein that triggers an immune response within our bodies.
What type of immunity would a vaccine activate?
Vaccines provide active immunity to disease. Vaccines do not make you sick, but they can trick your body into believing it has a disease, so it can fight the disease.
