antigen

The new vaccine combines the traditional pertussis antigens with an innovative adjuvant called T-vant, which boosts the body's immune response specifically in the respiratory tract.

The kits offered by the federal government contain antigen tests, which look to see whether a sample taken from your nostrils contains a protein that binds to the coronavirus’ RNA.

Each contains different antigens and antibodies, meaning that receiving blood from the wrong group can be life-threatening.

Thus IFN-gamma responses are marker of vaccine candidate antigens and efficacy.

Then, they also added molecules and antigens common to cancer cells to "teach" T-cells what to look for.
