AP BIOLOGY

Detailed explanation-1: -Similarly, these vaccines will not cause rapid antigen tests to be positive, since the proteins produced following vaccination are not expressed in the respiratory (i.e., nasal) tract, which is sampled for Covid-19 PCR or antigen testing.

Detailed explanation-2: -When you get a vaccine, your immune system responds to the vaccine the same way it would to the real germ. It: Recognizes the germ in the vaccine as being foreign. Responds by making antibodies to the germ in the vaccine, just as it would for the real germ.

Detailed explanation-3: -All vaccines contain an active component (the antigen) which generates an immune response, or the blueprint for making the active component. The antigen may be a small part of the disease-causing organism, like a protein or sugar, or it may be the whole organism in a weakened or inactive form.

Detailed explanation-4: -Vaccines contain antigens that stimulate the immune system to produce an immune response that is often similar to that produced by the natural infection. With vaccination, however, the recipient is not subjected to the disease and its potential complications.
