antigens

Unfortunately for all of us, the immune system has no concept of the innocuous nature of harmless antigens.

For many vaccines, antigens for eliciting an antibody response to several diseases are combined into one formulation.

Although, with three different antigens per dose of vaccine, that gets you back to 3 eggs produce 3 doses.

To slow absorption of injected antigens (e.g., insect stings), a tourniquet may be placed proximal to the injection site.

The malaria antigens, that trigger the antibody response, are extremely variable and allow the malaria parasites to evade the body's immune system.

The problem is in inducing the immune response, usually these antigens don't mount strong immune responses so the attack is too slow relative to the rate that cancer cells divide and spread.

Give your body a little bit of non-infectious virus so it can build appropriate antigens before you encounter it in real life.

You either need bespoke antigens that will react to the presence of specific pathogens, or primers and other components for DNA/RNA based tests.

Wikipedia right now says: Acellular pertussis vaccine (aP) with three or more antigens prevents around 85% of typical whooping cough cases in children.

The body can tolerate millions of antigens being presented to it simultaneously.

Recently I've seen some articles that they've figured out at least partly how the immune system learns to ignore antigens.

Other important factors might include novel protein antigens and small molecules we have not co-evolved with.

The "ap" in DTaP vaccine means "acellular Pertussis", which means it uses antigens of the pertussis pathogen rather than whole cells.

Actually, it depends on the vaccine, and even killed virus strains aren't going to present all the antigens that a "healthy" or attenuated vaccine virus does.
