How does a vaccine work? how does a vaccine work?

Answer and Explanation:

The person who answered before me is correct.

Vaccines train your immune system to recognize certain bad bacteriums, viruses, and other micro-organisms that can cause disease so they can (at least attempt to) fight it off.

When doctors inject these antigens into us, (which is something that induces an immune response in the body by producing antibodies) our immune systems can learn how to recognize these foreign, hostile invaders and fight them off.

Plus, if we get a certain disease again, these antigens will remember and most likely fight it off better than before.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
