what’s an antibodies

specialized protein made by your immune system to identify and destroy foreign invaders like bacteria and viruses.

list the key characteristics of viruses

contain genetic material, contains no cells(made up of some proteins), needs a host in order to reproduce

how do vaccines work

-injected with a dead or weakened verizon of the actual virus

• once injected your immune system will react and create antibodies to this virus.

• your body then recognizes this pathogen the next time it is encountered

• you do this to prepare your body.

antibiotic resistance
