• Because some diseases are too severe for our immune system.
• Because adaptive immunity takes days to weeks to initiate a response and sometimes it is too late.
• Because some people are immune deficient or have weak immune systems.
• All of the above

• Physical barriers

• White blood cells

• Blood plasma

• Red blood cells
