When we get sick, our white blood cells fight the harmful germs with special germ killers called antibodies. White cells make antibodies for each particular sickness, so if you have chicken pox, your white blood cells make chicken pox antibodies.

You have become immune to it. However, some people have claimed to have had chicken pox twice; this is probably because they got a very mild version of the disease the first time and did not make enough antibodies.
When we get a cold from a cold virus, our bodies also make antibodies to fight the cold virus, so you can never get a cold from that virus again. But there are more than 200 different kinds of cold viruses, so a new cold virus can enter your body and, if you do not have the "right" antibodies, you can get sick.
