First, they take the virus or bacteria and they grow it in a lab. Next they isolate the disease away from the lab materials, which made it grow. Than, they purify the disease, which weakens it. Also, an adjuvant may be added to help the immune system fight off the disease. Finally, everything is mixed up and is shipped out to its final destination.
