Vaccines and Immunization

Vaccines

A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. Vaccines play an important role in keeping us healthy. They protect us from serious and sometimes deadly diseases like haemophilus influenzae type b (Hib) and measles. The challenge in immunogenic development consists in making a immunogen sturdy enough to chase away infection while not creating the individual seriously unwell. Thereto finish, researchers have devised differing types of vaccines.
