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 micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins.
Definition. DTP vaccine confers immunity to diphtheria, tetanus, and pertussis. The vaccine used in the United States is actually multiple diphtheria and tetanus toxoids combined with acellular pertussis (DTaP).he original vaccine, which as of 2004 was still used in other parts of the world, contains whole cells of Bordatella pertussis, the organism that causes pertussis, better known as whooping cough. The whole cell vaccine is more likely to cause adverse effects and does not provide any greater immunity.
