Scientists make vaccines by first making the pathogen, or disease-causing microbe, in mass amounts in a laboratory. The pathogens must then be altered to ensure that the disease is not actually triggered. Alterations of these pathogens can be done in different ways. Scientists can weaken the pathogen by growing it over and over and selecting a strand that is less dangerous, take out the part of the pathogen that causes the immune response and use it in the vaccine, or use the toxin that the pathogen makes then inactivate it (Tetanus vaccine). Finally, the treated pathogen is combined with things such as stabilizers and preservatives to then produce the actual vaccine dose.
