Antibiotic A substance that inhibits the growth of bacteria.
Ring Vaccination Administering a vaccine only to people in close contact with the infected person.
Pathogen A microbe capable of causing disease, consists of 3% of microbes.
Vaccine Prep made from killed or weakened pathogens that stimulate production of antibodies protecting individuals, can be swallowed or injected.
Immunization Processes that pormote the body's immunity against specific disease.
Polio A highly infectious disease that mainly affects children. At its worse, it can cause paralysis and deformity. Through vaccination, it is preventable.
