Did you know that when your immune system knows the antigen of a disease, you are immune to this disease? Before vaccines exist, the only way to become immune to a disease was sick and, with luck, surviving her. This is called "naturally acquired immunity." Vaccines provide "artificially acquired immunity," are an easier and less risky to boost immunity. Vaccines are among the few drugs that can prevent the occurrence of a disease rather than cure it after it occurs. Vaccines not only protect you but also protect the people around you. With your immune system activated by the vaccine, to come into contact with the causative agent, you are infected for a short period of time, or even abort the infection, thus preventing the transmission of disease. Similarly, when other people are vaccinated, the chance of transmitting a disease it is smaller. Therefore, vaccines protect not only one person but the whole community. When a certain proportion of people are vaccinated against a disease, the whole group becomes more protected, even those who did not take the vaccine. This "coverage" gives "community immunity". Hence the importance of you participate in immunization campaigns. Vaccines: how would humanity without this aid for the defense of our body? After this study, you can already answer how would humanity without the aid of vaccines for the defense of our body?

Jeste li znali da kada vaš imunološki sustav zna antigena bolesti, da su imuni na tu bolest? Prije cjepiva postoje, jedini način da postanu imuni na bolesti bio bolestan i, uz malo sreće, joj preživljavanje. To se zove "prirodno stekao imunitet." Cjepiva osigurati "umjetno stečenog imuniteta," su lakše i manje rizično za jačanje imuniteta. Cjepiva su među nekoliko lijekova koji mogu spriječiti pojavu bolesti, a ne ga liječiti, nakon što se događa. Cjepiva ne samo vas zaštititi, ali i zaštititi ljude oko vas. Uz vaš imunološki sustav aktiviran od cjepiva, kako bi došli u dodir s uzročnika, što su zaraženi kratkom vremenskom razdoblju, ili čak prekinuti infekcije, čime se sprečava prijenos bolesti. Isto tako, kada su drugi ljudi su cijepljeni, šanse za prijenos bolesti je manja. Stoga, cjepiva štite ne samo jednu osobu nego cijelu zajednicu. Kada se određeni postotak ljudi su cijepljeni protiv bolesti, cijela grupa postaje zaštićeni, čak i oni koji nisu uzeti cjepivo. Ovaj "pokrivenost" daje "zajednici imunitet". Zato je važno od vas sudjelovati u kampanjama cijepljenja. Cjepiva: Kako bi čovječanstvo bez te potpore za obranu našeg tijela? Nakon ovog istraživanja, već možete odgovoriti kako bi čovječanstvo bez pomoći cjepiva za obranu našeg tijela?
