Jenner observed that the cows had, tits, wounds equal to those caused by smallpox, but milder, and those women who milked cows infected when they were exposed to human virus sickened so milder. He collected the liquid coming out of the wounds of the cows and went over scratches on the arm of a boy. The boy had a slight fever, some minor injuries and had a quick recovery. From there, the scientist took the liquid from the wound of another patient with smallpox and again exposed the boy to the material. Weeks later, when in contact with the smallpox virus, the boy did not get sick. Discovery well was the property immunization. Along with antibiotics, the vaccine was winning doctor who saved more lives and increased the average human longevity in a few decades, to prevent people were affected by diseases that devastated humanity, such as smallpox (the first extinct by natural disease man's hand), yellow fever, typhoid, polio, tetanus, rabies, and many others. How was the early prevention of disease through vaccines in Brazil? Brazil in the nineteenth century, two diseases took the sleep of life of the population and the authorities: yellow fever and smallpox. ABC This species of mosquito is transmitting Yellow Fever and Dengue. Source: United States Agency for International www.wikipedia.org Yellow fever, transmitted by the bite of the mosquito Aedes aegypti, arrived in Brazil in the seventeenth century on ships coming from Africa. The first cases date back to 1685, in Recife, Pernambuco, and 1692, in the city of Salvador, Bahia. In 1849 and 1850, an epidemic forced the Empire to take action. Through a decree, tried to clean up the cities purifying the air. But even so, the yellow fever continued to attack. Do not imagine that the cause of the disease was a mosquito. After 1850, she became endemic in Rio de Janeiro.

Jenner je primijetio da su krave imala, sise, rane jednake onima koje uzrokuje kozice, ali blaže, i one žene koje muzu krave zaražene kad su bili izloženi virusu ljudske pozlilo pa blaži. Skupio je tekućina izlazi iz rane od krava i otišao preko ogrebotina na ruci jednog dječaka. Dječak je imao laganu groznicu, neke manje ozljede, a imao je brz oporavak. Od tamo, znanstvenik je uzeo tekućinu iz rane od drugog pacijenta s velikih boginja i opet izloženo dječaka na materijalu. Nekoliko tjedana kasnije, kada je u kontaktu s virusom velikih boginja, dječak nije razboljeti. Otkriće dobro je nekretnina imunizacije. Uz antibiotike, cjepiva pobjedu liječnika koji je spasio više života i povećao prosječni ljudski dugovječnost u nekoliko desetljeća, da bi se spriječilo ljudi su pogođeni bolestima koje devastirani čovječanstvo, kao što su velike boginje (prva izumrli prirodnim bolesti čovjekova ruka), žute groznice, tifusa, dječje paralize, tetanusa, bjesnoće, i mnogi drugi. Kako je ranije prevenciji bolesti kroz cjepiva u Brazilu? Brazil je u devetnaestom stoljeću, dvije bolesti je san života stanovništva i vlasti: žuta groznica i velike boginje. Abeceda Ova vrsta komarca emitira žuta groznica i denga. Izvor: Američke agencije za međunarodni www.wikipedia.org Žuta groznica, prenosi ugriza komaraca Aedes aegypti , stigao je u Brazilu u sedamnaestom stoljeću na brodovima koji dolaze iz Afrike. Prvi slučajevi datiraju iz 1685, u Recife, Pernambuco, i 1692, u gradu Salvadoru, Bahia. U 1849 i 1850, epidemija prisiljeni Carstvo da poduzme akciju. Kroz dekretom, pokušao očistiti gradove pročišćavanju zraka. Ali čak i tako, žuta groznica i dalje napadaju. Nemojte misliti da je uzrok bolesti bio komaraca. Nakon 1850, ona je postala endemska u Rio de Janeiru.
