Elderly people cry over Covid booster and congratulate SUS and Pasteur: “Vaccines are humanity’s greatest invention” | Sao Paulo

“I am very happy to be in Brazil and to have this SUS [Sistema Único de Saúde]. Today is my day for the third dose, we just have to congratulate the SUS, and congratulate the vaccine, invented by Louis Pasteur, in 1850,” he said.

“I’ve been doing this for 40 years, and I’ve been taking the whole vaccine, because the vaccine is the greatest invention of mankind,” he adds.

world louis Pasteur played a key role in the production of vaccines. Pasteur’s experience with vaccines came when he was studying fowl cholera, a disease caused by Pasteurella maltocida. One of Pasteur’s assistants went on vacation and accidentally left a forgotten culture in the lab. When he returned, the aging culture was no longer effective in infecting the birds. Then Pasteur conducted a second experiment, in which these chickens were infected with a new virulent culture (which causes disease). To his surprise, the chicken survived the challenge.

In 1881, Pasteur also worked on the same principle to produce the anthrax bacterium (Bacillus anthracis), cultivating it at high temperatures. This heat-reducing bacteria has been used as a vaccine to protect sheep from challenging anthrax bacteria. With this Pasteur vaccine, in 1881, the mortality rate of sheep was drastically reduced to 0.34% and cattle to 1%.

Finally, in 1885, Pasteur began his studies of rabies, using the dry spinal cords of rabbits and dogs infected with the virus as a material to prepare the vaccine for which he was famous.
