Health radar: Nobel Prize for Medicine celebrates Covid-19 vaccines


Hungarian Katalin Karikó and American Drew Weissman made history by helping to save millions and millions of lives in pandemic.

Thanks to his discoveries in the laboratory, the result of years of work (sometimes discredited in academia), it was possible to develop the messenger RNA vaccinesessential for the containment and prevention of Covid-19.

The duo, working at the University of Pennsylvania, in the United States, discovered a way to introduce specific RNAs — small particles that give genetic instructions to cells — without causing undesirable reactions in the body.

The method was used to create the first vaccines of this type, decisive in controlling the health crisis, and opened an avenue for new vaccines and therapies against diseases such as cancer. A feat recognized by the Nobel Prize in Physiology or Medicine in this year. Science that excites!

One sentence: Boris Groys

(Illustration: PriWi/HEALTH is Vital)

“A healthy person’s decision to ignore all reasonable advice and take the risk of death is admired by our society. Sick people are supposed to choose life, but healthy people are encouraged to choose death. In a war, this becomes obvious. But we also admire the intense work effort that can harm the Worker’s health. And we admire those who practice sports and adventures that can lead to death (…) What is favorable to the symbolic body can ruin the physical body. Improving social status (…) often means investing energy in something that ruins our health.”

Boris Groys, German philosopher, in the book Philosophy of Care (Âyiné)
