Feeling sick can be especially concerning these days. Could your sniffles be caused by COVID-19? Or the flu? A cold? Or maybe allergies? Determining the cause of an illness can be tricky because many share some symptoms. They can leave you sniffling, coughing, and feeling tired. But there are important differences.
Breakthrough of the Year: AI-Powered Predictions of Protein Structure The biochemist Christian Anfinsen, who had a distinguished career at NIH, shared the 1972 Nobel Prize in Chemistry, for work suggesting that the biochemical interactions among the amino acid building blocks of proteins were responsible for pulling them into the final shapes that are essential to their functions. In his Nobel acceptance speech, Anfinsen also made a bold prediction: one day it would be possible to determine the three-dimensional structure of any protein based on its amino acid sequence alone. Now, with advances in applying artificial intelligence to solve biological problems—Anfinsen’s bold prediction has been realized.
The Food and Drug Administration on Monday authorized booster doses of Pfizer-BioNTech’s coronavirus vaccine for 12- to 15-year-olds, a group that became eligible for initial shots in May.
Get ready for the Omicron surge, and take it seriously. But remember that the vaccines appear to provide strong protection against what matters most: severe Covid illnesses. That’s my reading of experts’ reactions to the latest developments on the Omicron variant. Today, I will walk through them.
There’s been great concern about the new Omicron variant of SARS-CoV-2, the coronavirus that causes COVID-19. A major reason is Omicron has accumulated over 50 mutations, including about 30 in the spike protein, the part of the coronavirus that mRNA vaccines teach our immune systems to attack. All of these genetic changes raise the possibility that Omicron could cause breakthrough infections in people who’ve already received a Pfizer or Moderna mRNA vaccine.
MINNEAPOLIS — Gloria Torres-Herbeck gets the flu vaccine every year, but the 53-year-old teacher in Rochester, Minnesota, isn’t yet convinced she wants to be first in line for a potential COVID-19 vaccine.
