Biomedical Research Leads Science’s 2021 Breakthroughs

04 Jan 2022

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 F.D.A. clears booster shots for 12- to 15-year-olds

03 Jan 2022

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.

Expecting a Surge; We look at the latest on Omicron.

16 Dec 2021

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.

Latest on Omicron Variant and COVID-19 Vaccine Protection

14 Dec 2021

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.

Will the Vaccines Stop Omicron? Scientists Are Racing to Find Out.

28 Nov 2021

A “Frankenstein mix” of mutations raises concerns, but the variant may remain vulnerable to current vaccines. If not, revisions will be necessary.

SARS-CoV-2 Vaccines

26 Feb 2021

Shortly after SARS-CoV emerged at the turn of the 21st century, the spike (S) protein (particularly in its prefusion [native] conformation) was identified as the immunodominant antigen of the virus. Evaluation of patients with SARS-CoV-2 revealed that binding and neutralizing antibodies primarily target the receptor-binding domain of the S1 subunit.

SARS-CoV-2 Variants of Concern in the United States—Challenges and Opportunities

17 Feb 2021

. SARS-CoV-2, like other RNA viruses, constantly changes through mutation, with new variants occurring over time. Generally, when new variants become more common, they do so because of some selective advantage to the virus.

The US Regulatory System and COVID-19 Vaccines The Importance of a Strong and Capable FDA

15 Feb 2021

For many in public health and medicine, the coronavirus disease 2019 (COVID-19) pandemic in the US has been a frustrating journey from one disappointment to the next: late access to testing, insufficient staff and inadequate funding for contact tracing, jumbled communications, and, at the end of 2020, a chaotic launch of vaccination efforts.

COVID-19 Vaccination in Pregnant and Lactating Women

08 Feb 2021

Pregnant women with severe or critical coronavirus disease 2019 (COVID-19) infection are at increased risk for preterm birth and pregnancy loss.

Durability of Responses after SARS-CoV-2 mRNA-1273 Vaccination

04 Feb 2021

We recently reported the results of a phase 1 trial of a messenger RNA vaccine, mRNA-1273, to prevent infection with SARS-CoV-2; those interim results covered a period of 57 days after the first vaccination.
