COVID-19 vaccines linked to small increase in menstrual cycle length


25 Jan 2022

At a Glance Women who received COVID-19 vaccines had a less than one-day increase in the length of their menstrual cycles around the time of their doses. The findings suggest that women may have a slightly longer menstrual cycle after COVID-19 vaccination, but the change is temporary and within the range of normal variation.


Deltacron: the story of the variant that wasn’t


21 Jan 2022

News of a ‘super variant’ combining Delta and Omicron spread rapidly last week, but researchers say it never existed and the sequences may have resulted from contamination. On 7 January, virologist Leondios Kostrikis announced on local television that his research group at the University of Cyprus in Nicosia had identified several SARS-CoV-2 genomes that featured elements of both the Delta and Omicron variants.


How One Change to The Coronavirus Spike Influences Infectivity


18 Jan 2022

Since joining NIH, I’ve held a number of different leadership positions. But there is one position that thankfully has remained constant for me: lab chief. I run my own research laboratory at NIH’s National Institute of Dental and Craniofacial Research (NIDCR). My lab studies a biochemical process called O-glycosylation. It’s fundamental to life and fascinating to study. Our cells are often adorned with a variety of carbohydrate sugars. O-glycosylation refers to the biochemical process through which these sugar molecules, either found at the cell surface or secreted, get added to proteins. The presence or absence of these sugars on certain proteins plays fundamental roles in normal tissue development and first-line human immunity. It also is associated with various diseases, including cancer.


Shipments of free coronavirus tests will take at least a week, U.S. officials say

13 Jan 2022

Some people with a weakened immune system can get a fourth dose of the coronavirus vaccine as early as this coming week, according to recommendations from the Centers for Disease Control and Prevention that were updated last week. The C.D.C. endorsed a third dose of the Pfizer-BioNTech and Moderna vaccines for moderately or severely immunocompromised people on Aug. 13, but said this would be considered a part of the primary immunization, not a booster shot.
