Covid Tests Show the Omicron BA.2 Subvariant Is Gaining Ground in U.S. – Bloomberg

The omicron subvariant BA.2 is continuing to gain ground in the U.S., according to Covid-19 tests sequenced over the last two weeks. Helix, a San Diego-based genomics firm, has been watching the BA.2 variant since it first popped up in the U.S. in early January. Although it was initially slow to take hold, Helix now estimates that 50% to 70% of all Covid cases nationwide are BA.2.

Dr. Fauci says uptick in U.S. cases is likely; It’s ‘no time at all to declare victory’ – MarketWatch

Dr. Anthony Fauci, President Joe Biden’s chief medical adviser, said Sunday that the BA.2 subvariant of the omicron variant of the coronavirus will probably cause an uptick in U.S. cases similar to the one currently being seen in Europe. Fauci, who is also head of the National Institute of Allergy and Infectious Diseases, told ABC’s “This Week” that it is “no time at all to declare victory, because this virus has fooled us before and we really must be prepared for the possibility that we might get another variant, and we don’t want to be caught flat-footed on that.”

How do Omicron-targeted vaccines compare to the original ones? – MedNewsToday

Is there a need for COVID-19 vaccines that are updated to specifically match emerging variants of SARS-CoV-2, or can the original vaccines stand the test of an ever-mutating virus? We looked at the existing data and spoke to three experts to try and answer this question.

Coronavirus (COVID-19) Update: FDA to Hold Advisory Committee Meeting on COVID-19 Vaccines to Discuss Future Boosters – FDA

Today, the U.S. Food and Drug Administration is announcing a virtual meeting of its Vaccines and Related Biological Products Advisory Committee (VRBPAC) on Wed., April 6, to discuss considerations for future COVID-19 vaccine booster doses and the process for selecting specific strains of the SARS-CoV-2 virus for COVID-19 vaccines to address current and emerging variants. Along with the independent experts of the advisory committee, representatives from the U.S. Centers for Disease Control and Prevention and the National Institutes of Health will participate in the meeting.

Clinical Considerations

A Case Of Shrunken Brains: How Covid-19 May Damage Brain Cells – Forbes

Thanks to a new study from the UK we are now beginning to uncover the effects of SARS-CoV-2 infections in the brain. Comparing brain volume before and after individuals were exposed to SARS-CoV-2, this study documents significant cortical gray matter loss, equivalent to nearly 10 years of aging. Gweanaelle Douaud, the study’s first author and Professor at the University of Oxford, says that infected individuals display structural “differences over time above and beyond any potential baseline differences.” Most strikingly, individuals that experienced no or only mild symptoms with Covid-19 displayed specifically significant changes, but cortical damage seems to occur regardless of disease severity, age, sex, or vaccination status. It may be years before the long-term consequences of these structural differences are fully understood.

Research dispels myth that COVID-19 vaccines cause infertility, but misinformation persists – The Conversation

Misinformation about COVID-19 vaccines and fertility has propagated online despite the vaccines’ clear safety profile. Fortunately, those considering having kids can relax when it comes to these crucial shots. These claims lack any realistic basis. As a medical doctor and a COVID-19 genetics researcher, I’d like to discuss what the evidence says.
