@PDevaux_FD Assuming your original single-volume edition disintegrated.

Who remember these manuals which have been useful for so long in the daily work of the lab? We call them the ‘MANIATIS’ the name of one of the co-authors. Although why not the name of one of the other co-authors?

Based on pioneering work by @BAGarvy and Fran Lund that B cells are key antigen presenting cells for Pneumocystis (a common fungal pneumonia in infants), @MNoell_12 figured infants must have anti-fungal IgMs that predict T cell responses. They do! insight.jci.org/articles/view/…

This is why 2nd boosters should be available for all health care workers now. A report on ~30,000 Israeli HCWs indicates 65% lower risk of breakthrough infections during the Omicron wave (4 vs 3 doses) @JAMANetworkOpen

Just published @NEJM
During Omicron, the 2-shot mRNA vaccine effectiveness among >250,000 children age 5 to 11 years old:
vs hospitalizations was very high—83%
vs PCR confirmed infections 65%

Although the handshake and other types of physical contact are gradually returning, they have been on hiatus due to #COVID19. Such changes have already altered the epidemiology of a range of infectious diseases.

Researchers know little about the global diversity and distribution of #soil fungi
To change that - @spununderground - a new nonprofit is funding a global network of subterranean sleuths

What is immune imprinting and why it is important?
A superb explainer

When it comes to #SARSCoV2 and Covid, it's important to keep your eyes on the ball. The ball is BA.5 and here is what we know about it

Second paper showing unfavorable imprinting by omicron, likely meditated by antigen processing...Immune boosting by B.1.1.529 (Omicron) depends on previous SARS-CoV-2 exposure science.org/doi/10.1126/sc…

A new report on Covid reinfections is particularly concerning. I've written about it here erictopol.substack.com/p/a-reinfectio…

T cells could account for slower loss of vaccine protection against severe disease.

A @NatureMedicine paper presents a model that predicts the effectiveness of COVID-19 vaccines against circulating SARS-CoV-2 variants, which could help guide more rapid public health and research responses to new variants of concern. go.nature.com/3O5b8Za

COVID infections are grossly under-reported. On May 31st, the 7-day average was reportedly 1,064, and hospitalizations were at 194, or 18%. Of course, we know that 18% of COVID+ people are not going to hospitals.
English
On Jan 5 the State would have actually had 400,000 cases and reported (accurately?) 1412 hospitalizations (0.35% of cases). All this to say that the current infection rate is probably 194/0.0035=55,000. That's 52 times higher than reported. I'm not going out again for a while.

As we approached the peak of Omicron (Jan 5), 12,757 cases were reported, but the number was likely higher than 10% of the population. Tulane was testing like crazy and getting 12.5 % positive.
