A report from two CDC scientists was published online today in JAMA Insights which describes in detail 21 cases of anaphylaxis that were reported to the US Vaccine Adverse Events Reporting System between December 14-23, 2020. This corresponds to a very low rate of 11.1 cases of anaphylaxis per million doses administered. 17 of these…
I continue to urge all my patients to get vaccinated as soon as possible. Benefits far outweigh the risk.

What Scientists Are Learning About Covid-19 Using the Nation’s Blood Supply — Smithsonian Magazine
Labs and blood banks collect millions of blood samples each month, offering a distinctive source of data on the disease…
Their data so far suggest that a lot of people have had Covid-19 without ever receiving a diagnosis. Confirmed case counts suggest that almost 7 percent of people in the U.S. have had the virus. Data from the arm of the study looking at blood from clinical laboratory tests from all 50 states, the District of Columbia, and Puerto Rico found rates of antibody positivity that at times ranged from under 1 percent in some states to 23 percent in New York…
Some experts have reservations about the use of blood donation data to estimate the prevalence of Covid-19. “The problem with blood donors — and this is also supported by evidence from other epidemics like HIV, and previous pandemics — is that blood donors are weird people” from a statistical point of view, said Gideon Meyerowitz-Katz, an epidemiologist at the University of Wollongong. “And blood donors who give blood during a pandemic, when the country is in lockdown in particular, are very weird people.”

ACE2-interacting domain of SARS-CoV-2
In a study published in the Journal of Neuroimmune Pharmacology, mouse models with COVID-19 showed positive results when a small peptide was introduced nasally. The peptide proved effective in reducing fever, protecting the lungs, improving heart function and reversing cytokine storm — a condition in which an infection triggers the immune system to flood the bloodstream with inflammatory proteins. The researchers also report success in preventing the disease from progression.

Our neighbor Dr. Arlan Richardson at https://nathanshockcenters.org/oklahoma part of the University of Oklahoma Health Sciences Center knows a lot about mice. I’ll have to ask him what he thinks of the potential of this peptide for human use.
American Democracy is in No Imminent Danger — Benjamin Studebaker
In 2014, I finished an MA thesis at the University of Chicago. In that thesis, I argued that as economic inequality increased, American politics would return to the sharp political divisions of the 1930s, with both left-wing and right-wing radical movements popping up all over the place. Recently, I finished a PhD thesis at the […]

Poor gut health is Associated With Severe COVID-19
In a review published this week in mBio, microbiologist Heenam Stanley Kim, Ph.D, from Korea University’s Laboratory for Human-Microbial Interactions, in Seoul, examined emerging evidence suggesting that poor gut health adversely affects COVID-19 prognosis. Based on his analysis, Kim proposed that gut dysfunction — and its associated leaky gut — may exacerbate the severity of infection by enabling the virus to access the surface of the digestive tract and internal organs. These organs are vulnerable to infection because they have widespread ACE2 — a protein target of SARS-CoV-2 — on the surface.”There seems to be a clear connection between the altered gut microbiome and severe COVID-19,” Kim said.

J&J Covid-19 Vaccine Appears to be Safe
A total of 800 adults aged 18 to 55 or aged 65 and up were randomized to various combinations of low-dose or high-dose vaccines or placebo, given 56 days apart.
Adverse events were common, with fatigue, headache, myalgia, and injection-site pain reported most often. At day 29 after the first dose, the seroconversion rate was 99% or more in the younger cohort across dosing groups. Older vaccine recipients had a 96% seroconversion rate. At 57 days after the first dose, antibody titers had increased further.

The J&J vaccine is in a multi-center, placebo-controlled, phase 1–2a trial. Here’s the link to the NEJM article https://www.nejm.org/doi/full/10.1056/NEJMoa2034201
From Stat Phase 3 results are coming soon.
There are two Phase 3 studies running. A 40,000-volunteer study of the one-dose vaccine, conducted in the U.S., is set to read out in the next two weeks. A second, equally big study is being conducted using the same vaccine given as two doses, each administered 57 days apart, in case the vaccine does not prove effective in a one-dose regimen or there are other advantages, such as the durability of the vaccine, to giving a second dose.

And from the Medscape article.
Unlike the Pfizer/BioNTech and Moderna messenger RNA vaccines, the Johnson & Johnson product is a recombinant, replication-incompetent adenovirus serotype 26 (Ad26) vector encoding a full-length and stabilized SARS-CoV-2 spike (S) protein.

Why PTSD May Plague Many Hospitalized Covid-19 Survivors — Smithsonian Magazine
Scientists warn about the likelihood of post-traumatic stress disorder for patients discharged from the intensive care unit.
Covid-19 isn’t the first epidemic to cause a domino effect of persisting psychiatric health problems across a population. The current pandemic has been compared to the severe adult respiratory syndrome (SARS) outbreak in 2003 and the Middle East respiratory syndrome (MERS) outbreak in 2014 in Saudi Arabia—both diseases caused by coronaviruses. In an analysis of international studies from the SARS and MERS outbreaks, researchers found that among recovered patients, the prevalence of PTSD was 32.2 percent, depression was 14.9 percent and anxiety disorders was 14.8 percent.
Why PTSD May Plague Many Hospitalized Covid-19 Survivors — Science | Smithsonian Magazine
The entire article is worth reading. And from The BMJ probable PTSD in hospital workers too.
Nearly half of intensive care unit (ICU) and anaesthetic staff surveyed for a study reported symptoms consistent with a probable diagnosis of post-traumatic stress disorder (PTSD), severe depression, anxiety, or problem drinking.1
The preprint, produced by researchers at King’s College London, aimed to get a picture of the rates of probable mental health disorders in ICU and anaesthetic staff in six English hospitals during June and July 2020.
