A Call for More Proportionality in Pandemic Coverage

Excerpt:

My late wife spent the last two and half years of her life in a nursing home with a form of early onset dementia. While she was in her fifties, almost everyone else there was elderly. In each of the three winters she was in the home, the place was closed to visitors at some point because of flu. This added heartbreak to heartbreak, but it was entirely reasonable. Nearly three in four flu deaths in the last pre-pandemic season occurred among seniors. Someone aged 65 or more who contracted the flu had a chance of dying of it of about one in 120. (By contrast, while more than 85% of the breakthrough deaths are among those over 65, the COVID death rate for fully vaccinated seniors is one in about 25,000.)

That is to say that the risk of death from flu in a nursing home was almost a thousand times as large as the risk of death from COVID to the overall vaccinated population, and the risk of dying from the flu if you caught it as a senior was more than 200 times greater than the risk from COVID if you are currently disease-free, similarly aged and fully vaccinated.

On the Interpretation of Vaccine Efficacy Rates

Excerpt:

With COVID-19 vaccines now being widely available in the U.S., I’ve seen various interpretations of vaccine efficacy rates. As one example, the paper disseminating the study on the efficacy of BioNTech and Pfizer’s vaccine BNT162b2 states in its results section:

BNT162b2 was 95% effective in preventing Covid-19

The intent of this post is to clarify the interpretations of such numbers.

Wealth and Insurance Choices: Evidence from US Households

Graphic:

Abstract:

Theoretically, wealthier people should buy less insurance, and should self-insure through saving instead, as insurance entails monitoring costs. Here, we use administrative data for 63,000 individuals and, contrary to theory, find that the wealthier have better life and property insurance coverage. Wealth-related differences in background risk, legal risk, liquidity constraints, financial literacy, and pricing explain only a small
fraction of the positive wealth-insurance correlation. This puzzling correlation persists in individual fixed-effects models estimated using 2,500,000 person-month observations. The fact that the less wealthy have less coverage, though intuitively they benefit more from insurance, might increase financial health disparities among households.

Is life insurance a human capital derivatives business?

Abstract:

Life and disability insurance, as well as annuities, traditionally have been analyzed as products providing protection against random losses. This article proposed that these products can be viewed as derivative instruments created to address the uncertainties and inadequacies of an individual’s human capital, if human capital is viewed as a financial instrument. In short, life insurance (including disability insurance and annuities) is the business of human capital securitization.

The Lab-Leak Theory: Inside the Fight to Uncover COVID-19’s Origins

Mary Pat Campbell

Excerpt:

Wuhan is also home to China’s foremost coronavirus research laboratory, housing one of the world’s largest collections of bat samples and bat-virus strains. The Wuhan Institute of Virology’s lead coronavirus researcher, Shi Zhengli, was among the first to identify horseshoe bats as the natural reservoirs for SARS-CoV, the virus that sparked an outbreak in 2002, killing 774 people and sickening more than 8,000 globally. After SARS, bats became a major subject of study for virologists around the world, and Shi became known in China as “Bat Woman” for her fearless exploration of their caves to collect samples. More recently, Shi and her colleagues at the WIV have performed high-profile experiments that made pathogens more infectious. Such research, known as “gain-of-function,” has generated heated controversy among virologists.

…..

By spring of 2021, the debate over COVID-19’s origins had become so noxious that death threats were flying in both directions.

In a CNN interview on March 26, Dr. Redfield, the former CDC director under Trump, made a candid admission: “I am of the point of view that I still think the most likely etiology of this pathogen in Wuhan was from a laboratory, you know, escaped.” Redfield added that he believed the release was an accident, not an intentional act. In his view, nothing that happened since his first calls with Dr. Gao changed a simple fact: The WIV needed to be ruled out as a source, and it hadn’t been.

CDC’s slow, cautious messaging on Covid-19 seems out of step with the moment, public health experts say

CDC’s slow, cautious messaging on Covid-19 seems out of step with the moment, public health experts say

Excerpt:

When the CDC issued new guidelines recently on when people still need to wear masks, the guidelines were seen as so conservative that they prompted a primetime rant on “The Daily Show.”

“I know science is difficult … but who’s running messaging at the CDC?” asked the show’s host, Trevor Noah.

Some public health experts are asking the same question. Most experts interviewed for this story say the agency has struggled to take advantage of the latest scientific findings to communicate as rapidly as possible with the American public. And when the guidance is issued, it tends to be overly cautious.

….

Still, public health officials say the conservative nature of the agency’s approach to Covid is a marked departure from how it deals with other major public health issues, like HIV and opioid use disorder.

…..

Multiple experts told STAT that they fear the CDC’s recommendations are becoming irrelevant for most Americans. They worry, too, that guidelines, like the CDC’s advice on masking, so seriously underplay the benefits of getting vaccinated that they risk dissuading people from getting a shot in the first place.

Insuring Another Disaster

Mary Pat Campbell
Insuring Another Disaster

Excerpt:

Leave it to California lawmakers, however, to cast aside thousands of years of complex commercial history in a misguided attempt to fix an admittedly legitimate insurance problem. Thanks to Proposition 103, a 1988 ballot measure, California already has a distorted insurance market that gives the insurance commissioner czar-like powers to approve rate increases and impose rate decreases.

Because of that law, insurers have a tough time adjusting rates to manage their risks. It’s a long, cumbersome, and antagonistic government process to adjust rates. Their other lever for ensuring solvency is to reduce their underwriting risks by, say, not writing fire-insurance policies to homeowners who live in high fire-risk areas or car insurance policies to drivers with multiple DUIs.

….

Instead, California Assemblymember Marc Levine, D-Marin County, has introduced Assembly Bill 1522, which would prohibit insurers from canceling insurance policies solely because a home or business is located in a high-risk wildfire area. It epitomizes California’s economically illiterate edict approach.

A Misleading C.D.C. Number

Mary Pat Campbell

Link: https://www.nytimes.com/2021/05/11/briefing/outdoor-covid-transmission-cdc-number.html

Excerpt:

When the Centers for Disease Control and Prevention released new guidelines last month for mask wearing, it announced that “less than 10 percent” of Covid-19 transmission was occurring outdoors. Media organizations repeated the statistic, and it quickly became a standard description of the frequency of outdoor transmission.

….

That benchmark “seems to be a huge exaggeration,” as Dr. Muge Cevik, a virologist at the University of St. Andrews, said. In truth, the share of transmission that has occurred outdoors seems to be below 1 percent and may be below 0.1 percent, multiple epidemiologists told me. The rare outdoor transmission that has happened almost all seems to have involved crowded places or close conversation.

Saying that less than 10 percent of Covid transmission occurs outdoors is akin to saying that sharks attack fewer than 20,000 swimmers a year. (The actual worldwide number is around 150.) It’s both true and deceiving.

The Pandemic Will Likely End In One Of These Four Ways

Mary Pat Campbell

Link: https://www.buzzfeednews.com/article/danvergano/coronavirus-pandemic-vaccines-endings?utm_source=digg&amp%3Butm_medium=email

Excerpt:

By June, most US adults get vaccinated. The shots halt the spread of SARS-CoV-2, even the more transmissible variants. And people feel safe shopping, traveling, and visiting each other, almost like they did before the pandemic.

This is the best outcome — and it isn’t completely far-fetched. Half of US adults have received at least one shot. Even with Johnson & Johnson’s vaccine paused, more than 3 million shots are being administered a day; at that rate, every adult American could receive one by late June.

Israel offers a glimpse of this future. There, a fast-paced campaign had immunized more than half of the population by mid-April. The results have been striking in the country of 9 million, with new cases falling to around 200 a day, 2% of the January peak. Starting this weekend, an outdoor mask mandate will be lifted.

Vaccine Efficacy and the Immunity Time Spans

Mary Pat Campbell

Link: https://polimath.substack.com/p/vaccine-efficacy-and-the-immunity

Excerpt:

Let’s refer back to the Pfizer study submitted to the FDA. In that study, 18,555 people were vaccinated and 18,533 people received the placebo injection. In these groups, 7 days after the second dose was administered, we saw that the vaccinated group got infected at only 5% the rate that the placebo group was infected.

Furthermore, this is the number of cases we see over the course of a two month study. So those 9 people out of 18,555 were not symptomatic and infectious that whole time, but only for a few weeks.

So, to take CNN’s example and re-imagine it for the reality we have with this data.

Let’s say 1 million people are travelling. If everyone is unvaccinated (and the window of infection is roughly one week), there will be about 1,100 infected travelers.

If, however, everyone is vaccinated, there will be about 60 infected travelers and their chance of infecting you (my dear vaccinated friend) is reduced substantially.
