It’s a failed policy that also flies in the face of science. A brave and compassionate few are resisting adults’ panic and not forcing little ones into masks. As of this writing, they include school boards in Ashe County, Avery County, Beaufort County, Carteret County, Catawba County, Newton-Conover City, Cherokee County, Cleveland County, Gaston County, Harnett County, Lincoln County, Macon County, Onslow County, Pamlico County, Pender County, Randolph County, Rockingham County, Rowan-Salisbury, Stanly County, Union County, and Yancey County. School boards in Camden County, Stokes County, Surry County, Wayne County, and Yadkin County made masks optional on a school-by-school basis.
This past week 97.7% of people in NC were estimated to pose no threat of passing along COVID-19 to anyone. Nevertheless, 39 out of 40 (97.4%) adult North Carolinians — and more than 19 out of 20 (95.5%) North Carolinians of any age — are estimated to have either been at least partially vaccinated or acquired natural immunity against Covid-19 or both. (See the end of this update for more discussion of those percentages.)
Here is the NC Threat-Free Index for the week ending January 31. All of the statistics generated for the NC Threat-Free Index are based on numbers provided by government sources. This link gives a detailed explanation of how each statistic is derived.
For the week ending January 31:
It’s been concerning, to say the least, to see case numbers rising so quickly among those considered fully vaccinated. In the month of December, fully 35% of Covid cases were in that group. Just over 5% came to those who had suffered a prior Covid infection and were not considered fully vaccinated. As this tendency became undeniable and in keeping with the CDC’s change of definition (see before and after), this index had to drop its previous description of “vaccine-induced immunity” in favor of “protection … through vaccination.”
This index has always used the “partially vaccinated” proportion in making its estimate, and that is because last April, Gov. Roy Cooper originally predicated relaxing most of his extreme emergency orders on having two-thirds of adults partially vaccinated. As of this writing, the proportions of partially vaccinated (75%) and fully vaccinated (71%) adults are very close.
It might be better at this point to focus on those who are fully vaccinated (71% of adults, 62% of the general population). As you can probably see, the estimates won’t change very much. They would be 97.0% of adults and 94.8% of North Carolinians (as opposed to 97.4% and 95.5%).
OK, what if we focused on the population who are fully vaccinated plus having received a booster (50% of adults, 47% of the general population)? It still doesn’t change the estimates very much: 94.8% of adults and 93.2% of North Carolinians.
Why? Because of the rise in North Carolinians with infections and therefore prior infections. Not just the official case numbers, the estimated number of actual infections. That’s a key distinction. The CDC in its most recent Estimated Covid-19 Burden report (updated Nov. 16) estimates that only 1 in 4 of Covid-19 infections are actually reported. The CDC’s estimate makes sense “if you consider, for example, one member of a family of four tests positive but the rest in the house feel sick, or also so many mild or asymptomatic infections that wouldn’t prompt a doctor’s visit.” Of course, someone’s natural immunity does not hinge on whether an infection was officially reported.
How the index handles estimating natural immunity under such uncertainty is this way (caution: description of math ahead): starting with the raw number of cases, it subtracts reinfections (to avoid double-counting), multiplies the remainder by four (the CDC multiplier), subtracts out deaths, and then discounts the remainder by the relevant vaccinated proportion (again to avoid double-counting). It then determines what proportion of the state’s population that figure is and adds it to the proportion of those vaccinated.
Some people, and not only witless ankle biters but even those who really should know better, seem to think that any mention of natural immunity somehow detracts from vaccination. Don’t be one of them. People have been contracting Covid-19 since before it was even officially recognized, and they include, among many, many others, health care workers and other “essential” workers who served the effete laptop class in the early months of Covid lockdowns. It is an especially grave injustice against them to support vaccine passports and similar policies that make no accounting for their natural immunity, and it’s based in the abject stupidity of believing that spread of a new virus depends upon whether enough people obey government orders fervently enough.
Hoping to ward off such silliness amid a Sept. 9, 2021, column on natural immunity, I specifically wrote the following:
It shouldn’t need to be said, except in this bizarre time in which things that “shouldn’t need to be said” are the very things that require clear statement, but such research and discussion is in no way meant to counsel against vaccination, which ought to be a personal decision based on a dispassionate weighing of personal benefits and costs without coercion. Nor is it to argue for deliberately contracting an infection.
I have personally witnessed this presentation of facts carom around inside someone’s skull until it comes out bruised and twisted into “Oh sure, go get Covid and die, then you’ll be immune!”
Even with that disclaimer, someone still responded, “So your answer is to get everyone sick the hell with the deaths, long term complications and the strain on our medical system.” Oblivious.
