Covidpocalypse Now: an update

Most of the Covid news is about vaccines.

A second vaccine has passed the final non-red tape hurdle in the US, and will likely be authorized by the end of the week. Six million doses will be distributed, probably over the weekend or early in the week, to over 3,000 locations.

There is argument and discussion going on as to the lower age limit on the vaccines. So far everything seems authorized for 18 year olds and older. It will probably be a serious mistake if that isn’t adjusted very soon. Now, the kids who transmit the disease that kill grandma are anonymous. Once they are the main carriers, they will not be, and a spotty subgroup of an entire generation will be scarred. At least, we’ll be given by fate the name for that generation. The Marys (for Typhoid Mary).

Let’s talk about Pregnant and lactating women for a minute. There have been no systematic trials pertaining to pregnant women, so the FDA advice is vague. They say, “you decide.” The following are supportable facts:

1) There is evidence, subject to revision because it is not the focus of any systematic experimental study, that pregnant women are somewhat protected from getting Covid-19, but not to anywhere near the degree that they can flout caution.

2) There is evidence, again subject to revision, that when pregnant women do get Covid-19, they have a number of worse outcomes than other people of similar age. They may get sicker, and there is a possible risk of preterm birth.

3) Non-live vaccines are generally considered safe for pregnant women.

To manufacturers and health care providers, this may be more a mater of blame and liability than anything else. Of all the people who get the vaccine, some are going to get sick or die randomly even if the vaccine never causes an actual problem, and someone is going to sue somebody over something. The chance of such a suit winning probably goes up if the plaintiff is a pregnant woman or her survivors, or if a baby is born with a problem etc. etc. So, by saying “you decide” we just get on with it, is probably the thinking.

VERY IMPORTANT: We humans have a lot of misconceptions about immunity and pregnancy. A common falsehood is that immunity of the mother is passed on to the offspring. This is not true. Also, an in utero fetus does not get vaccinated when the mother gets vaccinated. A lot of people believe these things happen but they do not.

What does happen is that the mother’s immune products, if she’s got them, circulate in the fetus, and may even be found in the newborn for a while. But an infant does not have much of a functioning adaptive immune system, so there can be no development of long term immunity, and the magical immunity stuff we have spent so much time talking about can’t be passed on.

During lactation, some of this humeral immunity of the mother will be shared with the offspring via breast feeding. This, of course, is also temporary.

It has been a while since I’ve done a literature search on this, but last time I looked there were no studies that really examined how effective any of this passive immunity is. Our cultural love of breastfeeding, and rhetoric from pro-breast feeding organizations, have led many people to believe that mother to infant immunity (i.e. through breastfeeding and esp the passing on of colostrum) is powerful and highly effective. We don’t really know this.


In the US right now 2.9 million Pfizer doses (with second doses already accounted for) have been shipped. Moderna will ship over 5 million doses right away. According to Health and Human Services (a Trump Crime Family Joint) there will be enough doses to vaccinate everybody in the US by the end of June 2021. We await the replacement of the Deplorables with Biden appointees to confirm (or deny) that.

Can you pass Covid-19 on if you are vaccinated?

Nobody knows yet, but there is not really a useful “yes” or “no” answer to this. Here’s the story: What matters is the R0 value of the disease, right? How many people will get infected down the road if a particular individual is infected. More realistically, sort of, imagine a population of 1 million people, and 1,000 people freshly infected show up and there are no precautions taken. If that disease is Covid and the 1 million are not vaccinated, the next “generation” of infection will see more than 1,000 people infected, and the next generation, more than that, etc. as a wave of the disease spreads across the populations. SO, maybe, 1,000 gets you 1800, and that gets you 2500, and that gets you 4,800, and so on.

If most everybody is vaccinated, the whole point is that the chance of the virus being able to reproduce in you at all is lower, the time frame and intensity of that reproduction is shorted or lowered. Maybe to zero, but even if not, the R0 value is significantly lowered.

So, in the above scenario, with the population mainly vaccinated, 1,000 infected people gets you maybe 100 (max, that would b a lot) which gets you 10, which gets you zero, and Bob’s your uncle.

Your Normal Fourth

I read the news today, oh boy. To coin a phrase.

Here is what my local paper’s headline said: “Socializing is a must for many on the 4th.”

Digging in we find that “For some, it was a time to throw caution to the wind and reclaim normalcy as they headed to a lake cabins, parks and backyard barbecues…Across the state, Minnesotans are making their own decisions while health care and government officials hold their breath…”

The quest for normalcy is powerful enough to make people dishonest with themselves, so you get sentences of this form: “I heard the Virus did/didn’t really do this/that/other thing, so I guess it is OK if I whatever-whevever [fill in idiotic decision here].”

Let me tell you what normal is. You go a week without a funeral. Several weeks. Maybe months, or a year. Normal is not when one of your relatives, friends, work associates, one of the kids in your child’s class, or the parent of one of the kids, or the old person that lives two doors down but you never talk to much but they just took her away in the ambulance, or a checkout person who’s name you never knew, or two of the nurses at the hospital your kid was born in, etc. etc. … normal is not when one of those people dies on average about every 14 day or so (but sometimes with longer gaps, sometimes in clusters) at the peak of Your Local Epidemic.

If you want to achieve normalcy during the 365 days between moments of must, when you must do the thing that is least recommended by people who must be much smarter than you are, then you must not. This applies to gatherings on the fourth, it will apply to all the holidays throughout much of the year. Next winter holidays, like Christmas and New years, or before that, Halloween which seems to have become the local Spring Break party holiday among America’s 20-somethings, or the most traveled day of the year, Thanksgiving, if you must seek normalcy the grim reaper must seek your family and fiends.

And eventually, not your parents, cousins, children, or neighbors. But you. Ask not for whom the germ theory tolls.
