Yesterday, commenter Edward R. Bonderenka wrote this:
As for the efficacy of the injection. I heard this morning that Israel, thoroughly injected, is seeing an upswing in ChiVi.
Now I hear it’s the Delta Variant (I shudder in fear).
But the injections were good against the DV.
Are they making it up as they go along?
I think the point of that comment was to say that the vaccine isn’t especially protective. It seems to me that the “shudder in fear” part might be sarcastic. But whether it’s sarcastic or not in that particular comment, “shudder in fear” is a good description of the effect that news of the Delta variant has on a lot of people, including a lot of people I know.
And it does seem as though quite a few authorities are itching to lock us down again, or at least to get us to all wear masks again.
It’s relatively early at this point in the life history of the Delta variant, but so far when I look at the actual numbers I see no cause for alarm. As has been true for the entire course of the pandemic, it’s the serious cases and the deaths that matter, and so far the rise in US cases is small according to the chart of cases per day. As for the rise in deaths, we only have data up to about three weeks ago, and there was no rise at that point.
But let’s take Israel, the country that was the subject of the comment. Israel is a good example because it’s compact and it’s easier to see the overall picture, plus it has a high percentage of vaccinated people.
The population of Israel is approximately 9,228,000. About 10% are over 65, and from this chart it seems that about another 450,000 are between 60 and 65 (that would add another 4.8%). So by my quick figuring, the total population over 60 in Israel would be about 1,373,000.
Of that 60-and-over group, more than 90% are fully vaccinated. Let’s lowball it and say that it’s 90%, which would mean that 1,235,700 are vaccinated in that age group. The Pfizer vaccine (used in Israel) is considered to be 95% effective. So I would conclude that 61,785 people over 60 in Israel who have been vaccinated would be expected to be susceptible to getting COVID despite the vaccine.
In populations over 60, what percent tend to have cases serious enough to be hospitalized? In the early days of the COVID pandemic (when there wasn’t good treatment and testing wasn’t so widespread), it was found that between 22% and 34% of people over 60 who got COVID needed hospitalization. I can’t find more recent statistics, but I’m pretty sure it’s a considerably smaller percentage at this point. I remember reading at one later time that it was 10% in the over-60 age group. So I’ll use that 10% figure.
If you look at the Worldometer charts for Israel, you’ll see that although case numbers have had a slight uptick there, they are still very low. Deaths haven’t even had an uptick (although deaths trail reporting of cases, of course).
Here’s an article describing the situation in Israel at present. Right now in the entire country there are 121 hospitalized COVID patients (it doesn’t say whether “from” or “with”) and 61 of them are in serious condition. All but one are over 60, and the other person is close to 60. There’s no information about their state of health otherwise, or their age distribution within that over-60 group. But this is a minuscule portion of the 61,785 Israelis in that age group fully vaccinated and vulnerable, of whom at least 6,179 might be expected to be hospitalized if they were to contract COVID.
Then there’s this:
One month ago, there were just 19 serious cases in the country; Sunday’s figure of 61 is the highest in two months. At its peak in late January, there were more than 1,000 serious cases.
So the caseload is still very low, even comparatively speaking. What’s more – and this is an important part:
The Delta variant is believed to be more successful in bypassing the COVID vaccines than previous strains of the virus. Health Ministry figures released in early July indicated that the Pfizer COVID vaccine is only 64% effective in preventing infection, but it remains 93% effective at preventing hospitalization and serious symptoms.
Some health officials cast doubt on these figures, noting that they were gathered only over a period of a month, and they maintain that the Pfizer vaccine is actually more effective against Delta than claimed. Nevertheless, Pfizer cited data from Israel in seeking authorization from the US Federal Drug Administration for a third booster dose of its vaccine.
Boosters are only planned to be given to people with extra health problems.
So it seems that the vaccine doesn’t protect perfectly, nor did anyone ever say it did. But it protects pretty well, especially against serious COVID. But that doesn’t mean such cases don’t happen in fully vaccinated people. They do and they will. The real question is whether their numbers will increase significantly and especially past the point that is to be expected given the fact that vaccines all have a certain failure rate. So far the numbers are not bad.
Part of the panic about this is that the MSM isn’t doing a good job of explaining the statistics. But what else is new? They have a vested interest in panic, too. And of course the Biden administration and some local authorities are ramping up the “Unvaccinated people are killers!” routine.
From the start COVID has been utterly politicized, which I consider reprehensible. From the start there also has been so much lying and coverup (as well as bona fide confusion) that it becomes harder rather than easier to sort out the wheat from the chaff. Social media and government officials (but I repeat myself) who purport to tell us what is “misinformation” and what is not have utterly failed to earn our trust. So apparently it’s up to us to figure out what the statistics actually mean, and that’s far from easy.
[ADDENDUM: I’ll add that headlines saying something like “COVID cases increase among fully vaccinated people” are confusing and even misleading for many people. Of course such cases are increasing among the fully vaccinated. More people have been fully vaccinated, and as I said in my post, at least 5% of the vaccinated will be susceptible to COVID. So as a greater percentage of the population becomes vaccinated, cases will increase among the vaccinated. But most people don’t think that through, and they conclude that the vaccine isn’t helping them against the new variant.]
