2 lines overlapping for Alpha = ~2% CFR
Same for Delta & Omicron = ~0.3% CFR
Note the differences in Y-axes.
Most seniors got vaccinated after the peak of Alpha wave. Others during the Delta wave.
1/
Omicron wave is likely to peak next wk (likely already did in southern/western 1/3 of the country), so deaths likely to peak in late Feb. Looking like it'll be the deadliest wave so far.
2/
Roughly,
Spring '20: 1k
Summer/Autumn '20: 1k
Winter '20-'21: 7.5k
Spring '21 (Alpha): 7.5k
Summer '21 (Delta): 3k
Winter '22 (Omicron): ~800 so far.
Per case severity is clearly lower relative to pre-vaxx peaks, but high transmissibility makes that less relevant.
3/
If this wave kills 10k, deaths per mil will reach ~230. Not great, but not horrible either. They'll be boosting a lot in Feb/Mar & 5-11 will get theirs in Mar, so that should help some. ~75% of 12-19 have been 2x vaxxed.
4/
Their initial plan to boost 8 mo post-2nd turned out to be a bit too ambitious. They tried to shorten the interval by ~1 mo, but couldn't quite get it done. Maybe a couple of wks earlier than the initial plan at best.
5/
Many reasons for this, but some were legal (Moderna boosters didn't get approved until mid-Dec).
Some were logistics (They had limited Pfizer doses & failed to distribute Moderna boosters, which they had more of, quickly).
6/
Others were political. The prev. vaxx minister was a popular politician who knew how to get things done. The current one is just an useless figure head, as the current admin took the power/control over vaccination back to PM's office & MHLW.
7/
JPN doing so well in Oct~Dec probably made ppl, incl. politicians & bureaucrats, a bit too complacent. Unlike S.Korea (or parts of Europe) which had a late Delta wave or US/UK w/ Delta plateau, there was no pressing need to boost early. Things were looking good back then.
8/
Still others were luck. Because Pfizer was approved much earlier than Moderna, most HCWs & seniors got Pfizer for 1st/2nd, & many seem to be hesitant to go w/ heterologous booster. Moderna having had production/delivery issues, etc. last yr sure didn't help.
9/
So many reasons they haven't gotten boosting up quickly & the current PM will be blamed for some of it, incl. for poor communication.
In any case, they seem to be finally getting their acts together on boosting, so hopefully they can keep it going.🤞

p.s.
For a look at how things are at prefecture/region level (which most won't see discussed in Eng), here's one from yesterday.
If anything S.Korea had more cases than usual, but fewer hospitalization. That makes sense, given that RSV is worse in <1. Delayed infection is a good thing.
What's ironic is that, if you follow the logic of "immunity debt" enthusiasts (charitably, tbf), you end up concluding that "freedom day" was even dumber than we already thought.
1/
For one, we know infection-induced immunity to many of these pathogens is fairly shot-lived. i.e. what happened yrs ago doesn't really matter.
2/
For another, not all pathogens are created equal. Some are more infectious/harder to control.
3/
Variant-specific PCR says suspected BA.5 was ~3/4 during 7/5~7/11. Almost all suspected BA.5 for the latest wk (7/12~7/18).
2/
Similar story for Kobe. L452R+ > 80% for 7/11~7/17 (1st table). Majority of sequences (2nd table) from 7/4~7/10 were BA.5. They show BA.2.12.1 under BA.2 in ( ), BA.2.75 in [ ].
Mini-thread on JPN Covid mortality data wrt "from" vs. "with".
(Meaning to do this since MHLW advisory board posted some useful data a month ago, so here it is.)
tl;dr: Covid is still the primary cause in majority of reported deaths & Omicron is bad.
1/
MHLW guideline essentially requires all deaths by Covid patients be reported, so the reported #s include some incidental cases. So what % is incidental?
2/
First, data from Kanagawa pref. (pop. 9.2m, 2nd largest) on the "primary" causes of death in Jan/Feb '22 (almost all Omicron).
Primary cause: 53.2%
Not primary cause: 32.1%
Undetermined: 14.7%
Note that "not primary cause" doesn't mean it wasn't a contributing factor.
A former Sanyo/Pana battery engineer, who was on the team that developed 18650 for Tesla, was interviewed by a Tesla fanboy/BEVangelist about the Battery Day.
TL;DR: Nothing ground-breaking. All are minor improvements IF they can work them out.
$TSLAQ
I might get around to summarizing the key points later. Meanwhile, here's the link. The guy is a Tesla owner & a bit of a fanboy himself, but I find his engineer's perspective interesting. Quite different from what lab scientists have said.
