I have a question for the folks who know about vaccine stuff. If a vaccine is said to be 90% effective does that mean that 9 out of 10 vaccinated people will not come down with a disease no matter how much they come into contact with it, or does it mean that every time a vaccinated person is exposed to it they have a 1 in 10 chance of getting sick?
Honestly, depends on who is saying it. Like, we're mostly seeing these effectiveness rates as filtered through several layers of reporting, any one of which might be misunderstanding a statistic.
The general sense, as I understand it, is something like this:
- Take a group of people and split them into two subgroups.
- Give one subgroup the vaccine, and don't give the other subgroup the vaccine.
- Wait a while.
- Check in with both groups and find out how many of them caught COVID during that time.
- X% of the no-vaccine group will have been infected. Y% of the vaccine group will have been infected (hopefully less than X%).
- The difference between X and Y as a percentage is the efficacy rate.
- Worked example: if 5% of the no-vaccine group caught COVID in the trial period, and 1% of the vaccinated group caught it, that's an 80% efficacy rate-- 1 is 20% of 5, so the rate of infection decreased by 80% of its original value.
My favorite musical instrument is the air-raid siren.
90% decreased rate of catching the disease in a trial group, as compared to an unvaccinated control group
so you're not immune but it takes a much larger/more prolonged/more unlucky exposure to viral particles for the infection to get a foothold.
And if you do still get infected, the infections are on average much milder, but assume you're probably still contagious if this happens.

According to the NPR story I heard, 90% efficacy means that if a vaccinated person is in a situation where there's an X percent chance of catching the disease, then that chance goes down by 90%. So if there's a 2% chance of a person getting sick in a given situation, then with the vaccine that goes down to 0.2%

Going to the horse races tonight. It's a really big open concourse and a weeknight so we won't be crowded in close with a bunch of people.

I wasn't budgeted for that tonight but this guy I met by the cages said that for a marginal fee, he and his associates would cover my bet! Wish me luck!

Today I went out and had lunch in a restaurant and we did that Oklahoma thing where everyone's phone blows up at once and then we're all relieved that it's an Amber Alert and not a tornado.
Don't look at me like that, the kid's fine. Anyway, nature is healing.
Neighbor informed me that apparently my delivery of two CPAP mask inserts were stolen while I was away over the weekend. I take solace in the fact the thief got a worthless piece of plastic that has no resale value but also I kinda need those replacements because they're already late due to Apria sending me size M instead of L for my big face the first time.
I just got a different CPAP mask myself and trying to get it adjusted right reminds me of when I was untreated and when I was adjusting to using the machine at all! I'm barely sleeping and it kinda hurts!
Getting that tired to my bones feeling is "fun"
At least I actually had dreams last night. One was weird. There was a classroom and we had a big green toad that got loose but it started like splitting into multiple weirder reptile creatures that kept growing and splitting. Kinda freaky.

Oh damn, that reminds me, apparently my machine is part of the big Philips CPAP recall. I should probably react to that letter from my clinic asking for the serial number.
Oh I only just heard of that when I called the supply place about my new mask the other day, they had a prerecorded message about it, mine is a resmed though so I think I'm good.

Here's the link to where you can submit the S/N to your CPAP machine directly to Philips (under the Patients, Users, and Caregivers section):
I checked my machine in about a month ago and submitted my contact info; still waiting to hear back from Philips or my home medical company I'm renting my machine from on when a replacement is coming or how/where to send my machine for the fix.

Yeah, ResMed sent me an email directly saying "You may have heard some wild shit about cpaps on the news, none of that is us we don't even know what they're trying to do over at Philips, bunch of amateurs."
Didn't find what I hoped, but I got many teeth, an unexpected fossilized piece of coral, an equally unexpected fossilized shrimp burrow, and a small piece of prehistoric turtle shell!

That's neat. You're neat, and you live in a neat place, and you interact with that place in neat ways. If I'm ever in your neck of the woods, I will exchange beer and baked goods in exchange for a tour of that neck of those woods.

Is that a joke about not understanding horse betting or is it the name of an actual racehorse?
Fuck you I'll never tell.
I won a little bit of money but I don't know why your neighbors are celebrating.

Need some stuff designed or printed? I can help with that.

It's been a while, but the temperature and tide and timing are all aligning perfectly!
The destination!
Perfectly stable cliffs
Fossilized shrimp burrow
Fossilized Coral
Various Ray plates, shark teeth, and gastropods
Fossilized shark teeth. Mostly sand tiger shark
at some point I need to figure out shade and the like because I darn near burnt to a crisp today
I'd love to get to calvert cliffs for megalodon teeth but it's just a bit too far for an evening trip
