65. Yes. Absolutely you included people who don't use seatbelts

in measuring the efficiency of seatbelts. Efficiency measures how effective the safety measure is compared to doing nothing. As for vaccines - how many cases of COVID in vaccinate dpeople compared to how many cases when we do nothing. For seatbelts - pick a bad outcome (death, for example) - efficiency measures how many deaths for seatbelt wearers v. how many deaths would happen anyway..

Efficiency = bad outcomes with the proposed safety measure/bad outcomes when doing nothing.

For seatbelts: Deaths while wearing seatbelts/Deaths while not wearing seatbelts.
For vaccines: Death or serious illness (the study endpoints) with vaccines/death or serious illness for unvaccinated people.

Way too many people on DU need a high school mathematics class.

This is great news and indicates the vaccine is 99.7% effective. PSPS Aug 2021 #1
Not sure where you get that. Lucky Luciano Aug 2021 #2
Simple math: 16K breakthrough cases divided by 4.4 million fully vaxxed equals 0.36% PSPS Aug 2021 #4
That's not how efficacy is calculated. LisaL Aug 2021 #19

Again, tha thas nothing to do with vaccine efficacy. LisaL Aug 2021 #35
Sorry, but you're mixed up. PSPS Aug 2021 #44
You are just plain wrong. Ms. Toad Aug 2021 #64
Instead of repeating no it isn't over and over Leith Aug 2021 #51
Yes it does. It indicates that if you are vaccinated, you are unlikely to die even if you get it. Demsrule86 Aug 2021 #58
Of course it is. It's the very definition of efficacy. Please enlighten us with your wisdom. Thanks! PSPS Aug 2021 #45
You don't know the definition of efficacy. LisaL Aug 2021 #61
Ummmm? stopdiggin Aug 2021 #3

you're digging yourself deeper stopdiggin Aug 2021 #6
What are you talking about? The same figure is in the OP. PSPS Aug 2021 #9
Yup. Says it right there in the article. marybourg Aug 2021 #11
Prime number? I used to know. GulfCoast66 Aug 2021 #14
Wickipedia seems to say its a "rational number". marybourg Aug 2021 #16
It's a repeating decimal which makes rateyes Aug 2021 #18
The name would be you have no a clue. LisaL Aug 2021 #24
From the article. Phoenix61 Aug 2021 #29
And? LisaL Aug 2021 #34
Yes it is. How would you measure it? PSPS Aug 2021 #46
Seat belts. Lucky Luciano Aug 2021 #49
No, that measures the benefit of deciding to use a seat belt, not how well the seat belt works. PSPS Aug 2021 #52
Still bigly wrong Lucky Luciano Aug 2021 #53
LOL. Whatever. I'm done. You're just being a contrarian now. PSPS Aug 2021 #55
I was gonna say the same that you're being intentionally obtuse. Lucky Luciano Aug 2021 #56
You Are Pretty Much Right, Sir The Magistrate Aug 2021 #12
OMG. LisaL Aug 2021 #22
Apples And Oranges, Ma'am The Magistrate Aug 2021 #38
No no no Lucky Luciano Aug 2021 #39
See No. 38 Above, Sir The Magistrate Aug 2021 #40
Your last point above (post 38) is the key one. +1 Lucky Luciano Aug 2021 #50
You don't know how to do these calculations. LisaL Aug 2021 #21
From the article. Phoenix61 Aug 2021 #30
It doesn't matter how many times you repeat this. LisaL Aug 2021 #36
Geesh! How woould you measure it? PSPS Aug 2021 #47
Yes. Absolutely you included people who don't use seatbelts Ms. Toad Aug 2021 #65
No, it's not. LisaL Aug 2021 #20
131 have died? PatSeg Aug 2021 #7
wear a mask, vaccinate; let the experts fight the lunatics with their wrong numbers cadoman Aug 2021 #8
Even if we can get some of the reluctant ones PatSeg Aug 2021 #10
Even one death is disturbing. But if vaccinated in MA driving is now more dangerous GulfCoast66 Aug 2021 #15
"...But for a math guy it does the opposite...", +1 uponit7771 Aug 2021 #17
It depends. How many of the unvaxxed died from covid. That's important to compare mucifer Aug 2021 #37
Yes, the statistics are pretty incomplete PatSeg Aug 2021 #41
Out of 4.4 million! If you're one of the dead marybourg Aug 2021 #48
Yes, I agree PatSeg Aug 2021 #57
That actually great news for we vaccinated folks. GulfCoast66 Aug 2021 #13
40% of infections are breakthrough is good news? LisaL Aug 2021 #23
In populations with a high rate of vaccination Phoenix61 Aug 2021 #31
In a universe with very high vaccination rates still practicing social distancing. That universe. GulfCoast66 Aug 2021 #33
Yes, this article had good news and I note you rounded up the true figure. Demsrule86 Aug 2021 #59
I didn't round anything up. LisaL Aug 2021 #62
This Universe ProfessorGAC Aug 2021 #60
compared to being unvaccinated - yes. stopdiggin Aug 2021 #63
I Know EXACTLY What This Thread Is About ProfessorGAC Aug 2021 #66
the POINT, sir stopdiggin Aug 2021 #68
Massachusetts seems to have more of a problem with breakthroughs than other areas. Scrivener7 Aug 2021 #25
65% of MA is fully vaccinated... So I'm not sure how to take that 40% Azathoth Aug 2021 #26
Was the mortality rate of the unvaccinated mentioned somewhere? ecstatic Aug 2021 #67
No, but it seems likely that mortality rate will follow breakthrough infections rise Azathoth Aug 2021 #69
I want more context behind the numbers genxlib Aug 2021 #27
The key information is that 40% of cases are in the 65% of vaccinated people. Klaralven Aug 2021 #32
MA is interesting because with such a large number of vaccinated persons... Hugin Aug 2021 #42
I couldn't find data on hospitalization and death rates, but those numbers are more favorable Klaralven Aug 2021 #43
Yay! One of the few that seems to get basic math! Lucky Luciano Aug 2021 #54
