Vaccinated with Pfizer are 3 and half fold less likely to catch delta than unvaccinated.
This kinda stuff drives me batty. "3½ times less likely" reminds me of laundry detergents claiming "35% cleaner!".
Just exactly WHAT does it mean?
If an unvaccinated person is 50% "likely" (wtf does THAT even mean? Under what circumstances are they 50% "likely"? How is it possible to know the average chances of ALL unvaxed under ALL conditions?) to get Covid, what is 3½ times less likely than that? Is it (50/3.5)% likely? Is it (50^-3.5)%? Maybe it's (.5^3.5)%?
Maybe it's just meaningless, baseless pablum?
Personally I think (.5^3.5)% makes the most sense, but I'm sure it could just as easily mean (50/3.5). The difference is only a bit more than 50% (about 8.8% vs 14.3%)
HELP, LOREN!!! (or some math person)
