J&J 66% effective

Which means you have a ⅓ chance of getting COVID-19:
A Brooklyn woman who managed to avoid catching COVID-19 throughout 2020 went down with the bug this month — three weeks after being vaccinated.
Ashley Allen, 31, spoke to The Post by phone while quarantined in her Williamsburg apartment and in between calls from city contact tracers.
The contact tracers “started asking me questions about what I was doing three weeks ago,” Allen said. “And I said I was getting vaccinated.”
Allen was thrilled when she was able to book an appointment for the one-dose Johnson & Johnson vaccine at the Javits Center on March 10.
Even after Allen was vaccinated, she was careful to always mask up when outside and wash her hands frequently.
“On Wednesday, March 31, I started feeling like a scratch, a tickle in my throat of some sort. It was super dry,” she recalled. “Then I kept having this dry cough. It kinda felt like I had allergies.”
As her cough persisted, debilitating fatigue set in. started getting really bad, to the point where I did go to City MD,” she said. “I thought I had Lyme disease. I spend a lot of time upstate.”
But a rapid coronavirus test on April 4, plus a second rapid test on April 5, showed COVID. A PCR test, which is more accurate, confirmed it.
The City MD staffer “asked when did you get your vaccine? And I said March 10, and she was like just shocked,” Allen said.
Allen’s case is rare, experts say, but not unheard of.
“The vaccine does not necessarily prevent you from getting COVID. It prevents you from being hospitalized or dying from it,” Dr. Kris Bungay, a Manhattan primary care physician, told The Post. “That is why we all still have to be careful.”

This raises some questions. What exactly do they mean by 66% efficacy? Does that mean that 66 out of 100 are immune? You could put them unmasked in a COVID ward and they won’t catch it? Does this mean that if you have had the vaccine, 66% of the time that you are exposed to the virus it won’t take? The other 34 times you will catch it? Do these numbers take into account actual exposures?

I don't see how you could track actual exposures with a large sample, maybe a few controlled cases, but in the real world it would be tough.
We need an App that can use the iPhone camera to see the vaccine real-time.

This is one of the best explanations of efficacy I've read. Also talks about how the numbers among various manufacturers are a bit apples and oranges.
