#3Does this take into account that folks in Israel received their shots a while ago?

#439% effective against infection, but the big sticking point is that it "Largely prevents severe illness"...ie keeping people out of the hospital. That is the crucial need right now with the delta spread.

#5Need to come up with a Nasal Spray version. The mucosal immune system represents the body’s first line of defense and makes up most of the immune system and should be more effective than an intramuscular shot.

Researchers even observed the nasal vaccine to be more effective than if administered into the muscles, Damron said. He explained that a high amount of IgA antibody gets released into the nose and lungs, forging a wall of protection at the site where viruses begin to replicate.

My understanding is that it's pretty clear that vaccine do not do a good job at preventing infection (i.e. testing positive and/or having cold-like symptoms), Delta or not. I don't think they were ever advertised as such.

#7This is old news:

Also, the 39% number is the average for people vaccinated between January and July. For people vaccinated in January, the Pfizer shot is only 16% effective against the delta variant (scroll down to last page):

Protection against severe illness is still above 85% though and declines only slowly. Besides, people vaccinated in January were mostly elderly.

This is the media "grift" I absolutely can't believe. The vaccine IS preventing people from dying and it's largely known that the vaccine doesn't prevent infection or spread. That said, GET THE VACCINE, I do not intend for this to sound like I'm condoning any kind of anti-vax narrative!
Political fluff is expected, but keeping millions of people afraid and irate about information that deeply pertains to both their physical and mental health for what gain?

The 39% is against getting an infection, and I believe that includes the ability to transmit the infection on. It definitely is crucial that Re (R0 modified by measures like vaccines and masks) be kept below 1 if at all possible.
The preventing severe illness is still holding pretty firm, but not as strong as against other variants. Still a very good chance. And preventing hospitalizations is even stronger.

Correct based on my understanding. But sadly I see people quoting all the time (on social media) that it prevents infection. So there's probably a fair bit of misconception out there
