Why did they survey 5 million people? That is a huge waste of time and effort. Accurate results could be found with a much smaller sample size.
If you read the study they pared it down to 500,000 people. They also had people self identifying what education level they are so there was no actual control against people lying to make their opinion carry more weight.
Also, if you look at it, 2% of their sample size had PhDs, but only 1% of the population at large in the US have a PhD in reality. Even fewer than that percentage have a science focused PhD. Also, 13% or so of the 500,000 responses they chose had an undefined education level.
In short, the study is complete garbage, and even more so since it hasn't been peer reviewed. My brother tried pulling that study on me.
I'm starting to feel really confused by all the contradictory info coming out of the various government / health / media institutions.
Does the vaccine actually stop transmission?
If it does, then why are the number of infections rising when the majority of people are vaccinated?
If it doesn't, then why all the scapegoating of un-vaccinated people?
Does it just not work on the Delta version?
@Movies, to answer your question, yes, it stops transmission of certain variants, but from what I understand, not the Delta variant. At the time that the vaccines were developed, it wasn't known that the Delta variant was the predominant variant in the US, and there was really no way to know.
The important thing though, is that it still protects against transmission of other variants, so it's still very much worth getting, and it lessens the symptoms of the Delta variant so it could very well still save lives.
Admittedly some of my explanation may be slightly off, like maybe it does stop transmission of the Delta variant. I've got a degree in Mechanical Engineering, so Biology and Chemistry aren't my strong suits. Luckily I'm married to a doctor of Biochemistry and she helps shore up those weaknesses, but not everything she explains to me sticks in my head.
